Pet-Friendly Housing Laws in Delaware: What Renters and Landlords Should Know
August 23, 2026
Delaware’s Landlord-Tenant Code barely mentions the word “pet,” yet that silence shapes nearly every rental decision involving animals in the state. Pet-friendly housing laws in Delaware combine a landlord-friendly state code with federal Fair Housing protections, creating a system where private owners have wide discretion but disability-related exceptions carry real legal weight. Whether you’re a tenant trying to understand what a landlord can legally charge or a property owner drafting a pet policy, knowing where state law ends and federal protection begins can save you from an expensive dispute.
This breakdown covers what Delaware statutes actually say about pet deposits, breed restrictions, service animals, and emotional support animals, along with the local ordinances that add another layer in cities like Wilmington and Newark.
Pro Tip: Always request your pet policy in writing before signing a lease. Delaware law expects rental terms, including pet rules, to be spelled out clearly in the rental agreement rather than assumed.
Can Landlords Refuse to Rent to Pet Owners in Delaware
Delaware gives landlords broad authority over whether to accept pets at all. The Delaware Landlord-Tenant Code does not provide specific regulations for allowing or prohibiting pets, instead focusing on the maintenance and operation of the property. That means a “no pets” policy is generally enforceable unless the animal in question is a service animal or emotional support animal protected under disability law.
Property analysts who work with Delaware landlords confirm this hands-off approach. No state law mandates that you accept pets, except for assistance animals; you decide if pets are allowed, you set the rules on breed restrictions, size limits, and number of pets, and you determine the fees. The one catch is documentation: whatever rules a landlord establishes must be clearly spelled out in the lease agreement.
Where landlords lose flexibility is around protected classes. The Fair Housing Act influences rental property rules concerning pets, particularly with respect to protected classes, ensuring that landlords do not discriminate against tenants based on race, gender identity, sexual orientation, or other protected categories when applying pet policies unevenly. A landlord can legally reject an applicant for owning a large dog, but can’t use pet ownership as a pretext to discriminate based on a tenant’s disability status. For details on how support animals fit into this picture, Delaware’s emotional support animal housing rules outline the exception in full.
Pet Deposit, Pet Rent, and Pet Fee Rules in Delaware
Delaware law directly addresses pet deposits, even though it stays quiet on whether pets must be allowed at all. Under the state code, a landlord may require a pet deposit, but no landlord may require a pet deposit in excess of one month’s rent, regardless of the duration of the rental agreement. That cap applies statewide and doesn’t scale up for larger pets or multiple animals.
How that deposit gets used follows a specific order. Damage to the rental unit caused by an animal is first deducted from the pet deposit, and where the pet deposit is insufficient, the remaining damages may be deducted from the security deposit. Ordinary wear doesn’t count against either deposit: Delaware defines normal wear and tear as natural deterioration from ordinary use, such as minor scratches on floors, slight carpet wear, or small nail holes, and landlords can’t deduct from deposits for normal wear.
Tenants sometimes confuse pet deposits with pet fees, but Delaware treats them differently. Pet deposits are separate from the security deposit and cannot exceed the amount of monthly rent, but in lieu of a pet deposit, a landlord may charge a monthly fee for owning a pet, and property owners are not allowed to charge both a pet deposit and a pet fee. The table below breaks down how each charge typically functions.
| Charge Type | Refundable? | Legal Limit in Delaware | Can Be Combined With Others? |
|---|---|---|---|
| Pet Deposit | Yes, minus pet-related damage | Capped at one month’s rent | No, not with a pet fee |
| Pet Rent | No, ongoing monthly charge | No statutory cap | Typically yes, separate from deposits |
| Pet Fee | Generally non-refundable | No statutory cap, but nonrefundable fees face scrutiny | No, not with a pet deposit |
Application fees are also capped separately from pet charges. Application fees can be no more than 10% of the monthly rent or $50, and that fee can be used by the landlord to check the tenant’s credit and background, but landlords cannot charge separate credit check fees. If a landlord overcharges here, the tenant is entitled to damages equal to double the amount unlawfully charged as an application fee.
