National Home Inspector Examination (NHIE) - Certified Home Inspector — Questions and Answers

Question 1: During a move-out inspection, the inspector notes that the tenant painted a bedroom bright red without permission. This should be documented as:

An unauthorized alteration potentially chargeable to the tenant for repainting (Correct answer)
A lease violation requiring immediate legal action
An improvement that increases property value
Normal wear and tear chargeable to the landlord

Correct answer: An unauthorized alteration potentially chargeable to the tenant for repainting

Unauthorized paint colors beyond neutral are not normal wear and tear; the cost to repaint to a neutral color can typically be charged against the security deposit.

Question 2: How does risk management apply to daily practice in Marketing & Advertising Strategies for Certified Home Inspector professionals?

Only through responding to incidents after they occur
By avoiding high-risk situations entirely
Through annual safety audits exclusively
Through proactive identification of potential hazards and implementation of preventive measures (Correct answer)

Correct answer: Through proactive identification of potential hazards and implementation of preventive measures

Effective risk management in Marketing & Advertising Strategies requires proactive hazard identification and preventive measures, not just reactive responses. This approach reduces incidents, improves outcomes, and protects both professionals and clients.

Question 3: A tenant installs a satellite dish on the exterior of the rental unit without permission. Under FCC rules, the landlord may:

Restrict placement to minimize damage but cannot prohibit the dish entirely if it serves only the tenant's unit (Correct answer)
Immediately require removal of the dish under any lease terms
Charge the tenant a monthly fee for the dish installation
Evict the tenant for lease violation without a cure period

Correct answer: Restrict placement to minimize damage but cannot prohibit the dish entirely if it serves only the tenant's unit

The FCC's OTARD rule limits a landlord's ability to prohibit small satellite dishes on areas the tenant controls, though reasonable restrictions on placement are allowed.

Question 4: A tenant requests an accommodation for a service animal under the Fair Housing Act. The lease prohibits pets. What is the correct response?

Require the tenant to relocate to a pet-friendly unit
Grant a reasonable accommodation by waiving the no-pets policy for the service animal (Correct answer)
Enforce the no-pets clause and deny the request
Charge the tenant a pet deposit for the service animal

Correct answer: Grant a reasonable accommodation by waiving the no-pets policy for the service animal

The Fair Housing Act requires landlords to make reasonable accommodations for persons with disabilities, including allowing service and assistance animals regardless of pet policies.

Question 5: What is the function of collar ties in roof framing?

They resist rafter spread and help prevent the roof from pushing outward on the walls (Correct answer)
They connect the ridge board to the top plate of the exterior wall
They provide a nailing surface for attic flooring and storage
They transfer roof loads vertically down to the ceiling joists

Correct answer: They resist rafter spread and help prevent the roof from pushing outward on the walls

Collar ties (or collar beams) connect opposing rafters near the ridge to resist the outward thrust that rafters exert on the wall plates.

Question 6: A home inspector observes that a gas furnace has a cracked heat exchanger. Why is this a critical safety defect?

It allows combustion air to escape before reaching the burners
It causes the furnace to short-cycle and trip the high-limit switch
It can allow carbon monoxide to mix with conditioned air circulated throughout the home (Correct answer)
It reduces heating efficiency by 10-15%

Correct answer: It can allow carbon monoxide to mix with conditioned air circulated throughout the home

A cracked heat exchanger can allow combustion gases, including deadly carbon monoxide, to enter the air distribution system and be circulated throughout the living space.

Question 7: What is the purpose of the flue gas spillage test performed near a draft hood on a natural draft furnace?

To verify the thermocouple is functioning correctly
To detect if combustion gases are backdrafting into the living area (Correct answer)
To test igniter spark timing
To measure furnace efficiency rating

Correct answer: To detect if combustion gases are backdrafting into the living area

A spillage test—typically using a match or smoke pencil near the draft hood—determines whether combustion gases are being properly exhausted or are spilling back into the living space.

Question 8: During a home inspection, the inspector notices that the lintels above several windows in a brick wall are made of wood and showing signs of decay. What is the structural implication?

Decayed wood lintels can no longer support the masonry above the openings, risking wall failure (Correct answer)
The concern is limited to moisture intrusion through the window frame
Decayed lintels only affect window operation and weatherproofing
Wood lintels are decorative only and their decay has no structural significance

Correct answer: Decayed wood lintels can no longer support the masonry above the openings, risking wall failure

Lintels are structural elements that support the masonry above window and door openings; decayed wood lintels can fail and allow the masonry above to crack or collapse.

Question 9: What roof-related condition commonly results from inadequate attic ventilation combined with excessive heat loss through the ceiling in cold climates?

Thermal bridging
Efflorescence
Interstitial condensation
Ice dams (Correct answer)

Correct answer: Ice dams

Ice dams form when heat escaping through a poorly ventilated attic melts snow on the roof surface, which then refreezes at the cold eave and can force water under shingles causing interior damage.

Question 10: During lease negotiations for a home inspector's office space, a 'base year' is established for operating expenses. What happens in subsequent years?

