Full Breakdown
Mohave County permits a permanent spa or hot tub primarily for its 240-volt electrical circuit and GFCI-protected bonding under the 2018 IRC adopted in Building Ordinance 2021-03. Arizona's §36-1681 barrier law defines a regulated pool as a contained body of water 18 inches or more deep and wider than eight feet, so a typical hot tub narrower than eight feet is not caught by the five-foot barrier requirement. A spa built into a larger pool, or one over eight feet wide, does fall under the barrier rules. A locking, rigid safety cover is still strongly advised. A deck supporting a filled spa may need structural verification for the added load.
Violations & Fines
Wiring a spa without an electrical permit, or discharging spa water onto a neighbor's property or into a storm drain, is a code violation requiring correction.
