Wyoming Lease Amendment

This Lease Amendment is built with Wyoming as the governing state. These are the Wyoming landlord-tenant rules that most often bear on it, with the statute for each.

Security deposits in Wyoming

Wyoming places no limit on the size of a security deposit and does not require a separate account or interest. The Residential Rental Property Act focuses on disclosure and on the return process.

Nonrefundable portions — The rental agreement must state whether any portion of the deposit is nonrefundable, and the landlord must also give written notice of that fact when the deposit is taken (§1-21-1207).
Permitted deductions — Accrued rent, damage beyond reasonable wear and tear, the cost of cleaning the unit back to its move-in condition, and other costs provided for by contract (§1-21-1208(a)).
Return deadline — The balance, any prepaid rent, and a written itemization with reasons must be delivered or mailed within 30 days after termination or 15 days after the landlord receives the renter’s new mailing address, whichever is later. If the unit is damaged, the period extends by another 30 days (§1-21-1208(a)).
Renter’s address — The renter must tell the landlord, within 30 days of termination, where the refund and notice should be sent (§1-21-1208(a)).
Utility deposits — A separately identified utilities deposit must be refunded within 10 days after the renter shows all utility charges are paid; otherwise it is applied to the outstanding utility debt on a statutory timeline (§1-21-1208(b)).
Penalty — If a landlord unreasonably fails to comply, the renter may recover the full deposit plus court costs (§1-21-1208(c)).

Rent, late fees & rent increases

Wyoming has no statute governing the amount of rent, late fees, grace periods, or rent-increase notice, and no Wyoming city regulates rent. These terms are set entirely by the lease, so they need to be stated clearly.

Late fees — No statutory cap or grace period. A late fee should be written into the lease and bear a reasonable relation to the landlord’s actual costs to hold up as liquidated damages rather than an unenforceable penalty.
Rent increases — During a fixed term, rent changes only if the lease allows it. For a month-to-month arrangement, give at least the notice the lease requires to end the tenancy.
Damages & interest — A renter remains liable for damage beyond what the deposit covers, plus interest at 10% per year on unpaid amounts (§1-21-1211(b)).

Required disclosures in Wyoming

Wyoming has no state-mandated mold, radon, bedbug, flood, or landlord-identity disclosure for residential leases.

Nonrefundable deposit — The lease must state whether any part of the deposit is nonrefundable, with separate written notice at the time the deposit is paid (§1-21-1207).
Lead-based paint — Federal warning and known-hazard disclosure for housing built before 1978 (42 U.S.C. §4852d).

Tenant protections you can’t waive

Wyoming is unusual in how few protections are non-waivable: the Act lets any duty or obligation in it be assigned or modified by an explicit written agreement signed by both parties (§1-21-1202(d)). Even so, a few rules hold regardless of the lease.

Safe Homes Act — The domestic-abuse and sexual-violence protections can’t be waived or modified in any lease or side agreement, and a landlord may not end a tenancy based solely on a renter’s status as a victim (§§1-21-1303(c), 1-21-1304).
Deposit return — The §1-21-1208 return deadline and itemization rules bind whoever holds the owner’s interest when the tenancy ends, including a buyer of the property (§1-21-1209).
Court process — The Act contemplates recovering possession through a forcible entry and detainer judgment, with removal by the sheriff (§1-21-1211(a)). No Wyoming statute authorizes lockouts or utility shutoffs to force a renter out.

Wyoming Lease Amendment FAQs

How much can a landlord charge for a security deposit in Wyoming?

Wyoming sets no maximum. The lease must say whether any portion is nonrefundable, and the landlord must give written notice of that when the deposit is paid (Wyo. Stat. §1-21-1207).

How long does a landlord have to return a security deposit in Wyoming?

30 days after the lease ends or 15 days after receiving the renter’s new mailing address, whichever is later — extended by another 30 days if there is damage to the unit. The refund must include a written itemization of deductions. If the landlord unreasonably fails to comply, the renter may recover the full deposit plus court costs (§1-21-1208(c)).

Is there a limit on late fees in Wyoming?

No. Wyoming has no late-fee statute or mandatory grace period. The fee must be written into the lease and should be reasonable to be enforceable.
