Do I need a permit for solar panel installation in Katy?
Yes. In Texas, solar panel installation generally requires a permit, and Katy is no exception.
Texas cities require both a building and an electrical permit for a rooftop solar system, and utilities such as Austin Energy require a separate interconnection approval in addition to the city permit. Ground-mount and building-integrated (solar-shingle) systems face additional plan-review and engineering requirements beyond a standard roof-mount array. Confirm scope with the local building department and your utility. Katy Code Sec. 3.02.352 requires an electrical permit before any electric wiring or apparatus is installed or changed, and Sec. 3.02.353 says the application must bear the signature of the master electrician. Under Katy Code Sec. 3.02.354, current may not be turned on to new wiring or apparatus until an electrical inspector issues a certificate of satisfactory inspection. Katy adopted the 2023 National Electrical Code (Code Sec. 3.02.331). Its local amendment (Sec. 3.02.332) says the electric utility may not require a meter on the front or street side of a building without the owner's written consent.
