Residential Building Inspector Practice Exam

For a one-story detached accessory structure, a permit is not required if the maximum floor area does not exceed how many square feet?

1. 150 square feet

2. 200 square feet

3. 250 square feet

4. 300 square feet

The correct answer is: 200 square feet

In many jurisdictions, building codes specify that certain types of smaller structures, such as one-story detached accessory structures (often including sheds and similar buildings), may not require a permit if they remain below a specified floor area threshold. This threshold is often set at 200 square feet. Staying within this size limit generally simplifies the process, as homeowners can construct these structures without needing to go through the longer permitting process associated with larger builds. The rationale behind these regulations is likely tied to the idea that smaller structures pose less risk from a safety and zoning perspective, as they are less likely to impact neighboring properties significantly nor require comprehensive inspections and planning. If a structure exceeds this floor space limit, then the jurisdiction typically requires a permit to ensure compliance with safety codes, zoning regulations, and property lines. Thus, the choice indicating 200 square feet aligns with common municipal codes, making it the correct answer in this context.
