Dunnellon, FL Fence Regulations: Permit Requirements (2026)

Fence permitting in unincorporated Marion County is administered by the Building Safety Department (352-438-2400), with zoning placement reviewed by Growth Services (352-438-2600). Under the county's permitting guidance, an ordinary residential fence 6 feet or less in height typically does not require a building permit, while a building permit is required when a fence exceeds 6 feet, when it is a wall-like fence built of masonry or concrete, and when it serves as a barrier around a swimming pool. The Land Development Code reinforces that fences can be permit-triggering structures: in addressing screening of commercial vehicles, Section 4.3.21 provides that the screening 'wall or fence' must be high enough to screen the vehicle and parenthetically notes that 'walls and fences may require a building permit from the County.' Fences that require a permit must also meet the Florida Building Code's structural and wind-load standards administered through that permit, and pool-barrier fences must additionally satisfy Florida Statutes Chapter 515. Because fences are exempt from setbacks under Section 4.1.4, the permit review focuses on height, construction, wind load, and pool-safety rather than placement, though corner sight triangles still apply.
