The most expensive mistake a Wyoming landlord makes isn't botching an eviction. It's the word "nonrefundable." Call a cleaning fee nonrefundable without stating that in the rental agreement and in a separate written notice when you take the money, and Wyo. Stat. § 1-21-1207 quietly makes it refundable. Pair that with the deposit statute's other trap, an itemization deadline that forfeits the entire deposit plus court costs if you unreasonably blow it, and the state's loosest-in-the-nation reputation starts to look overstated.

Wyoming really is a freedom-of-contract state: no rent control, no late fee statute, no entry-notice minimum, 3-day eviction notices. But the handful of rules it does have carry forfeiture-grade penalties, so they're worth knowing cold. The quick numbers are on the Wyoming quick-reference page; here's the full picture.

Security deposits: no cap, a two-part clock, and a forfeiture rule

There's no limit on what you can collect. The regulation is all on the way out. Under Wyo. Stat. § 1-21-1208, you must deliver or mail the deposit balance, without interest, plus a written itemization of every deduction and the reason for it, within 30 days after the rental agreement ends or within 15 days after you receive the renter's new mailing address, whichever is later.

Read that twice: it's whichever is later, not sooner. A tenant who sends a forwarding address three weeks after move-out restarts your window. If the unit was damaged beyond normal wear and tear, the statute gives you 30 additional days, and a separate utilities deposit must be refunded within 10 days once the utility bills are squared.

You may deduct accrued rent, damage beyond reasonable wear and tear, the cost of cleaning the unit back to its move-in condition, and other costs the contract provides for. But if you unreasonably fail to return the balance or send the itemization on time, the renter can recover the full deposit and court costs, including money that would have covered genuine damage. Wyoming judges don't have to split the difference; the statute hands the whole thing back.

Neighbors run tighter clocks: Arizona gives 14 business days, Idaho 21 days unless the lease extends it to 30, and Colorado 30 days with a lease option for 60. Wyoming's clock is friendlier, right up until the forfeiture rule makes it the harshest of the four. Rentari tracks each state's deposit deadline automatically, which is cheap insurance against a statute this unforgiving.

Ending tenancies and getting inside: the code trusts your lease

Wyoming has no statute setting the notice to end a month-to-month tenancy. None. The 30-day figure everyone quotes is common law custom and standard lease language, not a code section. That cuts in your favor only if your lease actually says 30 days (or whatever period you want); a silent agreement leaves both sides arguing about "reasonable notice" in circuit court. Write it down, and use written notice when you terminate, dated and delivered in a way you can prove. Solid templates live in the forms library.

Entry works the same way, with one twist most landlords miss. No statute makes you give 24 or 48 hours' notice. Instead, the code puts the duty on the renter: under Wyo. Stat. § 1-21-1205, a renter may not "unreasonably deny access to, refuse entry to or withhold consent to enter" for repairs, inspections, or showings. And because violations of the renter-duty statutes are grounds for forcible entry and detainer under § 1-21-1002, a tenant who stonewalls access is risking eviction, not just a scolding. Best practice is still a written 24-hour-notice clause; courtesy today is evidence of reasonableness later.

Rent, late fees, and the 3-day cushion nobody notices

No rent control exists anywhere in Wyoming, and no city has tried it. Rent increases follow the lease: fixed terms wait for renewal, and month-to-month increases ride on whatever notice your agreement requires.

Late fees have no statutory cap and no mandated grace period. Courts will still trim a fee that looks like a penalty instead of an estimate of your costs, so keep it proportionate and in the signed lease. There is one built-in cushion: eviction proceedings for nonpayment can't start until rent has gone unpaid for 3 days after the due date (§ 1-21-1002). Your late fee can accrue from day one if the lease says so, but the courthouse door doesn't open until day four.

