# ESA Letter in Waltham, MA: No Local Office, Same Rights

> Waltham has no fair housing commission of its own. The state agency needs no local office to act, and the request you write is what starts the duty running.

## Key facts

- Population: 65,849
- Households renting: 50.3%
- Typical pet deposit (as a pet): Varies by building
- Typical pet rent (as a pet): Varies by building
- Breed/weight limits common: yes
- Pet fees, deposits, and breed limits with a valid ESA letter: none (FHA reasonable accommodation)

## Half the city rents, and half of it does not

Waltham has 25,498 occupied homes, and 12,828 of them are rented, 50.3%,
against a statewide 37.5% on the 2020-2024 American Community Survey five-
year estimate.

An almost even split produces an unusual mix of landlords. Managed buildings
with written policies sit alongside converted houses let by owners who may
handle one tenancy at a time. A tenant asking for an accommodation may be
writing to a property manager or to a person who has never had the question
put to them before.

## Nothing local, and why that is not a problem

Research of the city's own website did not surface a municipal body that
receives and decides housing discrimination complaints. That is reported as
a search result, not as a conclusion about the city.

Either way, the absence changes nothing about your rights. The Massachusetts
Commission Against Discrimination takes complaints from anywhere in the
Commonwealth without any municipal involvement, and its nearest office to
Waltham is its Boston headquarters at 1 Ashburton Place. HUD is a parallel
federal route.

Filing needs no lawyer, no fee and no trip.

## The sentence your request rests on

Massachusetts has no emotional support animal statute. The duty is general,
at M.G.L. c. 151B § 4(7A)(2), which makes it discrimination to refuse

> "reasonable accommodations in rules, policies, practices, or services, when
> such accommodations may be necessary to afford a handicapped person equal
> opportunity to use and enjoy a dwelling."

Animals entered that duty through the state's enforcement agency rather than
the legislature. In 2024 the MCAD Full Commission adopted assistance animal
as covering animals "whether such animals are trained or untrained", and
held that they must be accommodated absent undue hardship.

## Ask for the exception, in writing, once

The most common mistake is a verbal request that later cannot be proved.

Write it. Name the clause: the weight limit, the no-animals term, the one-
pet cap. Say that you have a disability and that the animal is necessary for
you to use and enjoy the apartment. Attach the letter from the professional
who treats you. Date it, and send it in a way that leaves a record.

MCAD's position is that "it is the initial request for an accommodation
which triggers the obligation to participate in the interactive process."
The date you asked is the date the landlord's duty began, which is worth
being able to prove.

## Documentation, and its ceiling

Where the disability or the need is not obvious, the provider may ask for
reliable documentation of the disability-related need.

A letter from someone who treats you, connecting the condition to what the
animal does, meets that. Your diagnosis does not have to be named, your
records do not have to be produced, and there is no Massachusetts
certificate to buy, the Office on Disability warns that "a letter or
certificate bought from a website after a short interview is not considered
sufficient documentation."

## Weight caps and breed schedules

Managed buildings publish numbers. For an approved assistance animal those
numbers do not apply: the state's disability office states that providers
"cannot impose breed/weight restrictions or pet-fees/deposits/insurance
requirements".

What survives is the conduct of your particular animal, assessed
individually. An animal that has injured someone or damaged property can be
judged on that record; a breed cannot be judged in advance.

## The money rules, kept in order

Up front, M.G.L. c. 186 § 15B(1)(b) permits "rent for the first full month
of occupancy", "rent for the last full month of occupancy calculated at the
same rate as the first month", "a security deposit equal to the first
month's rent" and "the purchase and installation cost for a key and lock". A
pet deposit is unlawful for every tenant in Waltham, disability or not.

Monthly, the deposit statute has nothing to say, so the accommodation duty
does the work for an approved assistance animal.

And § 15B(7)'s treble damages attach to different clauses than the one an
unlawful move-in charge trips, which is worth knowing before demanding three
times anything.

## The exemption, and how narrow it is

M.G.L. c. 151B § 4(7) does not reach the leasing of a single apartment in an
owner-occupied two-family dwelling. That is the whole exemption, and in a
city of converted houses it is worth quoting precisely.

