Wyoming landlord rules: late fees, deposits and rent increases

Wyoming's Residential Rental Property Act says nothing on late fees, deposit size or rent increases. It is specific about when a deposit goes back. Here is what the Wyoming Statutes say, with the section for each rule.

All states

The short version

  • The statute sets no late fee cap and no required grace period. Your lease sets both.
  • There is no limit on deposit size.
  • Return the deposit within 30 days after the rental agreement ends, or 15 days after getting the renter's new mailing address, whichever is later.
  • Send a written itemization of deductions, with reasons, along with the balance. The balance goes back without interest.
  • No statute sets a notice period for raising rent, and no statewide cap appears in the statute.

Security deposits in Wyoming

Interest
None. The balance is returned without interest. Wyo. Stat. § 1-21-1208(a)

Penalty
If the owner unreasonably fails to follow the deposit rules, the renter may recover the full deposit and court costs. The statute sets no multiplier. Wyo. Stat. § 1-21-1208(c)

Rent increases in Wyoming

Notice to raise rent
No statute sets a notice period for a rent increase. No statute sets a notice period for ending a month-to-month tenancy either. Check your lease for its own notice term. Wyo. Stat. tit. 1, ch. 21, art. 12
Statewide cap
None in the statute. Wyo. Stat. tit. 1, ch. 21, art. 12
City rent control
The statutes we read don't address it. The statute neither allows nor bars local rent control. Wyo. Stat. tit. 1, ch. 21, art. 12

This page covers Wyoming state law for ordinary residential rentals. Cities and counties can add their own rules, and subsidized housing and mobile home lots follow different ones. The Wyoming Legislature's site has no per-section links for the statutes. Each citation links to the compiled PDF of Title 1, and the residential rental rules are in chapter 21, article 12.
