Wyoming: Month-to-Month Tenancy Termination Notice Requirements

How ending a month-to-month tenancy works in Wyoming

Wyoming is a minimal-statute state for this question. Unlike most states, it has no
statute that sets a notice period for ending an ordinary month-to-month (or other
periodic) tenancy with no cause. The Residential Rental Property Act (Wyo. Stat.
§§ 1-21-1201 to 1-21-1211) governs habitability, security deposits, and abandoned
property, but it never fixes how many days' notice a landlord or tenant must give to end
a periodic tenancy. Its own definition of "termination" lists the ways a rental
agreement can end — "expiration of the rental period, voluntary termination by mutual
agreement of the parties, termination in accordance with W.S. 1-21-1203(d) [the owner's
repair-cost termination], abandonment ... or termination resulting from court order"
(§ 1-21-1201(a)(v)) — and none of those is a no-cause termination on statutory notice.

So the notice needed to end the tenancy itself comes from the lease and Wyoming common
law, not a statute. If your lease says how much notice each side must give (30 days is a
common lease term, but it is not a state-law requirement), that controls. If the lease is
silent, common-law principles for periodic tenancies apply. This is different from a
state like neighboring Montana, where a statute fixes 30 days.

There is one statutory notice that does apply, but it is a different thing: before a
landlord can file an eviction — a forcible entry and detainer action — the landlord
must serve a written "notice to quit." It "shall be served at least three (3) days
before commencing the action, by leaving a written copy with the defendant or at his
usual place of abode or business if he cannot be found" (§ 1-21-1003). That 3-day notice
is a pre-suit step, and it is uniform for any cause — holding over, unpaid rent, or a
lease violation (§ 1-21-1002(a)(i)). It is not a substitute for ending the periodic
tenancy first: it is the notice you serve before going to court once the tenancy has
already ended or the rent is unpaid.

Two more points. Because there is no statutory notice period, the lease is effectively
where the notice term lives — the Act allows any duty to be "assigned to a different
party or modified by explicit written agreement signed by the parties" (§ 1-21-1202(d)),
and there is no statewide anti-waiver bar on a notice term. And Wyoming has no statewide
just-cause law: a landlord does not need a reason to end a no-cause periodic tenancy,
and no relocation payment is owed under state law. A separate Wyoming Safe Homes Act lets
a domestic-violence or sexual-assault victim end a lease early on short written notice,
but that is a different, fault-free early-exit track outside this survey.

What trips people up

"30 days" is a lease custom, not a Wyoming statute. Many Wyoming leases require 30
days' notice, and many guides repeat it, but no state statute sets that number. Read your
lease — the notice period it names is the one that binds you.

The 3-day notice to quit is not how you end a month-to-month tenancy. Section
1-21-1003's 3-day notice is the pre-suit step before an eviction lawsuit (§ 1-21-1002),
uniform for any cause. Ending a no-cause periodic tenancy is a separate matter set by the
lease and common law.

A landlord still cannot lock you out. Even with no statutory notice period, the
landlord's route to remove a holdover tenant is a forcible entry and detainer action in
circuit court after the 3-day notice to quit (§§ 1-21-1002, 1-21-1003) — not a self-help
lockout or utility shutoff.

Common questions

How much notice do I have to give to move out of a month-to-month rental in Wyoming?
There is no state-law number. Whatever your lease requires controls; if the lease is
silent, common-law rules for periodic tenancies apply. Give written notice and keep proof
of when you gave it.

Can my landlord end my month-to-month tenancy without a reason? Yes. Wyoming has no
statewide just-cause law, so a landlord may end a no-cause periodic tenancy for any
reason, subject to fair-housing law and whatever notice the lease requires. To remove you
if you stay, the landlord must serve a 3-day notice to quit and file an eviction
(§§ 1-21-1002, 1-21-1003).

Isn't the notice to quit only 3 days? The 3-day "notice to quit" (§ 1-21-1003) is the
pre-suit notice before an eviction lawsuit — it is not the notice that ends a
month-to-month tenancy. Those are two separate things in Wyoming.

  applicable statutory landlord notice, and it is a pre-suit step, not a periodic-tenancy