Security deposits, including pet deposits, must sit in a protected account. A separate security deposit bank account is required, and it must be with a federally insured bank, with the landlord disclosing the account’s location to the tenant. When a lease ends, the landlord must timely return any security deposit, pet deposit, and prepaid rent, except amounts the landlord is entitled to retain under the code. Tenants who also keep livestock or backyard animals covered by Delaware’s pet vaccination requirements should keep those records on hand, since landlords sometimes request proof of current vaccinations alongside deposit paperwork.
Breed and Size Restrictions in Delaware
Private landlords retain the right to restrict breeds in Delaware, even as the state limits what cities and counties can do. Delaware law allows breed restrictions, though breed restrictions may limit a landlord’s tenant pool, they cannot be applied to service animals, and some insurance companies require them as a valid consideration. A lease that excludes specific breeds, such as pit bull-type dogs or Rottweilers, is generally enforceable as long as it applies to pets rather than legally protected assistance animals.
The state’s approach to breed regulation shifted dramatically with House Bill 13. The legislation specifies that municipal governments shall enact no law, ordinance, or regulation relating to dogs, or restrictions on dogs, based on a dog’s breed or perceived breed. As a result, Delaware’s statewide law preempts breed-specific ordinances, meaning no municipality in the state can currently enforce a pit bull ban. Wilmington’s own history illustrates the shift: the city council voted 11-0 to remove breed-specific language from city laws and eliminate a separate registration process for pit bulls, though the dogs remain subject to standard licensing.
Important Note: HB 13 restricts what cities can do about dog ownership and animal control, but it does not override a private landlord’s ability to set breed policies inside a lease. A tenant can legally own a restricted breed in Wilmington while still being turned down by an individual landlord whose lease excludes that breed.
Owners of specific breeds often want details beyond the general rule. For a closer look at how these restrictions play out for one commonly targeted breed, Delaware’s pit bull laws cover the history and current statewide standard, while similar considerations apply to Rottweiler ownership rules in Delaware for tenants navigating landlord-imposed limits.
Service Animal Rights in Delaware
Service animals occupy a distinct legal category separate from pets, and Delaware’s code reflects that. State law defines the term precisely: a “service dog” means any guide dog, signal dog, or other animal individually trained to do work or perform tasks for the benefit of an individual with a disability, including guiding individuals with impaired vision, alerting individuals with impaired hearing to intruders or sounds, providing minimal protection or rescue work, pulling a wheelchair, or fetching dropped items.
Because service animals aren’t legally treated as pets, the deposit rules change entirely. If a tenant keeps a pet that is not a service animal, the landlord can ask for an additional pet deposit capped at one month’s rent, deductible only for pet-related damages — but that deposit requirement drops away for a genuine service animal. The same logic applies to breed policy: landlords cannot apply breed restrictions to service animals, regardless of what the lease says about pets generally.
Tenants relying on a service animal should keep documentation of the animal’s training and task-based function on hand, since landlords are entitled to ask limited questions about the disability-related need when it isn’t obvious. Delaware also criminalizes interference with a working service dog, giving these animals legal protections that go beyond housing law alone.
Emotional Support Animal Rights in Delaware
Emotional support animals fall under a different framework than service animals, but they carry strong housing protections through federal law. Under the Fair Housing Act, Delaware landlords must accommodate emotional support animals, even in no-pet housing, without charging extra fees or deposits. This applies even to buildings with strict no-pet policies, since ESAs are treated as a disability accommodation rather than a pet.
That protection isn’t unconditional. Landlords may deny an ESA if it poses a direct threat, causes significant property damage, or creates an undue financial burden, but cannot refuse based on bias or a no-pet policy. Documentation matters here: tenants should have a valid ESA letter from a licensed mental health professional to secure their housing rights and avoid disputes with landlords.
Delaware has also added teeth to the documentation requirement to curb abuse of the system. Under Delaware law (SB 219), intentionally providing fraudulent ESA documentation can result in civil penalties of up to $500 for a first offense. Unlike service animals, ESAs are not required to undergo specific training, which is precisely why a legitimate letter from a licensed provider carries so much weight in a dispute.