The tenant pays only the increase in operating expenses above the base year level (Correct answer)
Rent is frozen at the base year rate regardless of inflation
Annual rent automatically matches the base year CPI index
The landlord absorbs all cost increases above the base year amount

Correct answer: The tenant pays only the increase in operating expenses above the base year level

Once a base year is set, the tenant is responsible for their pro-rata share of any operating cost increases above that base year amount.

Question 11: A landlord wants to convert a rental property to condominiums. Which tenant protection is most commonly required?

Immediate eviction with 3 days notice
Automatic lease termination upon filing conversion paperwork
No protections; landlords can convert without tenant notice
Advance notice of conversion and right-of-first-refusal to purchase their unit (Correct answer)

Correct answer: Advance notice of conversion and right-of-first-refusal to purchase their unit

Many jurisdictions require landlords to provide advance written notice of condo conversion and offer existing tenants first right to purchase their units.

Question 12: Which standard of practice is MOST important for ensuring quality in Financial Analysis & Reporting?

Following evidence-based protocols while adapting to specific circumstances (Correct answer)
Strictly adhering to the same procedure in every situation
Using the most advanced technology available regardless of need
Minimizing documentation to focus on practical work

Correct answer: Following evidence-based protocols while adapting to specific circumstances

Evidence-based protocols provide a foundation of proven practices, but effective Certified Home Inspector professionals must also adapt their approach based on specific circumstances and individual case needs within Financial Analysis & Reporting.

Question 13: When comparing contractor bids for a repair identified in a home inspection report, which variance range is generally considered acceptable before recommending a third bid?

More than 50%
More than 10%
More than 5%
More than 20% (Correct answer)

Correct answer: More than 20%

A variance of more than 20% between two contractor bids typically warrants obtaining a third estimate to ensure a fair market price.

Question 14: During a roof inspection, the home inspector walks the surface and notices a spongy or soft feel underfoot in a localized area. What should the inspector conclude?

The felt underlayment has bunched up in that section during installation
The roof decking in that area is likely rotted or delaminated and requires further evaluation (Correct answer)
The trusses in that area are spaced farther apart than standard
The area has thicker insulation beneath the sheathing

Correct answer: The roof decking in that area is likely rotted or delaminated and requires further evaluation

A soft or spongy area underfoot on a roof typically indicates that the sheathing has been damaged by water infiltration, leading to rot or delamination of the OSB or plywood deck.

Question 15: What does AFUE stand for and what does it measure?

Auxiliary Furnace Usage Estimate — measures backup heat usage
Ambient Fuel Usage Equation — measures annual gas consumption
Air Flow Unit Evaluation — measures duct airflow capacity
Annual Fuel Utilization Efficiency — measures heating equipment efficiency over a season (Correct answer)

Correct answer: Annual Fuel Utilization Efficiency — measures heating equipment efficiency over a season

AFUE (Annual Fuel Utilization Efficiency) is a percentage representing how efficiently a furnace or boiler converts fuel to heat over an entire heating season.

Question 16: What is the significance of finding polyurethane foam injected into cracks in a poured concrete foundation wall?

Foam-injected cracks are sealed and require no further evaluation
The presence of foam indicates the crack was caused by chemical expansion of the concrete
Polyurethane foam injection is the approved structural repair for all foundation cracks
It suggests previous water intrusion repairs but does not address the underlying structural cause of cracking (Correct answer)

Correct answer: It suggests previous water intrusion repairs but does not address the underlying structural cause of cracking

Foam injection seals cracks against water infiltration but does not restore structural integrity, and the cause of the crack should still be evaluated.

Question 17: How does risk management apply to daily practice in Environmental & Safety Assessment for Certified Home Inspector professionals?

Through annual safety audits exclusively
By avoiding high-risk situations entirely
Through proactive identification of potential hazards and implementation of preventive measures (Correct answer)
Only through responding to incidents after they occur

Question 19: A home inspector identifies a failing septic system. Which financial factor is uniquely important to disclose for this finding compared to other defects?

The age of the septic tank lid
The potential inability to obtain financing if the system fails health department standards (Correct answer)
The annual inspection fee for the system
The soil percolation test cost

Correct answer: The potential inability to obtain financing if the system fails health department standards

Many lenders will not approve mortgages on properties with non-compliant septic systems, making financing unavailability a critical financial disclosure.

Question 20: What does 'thermal bridging' refer to in the context of building insulation?

Conductive heat transfer through structural elements that bypass the insulation layer (Correct answer)
Radiant heat gain through windows
Heat flowing through air gaps in insulation
Moisture migration through insulation

Correct answer: Conductive heat transfer through structural elements that bypass the insulation layer

Thermal bridging occurs when structural members like wood studs or metal framing conduct heat more readily than the surrounding insulation, reducing the overall thermal performance of the wall assembly.

Question 21: What is the primary concern when cellulose insulation becomes saturated with water due to a leak or flooding?

