Volusia County, FL Environmental Rules: Boat Dock Permits (2026)

Section 72-278 of the county's zoning code sets the construction standards for docks and boathouses on waterfront lots in unincorporated Volusia County. The dock area, including any boathouse, cannot exceed 750 square feet, though walkway extensions out to the water don't count toward that cap, walkways themselves are capped at eight feet wide. Boathouse area is measured as the square footage under roof. Only one dock is allowed per waterfront lot, and it must go on a lot that already meets the minimum area and width requirements for its zoning classification and complies with (or is exempt from) the shoreline provisions in article III, division 2.

Docks cannot be used for dwelling purposes or contain sleeping or living quarters. Height is capped at 15 feet above the mean high-water mark in tidal areas, or the ordinary high-water mark in nontidal areas, and no dock may sit within 15 feet of a side lot line or its extension into the water, a setback that applies in every zoning classification that allows boathouses and boat docks in waterfront yards. Section 72-278 also requires docks and boathouses to be designed and located consistent with the Land Development Code and the county's Manatee Protection Plan.

Separately, section 72-241 flags a conditional use permit trigger for larger commercial-scale docks: one exceeding 500 square feet of over-water surface in an Outstanding Florida Water, or 1,000 square feet elsewhere, requires county council conditional use approval rather than administrative permitting. Homeowners building a standard residential dock stay under the conditional-use threshold as long as they hold to the 750-square-foot cap in section 72-278.
