ADA & Reasonable Accommodation Rules in Delaware 2026
Service animals, emotional-support animals, and reasonable accommodation duties under the federal Fair Housing Act and 6 Del. C. § 4600 et seq..
Every Delaware landlord operates under two overlapping disability laws: the federal Fair Housing Act (42 U.S.C. § 3604(f)) and the Delaware Fair Housing Act at 6 Del. C. Chapter 46. Delaware's disability provision, 6 Del. C. § 4603A, tracks the federal standard closely rather than adding a stronger substantive rule, so the practical duties are the same statewide: you must allow reasonable modifications to the physical unit and make reasonable accommodations to your rules and policies when a resident with a disability needs them to fully use and enjoy the home.
The distinction that decides cost is simple. A modification is a physical change (a grab bar, a ramp, a widened doorway). An accommodation is a change to a policy, practice, or service (a reserved parking space, permission for an assistance animal despite a no-pet rule, a rent-due-date shift tied to benefit timing). Getting the two categories right is what keeps a routine request from turning into a Division of Human and Civil Rights complaint.
What Delaware Law Adds
Adds source of income, sexual orientation, gender identity, marital status, creed, and age.
Who pays: modifications vs. accommodations
Under 6 Del. C. § 4603A, a landlord may not refuse to permit, at the expense of the person with a disability, reasonable modifications to existing premises when those changes are necessary for full enjoyment of the home. In an ordinary private rental, the tenant pays for the physical work and you cannot block a reasonable modification just because you dislike the change.
Reasonable accommodations to rules and policies are different. Because these change a practice rather than the structure, they usually cost nothing, and the landlord absorbs that administrative cost, you cannot charge a fee or extra deposit for granting one. The main exception to the tenant-pays rule for physical work is federally assisted or subsidized housing: under Section 504 of the Rehabilitation Act, the housing provider generally bears the cost of a modification unless it is an undue financial and administrative burden.
Restoration and the escrow question
Section 4603A lets you, where it is reasonable to do so, condition permission for a rental modification on the tenant agreeing to restore the interior to its prior condition when they leave, reasonable wear and tear excepted. This applies only to interior changes that a future resident would not use, repainting a wall color is not restorable, but widened doorways and lowered counters generally stay. You cannot require restoration of changes that do not affect the next tenant's use of the unit.
You may ask for a reasonable description of the work and proof it will be done in a workmanlike manner with required permits. Where restoration is reasonable, you may negotiate a restoration escrow, but only in an amount reasonable to cover the actual restoration, not as a blanket surcharge for allowing the modification.
The interactive process
Neither the FHA nor Delaware law requires magic words. When a resident asks for a change connected to a disability, you must engage in a good-faith interactive dialogue rather than ignore or flatly reject the request. If the disability and the need are obvious, you may not demand medical proof. If neither is obvious, you may request reliable disability-related documentation confirming the disability and the connection between the disability and the requested change, but not the underlying diagnosis or full medical records.
Treat assistance animals, service animals and emotional support animals, as an accommodation, not a pet. A no-pet policy, pet rent, and pet deposits do not apply, and breed or weight limits give way to the accommodation unless the specific animal is a documented direct threat. Respond to requests promptly; an unreasonable delay can itself be treated as a denial.
When you can lawfully say no
The duty is to grant reasonable requests, not every request. You may deny when the request imposes an undue financial and administrative burden, would fundamentally alter the nature of your operations, is not tied to a disability-related need, or would pose a direct threat to the health or safety of others that cannot be reduced by another accommodation. A direct threat must rest on current, objective evidence about the individual, not stereotype or speculation.
Before you deny outright, the safer course is to propose an alternative accommodation that meets the disability-related need at lower cost or burden. Document the request, your reasoning, and any alternatives offered. A denial without that interactive record is the fact pattern that most often produces a finding against the landlord.
