New Mexico Tenant Screening Laws: What Landlords Can and Cannot Do
New Mexico ties the deposit cap to the lease length and adds an interest rule, but does not cap screening fees. The FCRA and fair housing law govern who you approve. Here is how to screen legally in 2026.
Tenant screening in New Mexico is governed lightly by state statute and heavily by federal law. The Uniform Owner-Resident Relations Act sets the deposit rules, but it says little about how you evaluate an applicant – which makes the federal Fair Credit Reporting Act and fair housing law the real rulebook.
This guide covers what you may screen, what you can charge, and the deposit rules under NMSA 47-8-18. If you are new to the mechanics, our overview of how to screen tenants step by step pairs well with the New Mexico-specific points below.

Key Takeaways: New Mexico Tenant Screening Laws
- No application-fee cap. New Mexico does not limit screening fees, but they must be reasonable and tied to the actual cost of the report.
- The deposit cap depends on the lease. For agreements under one year, no more than one month’s rent; for one year or longer, the deposit must be reasonable.
- Larger deposits earn interest. If the deposit exceeds one month’s rent, NMSA 47-8-18 requires the landlord to pay the tenant annual interest.
- Return within thirty days with an itemized list, and never deduct for normal wear and tear.
What New Mexico Law Lets You Screen
New Mexico gives landlords broad authority to evaluate an applicant. With written permission you may obtain a consumer report covering credit, rental and payment history, employment and income, and public records such as criminal convictions and civil judgments, and you may decline applicants who fail your written standards.
Because New Mexico regulates so little of the screening process, consistency is the safeguard: write your criteria down and apply them identically to every applicant. Our guide to the minimum credit score for renting explains how to set a threshold that screens for risk without screening out a protected class.
Application Fees in New Mexico: No Cap
New Mexico sets no maximum on a tenant application or screening fee. The practical limits are reasonableness and consistency: tie the fee to the actual cost of the report and charge the same amount to every applicant.
Uneven fees, or fees collected without genuine screening, draw fair housing scrutiny even where no cap exists. Treat the fee as part of a documented, even-handed process.
The deposit rules are the regulated part
New Mexico leaves the fee to you, but NMSA 47-8-18 ties the deposit cap to the lease length, requires interest on larger deposits, and sets a thirty-day itemized return.
Security Deposits Under NMSA 47-8-18
New Mexico ties the deposit ceiling to the length of the lease. For a rental agreement of less than one year, the landlord may not demand a deposit greater than one month’s rent. For an agreement of one year or longer, there is no fixed statutory maximum, but the deposit must be reasonable, and if it exceeds one month’s rent the landlord must pay the tenant annual interest at the passbook rate.
After the lease ends, the landlord has thirty days to return the deposit with an itemized list of deductions, and may not charge for normal wear and tear. Our deeper look at New Mexico security deposit laws covers permitted deductions and the interest rule.
New Mexico Fair Housing and Protected Classes
The New Mexico Human Rights Act prohibits housing discrimination on the basis of race, religion, color, national origin, ancestry, sex, sexual orientation, gender identity, spousal affiliation, and disability, broader than the federal floor. New Mexico does not add source of income as a statewide protected class.
That means a landlord is generally not required by state law to accept a housing voucher, though uniform treatment of every applicant remains the rule. For the federal baseline, see our Fair Housing Act guide for landlords.
Criminal History, Credit, and Eviction Records
A criminal record can be a lawful basis to decline in New Mexico, but a blanket no-record policy is the most common fair housing trap. HUD’s 2016 guidance treats criminal-records screening under a disparate-impact lens, so a flat ban can violate the federal Fair Housing Act even without intent. Use an individualized assessment tied to the offense, how recent it is, and safety.
Credit history and prior evictions are cleaner when your standard is objective and consistently applied. You can read how eviction filings arise on our New Mexico eviction notice laws page. Decide your criteria in advance and apply them the same way every time.
The FCRA: Consent and Adverse Action
When you pull a screening report through a consumer reporting agency, the federal Fair Credit Reporting Act governs the transaction – and in New Mexico, where state law is largely silent on screening, this is the rule that matters most. You need a permissible purpose and written authorization before ordering the report, and you must send an adverse action notice if the report drives a denial, a higher deposit, or a co-signer demand.
The notice must name the reporting agency, state that it did not make the decision, and explain the applicant’s right to a free copy and to dispute it. Our FCRA compliance guide and the companion walkthrough of the adverse action notice spell out the requirements.
Fair Housing Compliance for New Mexico Landlords
The New Mexico Human Rights Act and the federal Act demand the same discipline, and New Mexico’s broader class list raises the stakes: uniform criteria, uniform application, and documentation showing you treated every applicant by the same yardstick.
Publish your criteria before you advertise, screen every applicant against the identical standard, and keep the file. Consistency is far more persuasive than an after-the-fact explanation.
