Do I need a permit for a pool or hot tub?

Short answer: Across the 25 US cities we checked, a pool or hot tub always needs a permit in 13, needs none in 0, and depends on size, location or scope in 10; 2 are unverified. Your city's rule is what counts.

Many cities adopt the International Residential Code exemption for small prefabricated pools (under 24 in deep, installed above ground); in-ground pools and spas usually need building, electrical and barrier (fence) approvals.

General pattern only, not a rule for any city. The table below is built from each city's official source.
