What is the minimum size of temporary structures that require a permit from the building official?

The minimum size of temporary structures that require a permit from the building official is generally specified in building codes, which vary by jurisdiction. In many cases, a threshold of 120 square feet is established as the point at which a temporary structure must have a permit. This size considers safety, zoning, and possible impacts on surrounding areas.

Structures below this size may not pose significant risks or impacts that warrant oversight, making the permitting process more straightforward for small, temporary constructions. However, when a structure exceeds 120 square feet, the local building authority typically requires a permit to ensure compliance with safety standards and regulations. This helps to mitigate issues such as structural integrity, fire safety, and intrusion on public space. Knowing this guideline is essential for compliance as a construction supervisor.
