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: medium

Yes. Most plumbing work needs a permit; only fixture or valve repairs and replacements without piping changes are exempt, and a water heater is an appliance, not a fixture.

Note: Water heaters are not named on the exemption list; confirm with the Permits Division.
