Florida and local notes for Unincorporated Santa Rosa County
The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Santa Rosa County's own permitting office is the Santa Rosa County Development Services - Permitting & Building Compliance office, reachable on 850-983-1877 at https://www.santarosa.fl.gov/170/Permitting-Building-Compliance. 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. Santa Rosa County's mechanical permit application has a change-out option for condenser, evaporator or both, and the fee schedule sets a single-family heating, ventilation and A/C permit at $67.00 up to 5 tons. The county no longer accepts a balanced return air affidavit. HVAC contractors must provide a signed balanced return air data sheet or meet one of the transfer duct or transfer grille exceptions on the application. If the return air plenum is not built or sealed at the rough inspection, the county requires a separate plenum inspection, and finished work may have to be opened at final if it was never inspected.
