Fence height rules in Mashpee, Massachusetts
Mashpee's bylaws don't set a general fence height limit; the zoning bylaw is silent on ordinary fences. The Building Department lists a permit for fences over 8 feet, but the state building code exempts only fences up to 7 feet, so ask the Building Department before building anything over 7 feet. On corner lots, nothing over 2.5 feet is allowed in the 20-foot sight triangle, and extra review applies in the Historic District and near wetlands.
| General height limit | None found in the zoning or general bylaws (fences aren't 'buildings') [1] |
| Building permit | Town FAQ: fences over 8 ft (state code exempts only up to 7 ft; confirm for 7-8 ft fences) [2] |
| Corner-lot sight triangle | Max 2.5 ft within 20 ft of the street-line intersection [3] |
| Historic District, front of building (2009/2011 design guideline) | Guideline: open and low, not over 42 in; certificate required [5] |
| Fences in the wetland buffer strip | Bottom at least 1.5 ft above grade; must not block wildlife [6] |
No general height limit
Mashpee's zoning bylaw excludes fences from the definition of a "building" [1], and neither the zoning bylaw nor the general bylaws set a height limit or property-line setback for an ordinary residential fence. The Building Department lists "fences over 8 feet in height" among the projects that need a permit [2], so most backyard fences need no building permit. The state building code, though, exempts only fences up to 7 feet, so a fence between 7 and 8 feet may still need a permit; confirm with the Building Department before building one. The state's 6-foot spite-fence law still applies between neighbors.
Corner lots
On any corner lot, in all districts, no fence, wall, hedge or other visual obstruction may be taller than 2.5 feet above street grade inside the triangle formed by the street lines 20 feet from where they meet [3].
Historic District
Inside the Mashpee Historic District, a fence counts as a "structure," and you need a certificate from the Historic District Commission before building one that is visible from a public way [4]. The Commission's design manual is older guidance (2009, revised 2011) and may have been updated; it says fences in front of a building should be open and low, not over 42 inches, and that chain link is prohibited; more solid, taller fences belong where they're less visible from the street [5].
Near wetlands and the shore
Fences inside the Naturally Vegetated Buffer Strip may be allowed by the Conservation Commission if they don't block wildlife movement, public access between high and low water, or cause erosion; the bottom should be at least 1.5 feet above grade [6]. Replacing an existing fence by hand, with no new post holes, generally needs no formal wetlands application [7]. New fences within 150 feet of a wetland resource area fall under the local wetlands bylaw.
Pool fences
General Bylaw §153-1 requires every private outdoor pool to be fenced to the State Building Code [8]. That is a pool-barrier rule, not a general fence rule (see the Pools page). A fence also can't block the area between the street and a fire hydrant (§46-1).

- If the fence will be over 7 ft, ask the Building Department (508-539-1400 ext. 8556) whether you need a building permit (the town lists permits for fences over 8 ft; the state code exempts only up to 7 ft) and apply through PermitEyes if so.
- In the Historic District, apply to the Historic District Commission for a certificate before building.
- Within 150 ft of a wetland, pond or the shore, check with the Conservation Commission before installing new posts.

Massachusetts state rules on fences
Most fence rules in Massachusetts are local, set in your town's zoning bylaw and sometimes historic-district rules. A few state laws apply everywhere:
- Building permit: the State Building Code (780 CMR, 10th edition) does not require a building permit for fences 7 feet high or less. Taller fences need one. Zoning height limits and setbacks still apply, and many towns cap fences at 6 feet.
- Spite fences: under M.G.L. c. 49, §21, a fence that unnecessarily exceeds 6 feet and is maliciously put up or kept to annoy a neighbor is a private nuisance. The neighbor can sue for damages.
- Fence viewers: every town must appoint fence viewers each year (c. 49, §1). Where adjoining owners both enclose and use their land, they share the upkeep of the partition fence equally unless they agree otherwise. If one side won't repair their share, the other can complain to the fence viewers, who can order the repair (c. 49, §§3–4). By statute, a "legal and sufficient" fence is 4 feet high and in good repair (c. 49, §2).
- Pool fences must meet the state pool barrier rules (see Pools).
- Wetlands: fence work in a wetland or within 100 feet of one may need Conservation Commission review.
