Do I need a permit for standby generator installation in Unincorporated St. Lucie County?
Yes. In Florida, standby generator installation generally requires a permit, and Unincorporated St. Lucie 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.

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.
