Do I need a permit for window or exterior door replacement in Bexar County (Unincorporated)?

Bexar County (Unincorporated) does not issue residential building permits. In the areas of Bexar County outside a municipality's limits, the county does not issue building permits for single-family dwellings. Bexar County defines a single-family dwelling as a single structure consisting of three or fewer residential dwelling units. The Bexar County Fire Marshal's Office, 210-335-0300, determines when building permits are required for structures that are not single-family dwellings. Separate approvals such as on-site sewage facilities, floodplain development and driveway access are handled by other offices and still apply.

The requirements below come from Texas rules and describe the standard the work must still meet. They are not a statement that Bexar County (Unincorporated) will issue you a permit.

Permit likely required

Most likely yes. Window or exterior door replacement usually requires a permit in Texas. Confirm the specifics with Bexar 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.
