New Hampshire Pet and ESA Laws: The Landlord and Tenant Guide

Animals in a New Hampshire rental fall into two very different legal buckets, and confusing them is where most landlord liability arises. An ordinary pet is governed by the lease and state law, so a landlord may set pet rules, impose reasonable breed or weight policies, and charge a pet deposit within New Hampshire’s security-deposit cap and pet rent. A service animal or emotional support animal is not a pet under the federal Fair Housing Act, so the pet rules, fees, breed limits, and weight limits simply do not apply to it. New Hampshire has no standalone emotional-support-animal statute; instead the federal Fair Housing Act and the New Hampshire Law Against Discrimination protect assistance animals, and the New Hampshire Commission for Human Rights enforces the state side. This guide walks the whole framework so you can stay compliant.

Below you will find how New Hampshire treats pet deposits, pet fees, and pet rent for an actual pet, how a pet deposit fits inside the state security-deposit cap, breed and weight restrictions, the difference between a service animal and an emotional support animal, the single federal rule that an assistance animal is not a pet, the documentation you may and may not request, New Hampshire’s own misdemeanor for faking a service animal, when you may deny a specific animal, how pet damage and deposits work at move-out, and a step-by-step compliant process for both landlords and tenants. Where the analysis touches deposits, the details ride on the New Hampshire security deposit laws, and for the difference between the two animal categories see our guide to the difference between a service animal and an ESA for landlords.

Because the housing analysis turns on one distinction, the safest posture for a landlord is to run two separate tracks: a written pet policy for actual pets, and a reasonable-accommodation process for every assistance-animal request. The strongest position for a tenant is to know that a service animal or emotional support animal cannot be charged a pet deposit, a pet fee, or pet rent, and cannot be met with a breed or weight limit. Treat every figure and rule here as a starting point and verify the current law before you charge, pay, or dispute anything.

Before the New Hampshire-specific rules, a landlord must understand that assistance-animal law is primarily federal. Three statutes create overlapping obligations for every rental owner, and none can be overridden by a state statute, a city ordinance, an association covenant, or a lease clause. State law can add protection on top of federal law, but it cannot subtract from it.

The Fair Housing Act

The federal Fair Housing Act prohibits disability discrimination in housing, including through a refusal to make a reasonable accommodation. It is the primary source of emotional-support-animal protection and reaches virtually all rental housing — apartments, single-family rentals, condominiums, and most larger owner-occupied buildings. Its core command is simple: a landlord must make reasonable accommodations in rules, policies, practices, or services when they are necessary to give a person with a disability an equal opportunity to use and enjoy a dwelling. Waiving a no-pet policy for a verified assistance animal is the quintessential reasonable accommodation.

The Americans with Disabilities Act

The Americans with Disabilities Act covers service animals — task-trained dogs, and in some cases miniature horses — in places of public accommodation, such as a rental office lobby, a leasing tour area, and a pool or gym open to the public. It does not govern emotional support animals; the Act’s definition of service animal specifically excludes an emotional-support-only animal. In a rental, the individual dwelling units are governed by the Fair Housing Act instead, which protects both service animals and emotional support animals through the reasonable-accommodation framework.

Section Five-oh-four of the Rehabilitation Act

Section five-oh-four of the Rehabilitation Act prohibits disability discrimination by programs that receive federal financial assistance. It applies to public housing, Housing Choice Voucher properties, tax-credit properties, and any housing that has received federal housing funding. Its standards often parallel the Fair Housing Act and occasionally go further. Federal fair-housing guidance — most importantly the Department of Housing and Urban Development’s assistance-animal notice issued in twenty twenty — remains the controlling reference on how to evaluate an assistance-animal request, what documentation is and is not permissible, and how to handle a request for an animal that does not meet the service-animal definition.

The Fair Housing Act’s reach is broad but not unlimited. It exempts an owner-occupied building of four or fewer units where the owner rents without an agent — the so-called Mrs.-Murphy exemption — and a single-family home rented by an owner who owns no more than three such homes and uses no broker. These exemptions are narrower than most landlords assume, and they do not switch off the state fair-housing law. In New Hampshire, the New Hampshire Law Against Discrimination operates alongside the federal Fair Housing Act and covers some housing that federal law does not, so a small landlord should not assume a federal exemption lets them refuse an assistance animal.

