Local and county notes for South Bay
The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Palm Beach County's own permitting office is the Palm Beach County Planning, Zoning & Building Department (Building Division), reachable on 561-233-5100 at https://discover.pbc.gov/pzb/pages/contact-us.aspx. Its online permit portal is https://pbc.gov/epzb. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job. Palm Beach County is a high-wind area. The county's own amendments set ultimate design wind speeds ranging from 140 to 180 mph 3-second gust for Exposure Category C, depending on the Risk Category assigned to the building. All of unincorporated Palm Beach County is in the wind-borne debris region. Inside a municipality the exact wind speed and debris region lines are set by local ordinance, so confirm the figure for your parcel rather than assuming. Outdoor equipment is anchored to resist the design wind speed, and elevated stands are common here. South Bay permits are handled by the South Bay Planning and Building Department, reachable on 561-996-6751 at https://southbaycity.com. Palm Beach County also issues permits for the unincorporated county, and many smaller Florida municipalities contract building services to it rather than running a department of their own, so confirm which office covers your address before you apply. A change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test.
