Hot tubs and spas in San Diego are regulated under the same framework as swimming pools per CBC Section 3109, the International Swimming Pool and Spa Code, and SDMC Chapter 14, Article 5, Division 31. Building permits are required for permanent spa installations. Hot tubs with locking safety covers that comply with ASTM F1346 may satisfy the barrier requirement. Electrical work must comply with the California Electrical Code.
San Diego requires permits for hot tub and spa installations primarily for the electrical connection (240V circuit). Hot tubs must meet setback requirements from property lines. Barrier requirements apply when the hot tub is accessible to children, though a locking safety cover may satisfy this in some jurisdictions. Drainage must not discharge onto neighboring properties or into storm drains. Weight considerations may require structural assessment for deck or elevated installations. Indoor spas may require additional ventilation. GFCI electrical protection is mandatory.
Unpermitted electrical work: fines and required correction. Drainage violations: remediation required. Safety cover violations: immediate correction.
