Summary: The Seattle Building Code (SBC) requires permits for temporary structures like tents, reviewing stands, temporary office trailers, scaffolding structures, construction buildings, and similar portable or collapsible structures. Temporary structure permits must meet code requirements for fire, life safety, and structural elements (SBC Section 106.10). Haunted houses and many other events also require a temporary certificate of occupancy (TCO) permit. For details, see Tip 120, Getting a Certificate of Occupancy. In addition, a temporary use permit may be required for temporary structures or events. If planning on using a temporary structure for more than four weeks, read Tip 206, Temporary Use Permits in Seattle.
