How many days' notice must a landlord give before raising rent in Wyoming?

No rent-increase statute — notice derives from tenancy-termination rules (see summary).

Does Wyoming have rent control?

No — Wyoming has no statewide rent control or stabilization. Wyoming has no statewide rent control and no statute authorizing it, and no rent-control ordinance appears in the published codes of the 30 Wyoming cities and towns searched.

Does Wyoming preempt local rent control ordinances?

No Wyoming statute expressly addresses local rent control — the legislature has neither authorized nor prohibited city or county regulation of rent amounts. A 2023 bill that would have barred cities, towns and counties from regulating the leasing of residential rental property died in committee.

Can a landlord raise the rent during a fixed-term lease in Wyoming?

Rent is fixed for the lease term as a matter of contract, and no Wyoming statute permits or regulates mid-term or renewal increases.

How much notice is required to raise the rent in Wyoming?

Wyoming has no statute requiring any advance notice of a rent increase — and unlike most no-notice states, it has no statutory month-to-month termination notice to derive a working rule from either.

The rental agreement is everything: if a written month-to-month agreement sets an increase or notice mechanism, that contract governs; if not, Wyoming's distinctive holdover statutes take over. Under W.S. 34-2-128, no landlord-tenant relationship arises by implication or operation of law except a tenancy by sufferance — a tenant who stays past the lease term gets no implied renewal even if the landlord keeps accepting rent — and under 34-2-129 an expired lease can only be renewed by a signed written contract. A holdover tenant at sufferance can face an eviction on the only statutory notice Wyoming has: the 3-day notice to quit that must precede a forcible entry and detainer action. There is no rent control anywhere in the state, no limit on the size or frequency of increases, and no statute either authorizing or forbidding local rent regulation, and no rent-control ordinance appears in the published codes of the 30 Wyoming cities and towns searched.

Wyoming rent increase notice at a glance

Notice — month-to-month	No rent-increase statute — notice derives from tenancy-termination rules (see summary)
Varies by increase size	Not addressed by statute
Fixed-term leases	Rent is fixed for the lease term as a matter of contract, and no Wyoming statute permits or regulates mid-term or renewal increases. Wyoming adds a twist no other state matches: an expired lease can be renewed ONLY 'by express contract in writing, signed by the parties' (W.S. 34-2-129), and a tenant who holds over — even with the landlord accepting rent — gets no implied renewal at all, only a tenancy by sufferance (W.S. 34-2-128).
Statewide rent control / stabilization	No
Rent control details	Wyoming has no statewide rent control and no statute authorizing it, and no rent-control ordinance appears in the published codes of the 30 Wyoming cities and towns searched. Title 15 (cities and towns) and the landlord-tenant articles contain no rent-control provision of any kind; the only 'low-rent' language in Title 15 concerns municipal housing-authority projects.
Local rent regulation	No Wyoming statute expressly addresses local rent control — the legislature has neither authorized nor prohibited city or county regulation of rent amounts. A 2023 bill that would have barred cities, towns and counties from regulating the leasing of residential rental property died in committee.
Frequency limits	Not addressed by statute

Notes and caveats

Why the month-to-month field is blank — Wyoming not only has no rent-increase notice statute — it has no month-to-month termination notice statute to reason from either. The phrases 'month-to-month' and 'periodic tenancy' appear nowhere in Titles 1, 15 or 34.
The lease is the whole framework — an express month-to-month agreement can be changed or ended per its own terms; common-law periodic-tenancy notice rules operate, if at all, only inside such an express tenancy. The early case McNamara v. O'Brien, 2 Wyo. 428 (1881), is tenancy-at-sufferance background only.
Holdover means sufferance, not renewal — a tenant who stays on without a new signed agreement holds only a tenancy at sufferance (§§ 34-2-128, 34-2-129), evictable after the 3-day notice to quit (§ 1-21-1003; grounds at § 1-21-1002(a)).
Debunk: no rent-control preemption statute exists — secondary sources claim Wyoming 'expressly prohibits' local rent control 'codified at Wyo. Stat. § 1-21-1201 et seq.' and that courts have 'consistently upheld' the preemption. No preemption or rent-control language exists anywhere in Article 12, and no such case law exists.
Debunk: the '15 days' written notice' rule is invented — A widely read 2026 landlord guide states a '15 days' written notice' rule for month-to-month increases. No statute says this; the figure appears lifted from § 1-21-1208(a)'s deposit clock, and the same guide miscites § 1-21-1203 (owner repair duties) as an entry statute.
Local control: unaddressed and untested — no statute preempts local rent regulation, none authorizes it, and no rent-control ordinance appears in the published codes of the 30 Wyoming cities and towns searched. Municipalities have constitutional home rule (Wyo. Const. art. 13, § 1) subject to statute, so the question is untested.
Nothing on rent was introduced in 2025 or 2026 — Titles 1, 15 and 34 carry no rent-increase or rent-control provision, and neither the 2025 nor the 2026 session saw a rent bill of any kind introduced, as of July 12, 2026.

How this record was verified: Direct read of statute text in the Wyoming Legislative Service Office's compiled title files (wyoleg.gov/statutes/compress/title01.pdf, title34.pdf, title15.pdf, title40.pdf) on October 1, 2026. The files were compiled on May 8, 2026 and include the 2026 Budget Session. Title 1 ch. 21 art. 12 (W.S. 1-21-1201 through 1-21-1211) and art. 10 (1-21-1001 through 1-21-1017) read in full, plus W.S. 34-2-126 through 34-2-132; Articles 10 and 12 read the same in the Legislature's online statute view. Deposit figures were also read in the Wyoming Judicial Branch's TENANT-03 instructions (wyocourts.gov, rev. September 2024), which reprint W.S. 1-21-1208. Negatives (no deposit cap, no interest or separate-account rule beyond the express 'without interest' clause, no rent-increase or periodic-termination notice statute, no late-fee cap or grace period, no entry-notice statute, no rent-control or preemption provision) rest on full-article reads plus keyword searches of every title: zero occurrences of 'month-to-month', 'late fee', 'late charge' or 'grace period' in Titles 1, 15 and 34. Session check on the Legislative Service Office's bill records: all 278 enrolled acts of the 2025 General Session (171) and the 2026 Budget Session (107) were read for amendments to these sections; none amends W.S. 1-21-1001 through 1-21-1017, 1-21-1201 through 1-21-1211 or 34-2-126 through 34-2-132, and 2025 Senate File 6 (ch. 41) added W.S. 1-21-1401 through 1-21-1403. Dead bills: 2025 HB0213 (owner utility duties) and 2026 HB0183 (renter tax relief), both not considered for introduction. The next regular session is January 2027.