A three-family is covered. A landlord living elsewhere is covered. And under
804 CMR 2.01(4) the exemption disappears where the tenant receives public
assistance or a rental subsidy, where a real estate professional was used,
or where the advertising was discriminatory.

## Two provisions that get quoted at the wrong time

Landlords and tenants alike find two Massachusetts statutes when they search
for animals and disability, and neither belongs in a housing conversation.

M.G.L. c. 272 § 98A concerns dog guides in places of public accommodation,
sits among the criminal provisions and carries a $300 penalty. It is about
being refused entry to a shop or a restaurant.

M.G.L. c. 272 § 85B is the only Massachusetts statute using the phrase
assistance animal, and it is a theft and attack provision limited to a
physically impaired person and a trained animal. It punishes harm to an
animal; it does not define who may keep one at home.

If either turns up in a refusal letter, the reply is that the housing duty
is in c. 151B, and that is the chapter the request was made under.

## Three deadlines, one of which is easy to lose

MCAD: 300 days from the conduct, under 804 CMR 1.04(3), running from when
you "knew or should have known of the claim of discrimination".

HUD: one year.

Court: under M.G.L. c. 151B § 9, three years if you filed with the
Commission first and one year if you did not. Housing claims require no
exhaustion, so the shorter deadline is available to anyone who skips the
free filing without knowing what it protects.

## Free help west of Boston

MetroWest Legal Services covers Waltham within its service area and handles
housing matters for low income residents. It is the appropriate regional
programme for this city.

For a public housing tenancy, the state's local housing authority contact
listing carries the Waltham Housing Authority's verified address and
telephone number, and the animal question in state-aided housing is
governed by 760 CMR 6.03 read together with Public Housing Notice 2023-01,
which directs authorities to process assistance animals as reasonable
accommodations rather than under a pet policy.

## When the reply is a refusal

Ask for the refusal in writing and ask what ground it rests on. There are
only two: undue hardship, evidenced, or the conduct of your specific animal.

A landlord who names neither has given you the clearest evidence available.
Take it, with your dated request and the supporting letter, to MCAD, and do
it while the 300 days are young rather than while they are ending.

One more thing worth doing before you file, particularly with a small
landlord who may simply be uncertain. Send a short follow-up offering to
answer questions about what the accommodation would involve in practice:
where the animal sleeps, who cleans up after it, what happens if a neighbour
complains. None of that is legally required of you. It occasionally converts
a refusal born of unfamiliarity into an approval, and it costs one email. If
it does not work, the follow-up joins the file as evidence that you engaged
in the interactive process even when the landlord did not.

## What Waltham landlords can and cannot do

**Cannot:**
- Cannot refuse to make a reasonable accommodation in rules, policies, practices or services where it may be necessary to afford a handicapped person equal opportunity to use and enjoy a dwelling: M.G.L. c. 151B § 4(7A)(2).
- Cannot refuse to rent to someone because they will need an accommodation, which makes the rejection of an applicant who discloses an animal unlawful in its own right, M.G.L. c. 151B § 4(7A)(3).
- Cannot demand a pet deposit or an up-front pet fee from any tenant, disabled or not: M.G.L. c. 186 § 15B(1)(b) closes the list of move-in charges to "rent for the first full month of occupancy", "rent for the last full month of occupancy calculated at the same rate as the first month", "a security deposit equal to the first month's rent" and "the purchase and installation cost for a key and lock".
- Cannot take a security deposit larger than one month's rent, whatever the animal is, M.G.L. c. 186 § 15B(1)(b)(iii).
- Cannot insist the animal be trained. MCAD's Full Commission adopted "assistance animal" as covering animals "whether such animals are trained or untrained", and upheld a claim where the hearing officer expressly found the dog was not a trained service animal.
- Cannot deny a request solely because the animal does not meet the federal ADA definition of a service animal, MCAD's press statement of 31 July 2026 says such a denial "may be in violation of Massachusetts law".
- Cannot treat HUD's withdrawal of its federal assistance-animal guidance as shrinking state protection; MCAD states the federal changes "do not modify or limit the protections provided under Massachusetts law".
- Cannot require magic words. MCAD applies the rule that a request need only be made "in a manner that a reasonable person could understand it to be a request for an exception, change, or adjustment to a rule, policy, practice or service because of a disability".
- Cannot skip the interactive process: MCAD holds that "it is the initial request for an accommodation which triggers the obligation to participate", and found a landlord liable who never asked what help the animal gave or for any documentation.
- Cannot charge for an assistance animal by another name: the Massachusetts Office on Disability states that assistance animals "are not considered pets, so housing providers cannot impose breed/weight restrictions or pet-fees/deposits/insurance requirements".
- Cannot rely on a species or weight cap as an answer in itself; MCAD's test asks only whether the animal's presence is reasonably necessary to afford the tenant an equal opportunity to use or enjoy the premises.

