The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Hernando County's own permitting office is the Hernando County Building Division, reachable on 352-754-4050 at https://www.hernandocounty.us/building-development/building/. Its online permit portal is https://www.hernandocounty.us/CivicAccess. It issues permits for the unincorporated county.

A change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test.

Repair of existing mechanical equipment and window units using an existing outlet are on the county's no-permit list. Under local FBC 105.8, a recorded Notice of Commencement must be filed before the first inspection when the direct contract to repair or replace an existing heating or air-conditioning system is $7,500 or more.
