Glossary
Fence terms, defined in plain English.
The vocabulary that shows up in fence quotes, permit paperwork, and HOA applications around Boca Raton, defined in plain English. Read the terms that appear in your quote and the quote gets easier to compare.
- Linear foot
- The unit fence pricing is quoted in: one foot measured along the fence line, regardless of height. A rectangular quarter-acre backyard typically needs 140 to 180 linear feet. Height, material, gates, and tear-out then adjust the per-foot number into a project total.
- Post embedment
- How deep the fence post sits in the ground. In sandy South Florida soil with hurricane wind loads, posts are set deeper than national norms, commonly a third of the above-ground height or more, in concrete. Shallow embedment is the number one reason fences lean after their first tropical storm.
- Footing
- The concrete mass a fence post is set in. Footing diameter and depth come from the engineered spec for the fence system and wind zone, not from habit. Bigger and deeper on solid privacy fences, which carry the most wind load.
- Wind load
- The force wind applies to a fence, driven by design wind speed and how solid the fence is. A solid 6 foot privacy panel takes far more load than open picket at the same height. Florida Building Code wind provisions are why fence systems here come with engineering sheets specifying post spacing and embedment.
- High-Velocity Hurricane Zone (HVHZ)
- The strictest wind region in the Florida Building Code, covering Broward and Miami-Dade counties. Deerfield Beach, Parkland, Coral Springs, Coconut Creek, and Lighthouse Point all sit inside it. Fence products there generally need tested product approvals and tighter installation specs than in Palm Beach County.
- Product approval
- Documentation that a building product, including fence systems, has been tested and approved for use under Florida code, either through the statewide product approval system or the Miami-Dade notice-of-acceptance process used across the HVHZ. Permit packages in Broward lean on these documents.
- Wind-borne debris region
- The coastal zone in the Florida Building Code where design must account for debris carried by hurricane winds. Effectively all of the Boca Raton area falls in it. For fences, the practical consequence is the engineering rigor applied to posts, footings, and panel attachment.
- Stockade fence
- The basic wood privacy style: pickets butted edge to edge on one side of the rails. Cheapest to build, but pickets shrink as they dry and develop visible gaps within a year or two. The neighbor sees rails and posts, you see pickets.
- Shadowbox fence
- A wood style with pickets alternating on both faces of the rails, so the fence looks finished from both sides, a frequent HOA requirement. Allows airflow, which helps in wind, but has angled sight lines through the gaps.
- Board-on-board fence
- A wood privacy style with overlapping pickets, so shrinkage never opens a gap. The style that stays fully private for its whole life, at a modest premium over stockade. The usual pick for tight lot lines and pool surrounds in the older East Boca neighborhoods.
- Pressure-treated pine
- Southern yellow pine infused with preservatives under pressure, the only wood that makes economic sense for fencing in South Florida. Posts should carry a ground-contact treatment rating. Even treated, expect 10 to 15 years of life in this climate.
- Ground-contact rating
- A treatment level for pressure-treated lumber intended to touch soil or sit in concrete, roughly double the preservative retention of above-ground lumber. Posts are the part of a wood fence that fails first, and this rating is why the good ones last.
- Vinyl (PVC) fencing
- Fencing extruded from polyvinyl chloride. Immune to rot, termites, and salt corrosion, never needs paint. Quality varies enormously by wall thickness and UV package; wind-rated panels with aluminum-reinforced bottom rails are the grade that belongs in South Florida.
- Co-extrusion
- The manufacturing method behind quality vinyl fencing: an outer layer rich in UV inhibitors bonded over a structural core. It is why modern vinyl holds its color in Florida sun where older single-layer product yellowed and chalked.
- Aluminum picket fence
- Powder-coated aluminum panels with vertical pickets, the coastal South Florida standard for pool barriers and view fencing. Cannot rust, lets wind pass through, and racks to follow grade. Residential, commercial, and estate gauges differ in wall thickness and price.
