Swimming Pools & Spas in Tempe, AZ: What Residents Actually Need to Know
If you live in Tempe or are thinking about moving there, swimming pools & spas are one of those things you probably won't think about until they affect you directly. Tempe has 5 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.
Pool Permits
Tempe requires building permits for pools, spas, and hot tubs. Arizona has strict pool barrier requirements under ARS §36-1681. Inspections required.
Key details: Permit: Required for all pools. Above-Ground: If >24" deep. Barriers: ARS §36-1681. Inspections: Electrical, barrier, final.
Unpermitted pool: stop-work order. Retroactive permit with penalty fees. Non-compliant barriers: immediate correction required.
Safety Rules
Tempe enforces pool safety regulations including barrier requirements, drain covers, and maintenance standards. Pools must be maintained to prevent becoming health hazards or mosquito breeding grounds. Arizona law also requires pool safety notices.
Key details: Drain Covers: VGB Act compliant required. Maintenance: Must prevent mosquito breeding. Safety Posting: CPR instructions required. Abandoned Pools: Must be drained and secured.
Pools not meeting safety standards may result in code enforcement action. Unmaintained pools creating health hazards may be declared a nuisance. The city can require draining and securing of abandoned pools at the owner's expense.
This is one of the stricter rules in Tempe's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
Fencing Requirements
Tempe requires all residential swimming pools to be enclosed by a barrier at least 5 feet high with self-closing, self-latching gates. This applies to in-ground and above-ground pools, spas, and hot tubs containing water deeper than 18 inches.
Key details: Barrier Height: 5 feet minimum. Gate: Self-closing, self-latching. Latch Height: 54 inches above grade. Opening Size: No gaps larger than 4 inches. Door Alarm: Required for house-to-pool doors.
Non-compliant pool barriers are a serious safety violation. The city may issue immediate correction notices and can impose daily fines until compliance is achieved. Drowning incidents may result in criminal liability for the property owner.
Compared to other cities, Tempe takes a harder line on fencing requirements. The enforcement and penalty structure reflects that.
Above-Ground Pools
Above-ground pools in Tempe must meet the same barrier requirements as in-ground pools if they hold water deeper than 18 inches. The pool walls may serve as part of the barrier if they meet height requirements and ladders are removable or lockable.
Key details: Depth Threshold: 18 inches triggers barrier requirements. Wall as Barrier: Allowed if 5+ feet with no footholds. Ladder: Must be removable or lockable. Exempt: Temporary pools under 18 inches deep.

Hot Tub Rules
Hot tubs and spas in Tempe are regulated under the swimming pool code and ARS 36-1681. Spas with water over 18 inches deep require barrier protection. Electrical installations need a permit with GFCI protection. Lockable ASTM-compliant safety covers can serve as an alternative to barrier enclosure. Given Tempe's climate, hot tubs are popular year-round.
