Can I keep backyard chickens in Acton, Massachusetts?
We found no rule on backyard chickens in Acton's Zoning Bylaw, General Bylaws or Board of Health regulations (2022 version): no hen limit, rooster ban, coop setback or poultry permit. The Board of Health's animal rules cover only horses and stables, and zoning's farm protection is limited to commercial agriculture on parcels of 2 acres or more.
| Backyard hen rule | None found in zoning, general bylaws or Board of Health regulations [1] |

No backyard poultry rule
We found no Acton rule that says whether you can keep hens at home, how many, whether roosters are allowed, how far a coop must be from the lot line, or whether you need a permit. That covers the Zoning Bylaw (May 2026), the General Bylaws (September 2026) and the Board of Health Rules and Regulations (2022 version).
What the Board of Health regulates
Article 12 of the Board of Health regulations is titled "Keeping of Animals (Farm) and Domestic Pets," but its rules address horses only. No one may keep a horse without an approved stable [1]. A stable needs a Board of Health permit, and none is issued for a lot under 2 acres [2]. The article also covers manure handling. It says nothing about chickens or other poultry.
Zoning
The Zoning Bylaw lists agriculture, including keeping or raising livestock as a commercial enterprise, as a general use. It limits those uses to parcels of 2 acres or more, following state law (M.G.L. c. 40A, §3) [3]. A small backyard flock kept for eggs isn't described anywhere in the bylaw. A coop would still be a structure subject to zoning setbacks (see Sheds).
Right to Farm
Acton's Right to Farm bylaw recognizes farming done under generally accepted agricultural practices, including the noise and odors that come with it [4]. It doesn't create a separate permit or set hen limits.
What still applies
The general Animal Control bylaw bars letting any animal go at large to the injury or nuisance of others [5], so birds need to stay on your property. State rules, such as the annual census of livestock and poultry, still apply (see the state section). A Board of Health policy or permit outside the written regulations we reviewed is possible. Because the town's documents are silent, ask the Health Department before you get birds.

Massachusetts state rules on backyard poultry
Massachusetts has no statewide right to keep backyard hens. Whether you can keep chickens, how many, and where the coop goes are set locally, through your town's zoning bylaw and Board of Health regulations.
- Board of Health power: under M.G.L. c. 111, §31, local boards of health may adopt "reasonable health regulations", and many use this power to require a permit to keep poultry. Violations can bring fines of up to $1,000. In towns with an agricultural commission, the board must send that commission any proposed rule affecting the non-commercial keeping of poultry, livestock or bees for a 45-day review.
- Agricultural zoning protection is for farms, not most backyards: c. 40A, §3 stops zoning from banning or requiring a special permit for commercial agriculture. Towns may limit that protection to parcels of 5 acres or more, or 2 acres or more if the land produces at least $1,000 per acre a year in sales. A typical backyard flock doesn't qualify.
- Annual barn inspections: your town's animal inspector, working under the state Department of Agricultural Resources (MDAR), does annual barn inspections and a census of livestock and poultry. Backyard flock owners may be contacted.
- Nuisance rules still apply: a board of health may also regulate or prohibit an activity that causes a nuisance or offensive odors (c. 111, §143).
