Short answer
Lower Gwynedd Township caps fences and walls at 6 ft in any yard its zoning code requires, and every yard facing a street counts as a front yard on a corner lot. Fences need a permit: the township’s checklist asks for two copies of a scaled plan showing property lines, setbacks, structures, the driveway and trees 6 in or wider within 50 ft of the work. Pools deeper than 3 ft need a 4 to 6 ft fence with a self-locking gate.
| Rule | What the code says |
|---|---|
| Front yard | No separate front-yard height found; the 6 ft cap applies to every required yard. We confirm front-yard practice with the township. |
| Side and rear yards | Up to 6 ft. |
| Corner lots | All yards abutting a street are treated as front yards. |
| Sight lines | No wall, fence or structure may obstruct vision at street intersections or crosswalks; plantings there limited to 3 ft. |
| Sports courts | Fences up to 6 ft around sports courts and up to 10 ft around tennis courts (amended 2026). |
| Pools | Pools able to hold more than 3 ft of water: fully fenced, 4 to 6 ft high, nonremovable, self-locking gate. |
| Placement and materials | No finished-side, setback, easement or material rules found. |
| Permit | Required. Application with zoning section, contractor license application and two scaled plans. |

What the permit checklist asks for
Lower Gwynedd’s Building and Zoning department publishes a fencing checklist, and it’s specific. It warns that incomplete submissions delay the permit and that more detail is better than less. Expect to provide:
- The permit application with the zoning section filled in, plus the contractor license application.
- Two copies of a plan drawn at 1 in = 20 ft or larger.
- Property lines and their dimensions, and the required setback lines.
- Distances from the fence to buildings and other structures, and the driveway location.
- Every tree 6 in or more in diameter within 50 ft of the work.
On an older lot with mature trees, that can be a long list, so we measure and mark each qualifying tree when we draw the plan. Questions go to Building and Zoning at (215) 646-5302.
Horse country rules
Lower Gwynedd takes in Gwynedd, Gwynedd Valley, Penllyn and Spring House and is known as an equestrian community, with large lots and about 20 miles of trails. The township code requires horse grazing areas to be fenced so the horses stay contained at all times. That’s a containment standard, not a style, so board, post-and-rail and wire-backed fences can all work. The 6 ft cap still applies in required yards. Our split rail and farm fence page covers the common options.
Creeks and floodplain
Lower Gwynedd lies in the Wissahickon Creek watershed. A published copy of Lower Gwynedd’s Floodplain Conservation District chapter (Ch. 1290) doesn’t list fences as a permitted use, prohibits freestanding structures, bars removing trees or vegetation within 20 ft of a stream bank, and calls for a DEP permit for work within 50 ft of the top of bank. If your lot touches a stream, we confirm with the township before planning any fence near it.
Pools in Lower Gwynedd
Any pool that can hold water deeper than 3 ft must be fully fenced. The fence must be at least 4 ft and no more than 6 ft high, nonremovable, built so children and stray animals can’t get through or under it, and fitted with a self-locking gate. An above-ground pool’s walls count as the fence if they’re at least 4 ft high, as long as the ladder or steps are guarded by a compliant fence and gate or the pool has a self-raising safety ladder. The pool permit drawings must show the fence.
Addresses in Lower Gwynedd
Homes with Gwynedd (19436), Gwynedd Valley (19437) and Spring House (19477) addresses are in Lower Gwynedd, along with many Ambler (19002) addresses and some in Blue Bell and North Wales. The township is in the Wissahickon School District. See our Gwynedd and Spring House page and the Ambler page.
What we haven’t confirmed
- A separate front-yard height. The code’s 6 ft cap is written for all required yards, and we ask the township how it applies out front.
- The permit fee.
- Any finished-side, setback, easement or material rule.
- The floodplain chapter details above come from a code-publisher copy, not the township’s own site.

Common questions
How tall can a fence be in Lower Gwynedd?
Up to 6 ft in any yard the zoning code requires. The code doesn’t set a lower front-yard number, but corner lots treat every street side as a front yard, so we confirm the front-yard approach with the township.
Does Lower Gwynedd need a tree survey for a fence permit?
The fencing checklist asks for every tree 6 in or more in diameter within 50 ft of the work to be shown on the plan.
Do I need a fence around my horse pasture in Lower Gwynedd?
Yes. The township code requires horse grazing areas to be fenced to contain the horses at all times.
