Cobb County requires electrical permits for hot tub and spa installations. GFCI protection mandatory on 240V circuits. Barrier rules apply unless ASTM F1346 locking safety cover installed.
Cobb County requires an electrical permit through Cobb Community Development for residential hot tub and spa installations. The 240V circuit must have GFCI protection (or equivalent GFPE on larger units) and proper bonding of metallic parts per NEC Article 680. Disconnect must be within sight of the spa but at least 5 feet from the water. Zoning setback requirements apply — hot tubs typically treated as accessory structures requiring minimum side and rear yard setbacks (commonly 5 to 10 feet depending on zoning district). Barrier requirements under IRC Appendix G apply to spas with water depth over 24 inches, but an ASTM F1346-listed lockable safety cover satisfies the barrier requirement and is the common solution for residential hot tubs. Drainage from spa cannot discharge onto neighboring property or directly into storm drains — dechlorination before discharge recommended. Indoor spas require ventilation per IMC. Structural loading for deck-mounted spas should be verified (filled spa weighs 3,000 to 5,000 lbs).
Unpermitted electrical work: stop-work, double permit fees, required inspection. Missing GFCI or bonding: correction required before use. Drainage violations: remediation plan required. No safety cover without barrier: immediate compliance required.
