Permit & code requirements in San Antonio

The City of San Antonio Development Services Department handles permits for permanent backup generator work through its online permit system, and only a license professional registered with the city can pull an electrical permit. Confirm requirements for the exact address before installation.

In San Antonio's online permit system, Development Services tells applicants to file a whole home generator under the Solar-Photovoltaic permit type.
