Residential Building Inspector Practice Exam

Protection from decay is required for wood when it is used in which of the following locations?

1. For framing walls only

2. In areas exposed to water

3. In the locations indicated in section R317.1

4. In kitchens and bathrooms only

The correct answer is: In the locations indicated in section R317.1

The correct answer emphasizes the guidelines outlined in section R317.1 of the building code, which specifies the requirements for protecting wood from decay. This section covers a broad range of applications and locations, not limited to just areas exposed to moisture, but also includes situations where wood is in contact with the ground or subject to wet conditions, such as in basements and locations where wood is exposed to potential decay factors. The necessity for decay protection arises from the fact that wood is an organic material that can be harmed by moisture, fungi, and insects, which can compromise the structural integrity of a building. R317.1 establishes standards for selecting appropriate materials and methods to prevent such damage, which is critical for ensuring long-lasting structural performance. Other choices may represent more limited scenarios for wood decay without the comprehensive scope provided in section R317.1. While areas exposed to water and places like kitchens and bathrooms certainly warrant decay protection, the correct answer captures the full range of required locations for wood protection, providing necessary guidance for various construction circumstances.
