Fencing in Key Biscayne: what makes this city different
Island salt exposure at its most aggressive, plus village design review. Everything we install here is stainless-fastened and marine-coated, no exceptions.
We work Key Biscayne constantly, which means we already know how the local review process behaves, which fence styles clear architectural approval, and what the ground does when the auger goes in. Shallow oolitic limestone is common here, so post holes frequently require rock augering or hammer work — a real cost line we identify on site rather than discovering mid-job.
Wind-load requirements affecting Key Biscayne

What fence holds up best in Key Biscayne during hurricane season?
Miami-Dade sits entirely inside the High-Velocity Hurricane Zone, with ultimate design wind speeds around 170–175 mph on the coast. Footers, post sizes and fastener grades all step up accordingly. In Key Biscayne we most often specify open-picket aluminum where privacy is not required, and reinforced vinyl on 6-foot post spacing with deep poured footers where it is.
How tall can my fence be in Key Biscayne?
Across Miami-Dade County the common standard is 4 feet in the front yard and 6 feet in side and rear yards, with corner-lot visibility triangles further limiting height near intersections. Key Biscayne may apply its own amendment, so we verify the current ordinance before designing your fence.
How soon can you install a fence in Key Biscayne?
We typically measure within 48 hours, quote within another 48, and install one to three weeks later depending on Key Biscayne permit review and any HOA architectural calendar. Emergency and storm-damage repairs are scheduled within 24 to 48 hours.
