## The one place New Mexico describes the document

Most states that say anything about emotional support animals say it in a
statute about who may sign a letter. New Mexico has no such statute. What it
has instead is a procedural rule, written by the agency that would
investigate a housing complaint, about what that agency expects a
complainant to produce.

**9.1.1.8(F)(3) NMAC**, under the heading *Jurisdiction*:

> "When a disability or serious medical condition is alleged in the complaint, the complainant
> **must offer evidence of the disability or serious medical condition** during the course of the
> investigation. Evidence documenting a disability or serious medical condition may be provided by
> the **written certification of a physician or other appropriate medical authority** unless the
> existence of the disability or serious medical condition is not a matter in dispute."

That is the New Mexico Human Rights Bureau, in its own regulation,
describing a written certification from a clinician. It is not marketing
language and it is not a form the Bureau sells. It is the state saying which
kind of paper answers the question it will ask.

## Read the sentence around it before you rely on it

Two limits, both of them in the text.

The rule governs **an investigation**, not a leasing office. It tells the
Bureau what will satisfy it once a complaint is open. Nothing in
9.1.1.8(F)(3) gives a Las Cruces property manager the right to demand a
diagnosis, a treatment history or a particular form at the counter when you
make the request.

And it puts the evidentiary burden squarely on the tenant, "the complainant must offer evidence."
There is no provision anywhere in 9.1.1 NMAC that makes a landlord prove the negative. If the
disability is disputed, the person who has to answer for it is you.

Take those together and the rule is doing something quietly useful. It tells
you, before anything goes wrong, what the state's own adjudicator will want
if things do go wrong. Very few states put that in writing at all.

## The market it applies in

Las Cruces rents 20,958 of its 47,517 occupied homes: **44.1 percent** on
the 2020–2024 American Community Survey five-year estimate, the
third-highest renter share among New Mexico's twenty largest cities, behind
Portales at 52.4 percent and Gallup at 47.9. Only Albuquerque houses more
renting households.

Median gross rent is **$974**, ninety-three dollars below the $1,067 New
Mexico figure. The 2024 Census estimate puts the city at 116,998 people,
second in the state and about a fifth the size of Albuquerque.

That combination, a large renting population paying below-median rent, is
why a monthly pet charge matters more here than the dollar amount suggests,
and why the request is worth making properly the first time.

## What "appropriate medical authority" means in practice

The phrase is not defined. Neither 9.1.1.7 NMAC's definitions section nor
the Human Rights Act itself tells you who counts, and New Mexico has enacted
no list of qualifying professions of the kind some other states have.

Two things follow.

**The floor is licensure and relevance.** "Physician **or other appropriate medical authority**"
is deliberately broader than "doctor," which is how a licensed psychologist, a licensed
independent social worker or a licensed professional clinical counsellor comes within it. What
"appropriate" is carrying is the fit between the professional and the condition alleged — an
authority appropriate to a mental-health impairment is somebody licensed to assess mental health.

**The ceiling is that a certification has to certify something.** The word in the rule is not
"letter" or "note." It is *certification*, and a certification records a finding. A document that
says a tenant reports feeling calmer around their dog has not made one. A document that says a
licensed clinician assessed this person, identified an impairment and formed a view about what
that impairment needs, has.

## And the provision the certification supports is federal

Here is the part that surprises people. The Bureau's own filing rule, 9.1.1.8(D), requires a
complaint to state, among other things, "the particular provisions of the state or federal
statutes … upon which the complainant bases the claim." So the form itself asks which law you are
standing on.

For an assistance-animal accommodation in a Las Cruces rental, the honest answer names a federal
provision. New Mexico's Human Rights Act contains no reasonable-accommodation duty in housing:
§ 28-1-7(J), the only accommodation duty in the Act, binds "any employer," and both § 28-1-2(V)
and 9.1.1.7(X) NMAC define the term for employment purposes. The duty to make an exception to a
no-pets rule comes from 42 U.S.C. § 3604(f)(3)(B) — "a refusal to make **reasonable accommodations
in rules, policies, practices, or services**, when such accommodations may be necessary to afford
such person **equal opportunity to use and enjoy a dwelling**."

State law still gives you § 28-1-7(G)(2), which reaches discrimination "in the terms, conditions
or privileges" of a rental because of a physical or mental disability, and it gives you the Bureau
and three hundred days under § 28-1-10(A) in which to reach it. The certification described in
9.1.1.8(F)(3) is what proves the disability element of either claim.

## One document, two audiences

The document you would need in an investigation is the same document that
should have gone to the landlord in the first place. That is the whole
argument for doing it in the right order.

A tenant who obtains a written clinical certification before making the
request has something to attach when the manager asks what the animal is
for, and has already satisfied 9.1.1.8(F)(3) on the day the Bureau asks the
same question months later. A tenant who tells the leasing office they have
anxiety and nothing more has neither.

## Where southern New Mexico gets a clinician

Start with anybody already treating you. A letter from a clinician with a
real record of your care is stronger than anything a stranger can write, and
it costs nothing extra. The friction is availability: New Mexico's
specialist mental-health capacity concentrates in Albuquerque and Santa Fe,
Doña Ana County's independent practices carry waitlists, and a primary-care
provider may decline to make a disability finding that sits outside what
they treat.

