Florida and local notes for Unincorporated Hillsborough County
The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Hillsborough County's own permitting office is the Hillsborough County Development Services Department, reachable on (813) 272-5600 at https://hcfl.gov/businesses/permits-and-records. Its online permit portal is https://aca-prod.accela.com/HCFL/Default.aspx. 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. Hillsborough County's HB 803 exemption expressly excludes mechanical work, and its exempt list covers only portable units, part replacements that do not alter approval, and similar minor items, so an HVAC change-out needs a mechanical permit. For a project needing only a mechanical permit, including repair or replacement of an existing heating or air-conditioning system, the county requires a Notice of Commencement when the cost is $15,000 or more. Under LDC 6.01.03, an air-conditioning unit may not project into a required front yard, and may project only 5 feet into a required rear yard and the lesser of 3 feet or half of a required side yard.
