# ESA Letter in Wilmington, DE: A Right With No Word for It

> An ESA letter in Wilmington rests on a chapter that never says animal: 6 Del. C. § 4603A(a)(2), the duty Delaware told everyone to construe liberally.

## Key facts

- Population: 73,176
- Households renting: 52%
- Typical pet deposit (as a pet): Barred as accommodation
- Typical pet rent (as a pet): $25-$50/mo for pets
- Breed/weight limits common: yes
- Pet fees, deposits, and breed limits with a valid ESA letter: none (FHA reasonable accommodation)

## More renting households than anywhere in Delaware, at a rent below the state's

Wilmington holds **16,450 renting households** out of 31,655 occupied homes,
on the 2020–2024 American Community Survey five-year estimate. That is 52.0
percent of the city, and 15.1 percent of every renting household in
Delaware, the largest single concentration of renters in the state by a wide
margin.

It is not the largest *share*. Laurel, a Sussex County town of 4,395, rents
at 60.4 percent, and Dover at 53.1 percent also sits above the city.
Wilmington leads on the count, not the proportion, and the difference
matters when someone tells you the state's rental law is written for its
biggest city.

Median gross rent here is **$1,224**. The Delaware figure is **$1,401**.
Wilmington rents a hundred and seventy-seven dollars *under* the state
median, because that $1,401 is set by New Castle County's suburbs and the
Sussex beach resorts rather than by the city they surround. The 2024 Census
estimate puts Wilmington at 73,176 residents.

So there are more tenants here than anywhere in Delaware who will one day
ask a landlord to make an exception for an animal. And when they go looking
for the Delaware statute that covers it, they find a Fair Housing Act with
no animals in it.

## The chapter that never says the word

The Delaware Fair Housing Act is 6 Del. C. ch. 46. The whole chapter, 119 kilobytes of statutory
text, was read for this page and searched. **"Animal" does not appear in it. Neither does "pet,"
"service animal," "assistance animal" or "support animal."** Not once, in any of its twenty-one
sections.

Read that as an omission and you would conclude Delaware has nothing to say. Read it as drafting
and it is the reason the right works at all.

## What the legislature wrote instead

**6 Del. C. § 4603A(a)** sets out what disability discrimination includes:

> "(2) A refusal to make **reasonable accommodations in rules, policies, practices or services**,
> when such accommodations **may be necessary to afford such person equal opportunity to use and
> enjoy a dwelling**"

There is no species in that sentence. No training standard, no breed, no weight, no certificate,
no list of qualifying animals. It is a duty about **rules** — and a no-pets clause is a rule. The
accommodation is the exception carved into it.

Then the instruction the General Assembly attached to the whole chapter, **§ 4601(b)**:

> "This chapter shall be **liberally construed** to the end that its purposes may be accomplished
> and all persons may fully enjoy equal rights and access to housing for themselves and their
> families. Furthermore, in defining the scope or extent of any duty imposed by this chapter,
> **including the duty of reasonable accommodation**, higher or more comprehensive obligations
> established by otherwise applicable federal, state, or local enactments may be considered."

Two useful things in one sentence. Delaware told readers of this chapter to construe it broadly,
and it named the duty of reasonable accommodation while doing so — in a chapter whose operative
provisions never name an animal. That is a better starting posture than most states hand a tenant.

The charge that usually comes attached is **§ 4603(b)(2)**, which makes it unlawful "to
discriminate against any person in the **terms, conditions, or privileges** of sale or rental of a
dwelling" because of disability. Behind both sits the federal Fair Housing Act at 42 U.S.C.
§ 3604(f)(3)(B), with 24 C.F.R. § 100.204 saying the same thing in regulation.

## What a Wilmington landlord still gets to argue

Delaware states the limit twice, which is unusual, and an honest page carries it.

**§ 4603(c)**: nothing requires a dwelling be made available to a person with a disability "whose
tenancy would constitute a **direct threat to the health or safety of other individuals** or whose
tenancy would result in **substantial physical damage to the property of others.**" **§ 4603A(f)**
repeats it almost word for word.

Note what kind of test that is. It asks about a tenancy and an animal in front of you — not about
a breed, a weight class or an insurance schedule. A landlord who reaches for it has to say what
this animal has done or will do.

