Fence height rules in Sudbury, Massachusetts
Sudbury's Zoning Bylaw lets you put fences and gates in any yard, including the front yard, with no setback from the property line. The 2023 bylaw we reviewed sets no specific fence height limit, so check with the Building Department before building a tall fence.
| Where fences may go | Any yard (front, side or rear); no setback stated [1] |
| Max height | No specific fence height found; fences are 'subject to height limitations' [1] |
| Flood Plain Overlay | Fences allowed if accessory to a single-residence use and they don't affect watercourse flow [2] |
| Pool enclosures | Must meet the State Building Code [3] |
Fences are allowed in any yard
Sudbury has no stand-alone fence bylaw. The Zoning Bylaw's definition of "Yard" lists fences and gates among the items that "are permitted in any yard but shall be subject to height limitations" [1]. That means a fence doesn't have to meet the building setbacks and can go up to the lot line, including in the front yard. On a corner lot, both street sides count as front yards.
Height
The bylaw doesn't say what height limit applies to fences. We found no fence-specific height cap, front-yard limit, corner sight-line rule, or "good side out" requirement in the 2023 Zoning or General Bylaws. Under the State Building Code, a fence over 7 feet needs a building permit, and a fence over 6 feet put up to annoy a neighbor can be a spite fence under state law. Confirm any local height rule with the Building Department before building.
Special situations
- Flood plain: In the Flood Plain Overlay District, where most structures are banned, fences are still allowed if they're accessory to a single-residence use and don't affect the natural flow of any watercourse [2].
- Pools: Pool enclosures must meet State Building Code barrier rules [3].
- Wetlands: A fence within 100 feet of a wetland may need Conservation Commission review under Sudbury's Wetlands Administration Bylaw.
- Historic districts: Sudbury has several local historic districts, whose rules aren't covered here.
About our sources
We reviewed the 2023 town PDF of the Zoning Bylaw. The current codification (zoning effective May 2025) is only on eCode360, which we couldn't access, so a later fence amendment can't be ruled out.

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.
