Getting an ESA Letter in Wilmington, DE
A legitimate ESA letter is one page from a Delaware-licensed mental health professional. It is not a certificate, a registration or an ID card, and in Wilmington it is used for one thing: asking a housing provider for an exception to its pet policy.
Delaware has no statutory waiting period, so a Delaware-licensed therapist can evaluate you and, if you qualify, your letter typically arrives by email about 15 minutes after approval. You talk with a therapist, by phone or video, about how your condition affects daily life and what your animal does for you. They decide; you do not buy an outcome.
Delaware has its own fair housing law, but how its agency treats untrained emotional support animals after HUD's May 2026 change is still settling, so documentation quality matters more than it used to.

ESA Housing Law in Wilmington
Local, state and federal rules stack on top of each other here. Each can add protection; none can take away what another gives you.
Local
Our review did not confirm a Wilmington or county fair housing ordinance covering disability, so this page relies on Delaware and federal law. If one applies to your building, it can only add protection.
Delaware
6 Del. C. § 4603A — Delaware Fair Housing Act — accommodation for people with disabilities. Complaints: Delaware Division of Human Relations.
Federal
The Fair Housing Act still requires landlords to consider accommodation requests. Since May 22, 2026, HUD itself pursues complaints only for individually trained animals; your private right to sue is unchanged. What changed →

Who qualifies
Who May Qualify for an ESA Letter in Wilmington?
Therapists do not work from a list of approved diagnoses. They look at how a condition affects your daily life and whether the animal eases it. Common examples among Wilmington clients:
What the evaluation looks for
- The animal already lives with you or will once the request is approved
- No prior diagnosis required; many people are assessed for the first time
- You are 18 or older, or a parent or guardian takes part
- An animal that eases symptoms in a way you can describe
- An honest conversation with a therapist who can also say no
Your ESA Letter in Wilmington: Its Reach and Its Limits
It helps you
- Keep your diagnosis private while still showing a verified need
- Make the request before or after you move in — during an application counts
- Get a decision in writing, which you need if you have to escalate
- Ask for pet fees to be waived — no longer automatic federally after May 2026, so ask in writing
It does not
- Carry over from a therapist licensed in another state
- Excuse you from paying for damage your animal causes
- Need a registry, certificate, ID card or vest — none of those carry legal weight
- Override a lawful denial for a direct threat, substantial damage or an exempt property
How to Get Your ESA Letter in Wilmington
Three steps. You are not charged for a letter unless the therapist approves you.
Evaluation with a Delaware therapist
Your evaluation is with a therapist licensed where you live. They can approve you, and they can decline.
Your letter, ready to send
Approval means a signed letter in your inbox shortly after the appointment, on letterhead with the therapist's license details.
Why Wilmington Renters Choose Us
Private by default
Your letter confirms a need without naming a diagnosis, and your clinical information is handled under HIPAA.
Written for 2026
Our guidance reflects HUD's May 2026 change and Delaware's own rules, so you are not working from outdated advice.
No registries, ever
We do not sell certificates, vests or ID cards, because they carry no legal weight and can weaken your request.
Flat pricing
$129 for up to two animals. No subscription, no renewal auto-charge, no add-on "registration."
How to Use Your ESA Letter With a Wilmington Landlord
1Send a written request
Put it in writing. Two or three sentences are enough, plus your letter; a landlord's own "ESA form" is optional, not a requirement.
2Answer only what is fair
If the landlord asks follow-up questions, answer about the need, not the diagnosis. Your records stay private.
3Keep the paper trail
Dates, emails, the lease clause and any reply. If this turns into a complaint, the record is the case.
4If you are denied
Ask for the reason in writing, then contact Community Legal Aid Society, Inc. (CLASI) or Delaware Division of Human Relations. A HUD complaint has a one-year window.

DE letter checklist
What a Valid DE ESA Letter Must Include
These are the things a Wilmington leasing office checks first. Miss one and the request stalls.
- A Delaware-licensed therapist's signature
Out-of-state signatures are the most common reason letters fail.
- License number, type and issuing state
Managers check it against the Delaware licensing board.
- A statement of disability-related need
That you have a disability and the animal helps with it — never the diagnosis.
- A current date
Most landlords treat a letter older than 12 months as stale.
- No registry certificate attached
A purchased certificate undermines an otherwise good letter.

About the PSD letter: it is documentation from a licensed therapist, not a certificate or an ID. Under the ADA, public access comes from your dog being individually trained to do work or tasks for your disability. Businesses are allowed to ask only two questions and are not allowed to require paperwork. Nobody can sell you access rights — anyone who says otherwise is selling a novelty.
You are charged only after a therapist approves you. We may place a temporary authorization hold on your card beforehand to confirm it is valid; a hold is not a charge and is released if you are not approved.
100% refund if your landlord denies your ESA. If your housing provider refuses the accommodation after you submit a letter we issued, we refund what you paid in full. Full terms, including what a claim needs, on our refund policy page.