There is one more provision worth knowing and worth reading carefully. **§ 4603A(a)(4)** makes it
discrimination "to make an inquiry to determine whether **an applicant for a dwelling** … has a
disability or to make inquiry as to the nature or severity of a disability of such a person," with
exceptions for inquiries "made of all applicants." That is a screening rule, aimed at what is
asked of people applying for housing. Nothing in the chapter addresses what a housing provider may
ask *after* a tenant has made a request of their own, which is a different posture entirely. No
Delaware decision construing the subsection was found, so this page states what it says and stops.

## Where a Wilmington complaint goes

The **Division of Human and Civil Rights** enforces the state Fair Housing Law, and its New Castle
County office is in the city, at 820 N. French Street. Its own FAQ answers the first question most
people have: "**No, there is no fee to file a complaint.**"

Two clocks, and they belong to different forums. A complaint to the Division must come "not later
than 1 year after an alleged discriminatory housing practice has occurred or terminated, **or not
later than 1 year after such practice has been discovered or reasonably should have been
discovered**", 6 Del. C. § 4610(a)(1)a.1. A private civil action under § 4613 runs **two** years
on the same discovery alternative, and the two-year period does not count time while an
administrative proceeding is pending. Missing the first deadline is not the same as losing the
claim, and the two numbers are not interchangeable.

## What has to be shown when the statute names nothing

Because § 4603A(a)(2) names no animal and no document, the whole question
moves onto the showing. The Division publishes what that showing looks like,
in its own words:

> "Fair housing laws only require housing providers to make accommodations when there is a
> connection, or '**nexus**,' between the requested accommodation and the person's disability"

and on documentation:

> "**From a health professional or other person who can establish that the person has a disability
> and explain the nexus between the disability and the accommodation request**, unless the
> disability is apparent to the housing provider."

The Division says nothing at all about assistance animals (its guidance was
read in full and the word never appears), so it is quoted here for what it
does say, which is about disability, nexus and the interactive process a
provider is expected to engage in.

That is the target. Two findings: a disability, and a connection between it
and this animal. A certificate cannot make either. Neither can a registry,
and Delaware has none to offer, since the one place the Code says
"certified" never says by whom.

Start with someone already treating you. A clinician who has seen you over
time makes the better document and charges you nothing extra for it. The
friction is real: many practices write no disability findings at all as a
matter of policy, and a provider who has met you twice may properly decline
to make one. Wilmington is the easiest place in Delaware to find specialist
capacity (most of the state's is in New Castle County), and it is still
weeks of waiting for a first appointment.

Where that route is closed, a licensed evaluation is the same examination
arranged deliberately: someone licensed in Delaware works out whether a
disability exists and whether this animal answers it, then writes the
finding or says plainly that they will not. Both endings are real, and a
service whose answer is decided before you arrive is selling paper.

Delaware wrote a housing right without ever using the word for the thing you
want to keep. What it used instead was a duty and a showing, and the showing
is a finding somebody has to make.

## What Wilmington landlords can and cannot do

**Cannot:**
- May not refuse a reasonable accommodation in rules, policies, practices or services where it may be necessary to afford a person with a disability equal opportunity to use and enjoy a dwelling: 6 Del. C. § 4603A(a)(2).
- May not discriminate because of disability in the terms, conditions or privileges of the rental, or in the services and facilities provided with it: 6 Del. C. § 4603(b)(2). This is where a charge attached to a required animal is met.
- May not require a security deposit above one month's rent where the agreement runs a year or more, or on a month-to-month tenancy once it has lasted a year, 25 Del. C. § 5514(a)(2)–(3), and those limits do not apply to furnished units at all, § 5514(a)(4).
- May not inquire whether an applicant for a dwelling has a disability, or as to its nature or severity, except by inquiries made of all applicants alike: 6 Del. C. § 4603A(a)(4).

**Can:**
- May require a pet deposit, capped at one month's rent regardless of the length of the agreement, 25 Del. C. § 5514(i)(2), but that deposit is a separate and additive ceiling from the security deposit, which § 5141(33) defines as "exclusive of a pet deposit."
- Must remit the deposit and provide an itemized list of damages within twenty days of the end of the tenancy; failure to itemize is an acknowledgment that no payment for damages is due, and failure to remit entitles the tenant to double the amount wrongfully withheld, 25 Del. C. § 5514(e)–(g).
- May charge an application fee of no more than the greater of 10 percent of the monthly rent or $50, on pain of double damages, 25 Del. C. § 5514(d).
- May decline where the tenancy would constitute a direct threat to the health or safety of others, or would result in substantial physical damage to the property of others, 6 Del. C. §§ 4603(c) and 4603A(f). The assessment is individualised.
- Is outside the state accommodation duty only in the case 6 Del. C. § 4607(e) describes: a dwelling of no more than four families where the owner occupies one of them. Discriminatory advertising under § 4603(b)(3) remains unlawful even there, and the federal Fair Housing Act runs its own exemptions on its own terms.

