Derry is New Hampshire's fifth-largest city, with about 33,990 residents in Rockingham County. Roughly 29.8% of its households rent — the lowest renter share among New Hampshire's five largest cities — which makes the pet clause in a lease a practical question for a lot of people here.

What a Derry landlord actually needs from you is short: reliable confirmation, from someone licensed in New Hampshire, that you have a disability and that your animal helps with it. That is all an ESA letter is — and a properly written one says nothing more.
New Hampshire has no statutory waiting period, so a New Hampshire-licensed therapist can evaluate you and, if you qualify, your letter typically arrives by email about 15 minutes after approval. It is a clinical conversation rather than a form, and approval is not guaranteed — which is exactly why a Derry property manager can rely on it.
New Hampshire 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.

29.8% of Derry households rent, the lowest renter share among New Hampshire's five largest cities. Median gross rent is $1,547 a month — 4th-highest median rent of New Hampshire's five largest cities, against $1,564 in Manchester.
In a market like this, management companies tend to standardize pet rules across their buildings. The rule you meet at one property is often the rule at the next, which is why knowing how to request an accommodation matters more than finding a pet-friendly unit.

Local, state and federal rules stack on top of each other here. Each can add protection; none can take away what another gives you.
Our review did not confirm a Derry or county fair housing ordinance covering disability, so this page relies on New Hampshire and federal law. If one applies to your building, it can only add protection.

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 →

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 Derry clients:
Three steps. You are not charged for a letter unless the therapist approves you.
A short questionnaire tells you whether an emotional support animal is likely to be appropriate, and shows New Hampshire's timeline before you commit.
A professional licensed in New Hampshire meets you by phone or video. It is a clinical conversation, not a form.
Approval means a signed letter in your inbox shortly after the appointment, on letterhead with the therapist's license details.
Our guidance reflects HUD's May 2026 change and New Hampshire's own rules, so you are not working from outdated advice.
Your letter confirms a need without naming a diagnosis, and your clinical information is handled under HIPAA.
$129 for up to two animals. No subscription, no renewal auto-charge, no add-on "registration."
We do not sell certificates, vests or ID cards, because they carry no legal weight and can weaken your request.
Say you have a disability, that you are asking for an accommodation to the pet policy, and attach your letter. No special form is required.
If the landlord asks follow-up questions, answer about the need, not the diagnosis. Your records stay private.
Note when you sent the request and how they responded. Silence for weeks is itself worth recording.
Ask for the reason in writing, then contact New Hampshire Legal Assistance (Fair Housing Project) or New Hampshire Commission for Human Rights. A HUD complaint has a one-year window.

These are the things a Derry leasing office checks first. Miss one and the request stalls.
Out-of-state signatures are the most common reason letters fail.
Managers check it against the New Hampshire licensing board.
That you have a disability and the animal helps with it — never the diagnosis.
Most landlords treat a letter older than 12 months as stale.
A purchased certificate undermines an otherwise good letter.
A psychiatric service dog is trained to do specific work, such as grounding you during a flashback or guiding you out of a crowd. If that describes your dog, a PSD letter records those tasks, and trained animals are what HUD still enforces for after May 2026.
Pricing
The same flat price as everywhere in New Hampshire. No subscription, and no charge for a letter unless a New Hampshire-licensed therapist approves you.
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.
Questions
Yes, for housing, when it comes from a therapist licensed in New Hampshire after a real evaluation. It supports a reasonable accommodation request to your landlord; it does not register your animal or give it public access.
New Hampshire has no statutory waiting period, so a New Hampshire-licensed therapist can evaluate you and, if you qualify, your letter typically arrives by email about 15 minutes after approval.
Since HUD's May 2026 change, a fee waiver for an untrained emotional support animal is no longer automatic federally. Ask for it in writing; whether it is required now depends on New Hampshire law and your landlord. Damage is always chargeable. How fees work now →
Use a therapist licensed in New Hampshire. Telehealth crosses state lines but licensure does not, and an out-of-state signature is the most common reason a letter gets rejected.
No. A landlord may verify that you have a disability-related need for the animal. They are not entitled to your diagnosis or your medical records, and a good letter does not include either.
They must consider the request, but may deny it for a direct threat, substantial damage, undue burden, an exempt property or documentation that is not credible. Ask for any denial in writing. New Hampshire Legal Assistance (Fair Housing Project) can help you respond. If you are denied →
Locally: New Hampshire Legal Assistance (Fair Housing Project). Statewide: New Hampshire Commission for Human Rights. Federally: a HUD complaint within one year, or a private Fair Housing Act claim within two.
No. Public access belongs to trained service animals under the ADA. A Derry business may decline an emotional support animal, and an ESA letter does not change that.
