What does it mean when a building is called a temporary structure?
NationwideReviewed October 2026
In the International Building Code, a temporary structure is one erected for 180 days or less. The building official may issue a permit for such a structure, and it must still meet requirements for structural strength, fire safety, exits, accessibility, light, ventilation and sanitation. The 2024 IBC lets certain public-occupancy temporary structures be extended up to a year with extra inspections and an engineer's review. Calling something temporary does not exempt it from permits; the ICC notes permits and construction documents are typically required. A structure kept beyond the allowed period generally must meet the rules for permanent buildings. Your local code and zoning define how this works where you live.
Check your local rule. This varies by state, county or city. Your permitting office has the final word; the official lookup pages below show you who that is.