Community services here are real and worth knowing: the Community Action
Agency of Southern New Mexico runs out of Foothills Road, New Mexico Legal
Aid keeps an office on East Montana, and the Mesilla Valley Public Housing
Authority serves Las Cruces and Doña Ana County from South San Pedro Street.
What none of them does is write a disability certification.

Where the treating route is closed, an evaluation by a licensed provider is
the same assessment arranged on purpose. Somebody licensed examines whether
an impairment substantially limits a major life activity and whether this
animal answers it, then certifies the conclusion in writing, or declines,
which happens, and which is precisely why a certification from a real
assessment carries weight that a purchased certificate never does.

New Mexico told you what it wants to see. The only question left is who is
going to sign it.

## What Las Cruces landlords can and cannot do

**Cannot:**
- May not refuse to rent, or refuse to negotiate, because of a physical or mental disability: NMSA 1978, § 28-1-7(G)(1).
- May not discriminate because of disability in the terms, conditions or privileges of the rental or in the facilities and services provided with it, § 28-1-7(G)(2). This is the state provision a charge attached to an assistance animal is met by.
- May not use the three-day substantial-violation route over an animal. § 47-8-3(V)'s closed list does not include one. The route is a written seven-day notice and cure under § 47-8-33(A), served within thirty days of the breach or knowledge of it.
- May not raise at trial any ground outside the written notice, § 47-8-33(G).
- May not retaliate by raising rent, cutting services or bringing an action for possession within six months of a fair housing complaint made to a government agency, on pain of liability for two times the monthly rent: §§ 47-8-39(A)(4), 47-8-48(C).

**Can:**
- Must make a reasonable accommodation in rules, policies, practices or services where necessary to afford equal opportunity to use and enjoy the dwelling, but under 42 U.S.C. § 3604(f)(3)(B) and 24 C.F.R. § 100.204, not under New Mexico law, which imposes that duty only on employers.
- May adopt a no-pets rule only where it is reasonably related to its purpose and applied to all residents fairly, § 47-8-23(B)–(C), and may impose one mid-tenancy only with reasonable notice and only where it does not work a substantial modification of the bargain: § 47-8-23(F).
- May demand only a reasonable deposit, and only to recover damage caused to the premises, § 47-8-18(A). Under a lease shorter than a year the deposit may not exceed one month's rent; under an annual lease anything above one month's rent obliges the owner to pay passbook-rate interest.
- Is outside the state Act only in the narrow cases § 28-1-9 describes: the single-family exemption at (A), with its reservations and its condition that no prohibited advertisement was used, and the separate owner-occupied exemption at (D) for four families. The federal Fair Housing Act draws its own exemptions and is unaffected.

## Frequently asked questions

### What evidence of a disability does the New Mexico Human Rights Bureau expect?

9.1.1.8(F)(3) NMAC answers directly: a complainant alleging a disability "must offer evidence of the disability or serious medical condition during the course of the investigation," and that evidence "may be provided by the written certification of a physician or other appropriate medical authority." It is the state agency naming the kind of paper it wants, inside its own regulation rather than in guidance that can be withdrawn.

### Who counts as an "appropriate medical authority" in New Mexico?

Nobody has said. The phrase is undefined in the rule, in 9.1.1.7 NMAC's definitions and in the Human Rights Act, and New Mexico has passed no statute listing which professions may write a housing letter. What the words themselves suggest is a floor of licensure plus fit: "physician or other appropriate medical authority" is deliberately wider than "doctor," and appropriateness is measured against the condition being alleged.

### Can my landlord in Las Cruces demand everything the bureau would want?

No. 9.1.1.8(F)(3) NMAC sits under the heading Jurisdiction and describes what satisfies the bureau once a complaint is open and under investigation. Nothing in it authorises a housing provider to require a diagnosis, a treatment history or a particular form when a tenant first makes a request. The two moments are different, and the rule speaks only to the later one.

### Is a short note saying my dog helps my anxiety enough?

It is weaker than what the rule describes. The word in 9.1.1.8(F)(3) NMAC is certification, and a certification records a finding somebody qualified has made. A note reporting what a patient says they feel has not made one. A document stating that a licensed clinician assessed this person, identified an impairment and formed a view about what that impairment requires has, and it is that second kind the bureau's language contemplates.

### What if my landlord does not actually dispute that I have a disability?

The rule anticipates that. Its closing words are "unless the existence of the disability or serious medical condition is not a matter in dispute," so the evidentiary requirement falls away where the point is conceded. The practical difficulty is that concessions rarely survive a dispute that escalates, and a tenant who prepared nothing has no way to recover the position once the landlord's position hardens.

### Does New Mexico require the provider to be licensed in New Mexico?

No state statute says so. Some states have written in-state licensure or a prior in-person care requirement; New Mexico has enacted nothing of the kind, and 9.1.1.8(F)(3) NMAC speaks only of a physician or other appropriate medical authority. That makes it a credibility question rather than a compliance one, and a provider licensed to practise where the tenant lives is the version of the document that is hardest to argue with.

### How does Las Cruces compare with the rest of New Mexico for renting?

It is one of the state's genuinely renter-heavy cities. 20,958 of 47,517 occupied homes are rented, 44.1 percent on the 2020-2024 American Community Survey five-year estimate, well above the 30.0 percent statewide share and third among the twenty largest cities behind Portales and Gallup. Median gross rent of $974 runs ninety-three dollars below the $1,067 state figure.
