Florida and local notes for Unincorporated Lake County
The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Lake County's own permitting office is the Lake County Office of Building Services, reachable on 352-343-9653 at https://lakecountyfl.gov/building-services. Its online permit portal is https://mcdplus.lakecountyfl.gov/oprs_PT/. 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. Lake County Code Sec. 6-3 requires a permit before installing or replacing mechanical work, and the county has a dedicated Mechanical Changeout Checklist (CL10). The Mechanical System Change Outs form (BF65) must be on site for the building inspector during inspections. For mechanical change-outs, Lake County sets the Notice of Commencement threshold at job values over $15,000, rather than the $5,000 used on its other checklists.
