Tucson Pool Fence Requirements

Arizona Law, the City Code and Pima County

The state rule is ARS 36-1681. It reaches any pool at least 18 inches deep and over 8 feet across and asks for a fence or wall 5 feet tall on the street side, no gap wide enough for a 4-inch sphere, gates that open away from the water and shut and latch on their own, no footholds on the outside, and a 20-inch buffer from the pool edge. If the house closes one side of the yard, the law wants an added layer there, such as a 4-foot inner fence or self-latching doors with locked-down windows. It carves out homes with no resident under 6 and defers to local ordinances that came first or that match or beat it.

City of Tucson. Tucson Code Section 6-191 adopts the International Swimming Pool and Spa Code (ISPSC), 2024 edition, with local amendments under Ordinance 12171, in effect January 1, 2026. The city amendments extend the barrier rule to water 18 inches or deeper and wider than 8 feet and require an evaporation cover on new and remodeled pools, but they do not change the ISPSC's 48-inch base height. The city's building code amendments apply ARS 36-1681 by reference to public and semipublic pools.

Unincorporated Pima County. The county building code adopts the 2024 ISPSC with county amendments (Pima County Code 15.04.020, Ordinance 2025-15), and the county lists the 2024 codes as in effect from January 1, 2026. The county's amendments to the 2024 ISPSC (Ordinance 2025-15, Exhibit J) change Section 305 in one place: the barrier rule in 305.2 also covers any other contained body of water that is 18 inches or deeper at any point, wider than 8 feet at any point, and intended for swimming. They leave the 48-inch height as the model code sets it. The county's barrier page still describes chapter 3 of the earlier 2018 ISPSC: a barrier at least 48 inches high, a bottom gap of no more than 2 inches, and self-closing, self-latching gates that open outward. It exempts spas with a lockable ASTM F1346 cover and pools with a powered ASTM F1346 cover.

Both local codes print 48 inches where the statute says 60. We have not found a published ruling on which number an inspector applies, so ask your permit office before you order a fence. A 60-inch barrier satisfies all three.

State enforcement is mild: a petty offense, dropped to no fine if the owner puts up a compliant barrier and sits through an approved safety course within 45 days of the ticket [ARS 36-1681(F)].

Pool Fence Cost in Tucson: National Ranges

We found no published source that prices pool fences by state or city, so these are national installed ranges from our pool fence cost guide. Quotes where you live can land above or below them.

National typical installed ranges, not quotes. Multiply by your fence perimeter. Some sources include one gate in the figure; extra gates, permits and hard deck surfaces add to the total.

Frequently Asked Questions

Tucson Pool Fencing: Check the Height First

Tucson runs on the same state statute as Phoenix, but both the City of Tucson and unincorporated Pima County publish codes that print 48 inches where the statute says 60. Which number your inspector uses depends on where you live, so ask before you order a fence; a 60-inch barrier clears all of them.

The house-wall rule is the other design decision to make early. Arizona allows the house to form part of the enclosure only with added protection, such as a separate 4-foot barrier or self-latching doors and restricted windows. The state penalty is a petty offense with no fine if you fix the barrier and take a safety course within 45 days; the real stakes are the permit inspection and the safety of young children.
