FENCE RULES – KEY BISCAYNE (VILLAGE), FLORIDA

OVERVIEW

Residential fences are permitted on private property within Village of Key Biscayne, subject to local regulations.

For properties located outside Village of Key Biscayne municipal limits, Miami-Dade County regulates fences in unincorporated areas.

The primary residential fence standards appear in the Village of Key Biscayne Code of Ordinances, particularly section 30-100(6), Fences and Walls. Related provisions address vacant waterfront lots, waterfront view corridors, coastal flood-hazard conditions, pool barriers, property maintenance, and the Village’s published Fence Details.

This page focuses on typical single-family residential fencing. If the jurisdiction’s adopted code or ordinance materials do not state a specific limit or requirement, this page notes that the code does not specify one. If no local code or ordinance is available in the approved source packet, this page notes that the jurisdiction does not publish the relevant standard in the referenced published materials.

Compiled From the Village of Key Biscayne Code of Ordinances, Fence Details, Building, Zoning & Planning Department permitting materials, Zoning and Planning Division materials, the 8th Edition (2023) Florida Building Code, Chapter 2026-63, and section 556.105, Florida Statutes, as of July 2026.

GOVERNANCE

The governing authority is the Village of Key Biscayne.

The Village does not rely on a single standalone residential fence ordinance. Perimeter fence and wall standards for single-family and two-family residential districts appear in section 30-100(6), with related requirements in section 30-40 for vacant waterfront lots, section 30-100(28) for swimming-pool enclosures, section 30-100(29) for court-game fencing, section 30-100(32) for waterfront view corridors, section 10-99 for Coastal High Hazard Areas and Coastal A Zones, and section 5-3 for maintenance.

The Building, Zoning & Planning Department administers the Village permit process. The Zoning and Planning Division reviews building-permit plans and site plans for compliance with the Zoning and Land Development Regulations, and Code Compliance enforces the Village Code and applicable property-maintenance standards.

The current statewide building code is the 8th Edition (2023) Florida Building Code. The Village’s published fence construction details and residential pool-barrier requirements operate within that statewide code framework.

PERMIT AND APPROVAL REQUIREMENTS

Effective July 1, 2026, Florida’s HB 803, enacted as Chapter 2026-63, changed the building-permit framework for certain work on single-family residential property. A local government that issues building permits must exempt an owner of a single-family dwelling, or the owner’s contractor, from the requirement to obtain a building permit for work valued at less than $7,500 on the owner’s property. The exemption does not apply to work on property located partly or entirely in a flood hazard area as defined by the Florida Building Code, or to electrical, plumbing, structural, mechanical, or gas work performed on property containing a single-family dwelling. A construction project may not be divided into multiple projects to evade this rule. To qualify, the owner or the owner’s contractor must submit a written exemption request to the local enforcement agency with a contract or other documentation showing the nature and value of the work.

This statutory exemption concerns only the requirement to obtain a building permit. It does not eliminate separate requirements involving zoning, fence permits, setbacks, surveys, easements, rights-of-way, drainage, visibility, floodplain review, historic or design review, Certificates of Appropriateness, pool barriers, HOA approval, covenants, or other site-specific restrictions that may apply to the property.

The statute does not classify every fence project as structural or nonstructural. Unless the local permitting authority has published specific guidance for fence work under HB 803, whether a particular fence project qualifies for the valuation exemption depends on the nature of the work, the property location, and the applicable local permitting process.

• Fence Permit and Inspection: The Village publishes Fence Details as part of its permit-resource collection. The detail sheets establish permit and inspection requirements for standard wood, chain-link, and ornamental aluminum fence construction. The wood and chain-link details require a mandatory footing inspection before concrete is poured.

• Preassembled Wood Panels: Preassembled wood fence panels are not covered by the Village’s standard wood-fence detail. The applicant must obtain the product’s Notice of Acceptance Product Approval, submit it for permit, and construct the fence in accordance with that approval.

