Building Permits

In the areas of Bexar County that are outside of a municipality's limits, the Bexar County Fire Marshal Office (210-335-0300) determines when building permits are required for structures or areas that are not for a "single-family dwelling." use (Visit Fire Marshal Permits & Applications website).  A single-family dwelling is defined as a single structure consisting of 3 or less residential dwelling units. The building permit covers all of the following: site clearing, constructing, renovating or changing occupancy of a building.

BUILDING PERMIT AUTHORIZATION (BPA)

When a Building Permit is required by the Fire Marshal Office, a Building Permit Authorization is required to be completed by Public Works before a building permit is issued by the Fire Marshal Office. The Building Permit Authorization is the first page of the Building Permit form and is used to confirm that all the required County Public Works and Environmental Services permits as well as subdivision platting (if required) have been obtained/, completed, or in process.

For a short summary of the process, read the Building Guidelines (PDF).
