Do I need a permit for standby generator installation in Katy?
Yes. In Texas, standby generator installation generally requires a permit, and Katy is no exception.
A permanent standby generator requires an electrical permit (and usually a gas or plumbing permit for the fuel line) in Texas cities, and electrical permits are typically issued only to registered master electricians. Placement must meet manufacturer and code clearances from openings and property lines. Confirm clearances and required permits with your local building department. Katy's electrical fee schedule lists a generator at $100, and its gas schedule charges $10 per gas appliance with a $15 minimum, each plus a $30 application fee (Appendix A, Sec. A4.001). Katy's Applications and Forms page notes that under Senate Bill 1202, effective September 1, 2025, qualified third-party professionals may review plans for and inspect home backup power installations in single-family and two-family dwellings. Katy Code Sec. 3.02.352 requires an electrical permit before any electrical apparatus is installed.
