Wyoming's security-deposit statute is short, and it reflects the state's broadly landlord-favorable posture. There is no cap on how much a landlord can collect, no requirement to hold the deposit in a separate or interest-bearing account, and no double- or triple-damages penalty of the kind many states impose for a wrongful withholding. What Wyoming does require is specific and worth getting right: a written disclosure if any part of the deposit is nonrefundable, and the return of the balance, with an itemized statement, on a distinctive two-part clock, within 30 days of termination or 15 days after the tenant gives a new mailing address, whichever is later. Miss that deadline unreasonably, and the tenant can recover the full deposit and court costs.

For a property manager, the practical takeaway is that Wyoming is easy to comply with but also easy to get wrong on timing, because the return clock is not a simple 30 days: it depends on when (and whether) the tenant provides a forwarding address, and it extends when there is damage to assess. This guide walks the actual statute, Wyo. Stat. §§ 1-21-1207 and 1-21-1208, on the cap (or lack of one), the disclosure rule, permitted deductions, the return deadline, the utilities-deposit rules, and the penalty, and the operational habits that keep a Wyoming deposit return clean.

Key Points

• No cap: Wyoming sets no statutory maximum on the security deposit amount.

• Nonrefundable disclosure (§ 1-21-1207): if any portion of the deposit is nonrefundable, the rental agreement must say so, and the landlord must give the tenant written notice of that fact when the deposit is collected.

• Return deadline (§ 1-21-1208(a)): the balance plus a written itemization must be delivered or mailed, without interest, within 30 days of termination or 15 days after the landlord receives the tenant's new mailing address, whichever is later, extended by another 30 days if there is damage to the unit.

• Tenant's duty: the tenant must, within 30 days of termination, tell the landlord where payment and notice can be sent.

• Permitted deductions: accrued rent, damage beyond reasonable wear and tear, the cost to clean the unit to its move-in condition, and other costs the lease provides for.

• Penalty (§ 1-21-1208(c)): for an unreasonable failure to comply, the tenant may recover the full deposit and court costs, there is no damages multiplier, and the landlord can recover court costs if the tenant sued unreasonably.

• Utilities deposit: a separately identified utilities deposit has its own refund timeline (§ 1-21-1208(b)).

No Statutory Cap on the Deposit

The first distinctive feature is what Wyoming does not do: it sets no statutory limit on the amount of a security deposit. Unlike states that cap the deposit at one or two months' rent, Wyoming does not impose a statutory cap on the amount, leaving it to the rental agreement and applicable general contract-law limits. A landlord can require whatever deposit the market will bear, and there is no per-statute ceiling. (As a practical matter, a court could in principle treat a wildly excessive deposit as unconscionable, but there is no bright-line statutory cap.)

Two related "no requirement" points round out the picture. Wyoming does not require the landlord to hold the deposit in a separate account, an escrow account, or an interest-bearing account, and the statute expressly provides that the deposit is returned without interest. And Wyoming does not require the landlord to disclose where the deposit is held. In short, on the front end, the deposit is lightly regulated: set the amount by agreement, without a statutory deposit cap, and return it without interest. The regulation is almost entirely on the back end, at return.

The One Front-End Rule: Nonrefundable Disclosure

There is one thing Wyoming does require when the deposit is collected. Under Wyo. Stat. § 1-21-1207, if any portion of the security deposit is nonrefundable, two things must happen: the rental agreement must state that a portion is nonrefundable, and the landlord (or the landlord's agent) must give the tenant written notice of that fact at the time the deposit is collected. Absent both, a landlord who later tries to keep a "nonrefundable" portion is on weak ground, because the statute conditions a nonrefundable deposit on that upfront written disclosure.

For a manager, this is a small but easy-to-miss compliance step: if the lease contemplates any nonrefundable deposit (for example, a nonrefundable cleaning or pet portion), it must be spelled out in the lease and separately disclosed in writing when the money changes hands. A nonrefundable portion that is not properly disclosed may be difficult for the landlord to enforce as nonrefundable and may be subject to the ordinary deposit-return requirements.

Permitted Deductions and the Return Clock

The heart of the statute is Wyo. Stat. § 1-21-1208, which governs deductions, the itemization, and the timing.

Permitted deductions. Upon termination, the landlord may apply the deposit to: accrued (unpaid) rent; damage to the unit beyond reasonable wear and tear; the cost to clean the unit to the condition it was in at the beginning of the tenancy; and any other costs provided for in the lease. The wear-and-tear line is the usual dividing line, ordinary deterioration from living in the unit is not deductible; damage beyond that is.

