Security deposit limit

Not set by statute

Wyoming does not cap the amount of a security deposit. The residential rental property article controls how a deposit is described and returned, not how large it may be.

W.S. 1-21-1201 to 1-21-1211

  • The lease must say whether any part of the deposit is nonrefundable, and you must also give the tenant written notice of that when you take the deposit. W.S. 1-21-1207
  • A deposit held separately for utilities follows its own refund rules. W.S. 1-21-1208(b) See Returning the deposit on the Wyoming page
In the Rentari Wyoming lease

The Wyoming lease states the deposit amount and says Wyoming does not cap it.

Returning the deposit

When the rental agreement ends you may apply the deposit to accrued rent, damage beyond reasonable wear and tear, cleaning the unit to its condition at the start of the agreement, and other costs the contract provides. Deliver or mail the balance and any prepaid rent, without interest, with a written itemization of deductions and the reasons, within 30 days after termination or within 15 days after you receive the tenant's new mailing address, whichever is later.

W.S. 1-21-1208 W.S. 1-21-1209

  • If the unit is damaged, the deadline is extended by 30 days. W.S. 1-21-1208(a)
  • The tenant must tell you, within 30 days after termination, where the payment and notice may be delivered or mailed. W.S. 1-21-1208(a)
  • A deposit held and separately identified for utilities is refunded within 10 days after the tenant shows that all utility charges are paid. If the tenant makes no such showing within 45 days after termination, apply it to the tenant's utility debt within the next 15 days and pay any remainder within 7 days after that, or within 15 days after you receive the tenant's new mailing address, whichever is later. W.S. 1-21-1208(b)
  • If you unreasonably fail to follow these rules, the tenant may recover the full deposit and court costs. If you win and the court finds the tenant sued unreasonably, you may be awarded court costs. W.S. 1-21-1208(c)
  • Whoever holds the owner's interest when the agreement ends is bound by the deposit rules, so a buyer takes on the duty to return existing deposits. W.S. 1-21-1209
  • If the tenant's damage costs more than the deposit, the tenant stays liable for the rest, plus interest at 10 percent a year on unpaid amounts. W.S. 1-21-1211(b)
In the Rentari Wyoming lease

The lease repeats the 30-day and 15-day deadlines, the 30-day extension for damage, the tenant's duty to give an address, the 10-day utilities refund and the full-deposit penalty.

Deposit account and interest

Wyoming does not require you to pay interest on a deposit: the balance is returned without interest. No section of the residential rental property article requires a separate or trust account for deposits.

W.S. 1-21-1208(a) W.S. 1-21-1201 to 1-21-1211

  • A utilities deposit must be separately identified to get its own refund timeline. W.S. 1-21-1208(b) See Returning the deposit on the Wyoming page
In the Rentari Wyoming lease

The lease says the balance and prepaid rent are returned without interest.

Move-in condition

Not set by statute

No section of Wyoming's residential rental property article requires a move-in checklist, inspection report or photographs. The condition at the start of the agreement still matters: the tenant must leave the unit clean to that condition, and you may deduct the cost of cleaning to it.

W.S. 1-21-1201 to 1-21-1211

  • At the end of the agreement the tenant must remove all property and garbage and clean the unit to its condition at the beginning of the agreement. W.S. 1-21-1204(a)(viii)
  • Deductions may cover cleaning to the starting condition and damage beyond reasonable wear and tear. W.S. 1-21-1208(a) See Returning the deposit on the Wyoming page
In the Rentari Wyoming lease

The lease has the tenant accept the home as documented in any move-in condition report and report pre-existing damage in writing within seven days of move-in.

Questions

Is there a limit on security deposits in Wyoming?

No. Wyoming sets no maximum. It does control the return: send the balance with a written itemization within 30 days after the agreement ends or 15 days after you receive the tenant's new mailing address, whichever is later.

W.S. 1-21-1201 to 1-21-1211 W.S. 1-21-1208(a)

Can part of a Wyoming deposit be nonrefundable?

Only if the rental agreement says so. Any rental agreement must state whether any portion of a deposit is nonrefundable, and you must give the tenant written notice of that when you take the deposit.

W.S. 1-21-1207

What happens if I do not return the deposit on time?

If you unreasonably fail to follow the deposit rules, the tenant may recover the full deposit and court costs. If the tenant sues unreasonably and you win, the court may award you court costs.

W.S. 1-21-1208(c)
