Short answer: Pennsylvania has no statewide fence setback from a property line, so in West Chester, PA it comes down to your township. East Bradford, Chadds Ford and Kennett allow a fence on the line, Thornbury requires at least 6 inches off unless your neighbor agrees in writing, and front-yard setbacks from the road are stricter in Westtown and East Whiteland.
“How close can I build?” is the question behind most neighbor disputes about fences, and the answer in Chester County is set locally, not in Harrisburg. That leaves two separate questions: what your township allows, and where your line actually is. This page covers the first and points to our survey guide for the second.
- State law: no general statewide setback for residential fences; municipalities set the rules.
- On the line allowed: East Bradford, Chadds Ford (§ 135-196A(3), residential zones), Kennett (allowed but discouraged).
- Off the line required: Thornbury, at least 6 inches and wholly on the owner’s property, unless the neighbor agrees in writing.
- Road side: West Goshen and East Bradford keep fences out of the right-of-way; Westtown requires 10 ft from the future right-of-way in front; East Whiteland none within 10 ft of the front lot line.
How close to the property line can you put a fence in PA?
As close as your municipality allows, which ranges from directly on the line to a few inches off, with larger setbacks along the road.
Because there is no single state number, two homes on either side of a township boundary can follow different rules. The table summarizes what we found for municipalities around West Chester. Where a township’s fence section was not retrieved, we list it as unconfirmed rather than guess.
| Municipality | Side and rear lot lines | Along the street |
|---|---|---|
| East Bradford | Fence may sit on the property line | Out of the road right-of-way and sight lines |
| Chadds Ford | On the lot line allowed in residential zones (§ 135-196A(3)) | Check with township |
| Kennett Twp | On the line allowed, but discouraged | Front fence 4 ft max |
| Thornbury (Chester Co.) | At least 6 in off, wholly on your land, unless neighbor agrees in writing | 6 ft max in any yard |
| Westtown | Not stated in the sections reviewed | At least 10 ft from the future right-of-way |

Can you build a fence right on the property line?
In some townships you legally can, but it creates shared-ownership questions, so we usually recommend setting the fence slightly inside your own line.
A fence straddling the line sits partly on your neighbor’s land. That raises questions about who owns it, who repairs it, and who decides when it is replaced. Building a few inches inside your line keeps the fence clearly yours. The trade-off is a narrow strip of your yard on the outside of the fence, which you still own and should be able to reach for upkeep. If you and your neighbor want a true shared fence on the line, put the agreement in writing, as Thornbury’s rule anticipates.
The line is not where the old fence is
Hedges, old fences and mowing lines drift over decades. On older lots in the borough and on farm parcels out toward the Brandywine, the visible boundary and the deeded boundary can differ by more than people expect. Before setting posts near a line, find the corner pins or have them reset by a Pennsylvania-licensed land surveyor.

What can you do if a neighbor’s fence is on your property?
Start by confirming the line with a survey, then talk with your neighbor. If that does not resolve it, consult a real-estate attorney.
A survey turns a disagreement about opinions into a disagreement about a measurement, which is easier to settle. Many encroachments are a few inches and end with a written agreement or with the fence being moved when it is next replaced. Long-standing encroachments can carry legal consequences that depend on the facts, which is why an attorney, not a fence contractor, should advise on them. Pennsylvania’s old partition-fence law is sometimes raised in these conversations; our fence viewers explainer covers what it does and does not do.
Do township setbacks apply to replacement fences?
Usually, yes. A new fence generally has to meet today’s code, even if the old one stood in a different spot.
Westtown, for example, requires a permit for installing or replacing fences over 40 feet long. A replacement is a good time to correct an old fence that strayed over the line or crowded the right-of-way. See fence replacement for how we handle tear-out, and do you need a survey before a fence for finding your pins. For attached homes, read shared fences for twins and rowhomes; for orientation rules, read which side faces the neighbor. Township specifics are on our Thornbury, East Bradford and Chadds Ford pages.
