## A small rental market on a two-country border

Sunland Park sits in Doña Ana County at the corner where New Mexico, Texas
and Mexico meet. The city's own site calls it a growing binational community
at that edge. Functionally it belongs to the El Paso, Texas metro rather
than to Las Cruces, which is the single most useful thing to know about
renting here.

The 2024 Census estimate puts the city at 18,185 people, thirteenth in New
Mexico. Of its 5,557 occupied homes, **1,140 are rented, 20.5 percent** on
the 2020–2024 American Community Survey five-year estimate. Only Rio Rancho,
at 17.8 percent, has a smaller renter share among the state's twenty largest
places; the statewide figure is 30.0 percent. Median gross rent is **$920**,
below the $1,067 New Mexico median.

A thin rental market means fewer professionally managed buildings and more
individual owners writing their own leases. It also means a tenant asking
for an exception to a no-pets rule is often the first person that owner has
heard ask. So it matters a great deal which law the request is actually made
under.

## The subsection everyone assumes New Mexico has

Almost every state around New Mexico writes a reasonable-accommodation duty
into its own fair housing law. New Mexico's Human Rights Act contains
exactly one accommodation duty, and this is all of it: **§ 28-1-7(J)**:

> "It is an unlawful discriminatory practice for: … **any employer to refuse or fail to
> accommodate a person's physical or mental disability or serious medical condition, unless such
> accommodation is unreasonable or an undue hardship**"

**Any employer.** Not any owner, not any landlord, not any person. The subsection sits in a list
whose other parts do cover housing, and it changes subject at the word "employer."

The Act's own definition confirms the reading rather than rescuing it. **§ 28-1-2(V)** defines
reasonable accommodation as modification of "**the work environment, work schedule, work rules
or job responsibilities**" to enable "**an employee to perform the essential functions of the
job**." And the Human Rights Bureau's regulation, **9.1.1.7(X) NMAC**, opens the definition with
the scope written in:

> "'Reasonable accommodation' means, **for employment purposes**, such modifications or
> adaptations of the work environment, work schedule, work rules or job responsibilities …"

Statute and rule agree with each other. **No page should tell you that New
Mexico law requires your landlord to make a reasonable accommodation,
because it does not say that anywhere.**

## So the duty comes from outside the state

That is not the disaster it sounds like. It relocates the argument rather
than ending it.

**42 U.S.C. § 3604(f)(3)(B)**, the federal Fair Housing Act, makes discrimination include:

> "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**"

Its regulation, 24 C.F.R. § 100.204, uses the waiver of a no-pets rule for
an assistance animal as the worked example of what that duty requires. The
federal act binds a Sunland Park landlord directly. It does not need New
Mexico's permission, and New Mexico cannot subtract from it.

Practical consequence: **cite the federal provision, not a state one.** A
request in Doña Ana County that leans on the New Mexico Human Rights Act for
the accommodation itself is leaning on a subsection about employers, and a
landlord's lawyer will say so.

## What state law does still give you

Two things, and they are worth having.

**§ 28-1-7(G)(1)** makes it unlawful for any person to refuse to rent a housing accommodation
because of physical or mental disability. **§ 28-1-7(G)(2)** reaches discrimination "**in the
terms, conditions or privileges**" of a rental on the same ground, which is the route by which
a charge attached to an assistance animal comes off under state law. Both come with a state
agency to complain to, the Human Rights Bureau of the Labor Relations Division, the body
§ 28-1-2(D) names.

Both also carry a proviso, repeated at the end of every housing subsection:

> "provided that the physical or mental disability is **unrelated to a person's ability to
> acquire or rent and maintain** particular real property or housing accommodation"

The Bureau's rule glosses it at 9.1.1.7(W) NMAC as a disability that "does not limit that
person's ability to fulfill the obligations of occupancy, tenancy, ownership or credit
responsibilities." It is not a rule about the animal's behaviour and it is not New Mexico's
version of the federal direct-threat defence. The state has no housing direct-threat provision
of its own. It is a qualifier on the protected class, and it describes the ordinary tenant.

## The two findings the federal duty needs

Strip § 3604(f)(3)(B) to its load-bearing parts and there are two.

**One: a disability.** Federally, the definition is at 24 C.F.R. § 100.201; New Mexico's own
parallel, § 28-1-2(O), reads "a physical or mental impairment that substantially limits one or
more of a person's major life activities," and § 28-1-2(P) lists those activities as caring for
one's self, manual tasks, walking, seeing, hearing, speaking, breathing, learning and working.

**Two: a connection.** The accommodation has to be one that "may be necessary" for equal
opportunity to use and enjoy the dwelling. Not convenient. Not preferred. Necessary in the sense that without it
this tenant does not get the same use of the home as anyone else.

