Short answer: Split rail is the open, two- or three-rail fence common across Chester County. Around West Chester, PA it marks property lines, frames stone farmhouses and meets front-yard rules that require open fencing, since it is mostly air. Add welded wire mesh to keep a dog in. It defines space rather than providing privacy or security.
Drive out Route 52 or along the Brandywine and split rail is everywhere: in front of eighteenth-century stone farmhouses, along subdivision entrances, edging horse pastures and running beside lanes. Around West Chester, PA it remains the default fence for anyone who wants to mark a boundary without closing off a view. It is also one of the more forgiving fences in the township codes, because it is low and almost entirely open.
Why is split rail so common around West Chester, PA?
Because it fits the landscape and the rules at the same time. The rails are rough-split wood set into mortised posts, so the fence reads as agricultural and old, which suits farmhouses and battlefield-era properties in Birmingham, Thornbury and East Bradford.
It also works where codes require open fences. West Goshen limits front-yard fences to 4 feet with at least as much open area as structure; Westtown allows 5 feet in the front setback for open fences; East Whiteland requires at least 50 percent open. A typical two- or three-rail fence is well under those limits. Uwchlan’s 36-inch front-yard cap is tighter, so rail height matters there. See front-yard fences.
Two rails or three?
Two-rail split rail sits around 3 feet tall and is mainly decorative: corners, driveways, garden borders. Three-rail stands closer to 4 feet and is the better choice for perimeter lines, pastures and anywhere you will add wire mesh.
Both use the same mortised posts with no nails or brackets; the rails sit in the post holes and can be replaced one at a time when one finally rots. Typical 76 FENCE guidance for wood is 15 to 20 years.

Can a split rail fence keep a dog in?
Yes, with welded wire mesh attached to the inside face. The mesh is nearly invisible from a distance, so the fence keeps its open look while the dog stays put.
Black mesh hides better than galvanized. For a dog that jumps, three-rail with mesh is the minimum, and a true jumper may need a taller fence behind the house. Compare options on our dog fence page and the wire mesh material page.
Is split rail a good fence near a creek?
It is one of the better choices when a fence is allowed at all, because it is open and less likely to trap debris than a solid fence. That said, East Bradford and Chadds Ford prohibit new construction within 50 feet of the top of a stream bank, and floodways restrict fences that can catch flood debris.
A common approach along the Brandywine is a split rail line set back at the buffer edge with native plantings between the fence and the water. It marks the boundary without fighting the creek. Read fences near streams before planning a line near water.
| Use | Recommended setup |
|---|---|
| Front yard or driveway accent | Two-rail, no mesh |
| Property line on acreage | Three-rail |
| Dog containment | Three-rail with black welded wire mesh |
| Creek-side boundary | Three-rail set back at the buffer edge |
| Horse pasture | Three-rail or board; see horse fencing |
Does split rail need a permit?
In many places, yes. West Goshen requires a zoning permit for every fence regardless of height, Thornbury and Pocopson require one for any fence, and Westtown requires one for fences over 40 feet of total length, which most split rail lines exceed. East Bradford only requires a permit above 6 feet. Thornbury also requires fences to sit at least 6 inches off the property line unless the neighbor agrees in writing. Details are in the permit guide.
Cedar or pressure-treated rails?
Split rail is traditionally made from naturally rot-resistant wood, and the rough-split texture weathers to gray within a few seasons. Pressure-treated posts can extend life at ground level where moisture sits. We bring samples so you can see how each will age.
How does split rail handle slopes and rock?
Better than most fences. Rails follow the ground naturally, so rolling Chester County lots do not need stepped panels. Rock in the post holes, common in the schist uplands, is the bigger challenge; our crew carries tools for it. See rocky soil and fence posts.
Long rail runs across open ground usually cross a utility line somewhere, so the PA One Call ticket matters here, and we place it along with any HOA forms. Rules change, so confirm with the township; when you hire us, we pull the permit. Call or text 484-999-0965 to walk the line with us. For pasture fencing, see horse and farm fences.
