California Residential Inspector Practice Exam

What are the minimum dimensions required for the rough-framed opening for attic access in buildings with combustible roof construction?

1. 18 inches by 24 inches

2. 22 inches by 30 inches

3. 24 inches by 36 inches

4. 30 inches by 36 inches

The correct answer is: 22 inches by 30 inches

The minimum dimensions required for the rough-framed opening for attic access in buildings with combustible roof construction is established to ensure safe and practical access to the attic space for maintenance, inspection, or repairs. The specified dimensions of 22 inches by 30 inches provide adequate space for individuals to enter and maneuver within the attic area comfortably and safely, while also allowing for the transport of tools and materials needed for work in that space. These dimensions help to comply with safety standards and building codes, which recognize the necessity for workers or residents to have sufficient room not only to access the attic but also to navigate around any obstructions that might be encountered once inside. Adhering to these minimum requirements also minimizes the risk of injury when using the access point. Larger dimensions, while potentially more convenient, are not a requirement according to the code, so they are not considered correct in this context. The chosen dimensions reflect a balance between safety, accessibility, and the practicalities of construction standards.
