Fences and walls shall conform to the following standards: Within the First Layer, Fences and walls may be located up to and including the Frontage Line. Within the First Layer, the Height of Fences and walls shall not exceed four (4) feet, except aluminum or iron picket and post Fences with or without masonry posts shall not exceed six (6) feet.

Full Breakdown
Miami 21, the city's form-based zoning code, sets fence and wall standards by Transect Zone rather than a single citywide limit. In T3 (the Sub-Urban Zone covering most single-family and duplex neighborhoods), Section 5.3.2 caps First Layer (front-yard) fences at 4 feet, or 6 feet for aluminum/iron picket-and-post fences with 3-inch-wide pickets and 3-inch gaps; Second and Third Layer (side/rear yard) fences and walls may reach 8 feet. Taller Transect Zones (T4, T5, T6) have their own fence-height rules in Article 5. Citywide, Section 3.7.2 bars broken glass, projecting nails, coiled razor wire and spikes on any fence or wall in any Transect Zone, and permits barbed wire only in the D1-D3 industrial zones by Waiver.
Violations & Fines
A fence exceeding these Layer height limits is a Miami 21 zoning violation subject to the city's code enforcement process; the excess height must be removed or, for uses like enclosed outdoor Game Courts, approved through the code's Waiver process rather than built as-of-right.
