Bexar County, TX Swimming Pools & Spas: Fencing Requirements (2026)

Per Bexar County's Code Enforcement office, the County does not have legal authority to regulate single-family residential construction in unincorporated areas; permits are required only for commercial, public-accessible, multi-family residential, pre-built relocations, and substantial improvements to existing buildings (Texas Local Government Code §§233.061–233.067). Single-family pool fencing is therefore not enforced at the county level outside city limits. State-level Texas Health & Safety Code Chapter 757 requires a pool-yard enclosure of at least 48 inches in height, openings small enough that a 4-inch sphere cannot pass under or through, vertical-member spacing tightening to 1-3/4 inches when horizontal members are less than 45 inches apart, decorative cutouts no larger than 1-3/4 inches, and prohibits chain-link material for enclosures built after January 1, 1994 — but §757.002 expressly limits these requirements to multiunit rental complex pools and property-owners-association pools. Inside the City of San Antonio, municipal building code (adopted IRC/IBC) imposes the standard 48-inch barrier with self-closing/self-latching gates on residential pools deeper than 24 inches. Homeowners with HOA pools should confirm their HOA's compliance with Chapter 757.
