Full Breakdown
Doña Ana County's Building Code chapter (Chapter 142) controls all construction, alteration, and repair of buildings and structures, including swimming pools, within the unincorporated areas of the county under § 142-1. Section 142-3 folds the 2012 New Mexico Swimming Pool, Spa and Hot Tub Code directly into that chapter, so an in-ground or above-ground residential pool must meet the state plumbing and safety standards enforced through the county's building permit process, not just a zoning sign-off. 20-per-square-foot rate charged for new single-family and duplex construction.
Beyond the building permit itself, the Unified Development Code's general zoning rule at § 350-502B(11) governs pool placement and safety. An open, uncovered pool, hot tub, or spa may sit inside a required yard setback only if it stays at least five feet from the property line, a building, or a fence, and only if it is enclosed by an approved wall or fence at least four feet high with self-closing gate hardware. The Zoning Administrator may instead approve an automatic safety cover meeting the ASTM F1346 performance standard in place of that perimeter barrier.
Hot tubs and spas must carry an approved safety cover regardless. Because these are county rules, they reach only the unincorporated county; pools built inside Las Cruces, Sunland Park, Mesilla, or Hatch fall under each city's own adopted building and zoning code instead.
Violations & Fines
Building or occupying a pool without the required Building Code permit is enforced by the county's Building Official, who can red-tag construction and require it to stop until a permit is obtained and inspections pass. A pool that doesn't meet the § 350-502B(11) setback, barrier, or safety-cover standard is a zoning violation the Zoning Administrator may order corrected under Doña Ana County Code § 350-102B(2), which makes it unlawful to use land in violation of any provision of the Unified Development Code; owners who ignore a notice risk further code-enforcement action and fines set by the Board of County Commissioners.