**Can:**
- May ask for supporting documentation from a medical provider who treats the tenant, where the disability or the disability-related need is not obvious.
- May refuse where the animal would be a direct threat to the health or safety of others, where the accommodation would be a fundamental alteration of operations, or where it would impose an undue burden.
- May enforce lease terms unrelated to the accommodation, and may hold a tenant liable for actual damage the animal causes.
- May decline entirely in an owner-occupied two-family dwelling, since M.G.L. c. 151B § 4(7) does not reach it, but 804 CMR 2.01(4) takes that exemption away where the tenant receives public assistance or a rental subsidy, where a real estate professional is used, or where the advertising is discriminatory.
- May, in state-aided public housing, apply pet policies to actual pets, but EOHLC's PHN 2023-01 directs local housing authorities to handle assistance animals through the reasonable accommodation process instead.

## Frequently asked questions

### Is there a Waltham office that handles housing discrimination complaints?

None surfaced in research of the city's own website, which is reported as a search result rather than as a finding about the city. The routes that certainly work are the Massachusetts Commission Against Discrimination, within 300 days of the conduct under 804 CMR 1.04(3), and HUD, within one year. Neither requires a local office, a lawyer or a fee, and MCAD's nearest location to Waltham is its Boston headquarters at 1 Ashburton Place.

### My building has a written pet policy with a weight limit. Where do I start?

With a written request for an exception to that specific limit. M.G.L. c. 151B § 4(7A)(2) makes refusing a reasonable accommodation in rules or policies discrimination where the accommodation may be necessary for a handicapped person to use and enjoy a dwelling, and the Office on Disability states that assistance animals "are not considered pets, so housing providers cannot impose breed/weight restrictions". Attach the supporting letter with the request rather than promising it later.

### Does it matter that my animal has no formal training?

No. The MCAD Full Commission held in 2024 that assistance animals include animals "whether such animals are trained or untrained" and that untrained animals which assist a person with a disability must be accommodated absent undue hardship. The Commission also dismissed as "hyperbolic" the argument that this permits any animal to qualify by default. Training belongs to the service animal analysis in a different area of law, and a housing provider applying it is applying the wrong test.

### What is the landlord entitled to see?

Where the disability or the disability-related need is not obvious, reliable documentation of that need, a letter from a professional who treats you connecting your condition to what the animal does. Not a diagnosis, not records, not a certificate. The Massachusetts Office on Disability warns that a letter or certificate bought from a website after a short interview is not sufficient documentation, so the treating relationship is what makes the letter useful.

### Can a monthly pet fee be charged if the animal is approved?

Not for an approved assistance animal. The state's disability guidance says providers cannot impose pet fees, deposits or insurance requirements on assistance animals, and the accommodation duty is what carries that into a monthly charge. The up-front version fails for a different and simpler reason: M.G.L. c. 186 § 15B(1)(b) permits only four charges at or before the start of a tenancy, and a pet charge is not among them for any tenant.

### Who provides free legal help in Waltham?

MetroWest Legal Services covers Waltham as part of its service area west of Boston and takes housing matters for low income residents. MCAD accepts complaints directly with no fee. If the tenancy is public housing, the state's local housing authority contact listing carries the Waltham Housing Authority's verified address and telephone number, which is more reliable than a search result.

### How do the deadlines interact if I want to sue later?

File with MCAD first. Under M.G.L. c. 151B § 9 a person who filed with the Commission has three years to bring a civil action, while a person who went straight to court has one, and housing claims carry no exhaustion requirement to force the issue either way. MCAD's own filing window is 300 days from the conduct, running from when you knew or should have known of the claim, so the free filing both preserves the agency route and protects the longer court deadline.
