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:
| Situation | Notice | Statute |
|---|---|---|
| Terminate a periodic (month-to-month) tenancy | No statutory period — the lease governs (30 days is common practice) | — |
| Nonpayment of rent | 3-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.
