💵 New Mexico Security Deposit Laws

New Mexico security deposit law is governed primarily by NMSA § 47-8-18. The framework regulates how much can be collected (1 month (unfurnished, lease under 1yr)), how long the landlord has to return it (30 days), what can be deducted, and the penalties for wrongful withholding (Damages + attorney fees).

This guide covers the full New Mexico security deposit framework — allowable deposit amounts (1 month (unfurnished, lease under 1yr)), holding requirements, allowable deductions, normal wear and tear, the 30 days return deadline, itemization (Yes), interest requirements (Yes (over 1 month)), penalties, and practical compliance strategy. Written for New Mexico landlords and tenants, every section ties to a concrete compliance action.

Understanding New Mexico’s security deposit framework is essential for every New Mexico landlord — the penalties for getting it wrong can be substantial. New Mexico’s specific rules: deposit cap 1 month (unfurnished, lease under 1yr), return deadline 30 days, penalty for wrongful withholding damages + attorney fees. The landlords who routinely comply with NMSA § 47-8-18 never face these penalties; the landlords who don’t face them on every move-out dispute.

New Mexico deposit law under NMSA § 47-8-18 establishes a precise sequence that landlords must follow. Every step has a role — miss one and the deposit must be returned in full regardless of the condition of the property. Understand the sequence and compliance becomes a checklist, not a judgment call.

1. Tenant Surrenders the PremisesThe 30 days clock does not start when the lease ends — it starts when the tenant actually surrenders. Surrender means returning keys, removing belongings, and ending occupancy. Keep dated documentation of the surrender event.
2. Tenant Provides Written Forwarding AddressIn New Mexico, the written forwarding address is typically treated as a condition precedent to the landlord’s return obligation. Until the address is received, the landlord has no obligation to return the deposit. This is a critical protection for landlords.
3. Landlord Inspects and DocumentsConduct the move-out inspection promptly after surrender. Photograph every room, every floor, every fixture. Compare against the move-in inspection report. Written documentation survives court; memory doesn’t.
4. Landlord Calculates DeductionsDeductions can only cover unpaid rent, damages beyond normal wear and tear, unpaid utilities, and lease-specified charges. Every deduction requires a specific invoice, estimate, or documented cost basis.
5. Landlord Returns Balance with Itemized StatementWithin 30 days of steps 1 and 2, the landlord must deliver the remaining deposit balance along with a written itemized statement of all deductions. Failure to itemize forfeits the right to withhold any portion.

New Mexico deposit law defines deductible categories narrowly. The landlord bears the burden of proving each deduction is legitimate. The list is shorter than most landlords assume — and what’s not on the list defaults to “normal wear and tear” that must be absorbed by the landlord.

✅ Properly Deductible

• Unpaid rent owed for the final month or any prior periods
• Physical damage beyond normal wear and tear — holes in walls, broken fixtures, missing items
• Unpaid utilities that the landlord had to cover
• Professional cleaning beyond routine turnover (smoke damage, pet contamination, unusual filth)
• Damage from unauthorized alterations — painting without permission, installed fixtures left behind
• Late fees specified in the lease that remain unpaid
• Lease-specified charges (key fees, specific cleaning charges)

❌ Not Deductible — Normal Wear and Tear

• Routine paint touch-ups for minor scuffs and marks
• Carpet cleaning for ordinary soiling (no stains, pet damage, or unusual odors)
• Minor nail holes from hanging pictures
• Faded paint, carpets, or fixtures from age and use
• Worn but functional appliances
• Caulk degradation around tubs and sinks from ordinary use
• Regular maintenance issues the landlord failed to address during tenancy

⚠️ Disputed Territory

• Extensive cleaning costs — landlord must show beyond turnover cleaning
• Paint for smoker-stained walls — defensible if unusual; not if light
• Full carpet replacement for localized damage — must prorate by age
• Landscaping for ordinary dead grass — usually not deductible

New Mexico tenants have specific, enforceable rights under NMSA § 47-8-18. These aren’t abstract — they translate directly into small claims recoveries when landlords violate the rules. The burden of proof is on the landlord, and the penalties can be material.

1. Right to Prompt Return30 days is a hard deadline in New Mexico once the tenant has vacated and provided a written forwarding address. Missing the deadline typically triggers the presumption of bad faith.
2. Right to ItemizationAny deduction requires a written itemized statement. The landlord must describe the damage or charge and specify the amount. “Cleaning — $400” is not itemization; “Professional pet-odor remediation (invoice attached): $400” is.
3. Right to Challenge DeductionsTenants can dispute every deduction. The landlord carries the burden of proving each charge was for damage beyond normal wear and tear.
4. Right to Sue in Small ClaimsSmall claims courts in New Mexico handle deposit disputes without requiring an attorney. The process is designed to be accessible without an attorney.
5. Right to Statutory DamagesWhere bad faith is proven or presumed, the tenant recovers statutory damages under NMSA § 47-8-18: Damages + attorney fees. These remedies are typically mandatory, not discretionary.

Penalty Math — What Wrongful Withholding Actually Costs

Deposit amounts and handling vary across New Mexico’s rental markets. NMSA § 47-8-18 applies uniformly statewide, but local rental market conventions shape what’s typical. Knowing the going rate for your market keeps deposits reasonable and tenant-friendly.

New Mexico landlords who follow this playbook virtually never face deposit-return penalties. The list is short, but every item compounds to create a portfolio-wide safety net.

📋 Move-In Documentation

• Photograph every room, floor, wall, and fixture in detail
• Complete written move-in inspection form signed by tenant
• Store documentation both digitally and physically
• Note any pre-existing damage or wear explicitly
• Have tenant acknowledge the inspection in writing

💰 Deposit Collection & Holding

• Collect deposit separately from first month rent with documentation
• Provide written receipt specifying “security deposit”
• Hold deposit in a separate account if possible (best practice, not required)
• Track deposits per unit with tenant name and lease dates
• Maintain records for the full tenancy plus applicable statute of limitations

🚪 Move-Out Procedures

• Request written forwarding address in writing at or before move-out
• Conduct move-out inspection within 3 days of surrender
• Photograph everything again for comparison to move-in
• Gather invoices, estimates, and documentation for all charges
• Calendar the 30 days return deadline as a hard deadline, not a target
• Mail balance + itemized statement by certified mail with return receipt