It compresses, promotes mold growth, and retains moisture causing long-term structural damage (Correct answer)
It immediately ignites due to combustion of its paper fibers
It releases toxic off-gases into the living space
It loses its fire-retardant treatment and becomes a code violation

Correct answer: It compresses, promotes mold growth, and retains moisture causing long-term structural damage

Wet cellulose compresses significantly, losing R-value permanently, and retains moisture that promotes mold growth and wood rot in surrounding structural members.

Question 22: Which of the following situations is most likely to constitute illegal housing discrimination under the Fair Housing Act?

Setting a minimum income requirement for all prospective tenants
Advertising a property as 'perfect for young professionals' only (Correct answer)
Requiring a security deposit from all tenants
Conducting background checks on all applicants uniformly

Correct answer: Advertising a property as 'perfect for young professionals' only

Advertising that signals a preference for tenants of a particular age group can constitute familial status discrimination under the FHA.

Question 23: During a home inspection, the inspector observes that a steel I-beam in the basement has significant rust and section loss. What is the primary structural concern?

Rust causes the beam to expand and crack surrounding masonry
Corroded steel beams are only a cosmetic concern
Section loss reduces the beam's load-carrying capacity (Correct answer)
Rust increases the weight of the beam beyond design limits

Correct answer: Section loss reduces the beam's load-carrying capacity

Section loss from corrosion reduces the cross-sectional area of the beam, directly decreasing its ability to carry loads safely.

Anode rod
Dip tube

Correct answer: Temperature and pressure relief (TPR) valve

The TPR valve is a safety device that opens to release water if temperature exceeds 210°F or pressure exceeds 150 psi.

Question 31: An inspector finds TPR valve discharge piping on a water heater terminates 6 inches above the floor. Why is this correct?

It is incorrect; discharge pipes must connect directly to a drain
The pipe should terminate at ceiling height to prevent burns
It allows visual confirmation of discharge while directing scalding water toward the floor safely (Correct answer)
Discharge piping does not need to terminate at any specific location

Correct answer: It allows visual confirmation of discharge while directing scalding water toward the floor safely

TPR discharge pipes should terminate between 6 inches and floor level to direct scalding water safely downward and allow observation of valve operation.

Question 32: What is 'retargeting' in digital advertising and how can a home inspector use it?

Updating ad creative every week to keep it fresh
Re-sending emails to contacts who unsubscribed
Showing ads to people who previously visited your website but didn't book (Correct answer)
Calling prospects multiple times until they respond

Correct answer: Showing ads to people who previously visited your website but didn't book

Retargeting serves ads specifically to previous website visitors, keeping the inspector top-of-mind with warm prospects who have already shown interest.

Question 33: A tenant vacates without notice and leaves personal belongings behind. What should a landlord do first?

Return the security deposit immediately
Immediately dispose of all items left behind
Change the locks and store belongings, following state abandoned property laws (Correct answer)
Sell the belongings to recover unpaid rent

Correct answer: Change the locks and store belongings, following state abandoned property laws

Most states require landlords to follow specific abandoned property procedures, including notice and storage periods, before disposing of belongings.

Question 34: When performing a sales comparison approach, an appraiser finds a comparable sale with a superior garage compared to the subject property. What adjustment is made to the comparable?

A negative adjustment is subtracted from the comparable's sale price (Correct answer)
The comparable is discarded from the analysis
No adjustment is needed for garage differences
A positive adjustment is added to the comparable's sale price

Correct answer: A negative adjustment is subtracted from the comparable's sale price

When a comparable is superior to the subject in a feature, a negative adjustment is made to the comparable to bring it in line with the subject's value.

Question 35: How often should HVAC filters typically be changed?

Once a year
Only when dirty
Every 6 months
Every 1 to 3 months (Correct answer)

Correct answer: Every 1 to 3 months

Correct answer: Missing or deteriorated chimney cap allowing rain entry

A missing or damaged chimney cap allows water, animals, and debris to enter the flue, creating fire hazards, moisture damage, and blocked draft conditions.

Question 37: An inspector notices that a ridge board in an attic has a noticeable sag. What structural issue does this most likely indicate?

The roof sheathing is delaminating and pulling away from rafters
The attic insulation is too heavy for the ceiling joists
Ridge boards are non-structural and sagging is always cosmetic
The ridge board is undersized or rafters are lacking proper collar ties (Correct answer)

Correct answer: The ridge board is undersized or rafters are lacking proper collar ties

A sagging ridge board indicates that the roof framing lacks adequate support, often because the ridge is undersized or collar ties/rafter ties are missing.

Question 38: What is the purpose of a mudsill (sill plate) in residential construction?

To act as a moisture barrier between the concrete and framing
To anchor the wood framing to the concrete foundation (Correct answer)
To distribute roof loads across the top of the foundation wall
To provide a level surface for installing hardwood flooring

Correct answer: To anchor the wood framing to the concrete foundation

The mudsill is the lowest horizontal framing member that is bolted to the foundation, anchoring the wood structure to the concrete or masonry.

Question 39: Which of the following would most directly increase a property's 'effective age' compared to its actual age?

