Fence, concrete-wall, and pool-barrier installation and permits in the Village of Key Biscayne.

Serving the Village of Key Biscayne — an incorporated island municipality in Miami-Dade County, FL.

Allday Fence has worked Miami-Dade building departments for 18 years of experience. Key Biscayne is its own world: a barrier island reached only across the Rickenbacker Causeway, where waterfront estate lots, an exposed hurricane environment, and a Village that guards its streetscape with a three-zone fence code make a job about setbacks, hedges, wall finishes, pool-safety code, and product approvals as much as posts and panels — and where every material has to come over the causeway on schedule.

Why fences and walls are different on the Village of Key Biscayne

Key Biscayne incorporated as a Village in 1991, occupying the developed middle of a barrier island bracketed by two of the county’s great green bookends — Crandon Park to the north and Bill Baggs Cape Florida State Park, with its historic Cape Florida Lighthouse, at the south tip. Everything in between is a compact, affluent, single-family-and-condo community with one road on and off the island: the Rickenbacker Causeway, which lands on the mainland in the City of Miami near Brickell and Coconut Grove.

That geography drives the work. On the exclusive waterfront streets — Harbor Drive, West Mashta Drive, Bay Lane, and the estate lots of Mashta Island wrapping Hurricane Harbor — the typical job is a high-end pool barrier, a stuccoed masonry street wall with entry columns, and a perimeter fence that has to sit between a seawall and an open-water view. Along the interior streets feeding Crandon Boulevard, it is privacy and property-line fencing held to the Village’s street-facing setback-and-hedge standard. And on any island lot, wind exposure means product approval and engineering are not a formality. A homeowner used to a mainland subdivision usually gets the street elevation wrong on the first try.

We measure first. Then we build. Every Key Biscayne install starts with a MyHausFax™ property compliance report so we know the parcel’s permit history, open permits, setbacks, seawall/waterfront constraints, and any recorded restrictions before a post hole is ever marked.

Fence and wall permit rules on the Village of Key Biscayne

The framework below is drawn from the Village of Key Biscayne’s own zoning and land development regulations — Code of Ordinances Chapter 30, Sec. 30-100 (“Fences and Walls” and “Swimming pools”) — and the Village’s official building-permit application. Allday Fence confirms the current code against your exact address and zoning district before we quote, and we pull the permit.

A permit is required — and a fence is its own permit. The Village’s official permit application states in plain terms that separate permits are required for FENCE work (alongside electrical, plumbing, pool, mechanical, driveway, roofing, and signs). There is no no-permit tier.

Height is regulated by three zones — the headline difference. Key Biscayne does not use a simple front/side/rear-yard height table. Sec. 30-100 establishes three perimeter zones and caps height in each:

Front Zone (the area between the building and a street-facing property line, and in no event less than 15 ft from that line): a fence or wall is capped at 4 ft measured from the lot grade — and in no case more than 6 ft above the crown of the road — it must be at least 75% open, and it must be set back 2 ft where a sidewalk is present (otherwise it may sit on the line). Arches, columns, gates, and ornamental entry features may rise to 8 ft.
Rear Zone (from the back of the Front Zone to the rear property line, or to the Waterfront Zone): a fence or wall may reach 6 ft measured from the average elevation of the lot, and in no case more than 8 ft when measured from the adjacent property; arches, columns, gates, and ornamental features may reach 8 ft.
Waterfront Zone (the entire area within 25 ft of any waterway): height is held to 4 ft measured from the elevation of the lowest point of the rear yard. This is the rule that quietly governs most Key Biscayne waterfront lots.

Corner and driveway visibility (the sight triangle): at a street corner, a wall, fence, or landscaping is held to about 2.5 ft in height measured 15 ft along the intersection of the property lines, so drivers and pedestrians keep a clear sightline.

Screening the street elevation (a Key Biscayne signature): a perimeter wall or a wood fence facing a street must be screened with a planted hedge — at least 24 in tall at planting on 24-in centers for a wall or wood fence, and a hedge matching the height of the wall or chain-link fence on 30-in centers where those face the street. The Village wants the street edge green, not bare masonry or chain link. We design the hedge line into the plan so it is one approved package, not an afterthought.

Finished side, materials, and prohibited types:

All walls must be finished on every side — masonry walls stuccoed and painted; wood fences turned so the structural side faces the interior of the property. (One narrow exception: a new fence/wall abutting an existing neighbor’s fence may be left unfinished on that side only with a recorded covenant.)
Chain-link fences must be coated black or green. Chain link tied to court games (tennis/sport courts) is handled separately under the Village’s court-games provision.
Barbed wire and similar materials are not permitted.
Hedges themselves carry no separate height or setback cap except the line-of-sight requirement — but a hedge used as required street screening still has to be planted to the standard above.

