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

Local and county notes for Jacksonville
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. Installing a permanently wired standby generator requires an electrical permit from the City of Jacksonville Building Inspection Division, with the electrical work done by a certified electrical contractor. A separate gas or plumbing permit, pulled by a certified contractor, is generally required for the natural gas or propane fuel connection. Confirm generator placement against zoning setbacks and, in coastal (wind-borne debris) areas, product and anchoring requirements.

Duval County's own permitting office is the Duval County Building Inspection Division, reachable on 904-255-8500 at https://www.jacksonville.gov/departments/public-works/building-inspection-division. Its online permit portal is https://jaxepics.coj.net/. 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.