• Zoning and Planning Review: The Zoning and Planning Division reviews building-permit plans for compliance with the Village’s Zoning and Land Development Regulations. Residential perimeter fences are evaluated under the zone, height, setback, openness, screening, finish, and material requirements in section 30-100(6).

• Coastal Flood-Hazard Review: In a Coastal High Hazard Area (Zone V) or Coastal A Zone, solid fences, privacy walls, and fences prone to trapping debris are subject to section 10-99. The development must be authorized by the appropriate authority, located outside the footprint of and not structurally attached to a building or structure, and supported by a qualified registered design professional’s analysis showing no harmful diversion of floodwaters, wave runup, or wave reflection. A fence designed to fail below design-flood conditions or otherwise avoid obstructing floodwaters is addressed separately by that section.

• Pool-Barrier Review: A yard containing a residential swimming pool must be surrounded by a wall or fence and must satisfy the applicable residential pool-safety requirements. Where an adjacent lot’s wall or fence is used as part of the required safety feature, removal or destruction of that barrier requires the property owner to provide a compliant replacement wall or fence.

FENCE PLACEMENT RULES

• Fence Zones: For perimeter-fence regulation, the code establishes a Front Zone, Rear Zone, and Waterfront Zone. The Front Zone is the area between an enclosed building and a street-fronting property line, but never less than 15 feet from that property line. The Rear Zone extends from the back of the Front Zone to the rear property line or the Waterfront Zone. The Waterfront Zone is the entire area within 25 feet of a waterway.

• Front Zone Setback: A Front Zone fence has a minimum setback of 2 feet when a sidewalk is present and 0 feet when no sidewalk is present.

• Interior Side and Rear Property Lines: Outside the specific Front Zone, Waterfront Zone, court-game, flood-hazard, and waterfront-view-corridor provisions, the code does not specify a general setback for an ordinary perimeter fence from an interior side or rear property line. A permit issued for a fence along a common shared property line does not authorize encroachment, trespass, or entry onto adjacent property to perform the work.

• Waterfront View Corridor: On waterfront property, no structure is permitted within an isosceles triangle having 25-foot sides at the intersection of the rear and side lot lines; however, a hedge, wall, or fence not exceeding 4 feet is permitted within that corridor.

• Vacant Waterfront Lots: A vacant waterfront lot must have a 6-foot black- or green-coated chain-link fence along the portions of the site facing the water.

• Coastal Flood-Hazard Areas: Fence placement in a Coastal High Hazard Area or Coastal A Zone is subject to the site-location and flood-performance conditions in section 10-99, including separation from building footprints and the prohibition on harmful obstruction or diversion of floodwaters.

• Utility Safety: Florida law requires notice through the statewide notification system commonly operated as Sunshine 811 before excavation or demolition. For fence projects that involve digging, drilling, augering, boring, grading, or other movement of earth on land, notice must be provided not less than 2 full business days before excavation begins. Member operators mark or otherwise respond regarding covered underground facilities, and the excavator must verify the system’s positive responses before beginning excavation where required. This statewide utility-notice framework is separate from local fence permitting, zoning, development approval, easement limits, right-of-way approvals, floodplain review, stormwater review, drainage review, historic or design review, HOA restrictions, and other applicable requirements.

FENCE HEIGHT AND VISIBILITY RULES

• Front Zone Height: A fence or wall in the Front Zone is limited to 4 feet as measured from lot grade and may not exceed 6 feet above the crown-of-road elevation. Arches, columns, gates, and other ornamental entry features may extend to 8 feet.

• Rear Zone Height: The maximum height is 6 feet measured from the average lot elevation and may not exceed 8 feet when measured from the adjacent property. Arches, columns, gates, and other ornamental entry features may extend to 8 feet.

• Waterfront Zone Height: The maximum height is 4 feet, measured from the elevation of the lowest point of the rear yard.

• Front Zone Openness: A Front Zone fence must be at least 75 percent open.