Pet deposits, pet fees, and pet rent are the most common points of daily confusion between landlords and tenants, and the single most common reason tenants file fair-housing complaints. The rules break into two very different tracks depending on whether the animal is a pet or an assistance animal.

The Security-Deposit Baseline in New Hampshire

New Hampshire’s overall security-deposit framework caps the amount a landlord may collect at the greater of one hundred dollars or one month’s rent under Revised Statutes chapter five forty-A, section six. Money collected up front — no matter what the landlord calls it — is generally treated as part of that security deposit under state law. Certain rentals fall outside the statute’s coverage, including a single-family home and a small owner-occupied building where the owner lives on site, so the first question is always whether the cap applies to your particular building at all.

New Hampshire Pet Deposit Rules

Where the cap applies, it generally applies to all deposits combined, so a pet deposit for an actual pet is folded into that single number rather than added on top of it. Pet-specific charges are not separately regulated by state statute, so the dollar amounts New Hampshire landlords actually charge track the local rental market rather than any statutory figure. As a market norm, and not a legal entitlement, a New Hampshire pet deposit commonly runs from about two hundred to five hundred dollars per pet in smaller markets and can reach seven hundred fifty dollars or more in higher-rent metros. Whichever structure a landlord chooses, two rules govern: the total held up front cannot exceed the state cap where the cap applies, and the lease must clearly identify what the charge covers and whether it is refundable.

Pet Rent and Nonrefundable Fees

Pet rent is a separate concept from a pet deposit. A pet deposit is a one-time sum held against future damage; pet rent is an ongoing monthly fee paid with rent. New Hampshire law does not cap pet rent, and as a market norm it commonly runs from about twenty-five to seventy-five dollars per month per pet, higher in some urban buildings. Because pet rent is ongoing income rather than held money, it generally does not count toward the security-deposit cap. Whether a landlord may keep a genuinely nonrefundable pet fee depends on how New Hampshire treats up-front charges; the safest structure is a refundable pet deposit within the cap plus a modest, clearly disclosed cleaning fee tied to a specific end-of-tenancy purpose. A deposit simply labeled nonrefundable, without more, is often unenforceable under state deposit rules. The mechanics of collecting and returning any lawful deposit follow the New Hampshire security deposit laws.

Breed restrictions are among the most aggressively litigated parts of rental pet policy. Three layers interact: state treatment of local breed-specific ordinances, a private landlord’s own pet policy, and the absolute overlay that a breed or weight limit cannot be applied to a verified assistance animal.

Private Landlord Breed and Weight Policies

New Hampshire has no statewide breed preemption, and a private landlord may generally impose breed restrictions on ordinary pets. Common restrictions target pit-bull types, Rottweilers, Doberman Pinschers, German Shepherds, Akitas, Chows, wolf hybrids, and sometimes large breeds or specific weight classes. Landlords typically cite an insurance carrier’s requirements as the rationale, and an insurance-based breed policy is legitimate when the insurer actually excludes coverage for the breed. A weight limit — no pets over a set number of pounds — stands on the same footing as a breed limit for ordinary pets.

The Assistance-Animal Exception Is Absolute

No breed, size, or weight restriction may be applied to a verified assistance animal. Federal fair-housing guidance is clear and consistent: a landlord cannot categorically refuse a specific breed when the animal is serving as an emotional support animal or a service animal, and a blanket breed ban applied to an assistance animal is treated as a fair-housing violation. A ninety-pound service dog stays regardless of a building pet-weight cap. The only permitted basis for denying a specific assistance animal is individualized, objective evidence that this particular animal poses a direct threat or would cause substantial physical damage — a documented prior attack, witnessed aggression, or animal-control records tied to that animal — not the assumption that a breed is dangerous as a category.

The emotional-support-animal category is where landlord confusion is highest and where the gap between common belief and the actual rule is widest. An emotional support animal is an animal that alleviates one or more identified symptoms or effects of a person’s disability. It is not a task-trained service animal, it is not limited to dogs, and it is not required to wear a vest, carry an identification card, be registered, or be certified. No such registration exists under federal law, and any website that claims to register an emotional support animal is selling a document with no legal weight.

