Frequently asked questions

Do I need a permit for a whole-house generator?

Yes. Standby generator installations in Florida generally require building, electrical and gas or fuel permits, plus setback review for the equipment location and a wind-rated anchoring detail.

What size generator do I need?

Essential-circuit coverage typically needs 10-14 kW, while whole-home coverage for a Florida house with central AC usually needs 20-26 kW. Sizing depends on your AC tonnage, water heater type and well pump if present.
