The biggest number in a Volusia County ADU budget is not the size cap or the impact fee. It is your FEMA flood zone. On V and A zone parcels near the Atlantic coast, elevation and structural requirements roughly double per-square-foot construction cost compared to the same unit built inland. Volusia stretches from Daytona Beach on the coast to Deltona and DeLand inland, and two overlays shape the ADU picture across that width: the coastal high-hazard area, with its building code and insurance implications, and the historic district designations in downtown DeLand and parts of Ormond Beach.

Away from both overlays, in unincorporated Volusia, the rules are relatively straightforward: 50% of the principal residence, max 1,200 sq ft, min 240 sq ft, one additional parking space, and owner-occupancy on parcels under one acre.

Coastal parcels: check the flood zone before pricing anything Look up your parcel at msc.fema.gov before you price a coastal ADU project. A V or A zone designation changes the budget more than any other single factor in this county.

SB 48 did not become law, so the Code of Ordinances, coastal and historic-district overlays included, is still what governs. Statewide context: the Florida ADU law page.

Short-term rental interactions

Volusia’s STR regulation is handled at the municipal level. Daytona Beach allows STRs with registration; most other municipalities restrict them. Any ADU used as a short-term rental is therefore governed by the municipal STR ordinance in addition to the county ADU rules.

If you are considering an ADU in Volusia primarily for STR income, your governing document is the municipal short-term rental ordinance for your specific city. That ordinance has not been preempted by any state law in 2026.
