Volusia County stretches from the Atlantic coast at Daytona Beach inland to Deltona and DeLand. The county’s ADU picture is shaped by two overlays: the coastal high-hazard area (with building code and insurance implications) and the historic district designations in downtown DeLand and parts of Ormond Beach.

For inland homeowners in unincorporated Volusia, the ADU rules are relatively straightforward: 50% of principal residence, max 1,200 sq ft, min 240 sq ft, plus one additional parking space and owner-occupancy on parcels under one acre. For coastal homeowners, flood zone V and A requirements add elevation and structural requirements that roughly double per-square-foot construction cost.

Florida’s 2026 ADU preemption bill (SB 48) did not become law, so Volusia’s existing Code of Ordinances (including the coastal and historic-district overlays) remains the governing document unchanged. See the Florida ADU law pillar (or in Spanish) for the statewide legal picture and the SB 48 post-mortem for the legislative record.

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.
