What is the required pool barrier height in the City of Tucson?
Verified against the primary source on .
60 inches. Tucson’s own code states no pool barrier height, and its adoption post-dates the state statute, so A.R.S. 36-1681 applies directly and sets five feet measured on the exterior side.
Tucson Code Sec. 6-191 adopts the 2024 ISPSC by Ordinance 12171 Sec. 8, adopted June 3, 2025, effective January 1, 2026. The prior adoption was the 2018 ISPSC by Ordinance 11590 Sec. 9, effective January 1, 2019.
Tucson Code Chapter 6, Article IX, the Swimming Pool and Spa Code, was read in full. It contains three sections and none of them states a barrier height. The only pool text in the adopting ordinance is Ordinance 12171 Exhibit G, which revises ISPSC 305.2 and 304 and carries no height figure. Tucson did amend 305.2, expanding scope to any contained body of water 18 inches deep and more than 8 feet wide, and 305.4, on a structure wall serving as a barrier. It did not touch the height.
That leaves the state statute, and the statute reaches Tucson. A.R.S. 36-1681(B)(1) requires a barrier of at least five feet measured on the exterior side. Subsection (D)(6) exempts a political subdivision that adopted its own barrier ordinance after the article took effect on June 1, 1991, but only where that ordinance is equal to or more stringent than the statute. Tucson’s adoption is effective January 1, 2026, so (D)(6) is the operative test, and the 48 inch ISPSC base height is less stringent than five feet and cannot satisfy it. Subsection (D)(5), which exempts pre-1991 barrier ordinances with no stringency test at all, is unavailable on the codified record: Article IX dates only to Ordinance 11590 in October 2018.
Design and build to 60 inches in the City of Tucson, measured on the side of the barrier facing away from the pool, maintained around the entire perimeter and for 3 feet measured horizontally from the outside of the barrier.
How the height is measured. The dimension is taken on the side of the barrier facing AWAY from the pool, not the pool side, and it must be maintained around the entire perimeter and for 3 feet measured horizontally out from the outside face. A barrier that meets the height at the gate and loses it where grade falls away does not comply. Grade changes on a sloped Southern Arizona lot are the usual reason a wall that measured correctly at layout fails at inspection.
Crossing a jurisdiction line changes this number. City of Tucson requires 60 inches. Also at 60 inches: Town of Marana, Town of Oro Valley, Town of Sahuarita. Different in the same metro area: unincorporated Pima County at 48 inches. A builder working across Southern Arizona cannot carry one standard barrier detail, and a barrier specified for one town will fail inspection in another.
Verified against the jurisdiction’s own adopted text on 2026-09-10: in City of Tucson, the gate latch release sits not less than 54 inches above grade; the barrier stands at least 20 inches back from the water’s edge; horizontal members on the outside face are spaced not less than 45 inches apart vertically; no opening passes a 4 inch sphere; chain link mesh is limited to 1.75 inches.
Correction. An earlier version of this record stated 48 inches, reasoning that Tucson did not amend ISPSC 305.2.1 so the code base governed. That reasoning read the local code and never ran the A.R.S. 36-1681(D)(6) stringency test against it. Corrected on 2026-09-15 after a primary-source audit of Tucson Code Ch. 6 Art. IX and Ord. 12171 Exh. G.
Important. One open item, and it does not change the answer. Whether a superseded pre-1991 Tucson pool enclosure ordinance existed under some other section number cannot be settled from the online code, because American Legal Publishing does not retain repealed predecessor sections. Only the City Clerk’s ordinance index can close it. The City neither publishes nor enforces 48 inches, so 60 is the correct published answer either way.
Authority: Tucson Code Sec. 6-191; Ord. 12171 Exh. G. Ordinance: Ord. 12171 Sec. 8. Effective: 2026-01-01. Verified 2026-09-10. Primary source. Evidence grade: VERIFIED. Read from the adopting ordinance or the published code section.
