Do I need a permit for standby generator installation in Coral Gables?
Yes. In Florida, standby generator installation generally requires a permit, and Coral Gables 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 Coral Gables
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. The generator has to be anchored for HVHZ wind loads, and the pad, gas piping and transfer switch are each reviewed. Your city issues the permit, not the county. Miami-Dade County's own building department serves the unincorporated area, while each municipality runs its own building department, and the county Board of Rules and Appeals interprets the code across all of them. Coral Gables' FAQ states a generator needs an Electrical permit and, if gas powered, a Plumbing Gas sub-permit, and Board of Architects review may be required. Zoning Code 3-317 bars generators from the front setback and requires 10 feet from the rear line, 5 feet from interior side lines, 15 feet from a waterway or rear street, and at least 10 feet from any neighboring occupied building. One generator is allowed per single-family home. Generators must be fully screened with landscaping. One between the house and a street is limited to 4 feet high and 20 square feet; elsewhere the limit is one half percent of the site area or 100 square feet, whichever is less.
