Fence height rules in Manchester-by-the-Sea, Massachusetts
Manchester-by-the-Sea's Zoning By-law sets no fence height limit or property-line setback for homes, because fences aren't counted as 'structures'. Near wetlands, fencing is a permitted 'minor activity' in the buffer zone as long as it doesn't block wildlife movement. Pools must be enclosed by a fence at least 4 feet high.
| Max height (front, side, rear) | No zoning limit found; fences aren't 'structures' [1] |
| Setback from property line | None in zoning [1] |
| Wetlands buffer zone | Allowed as a minor activity if it isn't a barrier to wildlife movement [2] |
| Pool fence | At least 4 ft [4] |
| Fences on site-plan-review projects | Up to 6 ft with plantings, Planning Board approval [5] |
Fences aren't structures under zoning
The Zoning By-law's definition of "structure" expressly excludes walls and fences [1]. Setbacks and height limits in the bylaw apply to buildings and structures, so the April 2026 compilation we reviewed sets no front, side or rear fence height limit for a house lot and no minimum distance from the property line. We found no corner-lot sight-line rule for fences, and the bylaws don't say which side must face out.
Near wetlands and the water
Manchester's wetlands regulations allow fencing in the Resource Area Buffer Zone as a "minor activity," provided it won't block wildlife movement [2]. A minor activity is permitted in the buffer zone or Riverfront Area only if it isn't inside another resource area such as the wetland itself, a bank or a beach [3]. A fence within the wetland or on a coastal bank needs Conservation Commission review. The regulations' definition of "structure" includes fences for wetlands purposes, so ask the Conservation Commission before building close to a resource area.
Pools
The General By-laws require a fence at least 4 feet high around every private swimming pool [4]. The state pool barrier rules (48-inch barrier, self-closing gates) also apply.
Larger developments
Projects under Planning Board site plan review may have fencing up to 6 feet with plantings. Half the length of fences facing a public way must be softened with plantings, and the Planning Board approves the design [5]. This doesn't apply to ordinary home fences.
Floodplain
Fences in the floodplain overlay district count as development the floodplain rules regulate, so check with the Building Department if your lot is in a flood zone.

- Check with the Building Department (978-526-2010) if your lot is in the flood zone or Historic District, or if the fence will be over 7 feet (state building permit).
- For a pool, install a fence at least 4 feet high that meets the state barrier rules.

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.
