Florida and local notes for Unincorporated Polk County
The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Polk County's own permitting office is the Polk County Building Division, reachable on 863-534-6080 at https://www.polkfl.gov/services/building/. Its online permit portal is https://aca-prod.accela.com/POLKCO/. 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. Polk County lists the change out of A/C equipment as work requiring a permit. Replacing existing mechanical units is exempt from plans examination, so a change-out permit does not go through plan review. For a virtual HVAC change-out inspection, Polk requires photos of the condenser anchors, the data plate maximum overcurrent protection, the disconnect, refrigerant line locking caps, condensate drains and float switches, heat strip size, and breaker sizes in the panel.