New construction and Delaware enforcement
Beyond individual requests, 6 Del. C. § 4603A carries the same accessible design-and-construction mandate as the federal FHA for covered multifamily dwellings, buildings with 4 or more units (all ground-floor units, or all units where the building has an elevator) built for first occupancy after September 1, 1992. Substantial alterations costing 50% or more of replacement cost can trigger accessibility upgrade duties. These are baseline build requirements, separate from any tenant request.
Complaints go to the Delaware Division of Human and Civil Rights (the former Division of Human Relations) under 6 Del. C. §§ 4610 and 4612, or to HUD. A housing complaint must be filed within one year of the discriminatory act (or its discovery); the federal HUD deadline is also one year. The Division aims to complete its investigation within 100 days of filing unless that is impracticable.
No Misrepresentation Statute in Delaware
Delaware has not enacted a statute criminalizing misrepresentation of a pet as a service or assistance animal. A Delaware landlord who suspects fraud should still process the request properly, denial without engaging in the interactive process and without requesting reliable documentation creates FHA liability that far exceeds any plausible harm from a fraudulent ESA claim.
The Cost of Mishandling a Reasonable-Accommodation Request
The most common mistake in Delaware reasonable-accommodation 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 than HUD permits, or imposes a pet fee on an assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied.
Reasonable Modification, Often Confused With Accommodation
Reasonable modification (42 U.S.C. § 3604(f)(3)(A)) is a structural change, a grab bar, a ramp, lowered cabinets. The tenant pays. The landlord must permit the modification and may require restoration to original condition at move-out (except for changes that would not significantly affect re-rental). Reasonable accommodation is a change to a rule or policy. The landlord pays no out-of-pocket cost; the cost is administrative. Delaware follows the federal rule.

Frequently Asked Questions
Does Delaware require more than the federal Fair Housing Act on accommodations?
No. Delaware's disability provision, 6 Del. C. § 4603A, closely tracks the federal Fair Housing Act rather than adding a stronger substantive duty. The practical rules, allow reasonable modifications at the tenant's expense, make reasonable policy accommodations, engage in the interactive process, are the same. Delaware's added value is a state enforcement path through the Division of Human and Civil Rights alongside HUD.
Who pays for a grab bar or ramp in a Delaware rental?
In a private, unsubsidized rental the tenant pays. Under 6 Del. C. § 4603A you must permit reasonable physical modifications, but they are made at the expense of the person with a disability. In federally assisted or subsidized housing, Section 504 shifts the cost to the housing provider unless it is an undue financial and administrative burden.
Can I make the tenant restore a modification when they move out?
Sometimes. Section 4603A lets you, where reasonable, condition permission on the tenant restoring the interior to its prior condition, reasonable wear and tear excepted. This applies only to interior changes a future resident would not use. You cannot require restoration of features like widened doorways that the next tenant can use.
What documentation can I ask for?
If the disability and the need are obvious, none. If they are not obvious, you may request reliable disability-related documentation confirming the disability and its connection to the requested change, for example, a letter from a treating provider. You may not demand the diagnosis, full medical records, or details beyond what verifies the need.
Do I have to waive my no-pet policy for an emotional support animal?
Yes, as a reasonable accommodation. Assistance animals, including emotional support animals, are treated as an accommodation, not a pet, so no-pet rules, pet rent, and pet deposits do not apply, and breed or weight limits give way unless the specific animal is a documented direct threat to others.
When can a Delaware landlord legally deny a request?
When the request imposes an undue financial and administrative burden, would fundamentally alter your operations, is not tied to a disability-related need, or poses a direct threat to others' health or safety based on current objective evidence. Even then, offer an alternative accommodation where one exists and document your reasoning before denying.
How long does a tenant have to file a discrimination complaint?
One year. A Delaware fair housing complaint must be filed with the Division of Human and Civil Rights within one year of the discriminatory act or its discovery, under 6 Del. C. §§ 4610 and 4612. The federal HUD deadline is also one year. The Division targets completing its investigation within 100 days of filing.