The return deadline. This is the provision the title highlights, and it is a two-part, "whichever is later" clock. The landlord must deliver or mail the balance of the deposit (and any prepaid rent), together with a written itemization of any deductions and the reasons for them, without interest, within 30 days after termination of the rental agreement or within 15 days after the landlord receives the tenant's new mailing address, whichever is later. And there is an extension: if there is damage to the unit, the period is extended by an additional 30 days to allow the landlord to assess and document it.

The "whichever is later" structure matters because the applicable deadline depends on both the termination date and the date the landlord receives the tenant's new mailing address. If no new mailing address is received, the 30-day period after termination remains the operative deadline. If the landlord receives the address later, the 15-day period is compared with the 30-day period, and the later date controls. If there is damage to the unit, the applicable period is extended by an additional 30 days. So the real deadline in a given case is not simply "30 days"; it is the later of those dates, plus 30 more if there is damage.

The tenant's address duty. The statute puts a corresponding obligation on the tenant: the renter must, within 30 days of termination, notify the landlord of the location where payment and notice may be sent. This is why documenting the move-out and requesting a forwarding address is a two-way street, and why a manager should always record the date any forwarding address is received (it can start or move the 15-day clock).

The Penalty: Full Deposit and Court Costs, No Multiplier

Here is where Wyoming diverges sharply from tenant-protective states, and where a widely-repeated error creeps into secondary guides. Wyoming's deposit statute does not impose a double- or triple-damages penalty. Under § 1-21-1208(c), if the landlord unreasonably fails to comply with the return or utilities-refund requirements, the tenant may recover the full deposit and court costs, and that is the extent of the statutory remedy. There is no damages multiplier, no automatic penalty beyond the deposit and costs. (Any guide stating Wyoming imposes "double damages" on a wrongful withholding is misreading the statute.)

Two further features underscore how landlord-favorable this is. First, the trigger is an unreasonable failure, not any late return; a landlord who is late for a defensible reason is in a different position than one who simply ignores the obligation. Second, the statute is two-sided on costs: if the tenant sues, the landlord prevails, and the court finds the tenant acted unreasonably in bringing the action, the landlord may recover court costs. That reciprocal cost provision is unusual and discourages meritless deposit suits. None of this makes the return optional, an unreasonable failure still costs the landlord the full deposit plus the tenant's costs, but it is a far lighter penalty regime than the multiplier statutes common elsewhere. For contrast, a strongly tenant-protective regime like the one in RIOO's guide to Rhode Island security deposit laws pairs a one-month cap and a 20-day return with double damages for a wrongful withholding, exactly the kind of cap-plus-multiplier structure Wyoming does not have.

The Utilities Deposit

Wyoming treats a separately identified utilities deposit on its own timeline under § 1-21-1208(b), which a manager handling utilities deposits should know. Such a deposit must be refunded within 10 days of the tenant's satisfactory showing that all utility charges the tenant incurred have been paid. If the tenant does not make that showing within 45 days of termination, the landlord must, within 15 days after that, apply the utilities deposit to the outstanding utility debt. Any refund then due the tenant is paid within 7 days after the deposit is applied to the debt (or within 15 days after the landlord receives the tenant's new mailing address, whichever is later). The point for a manager is that a utilities deposit is not on the same 30/15-day clock as the general deposit; it has its own, showing-driven schedule.

Where Wyoming Landlords Create Preventable Risk

Because the front end is lightly regulated but the back-end timing is specific, most avoidable Wyoming deposit problems are timing or documentation failures.

Treating the deadline as a flat 30 days. The deadline is the later of 30 days after termination or 15 days after receiving the tenant's new mailing address, extended by 30 more if there is damage. Miscounting, especially ignoring the address prong, is the most common error.

Not documenting the forwarding-address date. Because the 15-day prong runs from receipt of the tenant's new address, the date that address arrives can control the deadline. Record it.

Charging a "nonrefundable" deposit without the § 1-21-1207 disclosure. A nonrefundable portion requires both a lease statement and written notice when the deposit is collected; skip either and the portion may be hard to enforce as nonrefundable.

Returning the deposit without a written itemization. The statute requires the balance to be accompanied by a written itemization of deductions and the reasons; a bare partial refund invites a dispute.

Deducting for ordinary wear and tear. Only damage beyond reasonable wear and tear, unpaid rent, cleaning to move-in condition, and lease-specified costs are deductible.

Mishandling a utilities deposit on the wrong clock. A separately identified utilities deposit runs on the § 1-21-1208(b) showing-based schedule, not the general 30/15-day clock.

