Do I need a permit for shed or accessory structure 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 may be required

It depends. Whether shed or accessory structure needs a permit in Bexar County (Unincorporated) comes down to the details of your project.

Many Texas cities exempt small accessory buildings. Dallas, for example, exempts a utility building under 200 square feet with no electrical, plumbing, or gas on single-family or duplex premises, but running utilities to a shed or exceeding the size threshold triggers a permit. Zoning setbacks and easement restrictions still apply even when a building permit is not required, so verify placement with your local building department.
