California Residential Inspector Practice Exam

What is the maximum floor area of a one-story detached accessory structure that does not require a permit to construct?

1. 100 square feet

2. 120 square feet

3. 150 square feet

4. 200 square feet

The correct answer is: 120 square feet

In California, regulations for detached accessory structures have specific guidelines regarding their size before requiring a permit for construction. The threshold that allows a one-story detached accessory structure to be constructed without a permit is 120 square feet. This limit permits homeowners to build small structures, such as storage sheds or playhouses, without going through the usual permitting process, which can save time and resources. When the area exceeds 120 square feet, a permit becomes necessary, as it indicates a more significant structure, potentially affecting property lines, zoning regulations, or building codes. The specification of 120 square feet is a common standard in many jurisdictions, aligning with the intent to allow minor improvements while still maintaining oversight over larger constructions.
