Do I need a permit for window or exterior door replacement in Harris County (Unincorporated)?
Most likely yes. Window or exterior door replacement usually requires a permit in Texas. Confirm the specifics with Harris County (Unincorporated).
Straight like-for-like window and door replacements are exempt in some Texas cities (Austin, for example, exempts garage door replacements), but enlarging an opening, changing egress, or altering structure typically triggers a permit and a framing inspection. Requirements vary by city and are set locally under Texas Local Government Code Ch. 214, not by the state. Confirm the exact rules with your local building department. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule. 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 changing the size of an opening is structural work and is treated differently.
