Summary
Katy adopted the 2021 International Swimming Pool and Spa Code and 2021 IRC (effective Jan 1, 2024), which require a 48-inch barrier with self-closing/self-latching gates around residential pools; a permit is required for all in-ground and above-ground pools.
Sec. 757.003. ENCLOSURE FOR POOL YARD. (a) Except as otherwise provided by Section 757.005, the owner of a multiunit rental complex with a pool or a property owners association that owns, controls, or maintains a pool shall completely enclose the pool yard with a pool yard enclosure. (b) The height of the pool yard enclosure must be at least 48 inches as measured from the ground on the side away from the pool. (c) Openings under the pool yard enclosure may not allow a sphere four inches in diameter to pass under the pool yard enclosure. ... (f) The use of chain link fencing materials is prohibited entirely for a new pool yard enclosure that is constructed after January 1, 1994.
Full Breakdown
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.
Violations & Fines
Operating or filling a pool without an inspected and approved barrier triggers stop-work orders, failed inspections, and code enforcement citations from Katy Permits & Building Services (281-391-4830). Multifamily complexes and HOA-owned pools that fail Chapter 757 enclosure requirements face civil liability and state enforcement separately from city code.
