Can You Have Pets in Delaware Apartments? A Renter’s Legal Guide

If you’re searching for a place to live in Wilmington, Dover, or Rehoboth Beach and you own a dog, cat, or something more unusual, you’ve probably wondered whether Delaware law gives you any protection when a landlord says no. The short answer is that Delaware gives landlords a lot of freedom to set their own pet rules, but that freedom has real limits once deposits, disabilities, and lease terms come into play.

This guide walks through what Delaware’s Residential Landlord-Tenant Code actually says about pets, what you can be charged, and what happens if your landlord tries to change the rules after you’ve already moved in with your animal.

Important Note: This article explains general Delaware landlord-tenant law for informational purposes and is not a substitute for legal advice. If you’re facing a specific dispute, consider contacting the Community Legal Aid Society of Delaware or a licensed attorney.

Can a Landlord Ban Pets in Delaware

Yes, a Delaware landlord can legally ban pets entirely, and there’s no state statute forcing them to accept animals. While landlords can choose whether to accept pets, they must adhere to any legal requirements, but the code does not provide specific regulations for allowing or prohibiting pets, instead focusing on the maintenance and operation of the property.

In practice, that means the Delaware Residential Landlord-Tenant Code is largely silent on pet ownership itself. No state law mandates that a landlord accept pets, except for assistance animals, so landlords set the rules on breed restrictions, size limits, and the number of pets allowed. Whatever policy a landlord chooses, those rules must be clearly spelled out in the lease agreement for them to hold up if a disagreement ever ends up in court.

This is why reading your lease before you sign it matters more in Delaware than in states with stricter pet-friendly mandates. If you already have a dog or cat, ask the property manager directly rather than assuming an apartment complex’s marketing photos of happy pets mean every unit is pet-friendly. Some buildings allow pets only in certain units or only below a certain floor.

Pro Tip: Get any verbal promise about pet approval in writing as a lease addendum. Delaware courts rely on the written rental agreement when pet disputes arise, not verbal assurances from a leasing agent.

Pet Deposits and Pet Fees: What Delaware Allows

Delaware is one of the few states that actually caps how much a landlord can charge for a pet, which is a detail many renters miss. Under Delaware law, no landlord may require a pet deposit in excess of one month’s rent, regardless of the duration of the rental agreement. This deposit is meant to cover pet-related damage rather than serve as extra profit for the landlord.

Beyond the pet deposit itself, landlords have room to charge other fees. Landlords are permitted to charge pet fees to tenants who wish to keep pets, and these fees can include a one-time pet deposit, monthly pet rent, or a combination of both. There’s no statewide dollar limit on pet fees, but they must be reasonable and not excessive.

Application fees follow a separate, more specific rule. A landlord may charge an application fee not to exceed the greater of either 10 percent of the monthly rent or 50 dollars, used to determine a tenant’s creditworthiness. If a landlord charges more than that, Delaware law gives you recourse.

Charge Type	Delaware Legal Cap	Refundable?
Security Deposit (lease of 1+ year)	1 month’s rent	Yes, minus damages
Pet Deposit	1 month’s rent	Yes, minus pet-related damage
Application Fee	Greater of 10% of rent or $50	No
Pet Rent / Monthly Pet Fee	No statutory cap; must be reasonable	No

When you do move out, the clock starts ticking on your refund. Delaware landlords must return security deposits within 20 days of move-out, along with an itemized statement showing any deductions. That same 20-day rule applies to your pet deposit, since it’s treated under the same statutory section as your regular security deposit.

If you’re weighing whether a particular animal is worth the added deposit, it helps to think about what actually causes property damage. Chewed baseboards and scratched flooring drive most pet-deposit deductions, which is one reason some renters look at low-maintenance pets that pose less risk to a rental unit’s finishes.

Breed and Weight Restrictions in Delaware

Because the state landlord-tenant code doesn’t regulate breed or size at all, this is entirely a matter of individual lease terms. Landlords determine breed restrictions, size limits, and the number of pets on their own, since no state law addresses these details. That means one Wilmington apartment complex might ban dogs over 40 pounds while a building two blocks away has no weight limit whatsoever.

Common restrictions you’ll encounter in Delaware leases include:

• Breed exclusions for dogs commonly flagged by insurance carriers, such as pit bull-type breeds, Rottweilers, and Doberman Pinschers
• Weight limits, often set between 25 and 50 pounds per animal
• Caps on the total number of pets per unit, typically one or two
• Exotic animal bans covering reptiles, certain rodents, or venomous species

These restrictions typically apply per building or management company rather than citywide, so a rejection at one property doesn’t mean every landlord in the area will say no. If a breed restriction rules out a dog, some renters look at smaller companion animals instead, including rabbit breeds, chameleons, or even insects kept as pets, which rarely trigger breed or weight clauses at all.

Key Insight: Breed and weight restrictions cannot be applied to a legitimate service animal or emotional support animal, even in a lease that otherwise bans certain breeds. Landlords cannot deny reasonable accommodation requests based solely on pet restrictions or breed preferences when a tenant has valid documentation.

Worth noting: some animals that seem like appealing low-maintenance options actually create more liability than owners expect, whether through noise complaints, escape risk, or damage potential. Before choosing a pet for apartment living, it’s worth reviewing which species tend to cause landlords the most headaches, since a quick look at commonly flagged difficult pets can save you a rejected application later.

