California Residential Inspector Practice Exam

What is the maximum clear span for floors in buildings constructed according to the California Residential Code?

1. 30 feet

2. 32 feet

3. 35 feet

4. 38 feet

The correct answer is: 32 feet

The maximum clear span for floors in buildings constructed according to the California Residential Code is indeed 32 feet. This limit is set to ensure structural integrity and safety, facilitating the adequate distribution of loads across the framing system. A clear span refers to the unobstructed distance between two supports. In residential construction, maintaining appropriate spans protects against excessive deflection and vibration that could lead to structural issues over time. The code specifications take into account various factors such as material strength, use of the space, and design loads, which all contribute to this span limitation. By adhering to this maximum clear span, builders can assure that the floor systems provide the necessary support and stability for residential structures.