- Powder coating
- A baked-on polymer finish applied electrostatically to aluminum fencing, far more durable than paint. Quality powder coat over a marine-grade alloy is what lets a black aluminum fence sit a block from the Intracoastal for decades.
- Rackable panel
- A fence panel whose pickets can pivot slightly so the panel follows sloping ground without stepped gaps underneath. Matters for pool code, where a gap under the fence can break compliance, and for the berms and swales common on South Florida lots.
- Chain link fabric
- The woven wire mesh of a chain link fence, sold galvanized or vinyl-coated in black or green. Gauge (wire thickness) and mesh size set strength and price. Black coated fabric behind a hedge is the most invisible fence money can buy.
- Tension wire
- A wire run along the bottom (and sometimes top) of chain link fencing to keep the fabric taut. The bottom run is what stops dogs from pushing under, cheaper and cleaner than burying the fabric.
- Pool barrier
- The safety fence required around residential pools under Florida's Residential Swimming Pool Safety Act (Chapter 515, Florida Statutes): minimum 4 feet high, no openings a young child could pass through, no climbable features, with self-closing, self-latching gates opening away from the water.
- Self-closing, self-latching gate
- A gate that swings shut on its own, spring or hydraulic hinges, and latches without human help, with the latch release positioned out of a small child's reach. Required on gates serving pool barriers and the first thing a pool inspection checks.
- Removable mesh pool fence
- Tensioned climb-resistant mesh panels on poles that socket into sleeves core-drilled in the pool deck. Meets barrier requirements when installed to spec, and can be taken down and re-installed by the owner. The standard choice for families who want the barrier now and the open patio later.
- Gate operator
- The motor system that automates a driveway gate: swing-arm or slide, with keypads, remotes, or phone-app control. Safety photo-eyes and entrapment protection are required parts of a proper install, and battery backup keeps the gate working through storm outages.
- Cantilever slide gate
- A sliding driveway gate that hangs from rollers and floats over the opening without a ground track, the preferred slide design where leaves and sand would jam a track. Common on wider West Boca and Parkland driveways.
- Sag rod (truss rod)
- A diagonal tension rod on a wide gate that pulls the free corner up toward the hinge side, preventing the racking that makes gates drag. Standard equipment on wood and chain link gates past about 4 feet wide.
- Setback
- The required distance between a structure and a property line or street. For fences, the practical setbacks are the front-yard height limit zone and corner-lot rules; City of Boca Raton code allows taller corner-lot fencing only at a distance from the side street with landscaping.
- Sight triangle
- The zone at corners and driveways that must stay visually clear so drivers can see, which limits fence height and placement there. A frequent constraint on the older gridded plats of East Boca and one the permit review checks.
- Architectural review board (ARB)
- The HOA committee that approves exterior changes, including fences, in most West Boca and gated communities. Applications typically need the style, height, color, manufacturer spec sheet, and a site plan. Approval comes before the city or county permit gets filed.
- Property survey
- The drawing of your lot showing boundaries, easements, and structures, usually produced at closing. It is the document a fence gets laid out from, and permit applications in this area commonly require it. Missing pins get re-marked by a surveyor, cheap insurance against building on the wrong line.
- Easement
- A right for a utility or drainage authority to use part of your lot. Fences often may cross utility easements but can be removed at the owner's cost if the utility needs access, and drainage easements along the lake systems in West Boca frequently prohibit fencing outright. The survey shows where they run.
- Certificate of competency
- The county-issued specialty license under which most fence contractors in Palm Beach and Broward counties operate, distinct from a state contractor license. It is what allows a company to pull fence permits in that county.
- Other-structures coverage
- The section of a Florida homeowners policy, commonly 10 percent of the dwelling limit, that covers detached structures including fences. Wind is a covered peril on most policies, subject to the hurricane deductible, which is why big storm losses claim well and small ones often do not.
