Massachusetts Pet Limit Laws: How Many Pets Can You Own?

There is no statewide number in Massachusetts that limits how many pets you can own. The practical limits come from city and county codes, kennel and breeder licenses, and your lease or homeowners association.

Massachusetts pet limit rules at a glance

What Massachusetts law says

• A personal kennel is more than 4 dogs 3 months or older (s. 136A).
• Kennels are inspected at least once a year, and the authority sets the maximum number of animals (s. 137C).
• Owners of fewer dogs may choose a kennel license instead of individual licenses.

Where pet limits usually come from

• City and county ordinances. Cities can cap household pets or require a kennel or multi-pet permit above a set number.
• Zoning rules. Keeping many animals can turn a home into a "kennel" use that is not allowed in residential zones.
• Leases and HOAs. Landlords and homeowners associations can set lower limits than the law, and many restrict size or breed.
• Nuisance and cruelty laws. Even without a number cap, barking, odor or poor care can lead to enforcement.

How to check the limit for your address

1. Search your city code for "animals" or "dogs" and look for a number limit or a kennel permit section.
2. If you live in an unincorporated area, check the county code instead.
3. Read your lease or HOA covenants.
4. Ask local animal services; they also sell dog licenses and can tell you whether a multi-dog or kennel license is needed.

Thinking about adding another pet? Local shelters and rescues can tell you what the adoption process involves; see how adopting a dog or cat works.
