Short answer: A deer fence in West Chester, PA should generally be 8 feet tall; conservation guidance puts exclusion fencing at 8 to 12 feet. Most nearby townships cap residential side and rear fences at 6 feet, so a full 8-foot fence may need a permit, a building permit or relief from zoning. Fencing just the garden is often the simpler route.
Anyone who gardens in West Chester, PA knows the routine: tulips gone overnight, arborvitae browsed into lollipops, vegetable beds trimmed at a perfect deer height. A fence is the most reliable fix, but only if it is tall enough, and tall fences run straight into township height limits. This page sorts out both.
How many deer are there in Chester County?
A lot more than the land can carry. The WeConservePA deer management handbook reported that Pennsylvania averaged about 30 deer per forested square mile in 2007, three to six times the desired 5 to 10. In suburban areas, densities can exceed 100 per square mile.
Chester County Parks runs archery deer management programs in 11 county parks, a sign of how persistent the pressure is. For homeowners, this means deer are not occasional visitors; they are a standing condition.
- Effective height: 8 feet is the practical target; guidance cites 8 to 12 feet for exclusion fencing.
- Typical township cap: 6 feet in residential side and rear yards.
- Deer density: about 30 per forested square mile statewide (2007); over 100 in some suburbs.
- Common workaround: enclose the garden or orchard rather than the whole lot.

Why does a deer fence need to be 8 feet?
Because a white-tailed deer can clear a 6-foot fence when it is motivated. A standard privacy-height fence slows deer and blocks sight lines, but it will not reliably keep a hungry herd out of a garden in February. WeConservePA’s handbook states that deer exclusion fencing “should be 8–12 feet high.”
Ways to make a fence deer-resistant
- Full height. A 7.5 to 8 foot poly or steel mesh fence on posts around the garden or orchard.
- Double fence. Two shorter fences a few feet apart; deer are reluctant to jump into a narrow gap.
- Angled fence. A fence leaning outward makes the jump harder to judge.
- Tight bottom. Deer will push under loose mesh, so the base needs to be pinned or tensioned.
Can you put up an 8-foot deer fence in your township?
Sometimes, with extra steps. Each municipality writes its own rules, and several around West Chester cap fences at 6 feet. Here is what the codes we reviewed say, at the time of writing:
| Municipality | What the code says about height |
|---|---|
| West Goshen | Zoning permit for every fence; 6 ft in residential side and rear yards; building permit at 8 ft and above. |
| Westtown | 6 ft outside the front setback area, with decorative post tops to 7 ft (§ 170-1505). |
| Thornbury (Chester Co.) | 6 ft maximum in any residential yard; permit for any fence. |
| East Bradford | No height cap stated; fences over 6 ft need a building permit and engineered plans. |
| West Whiteland (Exton) | 6 ft in required yards; above 6 ft must be at least 50% non-opaque; 12 ft absolute maximum (§ 325-29). |
Notice the pattern. In West Whiteland, an open mesh deer fence may fit the rule because the part above 6 feet is see-through. In East Bradford, height is possible but requires engineered plans. In Thornbury, 6 feet is the limit unless relief is granted. Your township may treat agricultural or garden enclosures differently; ask before you buy materials.
What materials work for deer fencing?
Most deer fences use mesh rather than solid panels, since a wall of mesh is cheaper, lets wind through and nearly disappears from a distance.
Poly mesh
Light and nearly invisible in black. Good for gardens; less resistant to chewing animals.
Welded or woven wire
Stronger and longer-lived, on wood or steel posts. See wire mesh fencing.
Mesh on split rail
Keeps a rural look but stays low; useful for pets, not deer on its own. See split rail.
Which West Chester areas see the most deer pressure?
Do deer fences need gates?
Yes, and the gate is usually the weak point. A deer fence is only as good as its lowest, loosest opening, so the gate should match the fence height and close tightly at the bottom. For a garden, a single walk gate wide enough for a wheelbarrow is typical; for an orchard or field, a double gate that fits a mower or small tractor saves frustration later. Self-closing hinges help when family members forget to latch it.
Lots that back up to woods, stream corridors and preserved land see the heaviest browsing: the Brandywine valley in East Bradford and Pocopson, wooded parts of Westtown, and estate areas near the battlefield. Borough yards see deer too, especially near parks and creek corridors.