Recent full renovation of all major systems
Consistent preventive maintenance over the property's life
Significant deferred maintenance and neglect (Correct answer)
A newly installed energy-efficient HVAC system

Correct answer: Significant deferred maintenance and neglect

Aluminum wiring carries less current than copper and must be upsized
Aluminum wiring is prohibited in all residential installations
Aluminum expands and contracts more than copper, causing loose connections and fire risk (Correct answer)

Correct answer: Aluminum expands and contracts more than copper, causing loose connections and fire risk

Aluminum wiring's greater thermal expansion compared to copper causes connections to loosen over time, creating arcing and fire hazards at standard receptacles.

Question 45: What is a common sign of foundation settlement?

Wall cracks and uneven floors (Correct answer)
Water stains on ceilings
Drafty windows
Peeling paint

Correct answer: Wall cracks and uneven floors

Foundation settlement occurs when the soil beneath the foundation shifts or compacts, causing the house to move unevenly. Common signs include visible cracks in walls (especially diagonal ones), sticking doors and windows, and floors that are noticeably out of level. These indicators suggest structural movement that requires professional assessment.

Question 46: A home inspector finds a pressure relief valve (T&P valve) on a water heater that has been removed and capped off. This is:

Acceptable if the water heater is less than five years old
A minor issue requiring only documentation
A serious safety deficiency that could result in a catastrophic explosion (Correct answer)
Normal practice in homes with high water pressure

Correct answer: A serious safety deficiency that could result in a catastrophic explosion

The T&P valve is the only safety device preventing a water heater from exploding under excessive pressure or temperature; disabling it is extremely dangerous.

Question 47: What is the significance of finding Federal Pacific Electric (FPE) Stab-Lok panels during a home inspection?

They are acceptable if breakers test properly with a circuit tester
They are modern high-capacity panels requiring no action
They must be immediately shut off during inspection
They have a documented history of breaker failure to trip, posing a fire hazard (Correct answer)

Kitchen faucet and outdoor hose bib
Shower, toilet flush, and laundry cold fill simultaneously (Correct answer)
Toilet flush and bathroom sink cold tap
Dishwasher cycle and bathroom hot tap

Correct answer: Shower, toilet flush, and laundry cold fill simultaneously

Running the shower, flushing a toilet, and filling the laundry simultaneously draws significant volume and reveals pressure drop issues that low-demand testing would miss.

Question 56: An inspector observes horizontal cracking in a concrete block foundation wall. This pattern most likely indicates:

Vertical settlement of the footing
Lateral soil pressure exceeding the wall's design capacity (Correct answer)
Normal concrete curing shrinkage
Thermal expansion of the block units

Correct answer: Lateral soil pressure exceeding the wall's design capacity

Horizontal cracks in block foundation walls are a serious indicator of lateral soil or hydrostatic pressure bowing the wall inward.

Question 57: When inspecting a heat pump, which defrost cycle symptom indicates normal operation?

Refrigerant leaking from the service port
The indoor fan shutting off permanently during defrost
Temporary steam rising from the outdoor unit during defrost (Correct answer)
Ice forming permanently on the outdoor coil

Correct answer: Temporary steam rising from the outdoor unit during defrost

Steam rising from the outdoor unit is normal during a heat pump defrost cycle as the reversing valve briefly switches to cooling mode to melt accumulated ice.

Question 58: What is the NEC requirement for the minimum wire gauge on a 20-amp branch circuit?

16 AWG copper
10 AWG copper
12 AWG copper (Correct answer)

Question 60: A home inspector's website has high traffic but low booking rates. Which of the following is the most likely cause?

The website is receiving too much traffic
The inspector's certifications are too advanced for the market
Poor user experience, unclear calls-to-action, or a difficult booking process (Correct answer)
The website is ranking too high in search results

Correct answer: Poor user experience, unclear calls-to-action, or a difficult booking process

High traffic with low conversions typically indicates the website fails to guide visitors toward booking through clear CTAs, trust signals, or an easy scheduling process.

Question 61: Which documentation practice strengthens the financial credibility of cost estimates in a home inspection report?

Estimating costs at national averages regardless of local market
Rounding all figures to the nearest $10,000
Limiting cost disclosures to items over $5,000 only
Citing local contractor quotes, cost databases, or industry cost guides as the basis for estimates (Correct answer)

Correct answer: Citing local contractor quotes, cost databases, or industry cost guides as the basis for estimates

Citing recognized cost sources (e.g., RSMeans, local contractor averages) lends credibility and defensibility to cost estimates in the report.

Question 62: A home inspector finds that counter-flashing at a chimney is embedded in the mortar joints but is not sealed with caulk or sealant. Is this acceptable?

Yes — but only if the flashing is galvanized steel rather than aluminum
No — counter-flashing must always be caulked at the top edge regardless of mortar embedment
Yes — properly tuck-pointed counter-flashing embedded in mortar is self-sealing and caulk is not required (Correct answer)
No — counter-flashing must be surface-mounted and caulked, never embedded in mortar

Correct answer: Yes — properly tuck-pointed counter-flashing embedded in mortar is self-sealing and caulk is not required

Counter-flashing that is properly embedded (regletted) into intact mortar joints forms a weather-tight seal without sealant; caulking is only required for surface-applied counter-flashing.

