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

The City of Katy adopted the 2021 International Building Codes (including the 2021 International Residential Code and 2021 International Swimming Pool and Spa Code) and the 2023 National Electrical Code, effective January 1, 2024, codified in the Code of Ordinances Chapter 3 (Building Regulations). Residential pool barriers follow IRC Appendix AG105 / ISPSC standards: enclosure at least 48 inches high measured on the side facing away from the pool, no openings allowing passage of a 4-inch sphere, no climbable horizontal members on the outside, and gates that are self-closing, self-latching, and open outward away from the pool with the latch at least 54 inches above the ground. A building permit is required from the Permits & Building Services department for every new in-ground and above-ground swimming pool. Texas Health and Safety Code Chapter 757 imposes additional pool-yard enclosure requirements specifically on multiunit rental complexes and property owners associations (not single-family homes), including 48-inch enclosure height and 4-inch maximum opening; for single-family homes the IRC/ISPSC barrier rules adopted by Katy are the controlling standard.
