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

Flower Mound Building Inspections requires a building permit for all new swimming pool, spa, and hot tub installations on residential and commercial property. The permit application must include a site plan showing the pool location relative to property lines, structures, easements, and utility lines; a barrier and fencing plan meeting ISPSC and town requirements; electrical plans for pool pumps, lighting, and any bonding/grounding; and plumbing plans for drainage and fill connections. Pool barriers must be at least 48 inches tall measured on the exterior side, non-climbable (chain link is prohibited for new pool enclosures under Texas building code adoption), and equipped with self-closing, self-latching gates that open outward from the pool area. The gate latch must be located at least 54 inches above grade or be otherwise inaccessible to small children. Required inspections include footer/steel, pre-plaster or pre-liner, electrical bonding, barrier, and final. Pool setbacks from property lines and structures vary by zoning district. Flower Mound requires pools to be connected to the sanitary sewer for backwash discharge rather than draining to the storm system. Pool demolition also requires a permit to ensure proper backfill, compaction, and utility disconnection. Portable above-ground pools and inflatable pools that hold more than 24 inches of water may also trigger barrier requirements.