Concrete and masonry walls + entry columns (our specialty license, in play on the island). Allday is a licensed specialty fence contractor whose scope covers concrete and masonry (CBS/block) walls and concrete columns, not just fabric fence. On Key Biscayne that’s real work: stuccoed Front-Zone street walls, 6-ft rear masonry walls, and entry columns up to 8 ft are all common here and all sit squarely in our license. But a concrete wall is not just a taller fence — once a CBS or poured wall gets beyond a low garden height it generally needs a footing, structural reinforcement, and engineer-sealed wind-load detailing to meet the hurricane zone, and the Village’s finish rules (stucco-and-paint, finished all sides) apply. We build the wall and its columns, carry the structural engineering, and pull the permit as one package. (Scope note: we install fences, freestanding concrete/masonry walls, and columns — not retaining walls or structural building walls.)

Pool-barrier fences (high-ticket island work). A residential pool on Key Biscayne must satisfy Florida’s Residential Swimming Pool Safety Act — Sec. 30-100 requires the pool to meet at least one of the approved safety features under F.S. 515.27, and adds a Village supplement: the Village will NOT accept a safety pool cover as that feature. The code also requires any yard with a pool to be surrounded by a wall or fence. Where the safety feature is the perimeter barrier, Florida’s pool-safety code calls for a non-climbable barrier at least 4 ft high with a self-closing, self-latching gate that latches beyond a child’s reach, passing the safety inspection as a condition of the pool’s approval. On waterfront lots the barrier also has to reconcile with the seawall and the 4-ft Waterfront-Zone height limit, which is where careful design earns its keep. See our pool-code barrier fencing.

Temporary construction fencing (island-specific staging). For a new home, substantial renovation, or demolition, the Village’s permit application spells out a staged construction fence: at least a 42-in plastic-mesh fence (or better) around the entire site at commencement, stepping up to a 6-ft chain-link fence with mesh once the foundation is complete (kept no closer than 3 ft to the pavement or an adjacent sidewalk), and back down to the 42-in plastic mesh once all the drywall is installed. We build the construction fence to that sequence and tie it to your permanent perimeter plan.

HVHZ and product approval (all of Miami-Dade, and an island really means it). Key Biscayne, like every Miami-Dade municipality, is in the High-Velocity Hurricane Zone — the most demanding wind zone in Florida’s code. Manufactured aluminum, PVC, and vinyl fence systems must carry a current Florida Product Approval or Miami-Dade Notice of Acceptance (NOA), and masonry walls, columns, and gate posts need engineer-sealed structural and wind-load detailing — genuinely load-bearing on an open-water barrier-island lot. The Village’s permit application confirms structural calculations are a required attachment where the scope calls for them. The exact product approvals the Village wants itemized on a given fence submittal we confirm with Building, Zoning and Planning for your specific system.

Survey and site plan. A current survey of the property is a listed item on the Village’s own permit processing checklist. For a fence or wall we pair that survey with a scaled site plan showing the fence/wall location, heights by zone, setbacks, hedge line, and any seawall, and we confirm the exact site-plan detail the Village wants for your specific scope when we file.

HOA, condo association, and design restrictions. Most single-family Key Biscayne homes are not inside a mandatory HOA, but the island’s condominium and townhome communities — Key Colony, the Ocean Club, Grand Bay, and similar — carry their own association architectural approval on top of the Village permit, and the Village’s own permit application even lists a “Condominium Association letter of approval” among the attachments where it applies. Individual deed restrictions also exist on the exclusive streets. This is private association and covenant review, not a Coral Gables-style municipal design board. We check recorded restrictions up front before design so a compliant fence isn’t stopped by a private covenant or a missing association sign-off.

Fees and timeline run off the Village permit fee schedule and are valuation-based — there is no reliable published flat fence fee, and we do not print a turnaround we can’t stand behind. We confirm current cost and timing with Building, Zoning and Planning as part of your quote.

Framing line: Zone heights, setbacks, hedge screening, wall finishes, and pool-barrier details vary by parcel, zoning district, waterfront condition, and any recorded covenant — we confirm the current Key Biscayne code for your exact address before we quote, and we pull the permit.

The permitting authority and how a Key Biscayne fence or wall project runs with Allday

Key Biscayne runs its own building department — it does not permit through Miami-Dade County. Everything files through the Village of Key Biscayne Building, Zoning and Planning Department at 88 West McIntyre Street, Suite 250, with electronic application and plan intake through the Village’s Accela Citizen Access (ePermits) portal. The department’s direct line is 305-365-5512 (the main Village line is 305-365-5511); confirm counter hours by phone before a walk-in.

