Quick AnswerA Wyoming residential lease is governed by Wyo. Stat. Title 1, Ch. 21. There is no deposit cap, but the deposit must be returned with a written itemization within 30 days of termination (or 15 days after the tenant's forwarding address, whichever is later), plus an extra 30 days if there is damage (§ 1-21-1208). Any nonrefundable portion must be disclosed in writing (§ 1-21-1207). Wyoming has no late-fee cap and no statutory month-to-month notice period (the lease governs). Nonpayment takes a 3-day notice to quit (§ 1-21-1002/1003). A 2021 law added an implied warranty of habitability (§ 1-21-1202).
Wyoming has a light statutory framework, but a 2021 habitability law and a nonrefundable-fee disclosure rule are worth getting right. This guide walks through every clause, figure, and notice a Wyoming landlord should build into a compliant 2026 lease. For the national baseline, see What Every Residential Lease Agreement Must Include.

What clauses are legally required in every Wyoming lease agreement?

Every Wyoming lease should identify the landlord/agent and all adult tenants, the property, the rent and due date, and the term. Wyoming requires a written disclosure of any nonrefundable portion of the deposit (§ 1-21-1207), and since 2021 an implied warranty of habitability applies (§ 1-21-1202). Because there is no statutory notice period to end a periodic tenancy, the lease should state one explicitly.

Wyoming security deposit rules — the 30-day return

Wyo. Stat. §§ 1-21-1207 to 1-21-1208 govern deposits:

  • No cap on the deposit amount.
  • Nonrefundable portions: any nonrefundable deposit must be disclosed in writing when the deposit is taken (§ 1-21-1207).
  • Return: within 30 days after termination, or 15 days after the landlord receives the tenant's forwarding address, whichever is later; if there is damage, the period is extended by an additional 30 days (up to 60 total). A written itemization of deductions is required.
  • Penalty: a landlord who fails to comply must return the full deposit and pay the tenant's court costs (§ 1-21-1208).

Late fees and rent rules in Wyoming

Wyoming does not set a statutory cap on residential late fees and has no rent control. A late fee is enforceable if it is written into the lease and reasonable.

Notice periods to end or not renew a Wyoming lease

Wyoming notice periods:

SituationNoticeStatute
Terminate a periodic (month-to-month) tenancyNo statutory period — the lease governs (30 days is common practice)
Nonpayment of rent3-day written notice to quit before filing§ 1-21-1002/1003

Because Wyoming has no statute mandating notice to end a periodic tenancy, the lease should specify the notice period. Nonpayment uses a 3-day notice to quit before a forcible-entry-and-detainer action. Self-help eviction is unlawful.

What disclosures must Wyoming landlords provide?

Wyoming's required disclosures:

  • Nonrefundable deposit (§ 1-21-1207): written disclosure of whether any portion of the deposit is nonrefundable, given when the deposit is taken.
  • Lead-based paint (federal): the disclosure and EPA pamphlet for pre-1978 housing.

Since 2021, § 1-21-1202 also imposes an implied duty to keep the unit in a safe and sanitary condition fit for human habitation — operational electrical, heating, plumbing, and hot and cold running water — with a tenant notice-and-cure process.

What happens if a Wyoming lease is missing required terms?

Specific failures carry specific consequences:

  • Missed 30-day return / no itemization: the landlord must return the full deposit plus the tenant's court costs (§ 1-21-1208).
  • Undisclosed nonrefundable fee: a fee not disclosed in writing as nonrefundable is treated as refundable (§ 1-21-1207).
  • Habitability failure: the tenant may use the notice-and-cure process and pursue remedies under § 1-21-1202.

Full Wyoming disclosure checklist

For a dedicated, statute-by-statute rundown of every notice a Wyoming landlord must give at signing, see our Wyoming required lease disclosures checklist.

A compliant Wyoming lease pairs the universal essentials with the state's specifics: no deposit cap but a 30-day itemized return, the nonrefundable-fee disclosure, a 3-day nonpayment notice, and the 2021 implied warranty of habitability — plus an explicit lease-stated notice period since the statute provides none. LeaseHelper generates a Wyoming-specific lease pre-populated with these clauses so nothing required is left out.