What Qualifies an Animal as an ESA

Three elements must be present. First, the person seeking the accommodation must have a disability within the meaning of the Fair Housing Act — a physical or mental impairment that substantially limits one or more major life activities. Second, the person must have a disability-connected need for the animal — the animal must do something that reduces the impact of the disability. Third, the accommodation must be reasonable, meaning it does not impose an undue financial or administrative burden or fundamentally alter the landlord’s operations. When the disability or the disability-connected need is not obvious, it must be documented by a reliable third party, most often a letter from a licensed health professional stating that the tenant has a disability and that the animal assists with it. In New Hampshire, the New Hampshire Law Against Discrimination parallels the federal Fair Housing Act and provides a state-law remedy for assistance-animal discrimination in addition to the federal claim. Our emotional support animal guide walks through what a reliable letter looks like.

Species Considerations

The Fair Housing Act does not limit emotional support animals to dogs. Cats, rabbits, small birds, and other common domestic animals are routinely approved. The scope is not unlimited, though: an animal that poses a health risk, is prohibited by local law, or is not commonly kept in a home may be denied on species grounds. A unique animal — a snake, a primate, a reptile, or livestock — faces a higher bar, because the tenant must show a disability-connected need specific to that species that a more conventional animal cannot meet. The bar is meaningfully higher than for a dog or cat, but not impossible.

A service animal is a narrower category than an emotional support animal but carries broader rights of access. Under the Americans with Disabilities Act, a service animal is a dog — or in limited cases a miniature horse — individually trained to do work or perform tasks for a person with a disability. Guiding a person who is blind, alerting a person who is deaf, pulling a wheelchair, reminding a person to take medication, and interrupting a panic episode are tasks. Providing comfort by presence alone is not a task, and that is the bright line between an Americans-with-Disabilities-Act service animal and a Fair-Housing-Act emotional support animal.

The Two Permissible Questions

Under Title twenty-eight of the Code of Federal Regulations, section thirty-six point three oh two, when it is not obvious that an animal is a service animal, staff may ask only two questions: whether the animal is required because of a disability, and what work or task the animal has been trained to perform. That is the entire universe of permissible inquiry. Staff may not ask about the person’s disability, demand medical documentation, require certification, insist on a demonstration of the task, or require the dog to wear a vest or identifying gear. These limits are not discretionary, and a federal claim can be built on a single badly worded question from a leasing-office employee. If the disability and the animal’s role are readily apparent, even those two questions may not be asked.

New Hampshire has its own service-animal chapter, the Revised Statutes chapter one sixty-seven-D, which defines a service animal as a dog individually trained to do work or perform tasks for a person with a disability. Like most state service-animal statutes, it tracks the federal standard on the core access question, though penalties and complaint procedures vary. Where the Americans with Disabilities Act governs the public areas of a rental — the leasing office, tour paths, and amenity areas open to the public — the individual units are governed by the Fair Housing Act, which protects service animals and emotional support animals alike through the accommodation framework.

Nearly every assistance-animal complaint traces back to a procedural failure in the accommodation process rather than a substantive one. A landlord who follows a clean process — even when the answer ends up being yes — rarely faces enforcement. A landlord who shortcuts the process draws complaints even when the underlying decision would have been defensible.

What a landlord may ask for turns on whether the need is obvious. If the disability and the animal’s role are readily apparent — a guide dog harnessed to a tenant who is visibly blind — or already known to the landlord, no documentation may be requested, and asking for paperwork anyway is itself a violation. If the disability is not obvious and not already known, a letter from a reliable third party is the appropriate documentation. Federal guidance treats three sources as reliable by default: a licensed health professional, a government agency that has made a disability determination, and another party in a position to know of the disability-connected need.

The Reliability Standard, Not a Format

Federal guidance evaluates documentation for reliability rather than format, and it takes a skeptical view of a templated, instant-approval online letter. A one-click letter from a provider the tenant has never met, issued minutes after an online form, is facially less reliable than a letter from a provider the tenant has seen over time. A landlord may ask a narrow clarifying question about the therapeutic relationship when a letter has the hallmarks of a purely transactional purchase, but may not demand a diagnosis. Importantly, New Hampshire has no statute regulating the emotional-support-animal-letter industry the way a handful of states do, so there is no state thirty-day-relationship rule or state licensing scheme for these letters; the reliability standard here comes from federal fair-housing guidance, not a New Hampshire statute.

