Fence height rules in Carlisle, Massachusetts
Carlisle has no fence bylaw, so there's no local height limit for side or rear fences. Zoning keeps any structure taller than 5 feet out of the front setback (40 feet from the street in residential districts); treating a fence as a "structure" is how we read the bylaw, so confirm with the Building Department. At street corners, nothing between 3 and 7 feet high may block visibility within 6 feet of the street lines and 20 feet of the intersection.
| Structures over 5 ft near the street | Must meet the building setback (40 ft in residential districts) [1] |
| Front setback, residential districts | 40 ft from the street line [2] |
| Corner visibility zone | No obstruction 3-7 ft above road crown [3] |
| Corner zone extent | Within 6 ft of street lot lines and 20 ft of the intersection [4] |
| Side and rear fences | No local height limit or setback found [5] |
Height near the street
Carlisle's Zoning Bylaw doesn't regulate fences by name. However, Section 4.2.2 says that, other than flags and utility or light poles, no structure over 5 feet high may be closer to a street than the setback required for a building on the same lot [1]. In General Residence Districts A and B that building setback is 40 feet from the street line (measured from 20 feet off the centerline on narrow roads) [2]. In practice, a fence or wall of 5 feet or less can go along the front lot line, while a taller fence has to stay 40 feet back.
Corner lots
The General Bylaws prohibit any fence, wall, structure, vegetation or other object that impedes visibility at street intersections [3]. The restricted zone is the space 3 to 7 feet above the road crown, within 6 feet of the street lot lines, and within 20 feet of where the street lot lines meet [4]. Existing stone walls, mailboxes, utility poles and trees with no branches below 7 feet are exempt.
Side and rear yards
The side and rear setbacks in Section 4.3 apply to buildings [5], and we found no separate height limit or setback for fences along side or rear lot lines. Massachusetts law still applies: fences over 7 feet need a building permit, and a fence over 6 feet put up maliciously to annoy a neighbor can be a spite-fence nuisance.
Other reviews
Pool barriers must meet state code, fences in or within 100 feet of wetlands may need Conservation Commission review, and work in the Historic District that affects exterior features may need Historical Commission approval.

Next steps
- Measure your planned fence's distance from the street line; if it's over 5 ft tall, keep it at least 40 ft back.
- On a corner lot, keep the area within 20 ft of the intersection and 6 ft of the street lines clear between 3 and 7 ft high.
- Call the Building Department (978-369-6689) to confirm no permit is needed (fences over 7 ft require one) and whether your lot is in the Historic District.
- If the fence is near a wetland, stream or pond, check with the Conservation Commission before installing it.

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.
