Florida and local notes for Gainesville
The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Alachua County's own permitting office is the Alachua County Building Division, reachable on 352-374-5243 at https://growth-management.alachuacounty.us/building. Its online permit portal is https://www.citizenserve.com/alachuacounty. 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. Gainesville's Permit Exemption excludes electrical, mechanical, plumbing, and gas work, so this trade work needs its own permit regardless of cost. The code fee for each electrical, plumbing, gas, or mechanical permit is $72.50 (Appendix A). The Building Division offers virtual inspections by FaceTime or Skype for AC changeouts. LDC Sec. 30-6.10 says outdoor HVAC units may not sit between the building and the street unless the utility says it is the only feasible spot, and must be screened above their height when visible from the street or neighbors. For a property individually listed on the local register or contributing to a local historic district, installing an air conditioning unit or other mechanical equipment requires a Certificate of Appropriateness under LDC Sec. 30-4.28.
