Illinois: Month-to-Month Tenancy Termination Notice Requirements
The short answer
To end an Illinois month-to-month tenancy with no fault, the landlord gives 30 days' written notice (735 ILCS 5/9-207(b)); a week-to-week tenancy takes 7 days. A tenant ending a month-to-month tenancy gives the same 30 days' written notice. The statute does not force the end date onto a particular day of the month, though the 30-day notice is customarily served so it runs to the end of a rental period. Illinois has no statewide just-cause law, so a no-cause termination needs no reason under state law — but Chicago, Cook County, and some other localities add longer notice periods that increase with how long the tenant has lived in the unit, so local law can change the answer.

| Governing law | 735 ILCS 5/9-207 ('Notice to terminate tenancy for less than a year'), in the Eviction Article of the Code of Civil Procedure, with service governed by 735 ILCS 5/9-211. A month-to-month tenancy is a 'tenancy for any term less than one year,' so a landlord terminates it on 30 days' written notice under § 9-207(b) (a week-to-week tenancy takes 7 days, § 9-207(a)). The section is written from the landlord's side, addressing a tenant who 'holds over without special agreement.' A separate 90-day rule in § 9-207.5 applies only to residential real estate in foreclosure. Scope: a no-fault end of a month-to-month tenancy; nonpayment and lease-violation removals, which carry their own shorter notices, belong to the separate eviction survey |
|---|---|
| Landlord's notice period | 30 days' written notice. For a 'tenancy for any term less than one year, other than tenancy from week to week ... the landlord may terminate the tenancy by 30 days' notice, in writing' (§ 9-207(b)), and a month-to-month tenancy is such a tenancy. A week-to-week tenancy takes 7 days (§ 9-207(a)). There are no occupancy-length tiers under state law. The § 9-207.5 90-day period is a foreclosure-only exception — a new owner or mortgagee ending a lease after a judicial sale — not an ordinary landlord's clock |
| Tenant's notice period | 30 days, by long-settled practice. Section 9-207 expressly addresses only the landlord's termination of a holdover tenant, so the tenant's clock is not fixed by its text; a tenant ending a month-to-month tenancy gives 30 days' written notice — a full rental period — under Illinois common law. The lease may set the tenant's notice terms, because the § 9-207(b) default applies only 'without special agreement' |
| When termination takes effect | 30 days from notice; the statute does not tie the end date to a rental period. Section 9-207(b) requires '30 days' notice, in writing' but says nothing about aligning the termination date with the end of a monthly period. In practice the 30-day notice for a month-to-month tenancy is served so it expires at the end of a rental period (for a first-of-the-month tenancy, given a full month before the month it is meant to end) — but that period-alignment comes from practice, not the statute's text, so confirm how the local court applies it before counting days |
| Form and required contents | Written. Both § 9-207(a) and (b) require the notice to be 'in writing.' Beyond writing, the statute prescribes no particular contents and no mandatory statement or form for a no-fault month-to-month termination |
| How notice must be delivered | Governed by § 9-211. Notice may be served 'by delivering a written or printed ... copy thereof to the tenant, or by leaving the same with some person of the age of 13 years or upwards, residing on or in possession of the premises; or by sending a copy of the notice to the tenant by certified or registered mail, with a returned receipt from the addressee; and in case no one is in the actual possession of the premises, then by posting the same on the premises' (§ 9-211). Posting is allowed only when no one is in possession — a common landlord mistake |
| What the lease can change | The statutory 30-day default fills in 'where the tenant holds over without special agreement' (§ 9-207(b)) — a 'special agreement' (a lease term) can set the tenancy's own termination terms. The statute does not itself spell out how far a lease may shorten the notice, and § 9-207 contains no anti-waiver clause; Illinois courts look first to the lease for the tenancy's terms. Read the lease's termination and notice clauses |
| Just-cause limits | No statewide just-cause law. Illinois does not require a landlord to have a reason to end a month-to-month tenancy; a proper 30-day notice needs no cause under state law. Local law is a real overlay here: Chicago, Cook County, and some other Illinois jurisdictions require longer notice periods that increase with how long the tenant has lived in the unit, plus other protections — check the ordinance for the property's location. A defective notice is a defense in the landlord's eviction case, not a source of statutory damages |

Requirements one by one
Governing law
Illinois keeps the periodic-tenancy rule in its Eviction Article: 735 ILCS 5/9-207,
"Notice to terminate tenancy for less than a year." A month-to-month tenancy is a
"tenancy for any term less than one year," so it falls under subsection (b) — 30 days'
written notice. (A week-to-week tenancy takes 7 days under subsection (a).) The section
is written from the landlord's perspective, dealing with a tenant who "holds over
without special agreement," and how to serve the notice is set out separately in
§ 9-211. This page is about an ordinary no-fault termination; removals for unpaid rent
or a lease violation carry their own shorter notices and run through the eviction
process covered in a separate survey.
