Tuscaloosa, AL Swimming Pools & Spas: Hot Tub Rules (2026)

Tuscaloosa does not have a separate hot-tub or spa ordinance. Whether a spa is treated as a 'swimming pool' under the Zoning Ordinance depends on size: the ordinance defines a swimming pool as a self-contained body of water at least 18 inches deep and eight feet in diameter or width. A typical residential hot tub narrower than eight feet does not meet that definition, so the zoning ordinance's six-foot enclosure rule in Sec. 25-107.x generally does not apply to it; a large spa meeting the 18-inch/8-foot threshold would be regulated as a pool. For the smaller spas and hot tubs, the controlling rules come from the construction codes Tuscaloosa has adopted, principally the 2021 International Residential Code. Under the model IRC pool/spa barrier provisions, where a spa or hot tub is equipped with a lockable safety cover listed and labeled to ASTM F1346, the area around it is not required to comply with the full barrier requirements; otherwise the standard 48-inch barrier rules apply. Electrical installation (bonding, grounding, GFCI protection) is enforced under the 2020 National Electrical Code, and a building/electrical permit is generally required for the spa's wiring and any structure over the permit threshold. Owners should confirm with Building and Inspections whether their specific unit needs a barrier or qualifies for the safety-cover exception.
