Wyoming landlord-tenant law.

Security deposits

Deposit limit. No statutory cap on the amount of a security deposit. If any part of the deposit is designated nonrefundable, the landlord must say so in writing at the time the deposit is taken (W.S. § 1-21-1207).

Getting it back. Landlord must deliver or mail the balance plus a written itemized list of deductions within 30 days after the rental agreement ends, or 15 days after receiving the tenant's new mailing address, whichever is later, extended by another 30 days if the unit was damaged, a separately held utility deposit follows its own 10-day and 45-day timeline (W.S. § 1-21-1208(a), (b)).

Late fees and rent

Wyoming's landlord-tenant statute does not set a late fee cap or a mandatory grace period, so late fees are governed entirely by the lease terms.

Ending a tenancy

Nonpayment of rent. Nonpayment allows a forcible entry and detainer action after rent is unpaid for 3 days past due, and the landlord must still serve a written notice to quit at least 3 days before filing suit, in practice a 3-day notice (W.S. §§ 1-21-1002(a)(i), 1-21-1003).

Month-to-month termination. Wyoming has no specific statute setting a numeric notice period for ending a month-to-month tenancy, practice generally follows the common-law rule of notice equal to one rental period (commonly treated as 30 days), this is not codified in a single Wyoming statute so treat it as unsettled and confirm locally before relying on it.

Landlord entry

Wyoming has no statute requiring landlords to give advance notice before entering a unit, W.S. § 1-21-1205(a)(iii) only bars a tenant from unreasonably refusing entry for repairs, inspection, or showings, it does not create a landlord notice duty.

Required disclosures

• Federal lead-based paint disclosure and pamphlet for units built before 1978 (42 U.S.C. § 4852d)
• Written notice at the time the deposit is taken if any part of it is nonrefundable (W.S. § 1-21-1207)

Lease clauses that do not hold up

• Any lease clause waiving or modifying the Wyoming Safe Homes Act protections for domestic abuse or sexual violence victims is void (W.S. § 1-21-1304)
• Terminating a tenancy solely because a tenant, applicant, or household member is a victim of domestic abuse or sexual violence (W.S. § 1-21-1303(c))

Notes for landlords

Wyoming has one of the thinnest statutory landlord-tenant frameworks in the country, so most terms such as late fees, notice-to-enter, and month-to-month notice are left to the lease and general contract law rather than a specific statute. The one area with real teeth is the Safe Homes Act, which cannot be waived and lets a domestic violence victim break a lease with 7 days notice and supporting evidence.
