ESA Weight Limits in New Hampshire: Why Size Caps Don't Apply Under the FHA

A great many renters across New Hampshire discover the same frustrating clause buried in their lease: a 25-, 40-, or 50-pound weight limit on pets. For someone whose emotional support animal happens to be a Labrador, a German Shepherd, or a Great Dane, that clause can feel like an immovable wall. It is not. Under the Fair Housing Act (FHA), an emotional support animal is not a pet in the legal sense, and a property's weight cap, size restriction, or breed list generally cannot be applied to a properly documented ESA. This guide walks through, step by step, why that is true, what New Hampshire renters need to assert the protection, and how to request the accommodation the right way.

Why Weight Limits Don't Apply to ESAs Under Federal Law

The U.S. Department of Housing and Urban Development addressed this directly in its January 2020 guidance, FHEO-2020-01, "Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act." That notice instructs housing providers to evaluate an assistance animal request individually, based on the animal's documented relationship to the tenant's disability-related need, not on a blanket policy about size, weight, or breed. A housing provider may only deny an accommodation if the specific animal poses a direct threat that cannot be reduced through other reasonable means, or if it would impose an undue financial or administrative burden on the property. "This breed is usually aggressive" or "our policy caps pets at 30 pounds" does not meet that legal standard.

New Hampshire compounds this federal protection with its own state law. RSA 354-A, New Hampshire's Law Against Discrimination, prohibits housing discrimination on the basis of disability and requires reasonable accommodations, mirroring the FHA framework. Together, the two laws mean a landlord in Manchester, Nashua, or Concord who tries to enforce a strict weight limit against a documented ESA is very likely running afoul of both federal and state housing law.

What You'll Need

Before requesting an accommodation for a large-breed or heavier animal, gather the following:

• A current ESA letter from a licensed mental health professional (LMHP) who is licensed in New Hampshire, such as an LCSW, LMFT, psychologist, psychiatrist, or licensed primary-care provider where state law permits. The letter should confirm that a licensed clinician has determined an ESA is appropriate for your therapeutic needs, without disclosing your specific diagnosis.
• A written accommodation request submitted to your landlord or property manager, ideally by email or certified mail so you retain a timestamped record.
• Your lease agreement, so you can identify and reference the exact pet policy language you are asking the landlord to waive.
• Basic information about the animal (species and, if requested, general size), though you are never obligated to disclose the animal's breed, weight, or medical records as a condition of accommodation.
• Patience and a paper trail. HUD guidance does not set a strict response deadline for landlords, but a reasonable timeframe is generally expected, and documenting every exchange protects you if a dispute arises later.

Step-by-Step: Requesting Your Accommodation

Step 1: Confirm Your Letter Meets New Hampshire and HUD Standards

Review your ESA letter to ensure it is signed and dated by an LMHP licensed in New Hampshire, printed on letterhead, and states that the clinician has an established relationship with you sufficient to make this determination. A letter that is vague, undated, or issued by someone without an active New Hampshire license is far easier for a landlord to challenge, so accuracy here matters more than speed.

Step 2: Submit a Written Accommodation Request

Send your landlord a written request that names your ESA, cites the FHA and RSA 354-A, and attaches your letter. State plainly that you are requesting a reasonable accommodation to the property's pet or weight policy for an assistance animal, not a pet.

Step 3: Reference HUD Guidance if the Landlord Pushes Back

If the property manager cites a weight limit or a "no large dogs" clause, you can point them directly to FHEO-2020-01, which states that a housing provider "may not deny a requested accommodation" on the basis of blanket breed, size, or weight restrictions and must instead conduct an individualized assessment of the specific animal.

Step 4: Keep the Exchange in Writing

Continue all communication in writing. If a landlord raises new objections verbally, follow up with a short email summarizing what was said. This creates a record that many people find useful if the dispute needs to go further.

Step 5: Escalate if Necessary

If a landlord unreasonably denies or ignores your request, New Hampshire renters may file a complaint with HUD's Office of Fair Housing and Equal Opportunity or with the New Hampshire Commission for Human Rights. For guidance specific to your situation, consult a New Hampshire-licensed attorney or your local legal aid office, since fair housing enforcement and remedies are legal matters outside the scope of this article.

Tips for a Smoother Process

• Lead with your letter, not an argument. Most disputes soften once a landlord sees documentation from a licensed clinician.
• Don't volunteer more than is required. HUD guidance limits what a landlord may ask; you are not required to share your diagnosis, medical records, or the animal's training history.
• Address related lease clauses at the same time. If your lease also lists breed restrictions, it's worth reviewing how breed restrictions apply to ESA dogs in New Hampshire, since the same individualized-assessment standard applies there.
• Renting somewhere with a strict no-pets policy? The accommodation obligation still applies. See how no-pets policies interact with ESA accommodation requests in New Hampshire.

Common Mistakes to Avoid

1. Assuming a verbal "yes" is enough. Always get the accommodation confirmed in writing, even if a property manager verbally agrees.
2. Using an out-of-state or expired letter. A landlord can reasonably question documentation that doesn't reflect a current relationship with a New Hampshire-licensed clinician.
3. Framing the request around a pet fee. Assistance animals are not pets, so offering to simply "pay the pet fee" can muddy your legal position. The correct path is a reasonable accommodation request, not a negotiated pet policy exception.
4. Escalating before documenting. Filing a complaint without a written record of your request and the landlord's response makes the process harder than it needs to be.
5. Believing weight limits are always unenforceable. In rare cases involving a genuine, individualized safety concern about a specific animal (not its breed or size in the abstract), a landlord may have grounds to raise concerns. This is why individualized assessment, not automatic override, is the legal standard.

What You Can Reasonably Expect

Many renters with a properly documented ESA letter and a clear, written request find that New Hampshire landlords ultimately do waive weight and size restrictions, since the FHA and RSA 354-A leave little room for a categorical denial. That said, outcomes vary by property, by landlord, and by the specific facts involved, and a licensed mental health professional's individualized determination, not a general weight-limit rule, is what ultimately governs whether an ESA accommodation is appropriate for your situation.
