Volusia County regulates accessory dwelling units on parcels in unincorporated Volusia through the Volusia County Code of Ordinances, Chapter 72 (Land Development Code), Article II (Zoning). Accessory living quarters and guest cottages are addressed in the county's zoning use tables; the county permits attached and, in some zoning districts, detached ADUs subject to lot size, setback, and occupancy conditions. Florida has no statewide ADU preemption; § 163.31771 FS is permissive only, so Volusia's local standards control. Pending SB 48 / HB 313 (2026 legislative session) would establish a statewide ADU floor with a December 1, 2026 local-ordinance conformance deadline if enacted.

• Volusia County Code of Ordinances, Chapter 72 — Land Development Code
• Florida Statutes § 163.31771 — Accessory Dwelling Units

State-floor overlay: Florida has no statewide ADU preemption as of April 2026. § 163.31771 FS is permissive only. Pending 2026 bills (SB 48 / HB 313) would impose a statewide floor requiring local ordinances to allow at least one ADU on single-family parcels meeting minimum lot size, with a December 1, 2026 conformance deadline for non-compliant ordinances. Volusia's current ordinance would need audit against the final text if either bill becomes law.

Volusia County administers coastal, floodplain, and environmental overlays that cut across multiple jurisdictions and materially affect ADU siting, particularly on the Atlantic-facing coastal corridor from Ormond Beach through New Smyrna Beach. The county's east side faces hurricane exposure (Zone AE, VE FEMA flood designations on barrier islands and along the Intracoastal Waterway) and is subject to the state's Coastal Construction Control Line program. Interior west-side parcels face St. Johns River Water Management District wetland and floodplain jurisdiction.

• FEMA Special Flood Hazard Areas (SFHA) — Volusia participates in the National Flood Insurance Program and enforces FEMA-mapped SFHAs through the county floodplain-management ordinance. Coastal parcels on barrier islands (Daytona Beach Shores, Ponce Inlet, northern New Smyrna Beach) and along the Intracoastal Waterway face Zone AE, VE, or Coastal A designations. An ADU proposed in a Zone AE or VE area faces elevation (above base flood elevation plus freeboard), breakaway-wall, and flow-through venting requirements that materially change construction cost. Volusia participates in the NFIP Community Rating System with a CRS class that yields policyholder premium discounts.
• Coastal Construction Control Line (CCCL) — Parcels east of the CCCL in Volusia (oceanfront barrier-island parcels in Ormond Beach, Daytona Beach, Daytona Beach Shores, Ponce Inlet, New Smyrna Beach) require an FDEP CCCL permit in addition to county permits. The CCCL permit governs foundation design, dune impact, and major-structure siting. An ADU proposed seaward of the CCCL line is subject to the same permit requirements as a primary structure and may be infeasible depending on dune proximity and erosion-rate mapping.
• St. Johns River Water Management District Wetland and Consumptive Use Permits — Parcels containing or adjacent to jurisdictional wetlands (including isolated wetlands over 0.5 acres) require SJRWMD Environmental Resource Permits. ADU site work (clearing, filling, stormwater management) that affects wetlands triggers ERP review, wetland delineation, and mitigation if unavoidable impacts are proposed. West-side Volusia parcels in the St. Johns River floodplain corridor (Pierson, Seville, parts of rural DeLand and Deltona) are affected more often than coastal parcels.
• Volusia County Environmental Core Overlay (ECO) / Conservation Overlays — Volusia's Comprehensive Plan designates Environmental Core and Conservation overlays to protect sensitive habitat, scrub ecosystems (critical for Florida scrub-jay and gopher tortoise populations), and the Blue Spring / Lake Woodruff / Tomoka river corridors. Parcels inside these overlays face lower permitted density and additional environmental review for any ADU addition. The overlays cut across multiple unincorporated areas and into several incorporated cities that use the county Comprehensive Plan as their framework.
• Hurricane Wind Zone / High Velocity Hurricane Zone (HVHZ) — Volusia's Atlantic coast is in the 140-150 mph ASCE 7-22 ultimate design wind-speed zone (Risk Category II residential); Volusia is NOT in the South Florida HVHZ (which is limited to Miami-Dade and Broward) but still requires impact-rated windows/doors or hurricane shutters on coastal parcels. ADU construction on barrier islands and within one mile of the coast faces the stricter enclosure-opening protection standards and elevated construction costs relative to inland parcels.
• Historic Overlay Districts (county-level) — Several unincorporated Volusia communities (Cassadaga, Enterprise, Glencoe, Osteen) contain historic-overlay designations that impose architectural-compatibility review on new construction and accessory structures. An ADU in one of these districts requires Historic Preservation Board review in addition to standard zoning and building review.

Permits for ADUs on parcels in unincorporated Volusia County are issued by the Volusia County Growth and Resource Management Department. Growth and Resource Management combines planning/zoning review, building-code review, and environmental permitting review under one department. Volusia's sixteen incorporated cities (Daytona Beach, Deltona, Port Orange, DeLand, Ormond Beach, New Smyrna Beach, Edgewater, Holly Hill, South Daytona, Lake Helen, Orange City, DeBary, Oak Hill, Pierson, Ponce Inlet, Daytona Beach Shores) handle their own ADU permits; this record applies only to unincorporated parcels.
