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

Verified July 12, 2026 All Wyoming topics →

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; 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. Full-text sweeps of Title 15 (cities and towns) and the landlord-tenant articles found no rent-control provision of any kind; the only 'low-rent' language in Title 15 concerns municipal housing-authority projects.
Local rent control preempted Not addressed by statute
Frequency limits Not addressed by statute

Notes and caveats

notice_days_month_to_month null per the derivation convention (TX/NE/MS/WV/MT/AK precedent), but flag for page copy that Wyoming is BARER than the rest of that camp: zero occurrences of 'month-to-month' or 'periodic tenancy' in Titles 1, 15 and 34 (full-text sweeps), so there is not even a termination-notice grid to derive from. The working framework is contractual: express m2m agreements are terminable/changeable per their 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 sufferance background only), while holdover without a new signed agreement yields only a tenancy at sufferance (34-2-128/129) evictable after the 3-day notice to quit (1-21-1003; FED grounds at 1-21-1002(a)). TWO HIGH-TRAFFIC DEBUNKS: (1) 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 (read in full on three official endpoints) and no such case law exists; same fabrication class as Alaska's phantom § 34.03.020 sentence. (2) Hemlane's 2026 Wyoming page invents a '15 days' written notice' rule for m2m increases — no statute says this; the figure appears lifted from § 1-21-1208(a)'s deposit clock, and the page also miscites § 1-21-1203 (owner repair duties) as an entry statute. local_control_preempted null (NV/WV/AK precedent): no express preemption, no authorization, no ordinance has ever existed; Wyoming municipalities have constitutional home rule (Wyo. Const. art. 13, § 1) subject to statute, and the question is untested. Session sweep 2025+2026: no rent bill of any kind introduced.

Statute citations

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 wyoleg.gov site is an SPA that serves its statute PDFs directly to curl; 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 (Justia 403s automated fetchers). 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. Mandatory 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.
