Teton County, WY Swimming Pools & Spas: Fencing Requirements (2026)

Teton County, Wyoming regulates swimming pool construction in the unincorporated areas through the Teton County Building Department under the County Building Codes Resolution adopted pursuant to Wyoming Statute Sections 35-9-101 through 35-9-121 and 18-5-201 through 18-5-207. The earlier resolution effective January 1, 2017 (amended June 5, 2018) adopted the 2015 IBC and 2015 IRC by reference, including specific listed appendices. The 2025 Building Code Resolution, passed and adopted on June 17, 2025 with an effective date of July 1, 2025, adopts the 2024 International Building Code and 2024 International Residential Code; per the Building Division, permits submitted on or after February 1, 2025 must use the 2024 IRC and IBC editions. Wyoming Statute 35-9-121 requires counties with local enforcement authority to adopt the statewide standards within six months of the state's adoption. The 2024 IRC contains residential pool-barrier requirements: a barrier must be at least 48 inches above grade measured on the outside; vertical clearance between grade and the bottom may not exceed 2 inches over a non-solid surface (4 inches over a solid surface); openings cannot allow passage of a 4-inch sphere; pedestrian access gates must be self-closing, self-latching, and open outward away from the pool. Teton County's adopted resolution does not contain custom pool-fence amendments above and beyond the IRC default. Wyoming has no statewide residential pool-fence statute. Public swimming pools (hotel, motel, apartment, public-use facilities) are regulated separately by the Wyoming Department of Agriculture under its administrative rules for public pools and spas, and Teton County operates a public-pool inspection program through its Environmental Health office. Teton County Building Department permitting fees are based on ICC Building Valuation Data with a county-set Permit Fee Multiplier; applications expire 180 days after filing absent good-faith pursuit (with up to two 180-day extensions). Contractors performing permitted work must hold a Town of Jackson contractor's license, except for owner-occupants performing work on their own primary residence (subject to limits in Section 117).
