Dunnellon, FL Fence Regulations: Height Limits (2026)

Marion County regulates fences far more loosely than incorporated cities. The Land Development Code (LDC) has no dedicated 'Fences and walls' section establishing a maximum residential fence height; instead, Section 4.1.4 (General provisions and regulations) lists fences among structures that are exempt from the Code's setback requirements, meaning a fence may generally be placed at the property line. The principal height-related trigger is the building-permit threshold administered by the Building Safety Department: per the county's permitting guidance, a building permit is required when a fence will exceed 6 feet in height, when it is a wall-like masonry or concrete fence, or when it functions as a barrier around a swimming pool. Where the LDC and county practice are silent on a specific dimensional cap, Florida's general framework and the Florida Building Code govern through the permit process. Corner-lot and intersection visibility is preserved separately through the sight-triangle construction standards referenced in LDC Section 7.3.1, which keep visual obstructions low near street and driveway intersections. Property owners should confirm height and placement with Marion County Growth Services (352-438-2600) and Building Safety (352-438-2400) before construction.
