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

Lewisville enforces pool barrier requirements through its building code and Texas Health and Safety Code Chapter 757. All residential pools capable of holding water 18 inches or deeper must be surrounded by a barrier at least 48 inches tall measured from the exterior side. Barriers must not have openings or gaps that would allow a sphere 4 inches in diameter to pass through. Chain-link fencing used as a pool barrier must have no larger than 1.25-inch diamond openings. Gates must be self-closing and self-latching, with the latch located at least 54 inches above grade or on the pool side with a release mechanism requiring reaching over the gate. Doors from the dwelling that open directly to the pool area must be equipped with an alarm or self-closing device. The property boundary fence may serve as part of the pool barrier if it meets height and construction standards. Above-ground pools with walls 48 inches or higher may use the pool wall as a barrier if the access ladder is removable or has a lockable gate. A building permit from the Lewisville Inspections Division is required before pool construction begins. The pool barrier must pass inspection before the pool is filled.
