LANDLORD GUIDE ยท WYOMING
Reviewed November 13, 2026
For an existing private residential tenancy. Fixed-term changes, assisted housing, mobile-home spaces and required local forms need a separate review. This guide explains selected rules; it is not a coverage determination or legal advice for a particular property.
A recommendation is not a statewide notice statute
Teton County's official lease guidance recommends at least 30 days' written notice before changing rent in a month-to-month tenancy. This guide does not present that recommendation as a Wyoming statute applying to every rental. Review the lease and applicable law before choosing the procedure.
The online tool adds a full future rent cycle to its 30-day planning floor. A longer contractual notice promise remains relevant. A fixed lease with monthly installments does not become monthly solely because of the payment schedule.
Jackson and Teton County: use the guidance for its actual purpose
The county resource helps owners and tenants understand leases, rent and fees; it does not establish a general local percentage cap. Verify any individual property's workforce-housing, affordability or other program restrictions. A restricted unit and a neighboring market-rate rental can have different rent rules.
Keep the source of any restriction in the property file, together with the agreement. If you cannot establish whether the unit is restricted, resolve that before using an ordinary private-rental amount.
Example: a conservative schedule does not amend a fixed lease
Rent is $1,800 under a lease ending June 30. Giving 45 days' notice of a proposed May increase does not by itself authorize the change during the fixed term. Review the actual clause or plan the next permitted agreement. A change to $1,890 is $90 or 5%, but permission and timing are separate from the arithmetic.
Document and communicate the final proposal
State the current total, new total and first payment date clearly. If fees or included services change too, document those obligations separately and keep the unchanged-terms statement accurate. Preserve delivery evidence and any required agreement, then make the payment system match. When a tenant disputes the proposal, review the contract before charging arrears. A rent-change letter does not decide a termination or possession dispute.
Official sources and updates
Dated caps apply only to the periods stated. Check the official sources before preparing a later increase.
