Pets are everywhere in Boston rentals these days. Walk through any neighborhood, and you'll see dog walkers, cat owners chatting on stoops, and even a few guinea pigs staring out from apartment windows. If you're a landlord, this shift matters. Pet ownership is rising, and prospective tenants often filter their search by one thing first: is this place pet-friendly?
That's why pet policies matter so much right now. A clear, fair policy protects your rental property. It also keeps pet owners happy and reduces tenant challenges down the road. Let's break down what Boston landlords actually need to know.
Let this blog help you set rules that work for your rental, your tenants, and their furry friends.
Key Takeaways
- Massachusetts law caps the traditional security deposit at one month's rent, so pet deposits and pet rent need to be structured carefully and separately.
- Emotional support animals and service animals are not pets under the Fair Housing Act, and you cannot charge fees or apply breed restrictions to them.
- Breed, size, and weight restrictions should line up with your renters insurance and pet liability insurance requirements, not just personal preference.
- A written pet addendum protects everyone involved and should cover pet waste, noise, house training, and what counts as property damage versus normal wear and tear.
Why Pet-Friendly Rentals Make Sense
No pet policies used to be the default. Landlords worried about property damage, noise, and liability. But times have changed. Pet-friendly apartments now rent faster and often command higher monthly rent. Allowing pets broadens your pool of applicants.
Of course, going pet friendly doesn't mean skipping structure. You still need pet rules that protect your property and other tenants living in the building.
Pet Fees, Pet Rent, and Deposits: What's Actually Legal in Massachusetts
This is where many landlords get confused, so let's slow down.
The Traditional Security Deposit Limit
Massachusetts law caps the traditional security deposit at one month's rent. That's a hard limit. You can't tack on extra fees and call it a general security deposit if it pushes the total past the one-month-rent threshold.
Where Pet Deposits and Pet Rent Fit In
So where does a pet deposit fit in? Many landlords treat a pet security deposit separately from the general security deposit. Some charge a specified pet deposit upfront. Others prefer a monthly pet fee, sometimes called pet rent, which is a recurring charge added to the base rent.
The Non-Refundable Fee Gray Area
Here's the catch. Massachusetts law doesn't clearly bless non-refundable pet fees the way some other states do. If you charge pet fees, be careful about labeling anything as truly non-refundable. Talk to a local attorney before you finalize your numbers. State and local law can shift, and local ordinances in Boston may add extra layers on top of Massachusetts law.
Bottom line: you can typically charge pet rent or a pet deposit, but always check current local law before setting your fee structure.
Figuring out the right numbers can feel like a guessing game, especially with Massachusetts law changing how deposits work. Platinum Realty Group helps Boston landlords set pet fees and deposits that stay compliant while still covering their costs.

Emotional Support Animals and Service Animals Are Not Pets
This next part trips up even experienced property managers. Emotional support animals and service animals are not legally considered pets, and they fall under different rules entirely.
The Fair Housing Act requires landlords to make reasonable accommodations for tenants with a disability who need an assistance animal, including emotional support animals, service animals, and other companion animals. A tenant with a legitimate need for such animals cannot be charged pet fees, a monthly pet fee, or any additional fees tied to pet ownership.
You also can't apply your usual breed restrictions or weight limits to assistance animals. You can ask for documentation supporting the need for the accommodation, but you can't demand medical records or question the tenant about their disability. Getting this wrong exposes you to real legal risk.
Setting Breed, Size, and Weight Restrictions
For regular pets, you have more flexibility than you do with assistance animals. Many landlords stick to common household pets like cats, small dogs, and guinea pigs, then set clear breed or size restrictions for anything larger. Certain breeds, including pit bulls, sometimes get labeled as dangerous breeds by insurers or local ordinances, so it helps to know where you stand before writing anything into your lease.
A few things to check before you finalize your restrictions:
- Review your renters insurance policy and any pet liability insurance requirements, since some insurers won't cover certain dog breeds at all.
- Confirm your breed restrictions actually match what your insurer allows, not just what you personally prefer.
- Set weight limits based on your actual property. A 25-pound cutoff might make sense for a small apartment building but feel unnecessary for a spacious rental unit.
- Keep your restrictions consistent across every lease so no applicant feels unfairly targeted.
Building a Solid Pet Addendum
A verbal agreement about pets won't hold up when something goes wrong. You need a written pet addendum attached to your lease agreement.
A good pet agreement should cover the basics: a pet resume with age, temperament, and vaccination history, confirmation the pet is house trained, and clear expectations around pet waste and excessive noise. It should also spell out what happens with unauthorized pets, since tenants sometimes bring home a new companion animal without asking first.
Don't bury this in fine print. Tenants should understand the pet rules before they sign, not after a dispute comes up.
Protecting Your Property and Other Tenants
Pet damage is a real concern, but there's a difference between property damage and normal wear and tear. A few scratches on an old floor is wear and tear. A chewed doorframe or stained carpet is property damage, and your lease should say so directly.
Make it clear who covers repair costs. Many landlords use the pet deposit for cleaning and minor repairs, then charge extra fees for anything beyond that, keeping things fair while protecting you from a tenant's mess becoming your financial problem.
Also consider other tenants in the building. Pet amenities like a dog run or wash station are a nice touch, but only if paired with rules that keep pets well-behaved around neighbors.
Best Practices for Property Managers
If you manage multiple properties, consistency matters more than people think. A pet policy that varies from building to building creates confusion for tenants and invites fair housing complaints. The fix is simple: document everything, apply it consistently every time, and revisit it on a regular schedule.
A few habits make this easier to maintain:
- Keep your pet policies written down and attached to every rental agreement, not just explained verbally during a showing.
- Apply the same pet rules across all your properties so no tenant feels singled out.
- Review local laws and ordinances at least once a year, since Boston's rules can change with little warning.
- Train any staff or leasing agents on how to handle assistance animal requests correctly, since mistakes here carry real legal risk.
- Keep a simple log of pet-related incidents or complaints so patterns show up early rather than becoming bigger tenant challenges later.
Frequently Asked Questions
Q1: Can a landlord limit how many pets a tenant has?
Yes. Most landlords cap it at one or two pets per unit. Just write the limit into your pet agreement, and remember it doesn't apply to assistance animals.
Q2: Can a landlord add a no-pet clause partway through an existing lease?
Not usually. A lease is binding, so new pet rules should wait until renewal, with written notice given in advance.
Q3: What about tenants who pet-sit or have visiting pets?
Cover this in your pet addendum. Decide if visiting pets need approval, and set a time limit, like anything over a week counts as a pet.
