Arlington, TX Swimming Pools & Spas: Pool Permits (2026)

Arlington treats above-ground pools as regulated structures when they can hold water 24 inches or deeper, which includes most standard above-ground pools, inflatable pools, and soft-sided family pools from big-box retailers. A building permit is required, and applicants must submit a site plan showing setbacks, equipment locations, and barrier details. Setback requirements generally match those for in-ground pools, typically 5 feet from side and rear property lines, though exact distances depend on the zoning district. The pool wall itself may serve as the barrier if it is at least 48 inches high measured from grade on the exterior side and has no external handholds or footholds.

If the pool wall is shorter, a separate 48-inch barrier must enclose the pool area with a self-closing, self-latching gate. Ladders providing access to the pool must be removable, lockable, or surrounded by a barrier when the pool is not supervised. Electrical connections for pumps and filters must be GFCI-protected and installed per the National Electrical Code, with proper bonding of the pool structure and metal components. Pools are considered structures for property line setback purposes and count against impervious cover calculations. Temporary pools used for only a few days in summer and smaller than 24 inches deep are exempt, but any pool left filled across seasons is regulated. HOAs often prohibit above-ground pools outright, so check deed restrictions before purchasing.