Property record pulled. We run the MyHausFax™ report and pull the Village permit history — open permits, setbacks, seawall/waterfront constraints, recorded restrictions — before we quote.
Design to the Village’s three-zone standard. We design the street (Front Zone) elevation to the 4-ft/75%-open + setback + hedge rule, hold the Waterfront Zone to 4 ft, size the Rear-Zone runs to 6 ft, keep the corner sight triangle clear, detail any masonry wall and entry columns, and design any pool barrier to F.S. 515.27.
Full package filed. Application, survey and site plan with the hedge line shown, product approvals / engineer-sealed structural and wind-load detailing for HVHZ (walls, columns, manufactured systems), and pool-barrier specs where they apply — assembled the way Building, Zoning and Planning expects and filed through Accela.
Review and corrections. We carry the submittal through zoning and building review and respond to any corrections.
Install + inspections — with island logistics handled. Built to the approved plans, materials staged for the Rickenbacker Causeway run, walked with the Village inspector, corrections resolved on site — including the pool-barrier safety inspection where a pool is involved.
Permit closed against the record. Closed in writing against the property record. If a fence, wall, or pool barrier is already up without a permit, our sister company Permit Solutions Services runs the after-the-fact path.

Key Biscayne · fence questions

Common Key Biscayne fence questions.

Why can't I run a solid wall straight to the sidewalk across the front of my Key Biscayne home?

Because the Village regulates the street-facing edge of your lot under a three-zone system in its Chapter 30 zoning code (Sec. 30-100, 'Fences and Walls'). In the 'Front Zone' — the area between your house and a street-facing lot line, at least 15 feet deep — a fence or wall is capped at four feet measured from the lot grade (and never more than six feet above the crown of the road), it has to be at least 75 percent open, and it must be set back two feet where a sidewalk is present. On top of that, a perimeter wall or wood fence facing the street has to be screened with a planted hedge (at least 24 inches tall at planting on 24-inch centers; a hedge matching the wall or chain-link height on 30-inch centers where those face the street). So a solid six-foot wall marching to the pavement across your front simply isn't allowed — the full-height, solid run belongs on your interior and rear lines. We design the street elevation to the Front-Zone standard so it clears the Village the first time.

What does Key Biscayne require for a swimming-pool safety barrier?

A residential pool on Key Biscayne has to satisfy Florida's Residential Swimming Pool Safety Act. The Village code (Sec. 30-100, Swimming pools) requires the pool to meet at least one of the approved safety features under F.S. 515.27 — and adds a Key Biscayne-specific twist: the Village will NOT accept a safety pool cover as its safety feature, so that option is off the table here. In practice that most often means a code-compliant barrier at least four feet high, non-climbable, with a self-closing, self-latching gate that latches out of a child's reach. The code also requires that any yard with a pool be surrounded by a wall or fence. Because so many Key Biscayne lots are waterfront with the pool between the house and the bay, the barrier has to reconcile the safety code with the seawall, the 25-foot waterfront height limit, and the view — exactly the kind of high-ticket job we scope carefully before we quote.

My Key Biscayne teardown needs a construction fence — what does the Village actually require during the build?

The Village has a specific staged construction-fence sequence for new homes, substantial renovations, and demolitions, and it's spelled out right in the building-permit application. At the start of work you need at least a 42-inch plastic-mesh fence (or better) around the entire site. Once the foundation is complete, that steps up to a 6-foot chain-link fence with mesh (it controls dust), kept no closer than 3 feet to the pavement or an adjacent sidewalk. Then, once all the drywall is installed, the 6-foot chain link can come back down to the 42-inch plastic mesh. It's a Key Biscayne-specific staging rule most homeowners and even some builders miss. We handle the construction fencing to that sequence and coordinate it with your permanent perimeter fence, wall, or columns.

Can Allday build a concrete or CBS wall and entry columns on Key Biscayne, not just a fence?

Yes. Allday Fence is a licensed specialty fence contractor whose scope covers any fence type plus concrete and masonry (CBS/block) walls and concrete columns — so a stuccoed street wall, a 6-foot rear masonry wall, or a set of entry columns is squarely our work, and we self-perform it under our own license. A masonry or concrete wall is not just a taller fence, though: once a CBS or poured-concrete wall goes beyond a low garden height it generally needs a footing, structural reinforcement, and engineer-sealed wind-load detailing to meet Miami-Dade's High-Velocity Hurricane Zone — and the Village requires all walls to be finished on every side and masonry stuccoed and painted. We handle the wall AND its concrete columns, carry the structural engineering, and pull the permit as one package. (We build fences, freestanding concrete/masonry walls, and columns — not retaining walls or structural building walls.)
