Flagler County, FL Building Setbacks & Zoning: Lot Coverage Limits (2026)

Flagler County's Land Development Code sets lot coverage limits district by district rather than countywide. 5 caps coverage at twenty-five percent of the total lot area for principal and accessory buildings combined, on parcels that must meet a 20-acre minimum lot size and a 400-foot minimum lot width under the same dimensional-requirements section. That 25 percent limit is comparatively tight because the AC-2 district exists to keep large working agricultural and forestry tracts predominantly open, unlike the adjacent AC Agriculture district, which allows up to 35 percent coverage on its smaller 5-acre minimum lots, or the R-1 Rural Residential district, which allows 30 percent coverage.

A property owner calculating buildable area on AC-2 land needs to total every principal and accessory structure on the parcel, including barns, sheds and garages, against that 25 percent ceiling before applying for a building permit through the county's growth management department. Because the coverage percentage and the acreage thresholds that trigger it are set independently for each zoning district in Article III of the Land Development Code, a figure quoted for one district cannot be assumed to carry over to another, and none of these unincorporated-county figures apply to land inside Palm Coast, Flagler Beach, Beverly Beach, Bunnell or Marineland, each of which sets its own lot coverage limits under its own code.
