What does Austin require for a standby generator?
Austin offers a stand-alone SB 1202 permit for home backup generators, but gas work and utility shutdowns still need city permits. Here is how it works.
Austin lets contractors apply for a stand-alone trade permit for home backup power installations under SB 1202, with a third-party compliance letter signed by a licensed engineer or master electrician. Any project with natural gas or propane still needs a separate city plumbing permit, and any project requiring a shutdown needs a separate electrical permit and city inspections.
