Do I need a permit for a water heater replacement in San Antonio, TX?

Last verified: · Confidence: high · Status: Verified from official source

Not legal advice. Always confirm with your local building department. Rules change, and your parcel's zoning, HOA, historic district, floodplain or utility work can change the answer. We show the official source and the date we last checked it so you can verify for yourself.
Permit required Confidence: high

Yes. Installing or replacing a water heater needs a plumbing permit. A Limited Service Repair permit lets urgent water heater repairs be filed within 3 days.

What changes the answer

Note: Two official documents list different plumbing base fees.

Cost

Base fee plus a per-fixture charge. The FAQ says $50 plus per-fixture costs, but the current plumbing application lists a $57.50 inspection fee plus $9.20 for a water heater. Unverified, confirm locally. Unverified, confirm locally
