Do I need a permit for water heater replacement in Harris County (Unincorporated)?
Yes. In Texas, water heater replacement generally requires a permit, and Harris County (Unincorporated) is no exception.
Replacing a water heater requires a plumbing permit in most Texas cities, even for a like-for-like swap, and many offer express same-day permits. Switching fuel type, moving the unit, or converting to tankless can trigger additional gas, electrical, and venting work. Confirm the scope with your local building department. In Harris County, permits outside the cities are handled by the Harris County Office of the County Engineer - Permits, reachable on 713-274-3900 at https://oce.harriscountytx.gov/Services/Permits. Its online permit portal is https://epermits.harriscountytx.gov. This office covers the unincorporated parts of Harris County. Texas counties differ widely in how much residential work they permit, and many do not issue residential building permits at all, so confirm what your specific project needs. If your address sits inside a city, that city issues the permit instead. Ask whether a like-for-like swap is exempt at your address, since that answer varies between the county and its municipalities.
