Published: Last updated:

In Massachusetts, keeping an emotional support animal is a housing question, decided as a reasonable-accommodation request under the federal Fair Housing Act and M.G.L. c. 151B, § 4. Since May 22, 2026, HUD reviews requests for untrained ESAs case by case, so Massachusetts's own rules below matter.

Massachusetts ESA FAQ

Do I need to register my emotional support animal in Massachusetts?

No. Neither federal nor Massachusetts law requires or recognizes ESA registration.

What does Massachusetts require in an ESA letter?

Massachusetts has no ESA-specific letter law, so general fair housing rules apply under M.G.L. c. 151B, § 4.

Can my landlord in Massachusetts refuse my ESA or charge a pet fee?

The landlord must consider it as a reasonable-accommodation request under M.G.L. c. 151B, § 4 and the federal Fair Housing Act. Since May 2026, HUD no longer treats untrained ESAs as presumptively reasonable, so the outcome depends on your facts and Massachusetts law. If it's granted, ask in writing whether pet fees or deposits are waived.

Can I take my ESA into stores or restaurants in Massachusetts?

No. Mass. Gen. Laws ch. 272, § 98A and the ADA give access rights to trained service dogs only.

Can I fly with my ESA from Boston Logan (BOS)?

Airlines at Boston Logan (BOS) may treat an ESA as a pet under 14 CFR Part 382, so check your airline's pet rules before booking.

Where can I file a housing complaint in Massachusetts?

With the Massachusetts Commission Against Discrimination (MCAD) within 300 days of the incident, or with HUD within 1 year. Private Fair Housing Act lawsuits can be filed within 2 years.
