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

Residential swimming pool construction in Bexar County requires multiple approvals. Inside the City of San Antonio, a building permit is required from the Development Services Department before excavation under Chapter 10 of the Code of Ordinances and the adopted 2021 International Residential Code. Fees begin at approximately 180 dollars for pools under 500 square feet with additional fees for electrical and plumbing sub-permits. The permit application requires a site plan showing setbacks (minimum 5 feet from side and rear property lines), a fencing plan, and equipment locations. Inspections occur at pre-gunite, deck, bond, and final stages. In unincorporated Bexar County, the Texas Local Government Code Section 233.033 authorizes counties to adopt the International Residential Code in unincorporated areas, and Bexar County has adopted building standards including pool permits through Commissioners Court orders. The county charges a flat residential pool fee and requires a permit through Public Works. All pools countywide must comply with Texas Health and Safety Code Chapter 757 pool yard enclosure rules and the federal Virginia Graeme Baker Pool and Spa Safety Act for drain cover standards. Pools on on-site sewage facilities need additional setback approval from Bexar County Environmental Services.