Question 63: Which insulation installation method delivers loose material pneumatically through a hose into attic spaces or enclosed wall cavities?

Blown-in (loose-fill) installation (Correct answer)
Roll-out installation
Rigid board installation
Spray-applied foam

Correct answer: Blown-in (loose-fill) installation

Blown-in or loose-fill insulation is delivered pneumatically, allowing it to fill irregular spaces and achieve uniform coverage in open attics or enclosed cavities where batts would be difficult to install.

Question 64: A home inspector finds a junction box hidden inside a wall with no accessible cover plate. What should be reported?

Junction boxes must remain accessible and have a cover plate per NEC (Correct answer)
Only outdoor junction boxes require cover plates
The box is fine if the wall material is non-combustible
The box is acceptable if the connections inside are made with wire nuts

Correct answer: Junction boxes must remain accessible and have a cover plate per NEC

The NEC requires all junction boxes to be accessible and covered to allow inspection and prevent contact with live connections.

Question 65: What is a cripple wall in residential construction, and why is it structurally significant?

A retaining wall that supports the weight of the chimney
A short stud wall between the foundation and first floor that can be vulnerable to racking during earthquakes (Correct answer)
A wall framed with undersized studs due to a construction error
Any wall with openings that interrupt the full-height stud layout

Correct answer: A short stud wall between the foundation and first floor that can be vulnerable to racking during earthquakes

Cripple walls are short wood-framed walls between the foundation and first floor that are especially vulnerable to lateral racking forces during seismic events.

Question 66: A buyer's agent asks the home inspector to provide a 'repair allowance' figure for negotiation. The inspector should:

Provide a precise negotiation number as a professional courtesy
Recommend the buyer deduct 10% of the listing price as standard practice
Decline and clarify that the report provides cost estimates, but negotiation strategy is outside the inspector's scope (Correct answer)
Contact the seller's agent to agree on a fair figure

Correct answer: Decline and clarify that the report provides cost estimates, but negotiation strategy is outside the inspector's scope

Home inspectors report findings and may estimate repair costs, but determining negotiation strategy or a final allowance figure is outside their professional scope.

Question 67: When inspecting a service entrance, a home inspector notes the service drop conductors are less than 10 feet above a driveway. What is the concern?

The conductors may interfere with radio signals
The conductors will corrode faster at lower heights

Oil staining is visible around the refrigerant line connections at the outdoor unit (Correct answer)
The outdoor unit is mounted on a wall bracket rather than on the ground
The system has two indoor heads connected to one outdoor unit
The outdoor unit makes a brief clicking sound at startup

Correct answer: Oil staining is visible around the refrigerant line connections at the outdoor unit

Oil staining around refrigerant line connections indicates a refrigerant leak, since refrigerant oil travels with the refrigerant and leaves visible residue at leak points.

Question 91: How does a 'buyer's market' typically affect negotiation on a home inspection report?

Inspection findings have no bearing on price negotiations in any market
Buyers have less leverage to request repairs since sellers have multiple offers
Sellers always refuse repair requests in a buyer's market
Buyers have more leverage to negotiate repairs or price reductions due to ample inventory (Correct answer)

Correct answer: Buyers have more leverage to negotiate repairs or price reductions due to ample inventory

In a buyer's market with high inventory and fewer competing buyers, buyers hold stronger negotiating power to request repairs or price concessions after inspection.

Question 92: Which insulation material commonly found in pre-1980s homes is highly fire-resistant but poses significant health hazards when its fibers are disturbed?

Fiberglass batt

Question 102: Which structural component typically supports floor joists?

Soffits
Studs
Headers
Beams (Correct answer)

Correct answer: Beams

Beams are horizontal structural members that span openings or support loads from above, transferring them to columns or walls. In floor systems, beams are typically used to support the ends of floor joists, which then carry the floor decking and live loads. This ensures the structural integrity of the floor system.

Question 103: When inspecting a septic system, which visible sign indicates the drain field may be failing?

Lush, green grass growing over the drain field (Correct answer)
Dry, cracked soil over the leach field
Multiple inspection ports capped with plastic covers
A cleanout cap above grade near the house

Correct answer: Lush, green grass growing over the drain field

Unusually lush or green grass over a drain field indicates that effluent is surfacing and saturating the soil rather than dispersing properly underground.

Question 104: A home inspector reviewing a property for valuation purposes notices deferred maintenance. How does this typically affect market value?

It only affects value if the inspector documents it formally
It generally reduces market value due to anticipated repair costs (Correct answer)
It has no effect if the home is structurally sound
It increases value by showing original features are intact

Correct answer: It generally reduces market value due to anticipated repair costs

Deferred maintenance signals future repair costs to buyers and appraisers, typically resulting in a downward adjustment to market value.

Question 105: What is 'highest and best use' as applied in property valuation?