• Vacant Waterfront Lot Height: The separate vacant-waterfront-lot requirement calls for a 6-foot black- or green-coated chain-link fence along the water-facing portions of the lot.

• Court-Game Fencing: A fence associated with a tennis court or similar court game is not permitted in a front yard or a side yard facing a street. In an interior side or rear yard, the maximum height is 10 feet and the fence must be set back 7.5 feet from the interior side or rear yard. When the fence faces a street, the maximum height is 10 feet and it must be set back to the side building line.

• Additional Visibility Standard: For an ordinary single-family perimeter fence, the code does not specify an additional numerical private-property street-corner or driveway sight-triangle measurement beyond the Front Zone height, openness, and setback requirements and the waterfront view-corridor rule.

MATERIAL AND CONSTRUCTION LIMITS

• Street-Facing Wood Fences: A wood fence facing a street must be screened with a hedge having a minimum planting height of 24 inches and spacing of 24 inches on center.

• Street-Facing Chain-Link Fences: A chain-link fence facing a street must be screened with a hedge having a planting height equal to the fence height and spacing of 30 inches on center.

• Finished-Side Orientation: A wood fence must have its structural side facing the interior of the property. A side adjacent to an existing fence or wall may remain unfinished only through the recorded-covenant process described in section 30-100(6).

• Chain-Link Finish: Chain-link fences must have a black or green finish.

• Prohibited Materials: Barbed wire and similar materials are not permitted.

• Wood-Fence Construction Detail: The Village’s standard detail uses pressure-treated No. 2-grade-or-better wood posts, galvanized nails and connections, and concrete footings sized and spaced according to the published fence-height table.

• Chain-Link Construction Detail: The Village’s standard detail requires chain-link fabric of at least 12.5 gauge, specifies post and footing sizes by fence height, and requires a top rail or top tension wire. A separate engineered design is required by the published detail for a chain-link fence over 12 feet.

• Ornamental Aluminum Detail: The published ornamental aluminum detail specifies 6061-T6 aluminum and requires aluminum in contact with concrete to receive the stated protective coating.

• Pool-Barrier Construction: When a fence serves as a pool barrier, the Village detail requires a nonclimbable configuration, rails facing the inside of the property, and pedestrian gates with self-closing and latching devices installed at least 54 inches above ground.

• Maintenance: Fences must remain structurally sound, in good repair, clean and sanitary, and free from infestation, solid waste, damage, rot, rust, and other deterioration addressed by section 5-3.

PRIVATE RESTRICTIONS

Private covenants, subdivision restrictions, deed restrictions, easements, and HOA or architectural-review rules operate independently of Village of Key Biscayne regulations and may be more restrictive than the Village’s published standards.

Effective July 1, 2026, section 720.3035(1)(c), Florida Statutes, as added by Chapter 2026-63, provides that an association or similar committee may not require issuance of a governmental building permit as a prerequisite to its review of structures or improvements. This rule does not eliminate HOA or architectural review.

REVIEW AND ENFORCEMENT CONTEXT

Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:

• Permit and Inspection Review: Whether the proposed fence follows the applicable Village detail, product-approval requirement, footing-inspection requirement, and permit submittal process.

• Zone, Height, and Placement Review: Whether the fence complies with the Front Zone, Rear Zone, Waterfront Zone, setback, openness, height, ornamental-feature, and waterfront view-corridor standards.

• Street-Facing Design Review: Whether a street-facing wood or chain-link fence provides the required hedge screening and whether the structural side of a wood fence faces the property interior.

• Waterfront and Flood-Hazard Review: Whether a vacant waterfront lot has the required water-facing fence and whether a fence in a Coastal High Hazard Area or Coastal A Zone satisfies section 10-99.

• Pool-Barrier Review: Whether a fence used to enclose a residential pool provides the required enclosure and gate, latch, nonclimbable, and rail-orientation features.

• Maintenance and Code Compliance: Whether an existing fence remains structurally sound, in good repair, properly finished, clean, and free from deterioration or other property-maintenance violations.
