Frequently Asked Questions: Massachusetts Pet Addendum

Can a landlord charge a pet deposit in Massachusetts?

Yes, landlords in Massachusetts can charge a pet deposit. However, total deposits (security + pets) must comply with Massachusetts's limit of 1 month rent. Note that pet deposits cannot be charged for service animals or emotional support animals.

Can a landlord refuse pets in Massachusetts?

Yes, landlords in Massachusetts can generally refuse pets or set restrictions. However, they cannot refuse service animals or emotional support animals under the Fair Housing Act. Breed-specific restrictions may also be subject to local laws.

What is the difference between a pet deposit and pet rent?