A Compliant New Mexico Screening Process
Turn the rules into one repeatable sequence. First, publish objective criteria. Second, collect a reasonable, uniform screening fee. Third, get written consent and order the report. Fourth, evaluate every applicant against the identical standard. Fifth, if you decline based on a report, send the adverse action notice promptly – and size the deposit to the lease length, paying interest if it exceeds one month.
Income verification is the step landlords most often shortcut; our guide to verifying tenant income shows how to confirm ability to pay without singling anyone out. Run the same steps for every applicant and your file will tell a clean, consistent story.
Common Mistakes That Create Liability
The recurring New Mexico errors cluster around the deposit. Charging more than one month on a short lease, skipping the interest owed on a larger deposit, deducting for normal wear, or missing the thirty-day itemized return all create exposure. Charging uneven fees and denying an applicant on a report without the FCRA notice round out the list.
One standard, every applicant. New Mexico hands you the freedom to design your own process but pins down the deposit. Build the lease-based cap, the interest rule, the thirty-day return, and a uniform screening rubric into your standard workflow.
Documentation and Recordkeeping in New Mexico
Because New Mexico regulates the screening process so lightly, your records are what prove it was lawful and even-handed. Keep the signed authorization for each consumer report, a dated copy of the written criteria you applied, the screening results, and every adverse action notice. A complete file showing identical treatment across applicants is the strongest answer to a Human Rights complaint.
On the deposit, document the lease length that sets the cap, the interest calculation when the deposit exceeds one month, the itemized statement delivered within thirty days, dated move-in and move-out records, and repair invoices that distinguish damage from normal wear.
Set one retention policy and apply it to every file, approved or denied. A consistent multi-year record of authorizations, criteria, screening results, adverse action notices, and deposit accountings gives you the evidence to answer a discrimination inquiry or a deposit dispute. Keeping the same records for everyone is itself proof of the even-handed treatment New Mexico and federal law require.
Do
- ✓Publish your written screening criteria before you advertise, and apply them to every applicant.

- ✓Handle the security deposit and its return exactly as the state statute requires, and document it.
Avoid
- ✕Charge uneven application fees, or collect a fee with no genuine screening behind it.
- ✕Treat a permissive state as a lawless one – the FCRA and federal fair housing law always apply.
- ✕Apply a blanket ban on any criminal record, which risks a disparate-impact violation.
- ✕Improvise your standards applicant by applicant instead of following one written rubric.
- ✕Skip the deposit paperwork the statute requires, from itemization to any required notices.
New Mexico Tenant Screening Laws: FAQ
Can a New Mexico landlord run a background check on an applicant?
Yes. With written authorization you may obtain a consumer report covering credit, rental history, income, and criminal convictions. The federal Fair Credit Reporting Act requires a permissible purpose and consent before any screening report is pulled.
Is there a limit on application fees in New Mexico?
No. New Mexico does not cap tenant application or screening fees. Keep the fee reasonable, tie it to the actual cost of screening, and charge it consistently to every applicant.
What is the maximum security deposit in New Mexico?
For a lease under one year, no more than one month’s rent. For a lease of one year or longer there is no fixed cap, but the deposit must be reasonable and, if it exceeds one month, the landlord must pay annual interest under NMSA 47-8-18.
When must a New Mexico landlord return the deposit?
Within thirty days after the lease ends, with an itemized list of any deductions. The landlord may not deduct for normal wear and tear.
Is source of income a protected class in New Mexico?
No. The New Mexico Human Rights Act does not list source of income, so state law does not require a landlord to accept a housing voucher. Treat every applicant by the same standard regardless.
Can a New Mexico landlord deny an applicant for a criminal record?
A conviction can be a lawful reason to decline, but blanket bans are risky. HUD’s 2016 guidance warns that a flat no-record policy can create a disparate-impact violation, so use an individualized assessment tied to the offense, how recent it is, and safety.
Does a New Mexico landlord have to send an adverse action notice?
Yes. If a denial, a higher deposit, or a co-signer requirement rests in any part on a consumer report, the FCRA requires an adverse action notice naming the reporting agency and explaining the right to a free report and to dispute it.
Does New Mexico require interest on security deposits?
Yes, when the deposit exceeds one month’s rent. NMSA 47-8-18 requires the landlord to pay the tenant annual interest at the passbook rate on the larger deposit.
How long should a New Mexico landlord keep tenant screening records?
Keep applications, signed authorizations, screening results, adverse action notices, and deposit accountings for every applicant – approved or denied – for several years. In New Mexico, a consistent retention policy is the evidence that you treated every applicant by the same standard if a fair housing or deposit dispute later arises.
When must a New Mexico landlord send the adverse action notice?
Send it promptly whenever a consumer report contributes to an adverse decision – a denial, a higher deposit, or a co-signer requirement. The FCRA notice must name the reporting agency, state that it did not make the decision, and tell the New Mexico applicant how to get a free copy of the report and dispute any error.
