Flagler County, FL Zoning Overlays & Bonuses: Density Bonus Law (2026)

The R-3b Multifamily Residential district is the one place in Flagler County's Land Development Code that ties a numeric density increase to affordable housing. 2 sets a base maximum density of nine units per acre, then adds an affordable multifamily density bonus of an additional one unit per acre for a total of ten units per acre, provided the developer meets defined eligibility criteria. To qualify, at least 10 percent of the project's units must be designated affordable multifamily units for low- and moderate-income households, defined as households earning up to 100 percent of the county's median income adjusted for family size and paying no more than 30 percent of income on rent or purchase.

No more than 30 percent of a project's units may be designated for low-income households, below 80 percent of median income, and no more than 30 percent for moderate-income households, 80 to 100 percent of median income, and at least 40 percent of the units in the project must remain market rate. The property owner must record a land use restriction agreement with the county fixing the affordability terms, rent and income limits for a minimum 15-year period, and must submit an annual compliance report to the county throughout that period.

2. This density bonus applies only to R-3b-zoned land in unincorporated Flagler County; it has no bearing on multifamily zoning inside Palm Coast, which administers its own density standards under its own Unified Land Development Code.
