Summit County, CO Swimming Pools & Spas: Fencing Requirements (2026)

Summit County's Community Development Department, Building Inspection Division, enforces the 2018 family of I-Codes (including the IRC pool barrier provisions and the ISPSC) and the 2023 National Electrical Code, with local amendments. Under ISPSC Section 305 (and parallel IRC Appendix provisions), residential outdoor pool and spa barriers must be at least 48 inches above finished grade, measured on the side of the barrier facing away from the pool. Openings in the barrier cannot allow passage of a 4-inch sphere, and horizontal members on the pool side that are less than 45 inches apart must be on the pool side with maximum 1.75-inch spacing between vertical members. Gates that are part of the barrier must open outward away from the pool and be both self-closing and self-latching; the latch release must be at least 54 inches above the bottom of the gate, or located on the pool side at least 3 inches below the top of the gate. Where a wall of a dwelling forms part of the barrier, doors with direct access to the pool must be equipped with an audible alarm or other approved means of protection. Public, semi-public, and HOA pools in Summit County are also regulated by the Colorado Department of Public Health and Environment under 5 CCR 1003-5 (Swimming Pools and Mineral Baths), which requires a fence at least 60 inches high with self-closing, self-latching gates having a latch at least 54 inches high, wrought-iron picket spacing not greater than 4 inches, and a separate 3-foot enclosure for wading pools. A building permit is required from Summit County for pools, spas, and hot tubs, and barriers are verified at final inspection.
