Do I need a permit for standby generator installation in St. Augustine?
Yes. In Florida, standby generator installation generally requires a permit, and St. Augustine is no exception.
A permanently installed standby generator requires an electrical permit for the transfer switch, plus a gas or fuel permit for natural gas or propane connections, and often a building or structural review because the unit must be anchored for wind uplift. Portable generators are not permitted work, but any hard-wired or fuel-connected unit is. Propane tanks have separate siting rules.
Florida and local notes for St. Augustine
Requirements are multi-agency and can include zoning, fire, and environmental review for fuel tanks. Signed and sealed plans and wind-load anchoring are often required. St. Johns County's own permitting office is the St. Johns County Building Department, reachable on (904) 827-6800 at https://www.sjcfl.us/departments/building-department/. Its online permit portal is https://webapp.sjcfl.us/WATSWebX/Permit/SearchPermit.aspx. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Florida municipalities do not, this is the office that will handle the job. A permanent generator involves electrical and, on gas units, fuel gas permits, plus setback review for the pad. St. Augustine has a dedicated Generator permit type requiring specification sheets. Its Gas permit type requires a site plan showing the gas lines and the gas tank. Electrical and gas work need permits at any cost under the city's $7,500 exemption rules. Code Sec. 28-348(1)(d) keeps mechanical equipment serving the house out of required front yards and at least 10 feet from side lot lines unless screened by a qualifying wall or fence, so confirm the pad location with Planning and Building.
