Do I need a permit for standby generator installation in Unincorporated St. Johns County?
Yes. In Florida, standby generator installation generally requires a permit, and Unincorporated St. Johns County 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 Unincorporated St. Johns County
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. Johns County's Generator Worksheet requires a separate gas or piping permit when the generator uses a new fuel source, and states that equipment serving the building must meet the minimum elevation requirement and zoning setbacks. Land Development Code Sec. 6.04.06.F.7.d lists emergency generators among the permanent structures barred from drainage and utility easements unless the County Administrator approves. Equipment serving the house may sit in a side or rear yard but not less than 5 feet from any lot line under Sec. 2.02.04.B.5.
