How far does a pool have to be from the property line in Southern Arizona?
Verified against the primary source on .
Between 4 and 15 feet depending on the jurisdiction, and the more important difference is WHAT the distance is measured to. Cochise County measures 7 feet to the EDGE OF THE POOL. Sahuarita measures 4 feet to the EDGE OF WATER. Santa Cruz County requires 7.5 or 15 feet and applies it to the pool AND all accessory equipment, side and rear only.
Two designs that are both 5 feet off the line can be measured to two different things and only one of them passes. The number is the easy part. The datum is what fails plan review.
The verified figures, side and rear, with the datum each jurisdiction actually uses:
Pima County, unincorporated: 4 feet, per Pima County Zoning 18.07.030(D)(1)(a). Front yard is the front yard requirement of the zone.
Sahuarita: 4 feet from the side or rear property line to the EDGE OF WATER, per the Town’s pool and spa permit submittal checklist. The checklist also requires the barrier in place before a fiberglass shell is set.
Sierra Vista: 4 feet to any lot line, and no pool in any required front or side yard, per UDO 151.04.009(A). The code regulates the pool with no structure-versus-water distinction drawn.
Benson: 5 feet to any lot line, and no pool in any minimum required front or side yard, per Zoning Regulations Section Twelve, Supplemental Regulations, Swimming Pools.
Cochise County, unincorporated: 7 feet, measured to the EDGE OF THE SWIMMING POOL, not to the water. Zoning Regulations Section 2.51.140, legacy Section 1816. Pools may be allowed in the side or rear setback area on that basis. It does not reach the front. The general RU district setback is 20 feet at Section 2.15.040.
Santa Cruz County, unincorporated, including Rio Rico and Tubac: 7.5 feet in R-1 through R-5, MF, MH and MFR; 15 feet in GR-40, GR, SR, B-1, B-2 and M-1. Zoning and Development Code Section 1600. Two things make this the strictest in the region: the setback applies to the contained body of water AND ALL ACCESSORY EQUIPMENT, so the pad counts; and siting is restricted to the side and/or rear yard only, with any front-yard location requiring Board of Adjustment approval.
Oro Valley: 5 feet rear for an in-ground pool or spa, 3 feet rear for an aboveground spa, with front AND side setbacks taken from the zone, per Zoning Code 25.2.F. Where Environmentally Sensitive Open Space is mapped, pools take 20 feet under 27.10.F.3.b, reducible to no less than 5 feet at the Planning and Zoning Administrator’s discretion, and the more restrictive setback wins. On a PAD lot the PAD text overrides the base district.
Marana: no pool setback is published at all. That is a finding, not a gap, and it has its own record.
Tucson, South Tucson and Pinal County: not closed. Tucson’s codified table and its own PDSD summary sheet conflict and neither names a pool. Pinal County’s zoning code contains the word pool zero times outside a lot-coverage carve-out. Do not design to a number in these three without a written answer from the jurisdiction.

Correction. Summaries that give a single Southern Arizona pool setback figure, and those that assume the measurement is always taken to the pool structure.
Important. Setbacks for Tucson, South Tucson and Pinal County are open items in the system of record and are deliberately not given a number here.
