Overview: Massachusetts Backyard Chicken Laws: Permit Requirements, Flock Limits, and Rooster Bans
Massachusetts maintains a notably progressive stance toward urban agriculture, and backyard chickens benefit from this policy orientation.
The statewide constitutional amendment Article 97 (Right to Farm) provides foundational protections for agricultural activities.
Massachusetts General Laws Chapter 111, Section 125A authorizes the Department of Agricultural Resources (MDAR) to regulate poultry health.
However, just as in most New England states, the actual authority to allow or restrict backyard chickens lies with the 351 cities and towns through their local boards of health and zoning bylaws.
Boston, through its Article 89 Urban Agriculture Ordinance adopted in 2013, explicitly permits up to 6 hens (no roosters) with a permit, making it one of the more permissive major East Coast cities.
Cambridge, Somerville, Worcester, and Amherst have similarly progressive ordinances.
The City of Boston's Inspectional Services Department enforces these regulations, requiring annual permit renewal and coop inspection.
A notable feature of Boston's law is the explicit prohibition of on-site slaughter.
On the other end of the spectrum, some suburban communities with dense populations and small lot sizes, such as Brookline, Newton, and Wellesley, impose stricter requirements including larger lot size minimums (often 1+ acre), greater coop setbacks (up to 50 feet), and mandatory neighbor notification or consent.
Some towns require a special permit from the Zoning Board of Appeals, which involves a public hearing process.
A unique feature of Massachusetts law is the strong role of local Boards of Health.
Under M.G.L.
Chapter 111, Section 31, Boards of Health can issue regulations to protect public health, and they can order the removal of animals (including chickens) deemed a nuisance or health hazard.
This power operates independently of zoning regulations.
Did You Know?
Did you know? Massachusetts is one of the more permissive states for backyard chickens. Local city ordinances often have more impact on your ability to keep chickens than state-level laws.
State Law Analysis: Massachusetts
Massachusetts General Laws Chapter 111, Section 125A serves as the primary state-level statutory authority for poultry regulation.
This statute grants MDAR broad powers to control contagious diseases among poultry, including quarantine authority and mandatory testing during disease outbreaks.
All poultry keepers--regardless of flock size or commercial status--are subject to MDAR disease control orders.
The Massachusetts Right to Farm amendment (Article 97 of the state constitution) and M.G.L.
Chapter 61A provide protections for agricultural land, including tax benefits and limitations on nuisance actions.
However, Massachusetts courts have consistently held that these protections apply primarily to operations in areas zoned for agriculture, not necessarily to small-scale backyard flocks in residential neighborhoods.
See Shea v.
Board of Health of Hampden, 85 Mass.
App.
Ct. 110 (2014).
M.G.L.
Chapter 40A, the Zoning Act, grants municipalities authority to regulate land use through zoning bylaws, which is the primary mechanism by which Massachusetts cities and towns control backyard chicken keeping.
The interplay between Board of Health regulations and zoning bylaws creates a two-tier regulatory system that chicken owners must navigate.