Neither finding is one you make about yourself, and neither is one a landlord makes. Both are
clinical judgments, which is why the whole request rests on a document. The Human Rights
Bureau's own rule says as much: **9.1.1.8(F)(3) NMAC** puts the burden of evidencing a
disability on the complainant and names "the written certification of a physician or other
appropriate medical authority" as the way to carry it.

## What the same federal rules let a landlord ask

The duty comes with limits on the enquiry, in the same part of the code.
**24 C.F.R. § 100.202(c)** makes it unlawful to ask whether an applicant has
a handicap, or about its nature or severity, outside a short list of
exceptions. What a housing provider may do is ask for information
establishing that a person is eligible for a benefit available to persons
with disabilities, which is what a request for documentation is.

The practical line falls in a usable place. A landlord may ask for something
that establishes the two findings. A landlord is not entitled to your
diagnosis, your notes, or your treatment history, and the Human Rights
Bureau's evidence rule does not change that either: 9.1.1.8(F)(3) NMAC
governs what the **Bureau** wants during an **investigation**, not what a
leasing office may demand at the counter.

## Getting the findings made from a border town

Ask your own clinician first if you have one. A provider who already treats
you can make both findings from knowledge rather than from an interview, and
that is the strongest document available anywhere.

Then weigh the geography honestly, because Sunland Park's is unusual. The
nearest large concentration of providers is across the state line in El
Paso, not in New Mexico, and which state a provider holds a licence in is a
question worth asking before the appointment rather than after the letter is
written. Inside New Mexico, Doña Ana County capacity is limited and
specialist practice is concentrated hundreds of miles north in Albuquerque
and Santa Fe.

A licensed evaluation is the same assessment, arranged on purpose: a
licensed professional determines whether a disability exists and whether
this animal is necessary in this home, and issues the documentation where
the assessment supports it, or declines, which happens, and is the reason
the document means anything when it does not.

New Mexico gave the accommodation duty to employers. Everything protecting
your animal in a Sunland Park apartment arrives from outside the state, and
it arrives asking for two findings that only a professional can make.

## What Sunland Park 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

### Does the New Mexico Human Rights Act make my landlord accommodate my disability?

It does not. Subsection J of § 28-1-7 is the Act's only accommodation duty and it is addressed to any employer. The definition at § 28-1-2(V) is written around the work environment, work rules and job responsibilities, and 9.1.1.7(X) NMAC states the same definition to apply for employment purposes. A request that rests on the state Act for the accommodation itself is resting on an employment provision.

### Then what do I put in the letter to my landlord?

The federal provision. 42 U.S.C. § 3604(f)(3)(B) makes discrimination include a refusal to make reasonable accommodations in rules, policies, practices or services when they may be necessary to afford equal opportunity to use and enjoy a dwelling, and 24 C.F.R. § 100.204 implements it. Naming the right source is not a formality here, because the state alternative does not say what a reader might assume it says.

### What does the federal duty actually require me to establish?

Two findings. That there is a disability: an impairment substantially limiting a major life activity, the same shape as the state definition at § 28-1-2(O) with its list of major life activities at § 28-1-2(P). And that the accommodation may be necessary for equal opportunity to use and enjoy the home, which is a link between the disability and this animal. Neither is something a tenant or a landlord decides.

### Sunland Park is inside the El Paso metro. Does Texas law govern my apartment?

No. The dwelling sits in Doña Ana County, New Mexico, so New Mexico's Uniform Owner-Resident Relations Act and the New Mexico Human Rights Act are the state law over the tenancy, whichever side of the line you work or shop on. The federal Fair Housing Act applies on both sides and does not change at the state boundary.

### The closest providers are in El Paso. Is a letter from one of them usable here?

Ask the provider directly which state or states they are licensed in and whether they write documentation for a New Mexico tenancy, and get the answer before the appointment rather than after the letter. It is a real question for a border city and it is the provider's to answer. What matters at the far end is that someone qualified made a finding about you, and that the finding is written down.

### If the state has no accommodation duty, is the state claim worth anything?

Yes, for what it does cover. Section 28-1-7(G)(1) reaches a refusal to rent because of a physical or mental disability and § 28-1-7(G)(2) reaches discrimination in the terms, conditions or privileges of the tenancy, which is how a charge attached to the animal is challenged under state law. Both come with a state agency to file with. What they do not do is compel an exception to a rule.

### Almost four homes in five here are owner-occupied. How does that affect a request?

It shapes who you are asking. With 1,140 rented homes out of 5,557 the market is small and weighted toward individual owners rather than managed complexes, so the person reading your request may never have handled one. That is an argument for a short written request, an accurate description of the animal, and documentation attached rather than promised.