The use that generates the least environmental impact
The legally permissible, physically possible, financially feasible, and maximally productive use of a property (Correct answer)
The use that requires the least maintenance from the owner
The use designated by the current homeowner at time of sale

Correct answer: The legally permissible, physically possible, financially feasible, and maximally productive use of a property

Highest and best use is the legally, physically, and financially justified use that produces the greatest value for a property.

Question 106: When setting an advertising budget, which approach is most appropriate for a home inspector in a competitive metropolitan market?

Set a fixed budget and never adjust it regardless of performance
Spend as little as possible and rely entirely on word-of-mouth
Allocate a percentage of projected gross revenue and track ROI by campaign (Correct answer)
Only advertise during slow winter months

Correct answer: Allocate a percentage of projected gross revenue and track ROI by campaign

Allocating a revenue percentage and tracking ROI allows for data-driven budget adjustments that maximize return and sustain competitive presence year-round.

Question 107: In which building areas should a home inspector pay the closest attention to proper vapor barrier installation to prevent insulation moisture damage?

Vented attic spaces above insulated floor assemblies
Garage ceilings not adjacent to living space
Interior partition walls between conditioned spaces
Crawl spaces, basements, and unvented cathedral ceilings (Correct answer)

Correct answer: Crawl spaces, basements, and unvented cathedral ceilings

Crawl spaces, basements, and unvented cathedral ceilings are high-moisture-risk areas where improper or missing vapor control leads to condensation, mold growth, and insulation failure.

Question 108: A home inspector observes that a p-trap under a bathroom sink is installed without a vent pipe. What issue should be documented?

Cross-connection hazard
Insufficient drain slope
Sewer gas infiltration risk (Correct answer)
Inadequate water pressure

Correct answer: Sewer gas infiltration risk

Without proper venting, negative pressure can siphon water out of the p-trap, allowing sewer gases to enter the living space.

Question 109: During inspection, an inspector finds wiring run through a gas furnace plenum. What is the concern?

Wiring in plenums must be in conduit regardless of cable type
Only aluminum wiring is prohibited in plenums
Plenum wiring is only restricted in commercial buildings
Standard NEC cables like Romex are not rated for plenum use and can emit toxic fumes in a fire (Correct answer)

Correct answer: Standard NEC cables like Romex are not rated for plenum use and can emit toxic fumes in a fire

Romex (NM-B) is not plenum-rated; in a fire, it can release toxic gases that spread through the HVAC system, requiring plenum-rated (CMP) cables instead.

Question 110: A landlord wants to enter a tenant's unit for a non-emergency inspection. What is typically required under most state landlord-tenant laws?

No notice is needed since the landlord owns the property
At least 24 to 48 hours advance written notice to the tenant (Correct answer)
A court order before every entry
The tenant must be present at all times during the entry

Correct answer: At least 24 to 48 hours advance written notice to the tenant

Most states mandate 24–48 hours written notice before non-emergency landlord entry to respect the tenant's right to quiet enjoyment.

Question 111: When a home inspector's report reveals significant structural issues, how does this typically affect the appraisal process?

The inspection report automatically voids the appraisal
Appraisers ignore home inspection reports; they conduct independent structural assessments
The lender may require repairs before the appraisal can support the loan amount, or the appraiser may note the condition as a value-impacting factor (Correct answer)
Structural issues only affect value in commercial properties

Correct answer: The lender may require repairs before the appraisal can support the loan amount, or the appraiser may note the condition as a value-impacting factor

Significant structural defects revealed in a home inspection can prompt lenders to require repairs as a condition of financing, and appraisers account for them in their value conclusion.

Question 112: What structural element connects rafters at the peak of the roof?

Ceiling joist
Truss plate
Ridge board (Correct answer)
Collar tie

Correct answer: Ridge board

The ridge board is a non-structural horizontal member located at the very peak of a sloped roof, where the tops of the rafters meet. It serves as a nailing surface for the rafters and helps align them during construction. While collar ties and ceiling joists also connect rafters, the ridge board is specifically at the highest point, forming the apex of the roof frame.

Question 113: An inspector finds that a wood deck ledger board is attached directly to a stucco-clad wall without flashing. The primary risk is:

The deck may vibrate excessively during use
The stucco will crack from the fastener load
The ledger may be over-spanned for the deck size
Water intrusion behind the ledger causing rot and structural failure (Correct answer)

Correct answer: Water intrusion behind the ledger causing rot and structural failure

Without proper flashing, water is trapped between the ledger and the wall, leading to hidden wood rot that can cause catastrophic deck collapse.

Question 114: When a conflict arises between standard procedures and a unique situation in Lease Negotiation & Terms, what should a CHI professional prioritize?

Safety and ethical obligations while seeking expert consultation (Correct answer)
Strict adherence to written procedures without exception
The most cost-effective solution available

Safety and ethics always take priority in Lease Negotiation & Terms. When standard procedures don't adequately address a unique situation, consulting with experienced colleagues or supervisors ensures both safety and professional standards are maintained.

Question 115: What is the purpose of the 'drip edge' flashing installed at the eave and rake of a shingled roof?