Many states criminalize faking a service animal, and New Hampshire is one of them — but the details matter, because online summaries frequently get the classification and the penalty wrong. Under the New Hampshire Revised Statutes chapter one sixty-seven-D, section eight, it is unlawful to fit an animal with a collar, leash, vest, sign, or harness that represents it as a service animal, or to impersonate a person with a disability, when the animal is not in fact a service animal. Under chapter one sixty-seven-D, section ten, a violation of that chapter is a misdemeanor. The chapter does not set a specific dollar fine for misrepresentation, so a flat figure quoted on a commercial website should be treated with caution and verified against the current statute.

The accommodation duty is strong but not absolute. Federal fair-housing law recognizes a small set of grounds on which a landlord may lawfully deny an assistance-animal request — all narrow, all requiring individualized evidence, and all better documented than most landlords assume.

Direct Threat to Health or Safety

A landlord may deny when the specific animal poses a direct threat to the health or safety of others that cannot be mitigated by another reasonable accommodation. The emphasis is on the specific animal, not the breed, species, or category. Animal-control records showing a bite, multiple written complaints of aggression, a documented altercation, or a veterinary note of known aggression can support a denial; a general statement that a breed is dangerous as a class cannot. The analysis is individualized and current: a single incident years ago with a prior owner is not automatically a present threat, and a landlord who learns of a past incident should ask what happened, what has changed, and what training or management is in place, and document the conversation.

Substantial Physical Damage

A landlord may deny when the animal would cause substantial physical damage to the property of others that cannot be reduced by another reasonable accommodation. Again the standard is individualized. Dogs this size tend to scratch doors is not evidence; this particular animal caused four thousand two hundred dollars in documented damage over six months at its prior residence is.

Undue Burden and Fundamental Alteration

An undue financial or administrative burden is rare in practice; permitting a single emotional support animal almost never creates one, and an insurance-based argument is viable only when the landlord has actually verified that coverage would be denied or substantially increased because of the accommodation. A fundamental-alteration theory is essentially never available for a single assistance animal in a residential unit. The meta-rule is simple: a denial that cannot be stated in specific, individualized, factual terms will not survive an investigation, and a landlord writing a denial in general categories should go back to the interactive process instead.

Assistance-animal denials have been among the top categories of fair-housing complaints nationally for years, and the same errors appear in New Hampshire complaints season after season. Each is avoidable with a disciplined process. Treating an assistance-animal request as a fair-housing matter rather than a pet matter is the single habit that prevents most of them.

The Retaliation Trap

Retaliation is the hidden cost of a reluctantly granted accommodation. A landlord who approves a request and then suddenly enforces lease terms ignored for years, schedules inconvenient inspections, or begins non-renewal talk is building a retaliation case against themselves. Once the accommodation is granted, the relationship must continue on the same terms it would have absent the accommodation. New Hampshire fair-housing enforcers take retaliation seriously, and a pattern the landlord views as coincidental often looks obvious on a timeline. A useful habit worth keeping is re-confirming the accommodation in writing at each renewal so the file stays current, which does not require new documentation.

Planned-community governance adds a second layer of pet rules on top of the landlord-tenant framework. For a landlord who owns a unit in an association-governed community, the interaction between the association’s rules and the Fair Housing Act is a frequent source of confusion — and a frequent source of complaints against the association itself.

The Fair Housing Act applies to a homeowners association, a condominium association, and a cooperative as a housing provider. An association cannot adopt or enforce pet rules that violate the Act, so a breed ban in the covenants, a weight limit, a pet-quantity cap, and a non-refundable pet fee all give way when the animal is a verified assistance animal for a resident with a disability. An association that refuses to modify its rules faces the same liability as a landlord, and often larger exposure because it governs many units.

