Waltham's Animal Ordinances: The Rules That Matter
Every city handles animal ordinances a little differently. In Waltham, Massachusetts, there are 7 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Wildlife Feeding
Waltham discourages wildlife feeding to prevent conflicts with bears, coyotes, and turkeys increasingly seen near Prospect Hill and the Cambridge Reservoir.
Key details: State Rule: 321 CMR 2.14. Bear Feeding: Prohibited statewide. Coyote Hotspots: Prospect Hill, Charles River. Bird Feeders: Allowed generally. Enforcement: MassWildlife + local.
Contact your local code enforcement office for specific penalty information.
Exotic Pets
Massachusetts maintains one of the strictest exotic pet lists in the country, and Waltham follows state rules prohibiting most wild and dangerous animals.
Key details: State Rule: 321 CMR 9.01. Prohibited: Primates, big cats, venomous. Allowed: Standard pets only. Agency: MassWildlife. Max Fine: 500 dollars.
Contact your local code enforcement office for specific penalty information.
This is not one of those rules that cities tend to ignore. Waltham actively enforces its exotic pets requirements.
Livestock
Waltham is a dense suburban city with very limited agricultural zoning, so traditional livestock like cattle, horses, and pigs are essentially prohibited.
Key details: Minimum Lot: 2+ acres agricultural. Horses: Agricultural zones only. Hens Exception: Most residential zones. Right to Farm: MGL c.40A s.3. Manure Rules: Health Department.
Contact your local code enforcement office for specific penalty information.
Compared to other cities, Waltham takes a harder line on livestock. The enforcement and penalty structure reflects that.
Breed Restrictions
Massachusetts state law prohibits breed-specific legislation, so Waltham cannot ban pit bulls or any breed, but dangerous dog rules apply regardless of breed.
Key details: State BSL Ban: MGL c.140 s.157A. Local Bans: Prohibited by state. Dangerous Dog: Based on behavior. Remedies: Muzzle, enclosure, insurance. Hearing Body: Animal control hearing.
Contact your local code enforcement office for specific penalty information.
The rules around breed restrictions in Waltham lean permissive, but that does not mean anything goes.
Chickens & Livestock
Waltham zoning allows backyard chickens in limited residential districts with setback requirements, but no roosters and no other livestock.
Key details: Hens Allowed: Up to 6 in Residence A. Roosters: Prohibited citywide. Coop Setback: 10 ft property line. Dwelling Setback: 25 ft from neighbor. Livestock Minimum: 2 acres agricultural.

If you are coming from a city with tighter rules, you will find Waltham gives residents more flexibility on beekeeping.