To provide a nailing surface for the first course of shingles
To create a thermal break between the roof deck and the gutters
To direct water away from the fascia and prevent capillary wicking under the shingle edge (Correct answer)
To anchor the ice-and-water shield at the eave in cold climates

Correct answer: To direct water away from the fascia and prevent capillary wicking under the shingle edge

Drip edge flashing projects water past the fascia board, preventing capillary action from pulling water back under the shingle overhang and causing rot to the fascia and soffit.

Question 116: Which factor is considered an 'external obsolescence' in property valuation?

Worn carpet throughout the home
A cracked foundation wall
Outdated kitchen appliances
A new highway constructed adjacent to the property (Correct answer)

Correct answer: A new highway constructed adjacent to the property

External obsolescence arises from outside the property's boundaries, such as nearby nuisances or infrastructure changes that reduce desirability.

Question 117: Which element of a home inspection website is most critical for converting visitors into booked appointments?

A detailed biography of the inspector's personal history
An extensive photo gallery of past inspections
A clear and prominent call-to-action with easy online scheduling (Correct answer)
A blog with daily posts about home maintenance

Correct answer: A clear and prominent call-to-action with easy online scheduling

A clear call-to-action with frictionless online scheduling removes barriers to booking and directly drives conversions from site visitors.

Question 118: A home inspector who also holds a real estate license must be especially careful about which ethical conflict?

Recommending contractors for repairs
Using inspection findings to negotiate a commission advantage or steer clients (Correct answer)
Charging different rates for buyers vs. sellers
Inspecting homes in jurisdictions outside their license area

Correct answer: Using inspection findings to negotiate a commission advantage or steer clients

Dual-licensed professionals must avoid leveraging inspection results for real estate transaction advantages, which creates a conflict of interest.

Question 119: Which of the following items typically carries the highest replacement cost and should receive priority financial disclosure in a report?

Weather stripping
HVAC system (Correct answer)
Bathroom caulking
Attic insulation top-up

Correct answer: HVAC system

HVAC system replacement is among the most expensive single repairs, often ranging from $5,000 to $12,000+, warranting clear financial disclosure.

Question 120: What documentation practice is considered essential in Property Evaluation & Analysis within the Certified Home Inspector field?

Recording actions, observations, and outcomes in real-time or as close to the event as possible (Correct answer)
Only documenting unusual events or complications
Using shorthand notes that can be expanded later if needed
Completing all documentation at the end of the workday

Correct answer: Recording actions, observations, and outcomes in real-time or as close to the event as possible

Real-time or near-real-time documentation in Property Evaluation & Analysis ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.

Question 121: Under a 'gross lease' structure, who typically pays for utilities, maintenance, and property taxes?

Landlord includes most or all operating costs in a single rent payment (Correct answer)
A property management firm covers all expenses from reserves
Both parties split costs based on square footage ratio
Tenant pays all operating expenses separately

Correct answer: Landlord includes most or all operating costs in a single rent payment

In a gross lease, the landlord bundles operating expenses into one rent figure, simplifying budgeting for the tenant.

Question 122: What is the minimum slope required for lot grading immediately adjacent to a home's foundation to promote proper drainage?

3 inches per 10 feet
1 inch per 5 feet
6 inches within the first 10 feet (Correct answer)
12 inches within 20 feet

Correct answer: 6 inches within the first 10 feet

Standard guidance requires a minimum 6-inch drop within the first 10 feet from the foundation to direct water away from the structure.

Question 123: When inspecting a chimney, a home inspector notices that the mortar crown (chimney cap) has cracks running from the flue liner to the edge. What should the report state?

The crown should be sealed or replaced to prevent water penetration and spalling (Correct answer)
The cracks are cosmetic and do not affect function
The flue liner should be replaced before the crown is addressed
Monitor annually; minor cracking is expected

Correct answer: The crown should be sealed or replaced to prevent water penetration and spalling

Cracks in the chimney crown allow water to enter the masonry assembly, causing freeze-thaw spalling that can ultimately compromise the structural integrity of the chimney.

Question 124: A home inspector observes that a gas furnace installed in a bedroom closet has no louvered door or combustion air provision. What is the primary concern?

Building codes prohibit furnaces in any closet space
The confined space will deplete oxygen needed for combustion, causing incomplete combustion and potential carbon monoxide production (Correct answer)

Question 141: What is a common sign of an overloaded circuit?

Warm light switches
Breaker tripping frequently (Correct answer)
Loose wiring
Buzzing outlets

Correct answer: Breaker tripping frequently

An overloaded circuit occurs when too many electrical devices are drawing more current than the circuit is designed to handle. The circuit breaker's function is to trip (open) and cut off power to prevent overheating of wires, which could lead to a fire. Frequent tripping is a clear indication that a circuit is overloaded and needs attention.

Question 142: What is the minimum roof slope typically required for standard three-tab asphalt shingles to be installed without special underlayment modifications?

