Pet Deposits, Pet Rent & ESA Rules in New Mexico 2026
State pet-deposit treatment, federal Fair Housing Act assistance-animal rules, and what New Mexico landlords can and cannot ask.
New Mexico gives you wide latitude over ordinary pets and almost none over assistance animals, and the line between the two is where most landlords get into trouble. You can ban pets, cap their size, or charge pet rent - but the moment a tenant's animal is a service animal or an emotional support animal (ESA), a different rulebook takes over, and it is largely federal.
New Mexico has its own Service Animal Act (NMSA 1978 Sections 28-11-1.1 et seq.) governing public access, but no standalone ESA housing statute. Housing accommodation rights flow from the federal Fair Housing Act and the New Mexico Human Rights Act. This page separates the three categories - pets, service animals, and ESAs - so you know exactly what you may charge, what you must waive, and what you may ask.
How New Mexico Treats Pet Deposits
For leases under 1 year, security deposit capped at 1 month's rent. Pet deposits count toward this cap. For leases of 1 year+, no statutory cap.
Ordinary pets: you set the terms
For a genuine pet - not a service or assistance animal - New Mexico leaves the decision to you. You may adopt a no-pets policy, restrict breeds or weight, cap the number of animals, and charge pet rent or a pet deposit. There is no separate 'pet deposit' statute; any refundable deposit you collect counts toward the deposit limits in NMSA 1978 Section 47-8-18.
Those limits matter. For a lease of less than one year, your total security deposit cannot exceed one month's rent. For a lease of one year or longer, the deposit must simply be 'reasonable.' A refundable pet deposit on a short-term lease therefore eats into your one-month ceiling; a nonrefundable pet fee or monthly pet rent is the usual workaround, but spell it out clearly in the lease. Whatever you hold, you must account for and return it within 30 days after the tenancy ends.
Service animals: dogs and miniature horses only
Under the New Mexico Service Animal Act, a 'qualified service animal' is narrow: a service dog or a service miniature horse individually trained to do work or perform tasks for a person with a disability. Comfort, companionship, and emotional support do not count as a task - those animals are ESAs, covered in the next section.
A service animal is not a pet, so your no-pets policy, breed limits, and pet fees do not apply to it. New Mexico also goes a step further than the ADA: service animals in training get the same access rights as fully trained ones. When it is not obvious that an animal is a service animal, you may ask only two questions - is the animal required because of a disability, and what work or task is it trained to perform. You may not demand proof, paperwork, or a demonstration of the task.
Emotional support animals: a housing accommodation, not a pet
New Mexico has no ESA-specific housing law, so here you follow the federal Fair Housing Act and the New Mexico Human Rights Act. Under the FHA, an ESA is an assistance animal, and you must grant a reasonable accommodation even if your property is pet-free. That means waiving no-pets rules, pet fees, pet deposits, and breed or size restrictions for a properly documented ESA. The animal is not covered by the two-question service-animal script - it is covered by the accommodation process instead.
You are not defenseless. You may request reliable documentation that the tenant has a disability-related need for the animal (for a non-obvious disability), but you cannot demand detailed medical records or a specific diagnosis. You may still hold the tenant financially responsible for actual damage the animal causes, and you may deny an accommodation if the specific animal poses a direct threat to others or would cause substantial physical damage that no reasonable accommodation can reduce - based on the animal's actual conduct, not its breed.
When a request is fake: misrepresentation penalties
New Mexico is one of the states that criminalizes faking a service animal. Under NMSA 1978 Section 28-11-6, knowingly presenting an animal as a qualified service animal when it is not is a misdemeanor, punishable under Section 31-19-1 - up to a $1,000 fine and/or up to (less than) one year in county jail.
That statute is aimed at public-access fraud, not at your housing accommodation decisions, so do not treat it as a tool to reject ESA requests. The practical takeaway: verify need through the proper accommodation process, keep written records of what you asked and received, and let enforcement of the criminal provision rest with the authorities rather than your own judgment call.
A clean process that keeps you compliant
Build one consistent workflow. For any animal, first ask: is this a service animal, an ESA, or a pet? If service animal, apply the two-question limit and stop charging pet fees. If ESA, run it as a reasonable-accommodation request, request need documentation only when the disability is not obvious, and waive pet-related charges. If a pet, apply your written pet policy and keep deposits inside the Section 47-8-18 limits.
Document every step, respond to accommodation requests promptly and in writing, and never deny based on breed alone. Hold assistance-animal owners to the same damage and conduct standards as everyone else - that is where your protection lies. When a disability or documentation question is genuinely close, the New Mexico Governor's Commission on Disability (505-476-0412) is a useful resource before you make a decision you cannot easily reverse.
The Cost of Mishandling a New Mexico ESA Request
The most common mistake in New Mexico ESA cases is responding with a flat denial, "no pets means no pets", instead of engaging in the interactive process. The interactive process is itself a substantive duty. A landlord who refuses to consider the request, demands more documentation than HUD permits, or imposes a pet fee on an accepted assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied on its merits.

Frequently Asked Questions
Can a New Mexico landlord charge a pet deposit for an ESA or service animal?
No. Under the federal Fair Housing Act, service animals and emotional support animals are assistance animals, not pets, so you must waive pet deposits, pet fees, and pet rent for them. You may still charge for actual damage the animal causes. Pet deposits are allowed only for ordinary pets, and they count toward the deposit limit in NMSA 1978 Section 47-8-18.
What questions can I ask about a service animal in New Mexico?
When it is not obvious, you may ask only two questions: is the animal required because of a disability, and what work or task is it trained to perform. You cannot demand documentation, certification, or a demonstration. Note that emotional support animals are not covered by this two-question rule - they go through the reasonable-accommodation process instead.
Does New Mexico have a separate ESA housing law?
No. New Mexico has no standalone ESA housing statute. ESA housing rights come from the federal Fair Housing Act and the New Mexico Human Rights Act, which require reasonable accommodation. The state Service Animal Act (Sections 28-11-1.1 et seq.) governs public access and covers only service dogs and miniature horses, not ESAs.
Can I refuse an emotional support animal in a no-pets building?
Generally no. A no-pets policy does not override the duty to make a reasonable accommodation for a documented ESA. You may deny only in limited cases - for example, if the specific animal poses a direct threat to others or would cause substantial damage that no reasonable accommodation can address, based on the animal's actual conduct rather than its breed or size.
What is the penalty for misrepresenting a service animal in New Mexico?
Under NMSA 1978 Section 28-11-6, knowingly presenting an animal as a qualified service animal when it is not is a misdemeanor, punishable under Section 31-19-1 by up to a $1,000 fine and/or up to (less than) one year in county jail. This applies to public-access fraud and should not be used as a shortcut to reject housing accommodation requests.
How much can I charge as a deposit if a tenant has a regular pet?
For a lease of less than one year, your total security deposit - including any refundable pet deposit - cannot exceed one month's rent under NMSA 1978 Section 47-8-18. For a lease of one year or longer, the deposit must be reasonable. Whatever you hold, you must return it and provide an accounting within 30 days after the tenancy ends. Many landlords use nonrefundable pet fees or monthly pet rent to stay within the cap.