The eviction path: 3 days' notice, then a fast courtroom

Wyoming evictions are forcible entry and detainer (FED) actions, and the fuse is short:

  • Once rent is 3 days overdue, or a renter has violated the duty statutes (§§ 1-21-1204, 1-21-1205), or is holding over after the term, serve a written notice to quit. The tenant gets at least 3 days to comply or leave (§ 1-21-1003). Personal delivery, leaving it at the home, or posting it to the door all work.
  • A tenant who does what the notice demands, paying the rent or correcting the violation, stops the eviction, per the Wyoming Judicial Branch's own guidance.
  • If not, file the FED complaint in circuit court. The summons must be served 3 to 12 days before the trial date, so hearings land fast.
  • Win, and the court issues a writ of restitution. Judges set the move-out window anywhere from 0 to 30 days, with the sheriff enforcing removal (§ 1-21-1211).

What you may not do is skip the courthouse: lockouts, utility shutoffs, and hauling possessions to the street aren't authorized by any Wyoming statute, and they convert a winnable FED case into your liability problem. Property a departed tenant leaves behind has its own rule: written notice and a 7-day response window before you may dispose of it (§ 1-21-1210).

The contrast with the region is stark. Colorado now requires cause to end most tenancies; Wyoming will hear your 3-day nonpayment case the same month you file it. That speed is why out-of-state owners keep buying in Cheyenne and Casper, and why Wyoming tenants read leases carefully.

Habitability: real duties, narrow remedies

Since 1999, the Residential Rental Property Act has required owners to keep units "reasonably safe, sanitary and fit for human occupancy," with operational electrical, heating, and plumbing systems and hot and cold running water, and to maintain common areas and any appliances the lease includes (Wyo. Stat. §§ 1-21-1202, 1-21-1203). You don't have to repair damage the renter or their guests caused.

The tenant's remedy path is unusually procedural (§ 1-21-1206): first a written notice of the problem, then, if a reasonable time passes without a fix, a notice to repair sent by certified mail. Only after the owner fails to act within 3 more days may the renter sue in circuit court, where judges can award damages, order repairs, or refund rent. Wyoming gives tenants no rent-withholding right and no repair-and-deduct. Fix furnaces promptly anyway; a documented habitability breach is the one defense that reliably slows your FED case down.

Disclosures are nearly a null set. State law requires the nonrefundable-deposit statement from the intro (§ 1-21-1207), and pre-1978 housing triggers the federal lead-based paint disclosure. That's the list.

What changed in 2024 to 2026: one squatter law, otherwise quiet

Wyoming's legislature left landlord-tenant law essentially untouched in 2024, and the 2026 budget session produced nothing notable on rentals either. The one real change: Senate File 6, the unlawful-occupant removal law, became law in February 2025 and took effect July 1, 2025.

SF0006 lets a property owner ask law enforcement to immediately remove occupants who have no lease, were never tenants, and aren't the owner's relatives, no FED filing required. It also criminalizes presenting false property documents (fake deeds and phantom leases) and adds a felony tier for serious property destruction by unlawful occupants. If someone moves into your vacant unit uninvited, the sheriff, not the eviction docket, is now the right first call. For actual tenants, even badly behaved ones, the FED process above still governs.

Wyoming landlord FAQ

How fast does a Wyoming landlord have to refund the deposit?

Thirty days after the tenancy ends, or 15 days after you receive the renter's new mailing address, whichever is later, with 30 extra days if the unit is damaged (§ 1-21-1208). Send the itemization on time even when deductions are obvious; an unreasonable delay forfeits the whole deposit plus court costs.

Can I charge a nonrefundable cleaning or pet fee?

Yes, but only if the rental agreement states the fee is nonrefundable and you also give written notice of that when you take the money (§ 1-21-1207). Skip either step and the fee is treated as a refundable deposit.

How fast can I evict for nonpayment?

Rent must be 3 days overdue, then a 3-day notice to quit, then an FED filing with the summons served 3 to 12 days before trial (§§ 1-21-1002, 1-21-1003). Start to writ can run under three weeks, though the judge may give the tenant up to 30 days to move.

How much notice must I give to end a month-to-month tenancy?

No Wyoming statute sets a period. Whatever your lease says controls, and 30 days is the accepted custom courts expect when the agreement is silent. Put a specific number in every month-to-month agreement.

Do I have to give notice before entering a unit?

No statute requires advance notice, but renters may not unreasonably refuse entry for repairs, inspections, or showings (§ 1-21-1205). A written 24-hour-notice clause keeps entries reasonable, documented, and drama-free.
