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

Lewisville building department requires a building permit before constructing, installing, or substantially modifying a residential swimming pool, spa, or hot tub. The permit application requires a site plan showing the pool location relative to property lines, structures, easements, and underground utilities. Minimum setbacks from property lines apply per zoning district requirements. All residential pools must be enclosed by a barrier (fence, wall, or combination) at least 48 inches in height with self-closing, self-latching gates per the International Residential Code Section R326 (Pool and Spa Enclosures). Gates must open outward away from the pool and latch at least 54 inches above grade. The barrier must not have openings that allow passage of a 4-inch sphere. Electrical installations for pool equipment (pumps, heaters, lighting) require a separate electrical permit and must comply with NEC Article 680 (Swimming Pools, Fountains, and Similar Installations) including GFCI protection and bonding requirements. The city conducts inspections at multiple stages: excavation, steel/rebar, plumbing rough-in, electrical rough-in, barrier, and final. Above-ground pools exceeding 24 inches in water depth also require a permit and barrier. Pool drains must comply with the Virginia Graeme Baker Pool and Spa Safety Act (federal) for anti-entrapment. Permit fees are based on project valuation.