1:12
4:12
3:12 (Correct answer)
2:12

Correct answer: 3:12

Standard asphalt shingles require a minimum 3:12 slope; below this pitch, water drains too slowly and can back up under shingle laps, causing leaks.

Question 143: During a routine inspection, an inspector finds the tenant has made improvements that increase property value without prior approval. How should this be handled?

Issue a lease violation notice immediately
Thank the tenant and grant a rent reduction
Demand immediate reversal of the improvements
Document the improvements, inform the owner, and review lease terms regarding alterations (Correct answer)

Correct answer: Document the improvements, inform the owner, and review lease terms regarding alterations

Documentation and owner notification are required; the lease terms then govern whether the improvement is approved, requires removal, or is otherwise addressed.

Question 144: What is the purpose of a ground fault circuit interrupter (GFCI)?

To protect against electrical shock (Correct answer)
To reduce fire risk
To improve voltage regulation
To prevent circuit overload

Correct answer: To protect against electrical shock

A Ground Fault Circuit Interrupter (GFCI) is a safety device designed to protect people from severe electrical shocks. It works by monitoring the electrical current flowing through a circuit and quickly cutting off power if it detects an imbalance, indicating that current is leaking to the ground—potentially through a person. This rapid response can prevent electrocution.

Question 145: What type of ventilation relies solely on natural forces such as temperature differences and wind pressure to move air, without any mechanical equipment?

Energy recovery ventilation
Exhaust-only ventilation
Mechanical ventilation
Natural ventilation (Correct answer)

Correct answer: Natural ventilation

Natural ventilation uses buoyancy (stack effect) and wind pressure differentials to move air through openings in the building envelope without any fans or powered equipment.

Question 146: A landlord retaliates against a tenant for reporting a habitability complaint to a local housing authority. Under most state laws, this action is:

Permissible if the landlord provides 30 days notice
Illegal under retaliatory eviction protections (Correct answer)

Correct answer: Directing buyers of a particular ethnicity only to homes in specific neighborhoods

Steering is the illegal practice of directing buyers or renters toward or away from neighborhoods based on protected class characteristics.

Question 148: Why should a home inspection report avoid specifying a single fixed repair cost rather than a range?

Fixed costs require a licensed contractor to verify before inclusion
Single figures are legally binding in most states
Single figures trigger mandatory escrow holdbacks by lenders
Contractor pricing varies; a range better reflects real-world cost uncertainty (Correct answer)

Correct answer: Contractor pricing varies; a range better reflects real-world cost uncertainty

Material and labor costs vary by contractor, timing, and region; providing a realistic cost range more accurately reflects actual market variability.

Question 149: An inspector finds that the main water shut-off valve is located but cannot be fully operated. What should be documented?

Report it only if the home is in a flood-prone area
Only the location of the valve needs to be noted
The valve is inaccessible or inoperable and should be serviced or replaced (Correct answer)
Nothing, as shut-off valves are rarely used

Correct answer: The valve is inaccessible or inoperable and should be serviced or replaced

A non-operable main shut-off valve is a safety deficiency because it cannot be used to stop water flow in an emergency.

Question 150: In building science and ventilation assessment, what does the abbreviation 'ACH' stand for?

Airflow Coefficient of Housing
Air Changes per Hour (Correct answer)
Attic Cooling Humidity rating
Air Conditioning Hours

Correct answer: Air Changes per Hour

Correct answer: The expansion tank may be waterlogged or failed

Consistently high pressure in a boiler system typically indicates a waterlogged or failed expansion tank, which can no longer absorb pressure fluctuations as water expands when heated.

Question 153: Which statistic should a home inspector monitor to evaluate the effectiveness of their Google Business Profile listing?

Number of posts made to the profile
Phone calls and direction requests generated from the listing (Correct answer)
Number of profile followers
The profile's color scheme and visual branding

Correct answer: Phone calls and direction requests generated from the listing

Phone calls and direction requests are direct action metrics showing how many potential clients are contacting the business as a result of the listing.

Question 154: When performing a rental property inspection, the inspector notices the tenant has installed an unauthorized pet door. What is the correct course of action?

Fine the tenant on the spot
Approve the modification since it is minor
Remove the pet door immediately
Document the modification and report it to the property owner (Correct answer)

Correct answer: Document the modification and report it to the property owner

Inspectors document unauthorized modifications and report them to the owner, who then follows lease terms to address the matter.

Question 155: A home inspector working for a lender is asked to produce a report that downplays defects in a neighborhood the lender considers 'undesirable.' The inspector should:

Note the issues privately but omit them from the report
Refuse and provide an honest, unbiased report (Correct answer)
Follow the lender's instructions to retain the client
Transfer the assignment to another inspector

Correct answer: Refuse and provide an honest, unbiased report

Inspectors must provide honest, unbiased reports regardless of client instructions; participating in redlining-type practices violates ethical and legal standards.

Question 156: A home inspector tests multiple faucets and finds low water pressure only at hot water fixtures. What is the most likely cause?

Faulty pressure regulator
Failing water heater dip tube (Correct answer)
Partially closed main shutoff
Clogged aerators on all fixtures