A rental landlord who owns a unit in such a community is caught between two obligations: the tenant makes an accommodation request the landlord must grant under the Fair Housing Act, while the association’s rules prohibit the breed, weight, or species. The answer is that the landlord grants the accommodation and then, if necessary, supports the tenant in pressing the association for its own accommodation. The association’s duty runs directly to the resident, whether the resident is the owner or the renter. The landlord’s role is to grant the tenant’s request, provide the association with the information the tenant authorizes, and document the response — not to adjudicate the association’s compliance. If the association denies the accommodation, the exposure belongs to the association, not the landlord who granted the request in good faith.

The hardest single conversation in pet-damage landlord-tenant law is the move-out accounting. Pet damage is real, often expensive, and shows up in categories that wear-and-tear law does not forgive — while New Hampshire’s deposit-deduction rules are specific and unforgiving, so a poorly documented pet-damage claim is one of the fastest ways to lose a small-claims case a landlord should have won.

Wear and Tear Versus Damage

Every New Hampshire deposit rule starts from the same principle: a landlord may deduct for damage beyond ordinary wear and tear, but not for wear and tear itself. Pet-caused conditions that almost always count as damage include a urine-saturated subfloor, permanent odor requiring subfloor replacement, carpet shredded through the pad, chewed door frames and molding, and scratched or stained hardwood. Conditions courts often treat as wear and tear include light carpet matting from pet traffic, faint hair in ventilation returns, and minor odor that standard cleaning neutralizes.

Itemize Every Deduction

New Hampshire, like nearly every state, requires the landlord to give the tenant an itemized statement of deductions within a statutory deadline after move-out, separately identifying each deduction, the condition it repairs, and the amount. A lump-sum entry such as pet damage is uniformly rejected in court. The landlord needs line items — for example, replacement of the master-bedroom carpet due to pet-urine saturation at nine hundred forty-five dollars, replacement of the pad at one hundred eighty-five dollars, and sealing of the subfloor at one hundred thirty-five dollars, for a subtotal of one thousand two hundred sixty-five dollars — each supported by a dated move-in and move-out photo inventory and a third-party vendor estimate or invoice.

Assistance Animals and the Damage Question

An assistance animal is exempt from pet deposits and pet fees, but not from liability for damage. A tenant whose emotional support animal saturates the carpet pad and subfloor owes for the damage, deducted from the regular security deposit, exactly as any other tenant would. The accommodation removes the up-front pet-specific charges, not the tenant’s responsibility for what the animal actually breaks. Because the deposit is capped at the greater of one hundred dollars or one month’s rent under Revised Statutes chapter five forty-A, section six, and pet damage frequently exceeds that, a landlord often faces a deposit-plus-some-damage situation at move-out. The cap limits how much tenant money the landlord may hold up front, not the tenant’s total liability; damage above the deposit is still owed, and the landlord collects it through a clean itemization and, if needed, a small-claims filing within the limitations period.

Evicting a tenant over an animal is possible but procedurally delicate, and the margin for error narrows sharply when the animal is, or is claimed to be, an assistance animal. Four categories commonly drive animal-caused evictions in New Hampshire: an unauthorized pet with no accommodation request, an unauthorized animal after an accommodation claim, aggression or nuisance by a permitted animal, and material damage.

The simplest case is an unauthorized pet brought in against a no-pets clause with no accommodation request: the landlord serves the applicable notice to remove the animal, and if the tenant does not cure, files for eviction as ordinary lease enforcement. The analysis changes the moment the tenant claims assistance-animal status. The landlord cannot then treat the animal as an unauthorized pet; the first move is the reasonable-accommodation process, and an eviction cannot advance while a good-faith accommodation request is pending. Only after the landlord has formally denied the accommodation on defensible grounds and the tenant has declined to remove the animal can an eviction proceed — and even then it invites a retaliation counter-claim.

Where a permitted animal becomes aggressive or causes a nuisance, eviction requires individualized evidence of that specific animal’s behavior — multiple complaints, animal-control reports, dated incidents with witnesses — and for an assistance animal the direct-threat test controls. Where the animal causes ongoing material damage, the ground is the tenant’s failure to prevent or repair the damage, not the animal’s existence; assistance-animal status does not shield the tenant from liability for damage. The underlying eviction machinery — notice periods, filing courts, and tenant defenses — is the same as for any other case; for the full framework see the New Hampshire eviction notice laws guide.
