Florida and local notes for Naples
The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Collier County's own permitting office is the Collier County Building Plan Review and Inspection Division, reachable on 239-252-2400 at https://www.collier.gov/Business-Resources/Building-Permits-Construction. Its online permit portal is https://cvportal.collier.gov/cityviewweb. 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 change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test. Naples exempts A/C repair and replacing a window A/C unit on existing electrical, but a system change-out uses the city's Like for Like Replacement Permit Application, which requires an AHRI certificate. In AE, AH, and VE flood zones, the mechanical checklist requires new equipment to be elevated to Base Flood Elevation plus 1 foot. Under Naples Code Sec. 56-41, replacement A/C equipment cannot encroach more than 36 inches into a required yard and must be screened to its full height.