Landlord's notice period
For a month-to-month tenancy, "the landlord may terminate the tenancy by 30 days'
notice, in writing" (§ 9-207(b)). There are no tiers based on how long the tenant has
lived there under state law — 30 days is the figure regardless. The one place a
different, longer number appears in this part of the Code is § 9-207.5, which requires
90 days' notice, but only in a narrow situation: a bank, receiver, or buyer that takes
over residential property through foreclosure and wants to end an existing lease. An
ordinary landlord ending an ordinary month-to-month tenancy uses the 30-day rule.
Tenant's notice period
The statute speaks only to the landlord, so the tenant's clock is not spelled out in
§ 9-207 itself. Under long-settled Illinois practice, a tenant ends a month-to-month
tenancy the same way — 30 days' written notice, a full rental period. The lease can set
the tenant's notice terms, because the statutory default applies only "without special
agreement." If you are the tenant, read your lease first, then plan on at least 30 days
if it is silent.
When termination takes effect
Section 9-207(b) fixes the length of the notice — 30 days — but does not say the
tenancy has to end on any particular day of the month. In everyday practice, though, a
month-to-month notice is served so that the 30 days run to the end of a rental period:
for a tenancy whose month runs from the 1st, a landlord who wants the tenancy to end on
July 31 serves the notice by around the end of June. That period-alignment is a matter
of practice rather than something the statute's words require, so if the exact
end date matters, confirm how your local court expects the 30 days to be counted before
you rely on a particular move-out date.
Form and required contents
The notice must be in writing — both subsections of § 9-207 say "in writing." The
statute does not prescribe any particular wording, and there is no mandatory statement
or official form for a no-fault month-to-month termination. A dated written notice that
clearly states the tenancy is ending and gives the move-out date is what the statute
calls for.
How notice must be delivered
Service is where Illinois landlords most often go wrong, because § 9-211 is specific.
Notice may be served by handing a copy "to the tenant"; by "leaving the same with some
person of the age of 13 years or upwards, residing on or in possession of the
premises"; or "by sending a copy of the notice to the tenant by certified or registered
mail, with a returned receipt from the addressee." Posting is a last resort: it is
permitted only "in case no one is in the actual possession of the premises." Tacking a
notice to an occupied unit's door instead of using one of the first three methods is a
frequent, case-losing mistake.
What the lease can change
The 30-day rule is a default that applies "where the tenant holds over without special
agreement" (§ 9-207(b)). A "special agreement" — the lease — can set the tenancy's own
termination terms, so the lease is the first place to look. The statute does not itself
say how far a lease may cut the 30 days, and, unlike some other states' termination
statutes, § 9-207 has no clause voiding a waiver. Illinois courts look to the lease for
the terms of the tenancy, so a signed lease's notice clause generally controls.
Just-cause limits
Under state law there is no just-cause requirement: a landlord ending a month-to-month
tenancy needs no reason, and a proper 30-day notice is enough. Local law is the
important caveat in Illinois. Chicago, suburban Cook County, and a number of other
Illinois jurisdictions require notice periods that grow with how long the tenant has
lived in the unit — well beyond 30 days for longer tenancies — and add other tenant
protections. Because those local rules can more than double the state notice period,
always check the ordinance for the municipality where the rental sits. If a landlord's
notice is defective, the tenant raises that as a defense in the eviction case; it is not
a statutory-damages claim under § 9-207.
What trips people up
Posting the notice on an occupied door is not valid service. Section 9-211 allows
posting only "in case no one is in the actual possession of the premises." For an
occupied unit, you must personally deliver the notice, leave it with someone 13 or older
who lives there, or send it by certified or registered mail with a return receipt.
Improper service is one of the most common reasons Illinois eviction cases get dismissed.
Local law often requires far more than 30 days. The 30-day figure is the state
floor. In Chicago and Cook County, ending or not renewing a month-to-month tenancy can
require 60 or more days depending on how long the tenant has lived there. The state
answer can be badly wrong for a specific address without checking the local ordinance.
The 90-day rule is only about foreclosures. Section 9-207.5's 90-day notice applies
when a bank or a foreclosure-sale buyer takes over the building and wants to end an
existing lease. It does not lengthen the notice an ordinary landlord owes on a
month-to-month tenancy.
Common questions
I'm an Illinois landlord ending a month-to-month tenancy. How much notice? Thirty
days' written notice (§ 9-207(b)) — unless a local ordinance where the property sits
requires more, which in Chicago and Cook County it often does. Serve it using one of the
methods in § 9-211.
Can I just tape the notice to the tenant's door? Not if someone is living there.
Posting is allowed only when no one is in possession (§ 9-211); otherwise use personal
delivery, delivery to a resident 13 or older, or certified/registered mail with a return
receipt.
I'm the tenant — how much notice do I give to move out? The statute addresses the
landlord's side, but the recognized rule for a tenant ending a month-to-month tenancy is
the same 30 days' written notice; check your lease, which can set the terms.
Does my landlord need a reason to end my month-to-month tenancy? Not under Illinois
state law — there is no statewide just-cause rule. But some Illinois cities and counties
require longer notice and additional protections, so check the local ordinance.