Because the return, the itemization, and the timing are the parts of Wyoming's deposit law with real deadlines, keeping the move-out inspection, the itemized deductions, and the forwarding-address date organized is what keeps a Wyoming deposit return clean. Running the move-out and deposit reconciliation through a structured move-in and move-out process is what produces the documented, itemized accounting the statute requires and captures the address date that can control the deadline.

Key Takeaways for Wyoming Landlords

• Wyoming sets no statutory cap on the security deposit and requires no separate account, no interest, and no disclosure of where the deposit is held

• If any portion of the deposit is nonrefundable, the lease must say so and the landlord must give written notice when the deposit is collected (§ 1-21-1207)

• The balance plus a written itemization must be returned, without interest, within the later of 30 days after termination or 15 days after receiving the tenant's new mailing address, extended by 30 days if there is damage (§ 1-21-1208(a))

• Permitted deductions are accrued rent, damage beyond reasonable wear and tear, cleaning to move-in condition, and other lease-specified costs

• The tenant must, within 30 days of termination, tell the landlord where payment and notice can be sent

• The penalty for an unreasonable failure to comply is the full deposit and court costs, with no damages multiplier, and the landlord can recover court costs if the tenant sued unreasonably (§ 1-21-1208(c))

• A separately identified utilities deposit runs on its own showing-based schedule (§ 1-21-1208(b))

The Landlord-Favorable Deposit Regime in Context

Wyoming's deposit statute fits the state's broader landlord-favorable framework: a thin set of rules, a great deal left to the lease, and penalties that are real but modest compared with tenant-protective states. The absence of a cap, an interest requirement, and a damages multiplier all point the same direction. But the flip side is that the few rules Wyoming does impose, the nonrefundable disclosure and the two-part return clock with its itemization requirement, are specific and enforceable, and an unreasonable failure to return on time still costs the landlord the full deposit and the tenant's court costs. The operators who handle Wyoming deposits cleanly are the ones who treat the return deadline as the two-part clock it actually is, always capture the forwarding-address date, itemize every deduction in writing, and disclose any nonrefundable portion up front. In a state that regulates the deposit lightly, getting the handful of real requirements right is the whole job. For the wider Wyoming picture, RIOO's guide to the Cheyenne and Jackson Hole rental markets covers how the state's minimal framework plays out in its two very different local markets.

Frequently Asked Questions

1. Is there a limit on security deposits in Wyoming?

No. Wyoming sets no statutory cap on the amount of a security deposit; the amount is set by the lease and the market. Wyoming's deposit statute also does not require the deposit to be held in a separate or interest-bearing account, does not require interest to be paid (the statute returns it "without interest"), and does not require the landlord to disclose where the deposit is held.

2. How long does a Wyoming landlord have to return a security deposit?

Under Wyo. Stat. § 1-21-1208(a), the landlord must deliver or mail the balance of the deposit, with a written itemization of any deductions, within the later of 30 days after the rental agreement terminates or 15 days after the landlord receives the tenant's new mailing address. If there is damage to the unit, the period is extended by an additional 30 days. The deposit is returned without interest.

3. What can a Wyoming landlord deduct from a security deposit?

Under § 1-21-1208(a), the landlord may deduct for accrued (unpaid) rent, damage to the unit beyond reasonable wear and tear, the cost to clean the unit to the condition it was in at the start of the tenancy, and any other costs provided for in the lease. Ordinary wear and tear cannot be deducted, and the deductions must be itemized in writing with the reasons.

4. What is the penalty if a Wyoming landlord doesn't return the deposit?

Under § 1-21-1208(c), if the landlord unreasonably fails to comply with the return requirements, the tenant may recover the full deposit and court costs. Wyoming does not impose a double- or triple-damages multiplier, so guides stating otherwise are incorrect. If the tenant sues, the landlord prevails, and the court finds the tenant acted unreasonably in bringing the action, the landlord may recover court costs.

5. Does the tenant have to do anything to get the deposit back?

Yes. Under § 1-21-1208(a), the tenant must, within 30 days of termination, notify the landlord of the location where payment and notice may be sent, that is, provide a forwarding address. That address also matters for timing, because the 15-day prong of the return deadline runs from the date the landlord receives it.

6. Can a Wyoming landlord charge a nonrefundable deposit?

Yes, but only with proper disclosure. Under § 1-21-1207, if any portion of the deposit is nonrefundable, the rental agreement must state that fact and the landlord must give the tenant written notice of it at the time the deposit is collected. A nonrefundable portion that is not properly disclosed this way may be difficult to enforce as nonrefundable and may be subject to the ordinary deposit-return requirements.
