Summary

Hot tubs and spas in unincorporated Maricopa County are subject to ARS 36-1681 pool barrier requirements. All spas must have barriers or an approved safety cover. Spas not exceeding 8 feet wide may use a locking safety cover in lieu of full perimeter fencing if perimeter fencing already exists around the property.

Full Breakdown

Hot tubs and spas in unincorporated Maricopa County are subject to the same pool barrier requirements under ARS 36-1681 if they hold water 18 inches deep or more and are not equipped with a locking safety cover meeting ASTM F1346 standards. An approved safety cover can substitute for barrier fencing around a hot tub. Electrical work for hot tub installation requires a permit and must comply with the National Electrical Code, including GFCI protection and proper bonding. In Maricopa County's desert climate, water conservation considerations are important as evaporation rates are high, and covers are recommended both for safety compliance and to reduce water loss.
