Permit Technician Practice Test

During which inspection is vapor barrier placement typically assessed?

1. Final inspection

2. Footing inspection

3. Rough-in inspection

4. Framing inspection

The correct answer is: Footing inspection

Vapor barrier placement is typically assessed during the footing inspection. This inspection occurs prior to the pouring of concrete and is crucial for ensuring that the foundation is properly set up to prevent moisture intrusion. During the footing inspection, the inspector checks to see that the vapor barrier, which acts as a protective layer against moisture from the ground, is correctly installed underneath the footings and walls. This inspection is vital because effective moisture control is essential for the longevity of the structure and to prevent complications such as mold or wood rot, which can arise from dampness. The placement of the vapor barrier at this stage helps establish a critical line of defense against ground moisture entering the building envelope. In contrast, the other inspections focus on different structural elements or stages of construction. For example, the final inspection involves checking the completed construction for compliance with building codes, and the rough-in inspection addresses plumbing and electrical work before walls are closed up. The framing inspection is concerned with the structural integrity and alignment of the framing components, rather than moisture considerations. Therefore, the footing inspection is the specific phase where the assessment of vapor barrier placement is most relevant.
