Bernalillo County, NM Swimming Pools & Spas: Hot Tub Rules (2026)

Installing a residential hot tub or spa in New Mexico requires an electrical permit for the 240V/50A circuit (some plug-and-play 120V units are permit-exempt) from Albuquerque Planning or the NM CID for unincorporated Bernalillo County. The installation must comply with NEC Article 680 as adopted by NM CID: GFCI protection, equipotential bonding, and proper receptacle distance (5-10 feet from the tub wall). IRC Appendix G as amended by NM allows an ASTM F1346-compliant lockable safety cover to substitute for a perimeter barrier around a spa or hot tub; without the cover, a 48-inch barrier with self-closing gates is required. Setbacks generally match accessory structure requirements (5 feet side/rear in R-1 zones). Drainage from chemically-treated water may not discharge to storm drains or neighboring properties under the Clean Water Act and ABQ's MS4 permit; dechlorinated draining to landscaped areas or sanitary sewer cleanouts is acceptable. Indoor spas need mechanical ventilation per IMC §403. Structural review is required for hot tubs on elevated decks (typical loaded weight 3,000-5,000 lbs).
