Wyoming’s security deposit law is straightforward: no statutory cap, and a deadline that is the later of 30 days after the tenancy ends and 15 days after the landlord receives your new mailing address. Where there is damage to the unit, the period stretches by another 30 days. An owner who unreasonably fails to comply owes the full deposit plus court costs. Wyoming’s framework gives landlords flexibility while holding them accountable for timely, itemized retuctions are made.

The Short Answer

Wyoming imposes no statutory cap on security deposits, allowing landlords and tenants to negotiate freely. Deposits must return within 30 days of the rental agreement terminating or 15 days after the owner receives your new mailing address, whichever is later, with an itemized written list of deductions and the reasons for them. If there is damage to the unit, add 30 days. An unreasonable failure to comply exposes the owner to a claim for the full deposit plus court costs in small claims court.

Security Deposit Cap

Wyoming has no statutory cap on security deposits. Landlords and tenants can agree to any deposit amount through their lease terms—from one month’s rent to several months or more, depending on negotiation and circumstances. However, market practice in Wyoming typically keeps deposits between one and two months’ rent.

The 30-Day Return Deadline (and the 15-Day Address Rule)

Wyoming offers a dual-timeline system:

The base rule: 30 days after the rental agreement terminates
The address arm: or 15 days after the owner receives your new mailing address, whichever is later. You must give that address within 30 days of termination. If there is damage to the unit, the whole period is extended by another 30 days

This incentivizes landlords to process deposits quickly and cleanly. The return must include an itemized written list of any deductions. A handwritten or typed list is acceptable, but it must itemize each deduction separately by category.

What Can a Wyoming Landlord Legally Deduct?

Landlords may deduct for:

Unpaid rent or utilities
Damage beyond normal wear and tear
Reasonable cleaning costs (documented)
Repair or replacement of tenant-damaged property
Lease violation charges (pet fees, etc., if lease permits)
Any other damages specified in the lease

Deductions should be documented with receipts, repair estimates, or cleaning invoices when available.

What Is Normal Wear and Tear in Wyoming?

Normal wear and tear includes:

Light fading or scuffing of paint from normal living
Minor wall marks from furniture or pictures
Worn carpet pile or small stains from regular use
Small dents in drywall that don’t expose framing
Worn cabinet or door hardware from daily use
Faded window coverings from sunlight
Minor settling cracks in drywall
Dust or slight discoloration on fixtures from age
Light wear on door hinges or light switches

Beyond normal wear and tear (deductible):

Holes in walls or doors
Permanent carpet stains, burns, or odors
Non-functional or broken appliances
Pet damage including urine stains, scratching, or other damage
Broken windows, locks, doors, or hardware
Damage to tile, flooring, or major fixtures
Graffiti, intentional marks, or vandalism
Accumulation of dirt, trash, or pest evidence
Damage from negligence or carelessness

Penalties for Wrongful Withholding

If a Wyoming landlord wrongfully withholds a deposit, the tenant can sue and recover:

The full deposit, not merely the amount wrongly kept (§ 1-21-1208(c))
Court costs associated with the claim

Wyoming provides no multiplier and no attorney’s fees, and the remedy has a condition: § 1-21-1208(c) reaches only an owner who unreasonably fails to comply. When it applies, though, the renter recovers the whole deposit, which is often more than the amount in dispute. The section cuts both ways: if the owner wins and the court finds you sued unreasonably, it may award the owner court costs.

How to Get Your Deposit Back in Wyoming

Provide a forwarding address in writing when you vacate. Email or written notice both work; keep a copy for your records.
Document the unit’s condition with time-stamped photos and video at move-in and move-out, showing all rooms and damage.
Perform a thorough move-out cleaning to minimize legitimate cleaning deductions.
Request a move-out inspection with the landlord in writing, allowing both parties to assess condition together.
Keep copies of all lease documents and payment records to refute unpaid rent claims.
Mark your calendar for the correct deadline:
- 15 days after the owner receives your new mailing address, if that is later
- 30 days from termination of the rental agreement, plus another 30 if there is damage
Expect the itemized list within the applicable deadline. Wyoming law requires itemization, so vague or undocumented deductions are questionable.
Review deductions for reasonableness and documentation. If a repair is listed without a receipt or invoice, challenge it.
Respond in writing if the deposit is not returned on time or if deductions seem excessive. Request immediate return or specify your intent to pursue small claims.
File in small claims court if the deadline passes or deductions are clearly wrongful. Bring your lease, move-out photos, communication records, and any itemized statement provided.

Key Statute

Wyoming Statutes § 1-21-1208 – the return deadline and its 15-day address arm, the 30-day extension where there is damage, the separate utilities-deposit schedule, and the full-deposit remedy for an unreasonable failure to comply.

Real Situations in Wyoming

In Cheyenne, a tenant rented an apartment for two years with a $1,500 security deposit and moved out. The tenant gave a new mailing address on move-out day, and the landlord returned the deposit on day 18 with an itemized statement confirming “no deductions claimed.” Both arms of § 1-21-1208(a) were satisfied: inside 30 days of termination and well past nothing. This straightforward return prevented disputes and reflected landlord compliance.

In Casper, a landlord returned a deposit on day 32 (two days late) with an itemized statement claiming $400 for carpet cleaning and $300 for paint. The statement provided a receipt for the cleaning service but no proof that the painting work was performed. The tenant objected to the painting deduction in writing, demanding documentation. The landlord provided no response. The tenant sued in small claims court for the $300 in wrongfully withheld amount plus court costs, recovering approximately $350 total.

In Laramie, a tenant provided a forwarding address on move-out day. The landlord returned the full deposit on day 14 with a detailed itemization that included $250 for carpet cleaning with a supporting invoice and $150 for minor paint touch-ups with a contractor estimate. Both deductions were documented and inside the 30-day deadline. The tenant reviewed the charges, found them reasonable, and accepted the return. This compliant, transparent return prevented any dispute.

Common Mistakes Wyoming Tenants Make

Believing in a 15-day no-deductions deadline. There is no such rule. The 15 days in § 1-21-1208(a) run from the owner’s receipt of your new mailing address, and only as the later of the two arms. What you should do is give that address in writing within 30 days of termination, as the statute requires, and keep proof of when it arrelerated deadline. Reference the 15-day timeline in your communications to set clear expectations.

Accepting itemized statements with deductions but no supporting documentation without demanding proof immediately. If the itemized statement lists repairs or cleaning costs without invoices or receipts, respond within 7 days with a certified letter demanding documentation. Wyoming law requires itemization but does not mandate receipts be attached to the initial statement. However, landlords should provide them upon request within a reasonable time.

Underestimating the remedy. § 1-21-1208(c) does not limit you to the amount wrongly kept: an owner who unreasonably fails to comply owes the full deposit plus court costs. Remember the condition, though — unreasonable failure, not a few days’ slippage — and that an unreasonable lawsuit can cost you the owner’s costs. Document the late return and demand payment within 10 days before filing in small claims court.
