Iron County, UT Swimming Pools & Spas: Fencing & Safety Requirements (2026)

Section 17.36.160 requires that all swimming pools and pool areas be completely surrounded by a fence or wall with a minimum height of six feet, a barrier standard that applies countywide to any residential, commercial or shared pool in the unincorporated area. The rule sets a maximum opening size of thirty-six square inches for any gap in the fence or wall, meaning ornamental fencing with wide gaps between pickets or rails does not meet the standard unless the openings are kept smaller than that threshold.

Access gates through the pool barrier are singled out for extra hardware: every gate must be equipped with a self-closing device and a self-latching device so the barrier cannot be left open after someone passes through it. The section does not carve out an exception for above-ground pools, spas or hot tubs by size, so any structure that functions as a swimming pool on a residential lot is subject to the same six-foot fence, thirty-six-square-inch opening limit and self-closing gate rule. The requirement sits within Chapter 17.36, General Requirements and Property Development Standards, the same chapter that sets the county's setback, accessory-building and RV-storage rules for unincorporated Iron County, and it applies whether the pool is added by a homeowner or built as part of a new subdivision.

Iron County Planning and Zoning/Building and the building official check pool barriers as part of the building permit process for new pool construction, and a homeowner installing a pool without permit review risks a stop-work order until the fence meets the six-foot height and self-latching gate requirements.
