Do You Need a Survey Before a Fence in West Chester, PA?

Townships around West Chester typically ask for a plot plan with a fence permit, not a fresh survey. But a plot plan drawn from an old plat is only as accurate as the markers on the ground. Here is how to decide whether you need a surveyor, what you might already have, and what it is likely to cost.

• Who surveys: a Pennsylvania-licensed professional land surveyor; a fence contractor cannot certify a boundary.
• Cost reference: HomeGuide lists property surveys at roughly $200 to $1,200 nationally; local quotes vary with lot size and records.
• Permit paperwork: Uwchlan and Kennett ask for a plot plan showing the fence location.
• When it matters most: fences on or near the line, Thornbury’s 6-inch rule, front setbacks of 10 ft in Westtown and East Whiteland.

Do you need a survey before installing a fence?

Not by state law, and usually not by township rule, but you need to know where the line is, and a survey is the reliable way to know it.

If your fence will sit well inside your lot, with an obvious margin from every boundary, existing markers and a plat are often enough. If you plan to build on or close to the line, if the corner pins are missing, or if a neighbor disputes the boundary, a survey is worth the cost. It is far cheaper than moving a finished fence. The same applies when a township measures a setback from the line, such as Thornbury’s requirement that a fence stand at least 6 inches off the line unless the neighbor agrees in writing.

What you may already have

Check your closing documents for a plot plan or survey drawing, and look up the recorded subdivision plan for newer neighborhoods in West Goshen, Westtown or Uwchlan. Then walk the lot for iron pins or monuments at the corners; a metal detector helps. Older borough lots and farm parcels may have descriptions written in metes and bounds, with markers that were lost long ago.

How do you know whether your survey is good enough?

Use this checklist. If you can tick every item, you can probably lay out the fence without a new survey.

• You have a drawing that shows lot dimensions and the house location.
• You can find physical markers at the corners the fence will approach.
• The distances between found markers match the drawing.
• Your neighbor agrees on where the line is.
• The fence will stay comfortably inside the line, not on it.

If any item fails, call a surveyor before the fence crew. When markers have been disturbed by landscaping, driveway work or an old fence removal, ask the surveyor to reset them and flag the line for the install.

How much does a property survey cost in Chester County?

HomeGuide’s national figures put a property survey at roughly $200 to $1,200. A local surveyor will quote based on your lot and how much research the records need.

Small subdivision lots with recent recorded plans tend to be simpler than old farm parcels or borough lots with historic deed descriptions. Ask whether the quote includes setting missing pins and staking the line, since that is what the fence crew actually uses. Survey costs are separate from the fence itself; for fence pricing context, see our fence cost guide.

On larger properties, the survey does more than settle a boundary. Long pasture or estate runs magnify small angle errors over hundreds of feet, and lots along the Brandywine may include creek frontage where East Bradford and Chadds Ford bar new construction within 50 feet of the top of the bank. A surveyor can show the bank line and any easements on the same drawing, so the fence plan respects all of them at once.

How does the survey fit into the fence process?

It comes first, before the permit drawing and before the PA One Call request.

1. Locate the line. Found pins, or a surveyor’s stakes.
2. Walk the layout. At our free estimate, 76 FENCE West Chester measures from the markers and agrees the fence line with you.
3. File the permit. The plot plan shows the fence relative to the line and the road.
4. Mark utilities. We request PA One Call before digging; see calling 811 before a fence.
5. Install. Posts go in to a string line pulled from the stakes.

Can the fence company find your property line for you?

We can measure from markers you have found and from your plan, but we cannot certify a boundary. Only a licensed surveyor can.

That distinction matters if the line is ever disputed. For township setback rules, read how close to the property line a fence can go, and for attached homes, shared fences for twins and rowhomes. If you are in Thornbury or Uwchlan, see those pages for local permit details, and our fence installation page for how the build goes.

Rules change, so confirm with the township — when you hire us, we pull the permit once the line is settled.