Service Animals and Emotional Support Animals: Your Rights in Delaware

This is where Delaware law shifts from “landlord’s choice” to genuine tenant protection. Under the federal Fair Housing Act and Delaware’s Fair Housing Law (Del. Code tit. 16, § 4603A(a)(2)), landlords must make reasonable accommodations for tenants or applicants with disabilities and verified emotional support animals, even in buildings with no-pet policies.

Fees work differently here too. Landlords are prohibited from charging extra pet-related fees or deposits when presented with a valid ESA letter confirming the animal’s therapeutic necessity. The same protection extends to service animals under the standard security deposit statute: tenants with service animals are exempt from paying the additional pet deposit fee but remain liable for any damages the animal causes.

Landlords aren’t required to say yes in every case. A landlord may deny a request only if the animal poses a safety risk, causes significant damage, or would create an undue burden. On the documentation side, a housing provider can ask for a letter from a health care provider verifying the disability and need for the assistance animal, but only if the disability isn’t apparent, so a landlord can ask about an emotional support cat but can’t demand proof from a blind tenant needing a guide dog.

Delaware also has a law specific to guide dogs. Delaware’s White Cane Law requires landlords to allow guide dogs in rental housing for tenants who are fully or partially blind, and a landlord can’t charge extra for the guide dog, though the tenant can be required to pay for any damage it causes. That particular statute doesn’t extend to other types of service dogs or emotional support animals, which is why the broader Fair Housing Law and federal FHA end up doing most of the work for other assistance animals.

If you and your no-pet-policy landlord disagree about a reasonable accommodation, keep every communication in writing and hold onto a copy of your documentation. This is one area of Delaware rental law where getting it wrong can mean a fair housing complaint, not just a lease dispute.

Can a Landlord Change the Pet Policy Mid-Lease in Delaware

Once you’re locked into a fixed-term lease, your landlord generally can’t rewrite the pet policy on you overnight. During the agreement term, a landlord may not change the rental amount, but with at least 60 days’ notice, the landlord may change the rental amount and any other provision in the agreement for the next rental period. That “any other provision” language covers pet policies, deposit amounts, and similar lease terms.

You’re not powerless when that notice arrives, either. The tenant has the opportunity to reject the changes in the revised agreement for the next lease term if the rejection happens within 45 days, and this rejection is treated as an effective termination notice; if the tenant doesn’t reject the terms in time, the new terms are understood to be accepted.

Month-to-month arrangements work a bit differently, since there’s no fixed term to protect during. Landlords can usually modify terms from one month to the next, again with proper notice, and Delaware law requires at least 60 days’ written notice before a rental agreement expires if the landlord plans to renew with changes, with the tenant given 45 days after that notice to object to the proposed terms.

Pro Tip: If your landlord suddenly announces a new no-pet policy mid-lease without the required notice period, that change likely isn’t enforceable against you for the remainder of your current term. Document the date you received notice and compare it against your lease’s end date.

None of this changes your obligations under the lease you already signed. If your original agreement never mentioned pets and you added an animal without asking, a new pet addendum introduced mid-lease could still apply to you going forward, even if it wouldn’t apply retroactively to force you to remove the pet immediately.

What to Do If Your Landlord Won’t Allow Your Pet in Delaware

Before assuming you have no options, work through these steps in order:

1. Re-read your lease. Confirm whether the pet ban is explicit or just an assumption based on the listing description.
2. Ask if a reasonable accommodation applies. If your animal qualifies as a service animal or emotional support animal, the no-pets clause legally does not apply to you under Fair Housing protections.
3. Negotiate a pet addendum. Some landlords will allow a pet for an added deposit (capped at one month’s rent) even if the standard lease says no pets.
4. Request documentation of the denial in writing. This creates a paper trail if you later need to dispute the decision.
5. Contact a tenant resource organization. The Delaware State Housing Authority and Delaware Community Legal Aid Society provide plain-language summaries of tenant rights and can point you toward the right next step.
6. Consider Justice of the Peace Court for deposit disputes. If a dispute involves money already paid, such as a wrongly withheld pet deposit, you can sue for the full deposit amount plus court costs and attorney fees in Delaware Justice of the Peace Court.

If your landlord’s refusal seems tied to your pet’s breed rather than a disability accommodation, your leverage is more limited, since breed restrictions in a standard pet-optional lease are generally enforceable. In that situation, it’s often faster to find a different unit than to fight the restriction, especially in a competitive rental market. If you’re reconsidering what pet fits your living situation, smaller options like pet crabs, pet snails, or pet scorpions rarely run into weight or breed clauses at all, though you should always confirm exotic-animal policies before bringing one home.

Whatever pet you end up keeping, remember that Delaware’s summers get hot fast, and cars parked outside an apartment complex heat up within minutes. If you’re a dog owner running errands near your building, it’s worth understanding the real risks around leaving pets in hot cars in Delaware before you assume a quick stop is harmless.

Dogs remain the most common apartment pet across Delaware, and knowing basic facts about your own animal, like how many teeth a dog has, can help you spot dental problems that might otherwise turn into an expensive vet bill during your lease term. Responsible pet ownership, paired with a clear understanding of your lease, is usually the best defense against a denied application or a lost deposit.

Delaware’s approach to pets in rental housing puts more responsibility on tenants to read the fine print than states with stricter tenant-protection statutes. Knowing the caps on deposits, the real scope of your Fair Housing rights, and the notice periods required before a policy change gives you a much stronger position, whether you’re applying for a new unit or defending the one you already have.