HOA communities follow the same federal standard as private landlords. In Delaware, the law states that emotional support animals are allowed under the Federal Fair Housing Act, and housing facilities cannot deny housing to someone or their service or support animal due to their disability or need. For a full walkthrough of documentation, timelines, and denial appeals, Delaware’s ESA housing law guide goes deeper into the accommodation request process. Renters comparing rules across state lines may also find it useful to review Pennsylvania’s ESA housing laws or Virginia’s ESA housing laws, since both neighboring states apply the same federal framework with slightly different state-level wrinkles.
Local City and County Pet Housing Ordinances in Delaware
State law sets the floor, but Delaware’s cities and counties still shape day-to-day pet ownership through licensing and animal control rules. Every dog owner in the state needs a license, and anyone who maintains a kennel where more than four dogs are kept for show, trial, sale, breeding, or other purposes may apply for a kennel license in lieu of an individual dog owner license, valid for one year from the date of purchase.
Wilmington’s animal control ordinance shows how local rules can extend beyond what state law requires. Restrictions that had previously only applied to pit bulls, like a mandate that they be walked on leashes no longer than six feet, have since been expanded to include all dogs. That change means every dog owner in the city, regardless of breed, now follows the same leash standard. Tenants should check current requirements through Delaware’s leash laws before assuming a suburban county rule applies inside city limits — actual local ordinances can vary by municipality.
College towns add their own dynamics to the rental market. As a college town, Newark has a busy rental market where understanding ESA rights is crucial, and student housing, apartments, and rental properties in the city must comply with federal fair housing laws the same as any other landlord in the state.
Renters keeping animals beyond cats and dogs run into a separate layer of local rules entirely. Many Delaware municipalities and HOAs regulate backyard livestock and unusual pets through zoning rather than the landlord-tenant code, so anyone considering backyard chickens or goat ownership at a rental property should confirm both the lease terms and the local zoning ordinance before bringing the animal home.
What to Do If a Landlord Violates Pet Housing Laws in Delaware
Tenants who believe a landlord has overstepped Delaware’s pet housing rules have several concrete options, starting with documentation. Delaware law requires landlords to operate transparently from the start of the lease: landlords must provide new tenants with a summary of the Landlord-Tenant Code at the beginning of the rental term, and a written pet policy should follow that same standard of clarity.
- Document everything in writing. Save texts, emails, and lease addendums related to the pet dispute, including any ESA or service animal accommodation requests.
- Check the deposit math. If a landlord has charged more than one month’s rent as a pet deposit, or charged both a pet deposit and a pet fee, that likely violates state limits.
- Request the denial in writing. If a reasonable accommodation request for an ESA or service animal was denied, ask the landlord to state the specific reason, since a vague “no pets” policy isn’t a valid defense against a disability accommodation claim.
- File a HUD complaint for Fair Housing violations. Disability-based denials, illegal fees charged against ESAs, or refusal to engage in the accommodation process can be reported to the U.S. Department of Housing and Urban Development.
- Pursue damages for fee violations. If the landlord demands more than the allowed amount, the tenant may sue the landlord for up to twice the amount of application fees charged unlawfully.
- Contact Delaware’s Justice of the Peace Court. Most landlord-tenant disputes involving deposits and fees fall within small claims jurisdiction, making this the most direct venue for recovering money owed.
Important Note: This article is for general informational purposes and does not constitute legal advice. Pet-related lease disputes can involve overlapping state and federal law, so tenants and landlords facing an active dispute should consult a Delaware landlord-tenant attorney or a local legal aid organization for guidance specific to their situation.
Most pet housing disputes in Delaware come down to two things: whether the animal legally counts as a pet or a protected assistance animal, and whether the fees charged match what the state code actually allows. Landlords who keep pet policies in writing and cap deposits correctly avoid the bulk of these conflicts, while tenants who keep ESA and service animal documentation current protect themselves well before a disagreement ever reaches a courtroom.
