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

Hot tubs and spas in Denton fall under the pool enclosure requirements of Texas Health and Safety Code Chapter 757 if they are capable of holding water 18 inches or deeper. However, a listed safety cover that meets ASTM F1346 standards and remains locked when the spa is not in use may serve as an acceptable barrier in lieu of a separate fence. If the spa does not have a compliant locking cover, it must be enclosed by a 48-inch barrier with self-closing, self-latching gates identical to the pool fencing requirements.

The Denton Development Code requires an electrical permit for hot tub installations that involve new circuits. All hot tub electrical connections must be GFCI protected, and a disconnect switch must be located within line of sight of the spa but not less than 5 feet from the water edge per the National Electrical Code. Hot tubs must be set back from property lines according to the applicable residential zoning district setback standards. Portable plug-in hot tubs on existing dedicated circuits may not require a permit, but any hardwired 240-volt installation does.

Drainage from hot tubs must not flow onto neighboring properties or into the public right-of-way and should be directed to the sanitary sewer rather than the storm drain system.
