Hot tubs and spas in unincorporated San Diego County must meet the California Swimming Pool Safety Act requirements. Self-contained hot tubs with ASTM-compliant locking safety covers are exempt from barrier requirements. Permanently installed spas require building permits.
Hot tubs and spas are regulated under the same framework as swimming pools. Self-contained hot tubs or spas equipped with a locking safety cover that complies with ASTM standards are exempt from the fencing/barrier requirements that apply to pools. However, permanently installed spas and hot tubs require building permits including electrical and plumbing inspections. Spa covers must meet ASTM F 1346 standards for safety. Electrical installations must comply with the California Electrical Code, including GFCI protection. Hot tub equipment (pumps, jets) must comply with the County noise ordinance. Setback requirements from property lines apply per the zoning ordinance.
Unpermitted permanent spa installations may result in code enforcement action. Electrical safety violations pose fire and electrocution hazards and are treated seriously.
