Pet Deposits, Pet Rent & ESA Rules in Maryland 2026
State pet-deposit treatment, federal Fair Housing Act assistance-animal rules, and what Maryland landlords can and cannot ask.
Maryland has no pet-specific landlord statute, so your pet policy is governed by two separate legal tracks that landlords routinely confuse. Ordinary pets are a matter of contract, limited only by the state security-deposit cap. Service animals and emotional support animals are a matter of disability law under the federal Fair Housing Act and the parallel Maryland Fair Housing Law (State Government §20-701 et seq.), where the animal is legally not a pet at all. Treating an assistance animal like a pet, by charging a fee or applying a breed ban, is the single most common way Maryland landlords trigger a fair-housing complaint.
How Maryland Treats Pet Deposits
Security deposit capped at 2 months' rent. Pet deposits count toward this cap; Maryland law does not authorize a separate pet deposit allowance.
Ordinary pets: what you can charge in Maryland
For pets that are not assistance animals, Maryland leaves pet rent, pet fees, and pet deposits to the lease. There is no state cap on pet rent or a monthly pet fee, and no statute forbidding them. The one hard limit is the security deposit.
Under Real Property §8-203, a landlord may collect a security deposit of no more than one month’s rent for any lease signed on or after October 1, 2024 (the prior cap was two months). Critically, the statute defines “security deposit” broadly to cover any money held against damage, so a pet deposit or damage deposit counts toward that one-month cap, it is not a separate bucket. A $1,800 base deposit plus a $500 pet deposit on an $1,800/month unit is over the limit.
A narrow exception allows up to two months’ rent only where the tenant qualifies for Department of Human Services utility assistance, pays utilities directly to the landlord, and both sides agree in writing. Overcharge the deposit and the tenant can recover up to three times the excess plus attorney’s fees, in an action brought during the tenancy or within two years after it ends. Structure a refundable pet deposit inside the one-month total, and take non-refundable pet rent as a monthly line item instead.
Service animals vs. emotional support animals
The two categories are not interchangeable, and the difference controls what you may ask.
A service animal under the ADA is a dog (or in limited cases a miniature horse) individually trained to perform work or a task tied to a disability, guiding, alerting to seizures, retrieving. Comfort alone does not qualify a service animal under the ADA.
An emotional support animal provides therapeutic benefit through its presence without task training. ESAs do not qualify as ADA service animals, which is why they have no guaranteed access to stores or restaurants. But in housing, the Fair Housing Act uses the broader term “assistance animal,” which covers both trained service animals and ESAs. For a Maryland rental, both are handled the same way: as a reasonable accommodation, not as a pet.
No pet fees for assistance animals, and the two questions you may ask
Because an assistance animal is not a pet, you may not charge a pet deposit, pet rent, or pet fee for a service animal or ESA, and you may not apply a “no pets” clause to one. Requiring any of these is a failure to make a reasonable accommodation under the FHA. The tenant does remain fully liable for actual damage the animal causes, which you can deduct from the ordinary deposit or pursue like any other tenant damage.
When a disability and the need for the animal are obvious, you may ask for nothing further. When they are not obvious, federal guidance limits you to exactly two questions: (1) does the person have a disability, and (2) is there a disability-related need for the animal? You may request supporting documentation only for the second, non-obvious case, and you must respond to the request promptly. An unreasonable delay can itself be treated as a denial.
Documentation: what counts and what you can reject
Maryland has no ESA-letter registration statute, so the federal reliability standard governs. A legitimate ESA letter comes from a licensed health-care or mental-health professional with a genuine therapeutic relationship with the tenant. That letter need only establish the disability and the disability-related need, it does not have to name a diagnosis.
You are not required to accept documentation that is facially unreliable. Instant online “ESA registrations,” printable “certificates,” and vendor letters from a provider who has never evaluated the tenant carry no legal weight, and you may ask for verification tied to an actual clinical relationship. Reject the paperwork, not the accommodation: the safe move is to request reliable documentation, not to deny the animal outright.
When you can lawfully deny, and breed or size limits
Breed bans, weight caps, and one-pet limits in your lease do not apply to assistance animals. You cannot deny a pit bull ESA on breed alone. A denial has to rest on the specific animal, not its category: evidence that this animal poses a direct threat to the health or safety of others, or would cause substantial physical damage that cannot be reduced by another accommodation. A documented bite history or repeated aggression can support denial; a breed reputation cannot.
Enforcement in Maryland runs through the Maryland Commission on Civil Rights under the state fair-housing law, alongside HUD under the federal FHA. Federal civil penalties escalate with repeat violations, reaching into the tens of thousands of dollars, on top of the tenant’s actual damages and attorney’s fees. Given that exposure, document every accommodation request, your response, and the basis for any denial in writing.
The Cost of Mishandling a Maryland ESA Request
The most common mistake in Maryland ESA cases is responding with a flat denial, "no pets means no pets", instead of engaging in the interactive process. The interactive process is itself a substantive duty. A landlord who refuses to consider the request, demands more documentation than HUD permits, or imposes a pet fee on an accepted assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied on its merits.

Related Guides for Maryland Landlords
This guide reflects Maryland Real Property §8-203 (security deposits, one-month cap effective October 1, 2024), the Maryland Fair Housing Law at State Government §20-701 et seq. enforced by the Maryland Commission on Civil Rights, the federal Fair Housing Act, and ADA service-animal rules. It is written for landlords and is general information, not legal advice; confirm current statutory text and consult counsel before denying an accommodation, since a wrongful denial carries federal penalties plus damages and attorney’s fees.
Frequently Asked Questions
Can a Maryland landlord charge a pet deposit for an emotional support animal?
No. An ESA is treated as an assistance animal, not a pet, under the Fair Housing Act, so you may not charge a pet deposit, pet rent, or pet fee for it. You can still hold the tenant responsible for any actual damage the animal causes, deducted like any other tenant damage.
Does a pet deposit count toward Maryland's security deposit cap?
Yes. Real Property §8-203 defines security deposit broadly, so a pet or damage deposit counts toward the same cap, which is one month's rent for leases signed on or after October 1, 2024. A base deposit plus a pet deposit cannot exceed that combined limit.
What can I ask when a tenant requests an assistance animal?
If the disability and the need are obvious, nothing. If they are not obvious, you may ask only two things: whether the person has a disability, and whether there is a disability-related need for the animal. You may request supporting documentation only in that non-obvious case.
Can I reject an online ESA certificate or registration?
You do not have to accept facially unreliable documentation. Instant online registrations and printable certificates carry no legal weight. Ask for a letter from a licensed professional with a genuine therapeutic relationship with the tenant rather than denying the animal outright.
Do my breed or weight restrictions apply to a service animal or ESA?
No. Breed bans, weight caps, and pet limits do not apply to assistance animals. You may deny a specific animal only on evidence that it poses a direct threat or would cause substantial damage, not based on its breed or your general pet policy.
Does Maryland have a pet-specific landlord law?
No. Maryland has no statute setting pet rent, pet fees, or pet deposit amounts for ordinary pets, so those terms are contractual and limited only by the §8-203 security-deposit cap. Service and emotional support animals are governed by the federal Fair Housing Act and the Maryland Fair Housing Law instead.
