Florida and local notes for Unincorporated Brevard County

The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. Brevard County's own permitting office is the Brevard County Building Permits office, reachable on 321-633-2187 at https://www.brevardfl.gov/PlanningAndDevelopment/BuildingPermits/BrevardCountyBuildingPermits. Its online permit portal is https://aca-prod.accela.com/brevard/Default.aspx. 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. Brevard County publishes its wind speed requirements as a set of maps, one per Risk Category, that you search by street address. Most houses are Risk Category 2. Screen enclosures are explicitly Risk Category 1, which is a lower design requirement than the house they attach to. Be aware the county's own map instructions still tell you to install Microsoft Silverlight, which no current browser supports, so in practice you may need to call the Building Department on 321-633-2187 to get the design wind speed for your address. Brevard County requires a Residential HVAC/Mechanical permit to install new or replacement HVAC units, with or without ductwork. It is an expedited permit with no staff review, so a licensed contractor can obtain it online through BASS. For HVAC work the county's Notice of Commencement threshold is $15,000 of job value, higher than the $5,000 threshold on its other residential permits. The county's local building code exempts portable heating and cooling units and replacement parts that do not alter the equipment's approval from mechanical permits.
