Where hens are allowed

Henkeeping is an allowed accessory use under the Zoning Ordinance when done on a residential lot (and on religious and educational properties), as long as it meets the urban agriculture standards in Article 23 [1]. You need a permit from the Cambridge Public Health Department [1], and only hens may be kept; roosters aren't allowed [3].

How many

No more than six hens may be kept on a lot unless your health department permit explicitly authorizes more, and never more than twelve [2].

Coop and run rules

Hens must be kept in an enclosure made up of a henhouse and a hen run. The enclosure must be at least 5 feet from any property line, or closer if a solid wall, fence or similar opaque barrier screens it from the neighbor [4], and it can't be in a front yard [5]. A freestanding henhouse can be no taller than 8 feet and cover no more than 50 square feet [6]. The health regulation also requires enclosures to be at least 100 feet from a wetland [7], to drain onto your own lot, and to provide at least 2 sq ft of henhouse floor and 4 sq ft of run per hen. Henhouses and hen runs that meet Article 23 may sit in required yards.

Applying

The application includes a drawing of the lot showing the henhouse, run, existing structures and distances to neighboring lots; manure and pest management plans; the number of hens; the property owner's signed consent; and evidence that you notified all adjacent lot owners. The fee is $50, renewal is $25 [8], and permits expire each April 30 and must be renewed annually, with at least one routine inspection a year [9].

Eggs and other animals

Selling cooked or processed egg products needs a retail food permit from ISD. Neither document we reviewed allows other livestock such as ducks or goats.

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).
