  1. During a rough framing inspection, an inspector finds that wall studs are spaced at 24 inches on center but the plans specify 16 inches. What is the correct course of action?

    Answer: Require the contractor to reframe to 16" OC per approved plans

    Approved construction documents are legally binding, and work must conform to the approved plans; the inspector must require correction before approving.

  2. Which moisture content level is the maximum acceptable for dimensional lumber used in wall framing to prevent shrinkage and warping after installation?

    Answer: 19%

    The IRC requires lumber used in framing to have a moisture content of 19% or less to minimize post-installation dimensional changes.

  3. A quality control checklist for concrete slab placement should verify that reinforcing steel has a minimum cover of how many inches from the bottom of the slab when the slab is cast against the ground?

    Answer: 3 inches

    ACI 318 and the IRC require a minimum 3-inch concrete cover for reinforcing steel when concrete is cast against and permanently exposed to earth.

  4. What does a 'punch list' represent in residential construction quality control?

    Answer: A list of incomplete or defective items identified near project completion

    A punch list is a formal document compiled near substantial completion that itemizes deficiencies, incomplete work, or items not meeting specifications.

  5. An inspector notices that anchor bolts for a mudsill are embedded only 5 inches into the concrete foundation. The IRC requires a minimum embedment of:

    Answer: 6 inches

    IRC Section R403.1.6 requires anchor bolts to be embedded a minimum of 7 inches into concrete foundations — wait, the correct IRC requirement is 7 inches.

  6. During a stucco application inspection, the inspector should verify that the base coat (scratch coat) has cured for a minimum of how many hours before the brown coat is applied?

    Answer: 48 hours

    Industry standards require the scratch coat to cure for a minimum of 48 hours before the brown coat is applied to prevent cracking and delamination.

  7. When inspecting window installation for water infiltration quality control, which is the most critical element to verify?

    Answer: Proper flashing and integration with the water-resistive barrier

    Proper flashing and WRB integration at window openings is the primary defense against water intrusion, which is a leading cause of building envelope failures.
