Do I need a permit for standby generator installation in Mary Esther?
Yes. In Florida, standby generator installation generally requires a permit, and Mary Esther 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.