## How to get an ESA letter in Wilmington

1. **Check that you qualify**, Answer a short screening about how your condition affects daily life in Wilmington. No diagnosis paperwork needed up front. (About 5 minutes: free)
2. **Connect with a licensed professional**, You are matched with a provider licensed for Delaware clients who reviews your situation in a telehealth evaluation. (Telehealth evaluation)
3. **Complete your evaluation**, The professional evaluates whether an emotional support animal alleviates symptoms of a condition recognized in the DSM-5. Honest evaluations, not everyone qualifies. (Most of Our Applicants Qualify)
4. **Receive your signed letter**, Your letter arrives on the professional's letterhead with their license number: the documentation Delaware landlords may lawfully request. (Typically within days of approval)
5. **Send it to your landlord**, Submit the letter with a short reasonable-accommodation request. Pet fees, pet deposits, and breed limits no longer apply to your animal in Wilmington. (Protection under FHA + state law)

## Conditions that can qualify for an ESA

No fixed government list exists. A licensed professional evaluates whether an animal alleviates symptoms of a DSM-5-recognized condition, commonly:

- Generalized anxiety disorder
- Major depressive disorder
- Post-traumatic stress disorder (PTSD)
- Panic disorder
- Social anxiety disorder
- Obsessive-compulsive disorder (OCD)

## Frequently asked questions

### The Delaware Fair Housing Act never mentions animals. Does that mean it does not cover mine?

The opposite. The whole of 6 Del. C. ch. 46 was read for this page and the words animal, pet, service animal, assistance animal and support animal appear nowhere in it. Because § 4603A(a)(2) is phrased around rules, policies, practices and services rather than around species or training, there is no animal test in it for a landlord to argue you fail.

### What does the "liberally construed" instruction in § 4601(b) actually do for a request?

It sets the reading posture for the whole chapter, and it names the duty while doing so: the chapter is to be liberally construed, and in defining the scope of any duty it imposes, "including the duty of reasonable accommodation," higher or more comprehensive obligations from federal, state or local enactments may be considered. Most states give a tenant no such sentence to start from.

### Wilmington has more renters than anywhere in Delaware. Does that change the law here?

No, and the claim needs care. Wilmington holds 16,450 renting households, 15.1 percent of the state's 108,655, which is the largest count anywhere in Delaware. It is not the highest renter share: Laurel is, at 60.4 percent, with Dover at 53.1 percent above the city's 52.0 percent. Neither figure changes what 6 Del. C. § 4603A(a)(2) requires.

### Can a Wilmington landlord refuse because of the animal's breed or size?

Delaware gives the landlord an individualised test, not a category one. § 4603(c) and § 4603A(f) both allow refusal where the tenancy would be a direct threat to the health or safety of others or would cause substantial physical damage to the property of others. Those ask what this animal has done or will do; a blanket breed or weight rule is not that assessment.

### May a landlord ask about my disability when I apply for an apartment?

§ 4603A(a)(4) makes it discrimination to ask an applicant for a dwelling whether they have a disability, or about its nature or severity, except for inquiries made of all applicants, such as ability to meet the requirements of tenancy. That subsection is about screening applicants. Nothing retrieved from the chapter addresses what may be asked in response to a request a tenant has already made, and no Delaware decision construing it was found.

### Where does a Wilmington fair housing complaint go, and what does it cost?

To the Division of Human and Civil Rights, which has its New Castle County office at 820 N. French Street in Wilmington. The Division's own FAQ says there is no fee to file. A complaint must reach it within one year of the practice, or within one year of when it was discovered or reasonably should have been discovered, under 6 Del. C. § 4610(a)(1)a.1.

### Is the one-year deadline the only clock I need to watch?

No, and confusing the two is a common error. One year is the administrative window at the Division. A private civil action under 6 Del. C. § 4613 may be brought within two years of the practice or of its discovery, whichever occurs last, and that two-year period does not count time while an administrative proceeding is pending. Missing the first deadline does not automatically end the claim.
