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. No rent control exists anywhere in Wyoming — no statewide program, no statutory authorization, and no municipal ordinance has ever been adopted.

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, and repeated attempts to preempt local rental regulation have failed to pass.

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 — no Wyoming city has ever tried it.

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	No rent control exists anywhere in Wyoming — no statewide program, no statutory authorization, and no municipal ordinance has ever been adopted. 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, and repeated attempts to preempt local rental regulation have failed to pass.
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. Wyoming appellate authority is thin — McNamara v. O'Brien, 2 Wyo. 447 (1881) is early 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 (e.g. evictionriskmap.com) 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 — Hemlane's 2026 Wyoming page 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 page 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 Wyoming ordinance has ever existed. 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 from the official Wyoming Legislative Service Office statute files (wyoleg.gov/statutes/compress/title01.pdf, title34.pdf, title15.pdf, title40.pdf — the Title 1 file reflects 2025-session repeals and is current through the 2025 General 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. Double-read via a second official endpoint: the LSO NXT infobase ('2021 Titles', wyoleg.gov/NXT/gateway.dll) article views for arts. 12 and 10 — the entire Article 12 text (12,872 normalized characters) is CHARACTER-IDENTICAL between the official 2021 edition and the official 2025 PDF. Deposit figures additionally triple-read against the Wyoming Judicial Branch's TENANT Form 03 instructions (wyocourts.gov, rev. Sept 2024), which reprint W.S. 1-21-1208 verbatim; FED figures corroborated by the Judicial Branch Eviction Handout; FindLaw mirror matched 1-21-1208 and 34-2-128 verbatim. Verified 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) run by full-article reads plus keyword sweeps of Titles 1, 15, 34 and 40 — zero occurrences of 'month-to-month', 'late fee', 'late charge' or 'grace period' in Titles 1/15/34. Session sweep on the official LSO bill API (lsoservice.wyoleg.gov): all 891 bills of the 2025 General and 2026 Budget Sessions enumerated by short title, and all 278 enacted chapters (171 of 2025, 107 of 2026) separately enumerated — zero on-topic enactments; dead bills 2025 HB0213 (owner utility duties) and 2026 HB0183 (renter tax relief) both 'Did not Consider for Introduction'. The 2026 Budget Session has adjourned; next regular session January 2027. September 5, 2026 addendum: the decisive figures touched by the 2025-2026 enactments reviewed that day were re-read on the official host — §§ 1-21-1401 through 1-21-1403 in the Title 1 compilation on wyoleg.gov; the earlier reads stand as recorded.
