Do You Need a Permit to Build a Fence in Miami?
Yes. The City of Miami Code requires a permit to construct or alter any structure, and its list of permit-exempt work (section 10-5(b)) contains no fence item, so a 4 foot picket fence and an 8 foot masonry wall both need a building permit. What the height controls is zoning, not whether you file. Miami 21 regulates fences by layer: in the T3 single-family zones a fence or wall in the first layer (between the house and the street) may not exceed 4 feet, except that aluminum or iron picket-and-post fences may reach 6 feet; in the second and third layers (sides and rear) the cap is 8 feet. First-layer pickets may be no more than 3 inches wide with at least 3 inches of clear space, and posts up to 2 feet square must be at least 5 feet apart. Walls enclosing an outdoor game court may go to 13 feet if they are transparent and buffered with landscaping.
Two more zoning rules catch homeowners. On a corner, nothing between 2.5 feet and 10 feet high may sit inside the visibility triangle formed by the first 25 feet along each right-of-way edge. And broken glass, projecting nails, razor wire and spikes are prohibited on any fence or wall in every transect; barbed wire is allowed only in the D1 to D3 industrial districts by Waiver.

How Much Does a Fence Permit Cost in Miami?
The city charges 0.50 of the estimated construction cost on every residential permit, read as one-half of one percent (the same section sets the commercial rate at one percent), with a $110 minimum and a flat $45 only when the whole job is under $2,500. Add the $40 application fee every permit carries, the city solid waste surcharge of $0.22 per $100 of cost with a $26 minimum and $600 maximum, state surcharges of 1 percent and 1.5 percent of the permit fee (at least $2 each), and a Miami-Dade County code-compliance surcharge whose rate the City Code does not print.
Worked example, a $6,000 wood privacy fence: 0.5 percent is $30, so the fee is the $110 minimum; with $40 application, the $26 minimum solid waste surcharge and $4 in state surcharges the city bill is about $180. A $30,000 masonry wall: fee $150, application $40, solid waste $66, state surcharges $4.25, about $260.25. The up-front fee of $2.80 per $1,000 collected at filing is 80 percent credited to the permit fee. A re-inspection is $57.
Who Pulls the Permit and How Long Does It Take?
A fence contractor must hold a Florida license or a Miami-Dade County certificate of competency, which the county requires in the City of Miami as in the unincorporated area. Owners of a one- or two-family home they occupy may file as owner-builder under Florida Statute 489.103(7) by appearing in person and signing the application. The City Code requires a single-family permit to issue within 30 working days unless unusual circumstances apply; the permit expires if work does not start within 180 days. Zoning review fees are set by City Commission resolution and are not published in the Code.
How to Get a Fence Permit in Miami
Find your layer and height limit
Locate the fence relative to the house: 4 ft (6 ft picket) in front of the facade line, 8 ft beside and behind it in T3 zones. Check the corner visibility triangle if applicable.
Draw the site plan
Show the fence line, heights, materials and gate locations on a survey, and note any pool it will serve as a barrier for.
Apply to the Building Department
File the application with the $40 fee and the up-front fee of $2.80 per $1,000 of value; a contractor or owner-builder must sign.
Pay the permit on approval
Most fences pay the $110 minimum plus the $26 minimum solid waste surcharge and state surcharges; the city must act on a single-family permit within 30 working days.
Build and call the final inspection
Start within 180 days of issuance. A failed or unready inspection costs $57 before the next one is scheduled.
