Chicago Rent Increase Notice in 2026: When 60 Days Applies at Lease Renewal
Chicago generally requires 60 days' written notice before a rent increase for a residential tenancy lasting six months to three years. Learn how lease-end timing, late notice, the 30/60/120-day tiers, small owner-occupied buildings, and the Jackson Park pilot fit together.
The short answer
Chicago Municipal Code section 5-12-130(j) generally requires a landlord to give written notice before increasing rent, declining to renew a fixed-term lease, or terminating a periodic tenancy. For a residential tenancy lasting from six months to three years, the current citywide baseline is at least 60 days before the stated termination date.
A lease ending sooner does not automatically erase that notice requirement. The correct analysis starts with how long the tenancy has lasted, the date written notice was actually given, the proposed effective date, the property address, and whether a special local rule such as the Jackson Park Expanded Fair Notice Pilot Program applies.
Chicago's citywide baseline is 30, 60 or 120 days
Section 5-12-130(j) currently uses three citywide notice tiers: at least 30 days for a residential tenancy of less than six months, at least 60 days for a tenancy of six months to three years, and at least 120 days for a tenancy greater than three years.
Those notice periods apply to a landlord's stated intent to terminate a periodic tenancy, not renew a fixed-term rental agreement, or increase the rental rate. The tenancy-duration tier therefore matters before deciding whether a rent increase can take effect on the date proposed by management.
What if the landlord gives the notice too late?
For the six-month-to-three-year tier, the current text of section 5-12-130(j)(2) says that if the landlord gives insufficient or defective notice, or otherwise fails to give the required written notice, the tenant may remain in possession for up to 60 days after the date written notice is given, regardless of the termination date in the notice or existing rental agreement.
The section also states that during that occupancy the tenancy terms and conditions remain the same as during the month immediately preceding the notice, with a special rule when rent had been waived or abated. Whether that remedy applies to a particular dispute can depend on the facts, so preserve the lease, notice and payment record rather than relying only on an informal summary.
A text message can be evidence, but notice validity can be fact-specific
The ordinance requires notice in writing. If a landlord communicates a proposed increase by text, email, portal message or letter, preserve the complete message and the date it was received because it can be important evidence of timing and content.
This guide does not determine whether a particular text message or electronic communication satisfies every applicable notice or service requirement. Review the lease, the ordinance, any required delivery method and the exact communication before treating an informal message as legally sufficient or insufficient.
The Fair Notice rule reaches some small owner-occupied buildings
Chicago Municipal Code section 5-12-020 excludes several categories from much of Chapter 5-12, including many owner-occupied premises containing six units or fewer. But that same exclusion expressly says section 5-12-130(j) still applies to every rented dwelling unit in those owner-occupied premises within Chicago.
That makes it unsafe to assume the Fair Notice rule disappears merely because a rental is in a small owner-occupied building. Other parts of the Residential Landlord and Tenant Ordinance may have different coverage, so the property type and the exact provision at issue still need separate review.
Check the Jackson Park Expanded Fair Notice Pilot before using the citywide timeline
Chicago Municipal Code section 5-12-135 creates a special Fair Notice pilot in a bounded area generally between 60th Street, Dr. Martin Luther King Jr. Drive, South Chicago Avenue, 71st Street and South DuSable Lake Shore Drive. Within the covered pilot area, its notice requirements supersede section 5-12-130(j) during the pilot period.
For covered residential leases in that pilot, the section lists notice periods of at least 90 days for a tenancy of one year or less, 120 days for a tenancy of at least 12 months but no more than three years, and 180 days for a tenancy greater than three years. Because the pilot has geographic and lease-specific language, verify the exact property address and current ordinance before applying those longer periods.
What records should a Chicago renter or landlord keep?
Keep the signed lease and every renewal, the date the tenancy originally began, the current rent, the proposed new rent, the date and method of every notice, screenshots or copies of texts and emails, portal records, envelopes, payment records, and the property address.
If the parties disagree about when a higher rent can take effect, those records can establish the tenancy duration and notice timeline. They are more useful than reconstructing the dates later from memory or relying on a community comment.

Common questions
How much notice is generally required for a Chicago rent increase after about two and a half years?
Under Chicago Municipal Code section 5-12-130(j)(2), a residential tenancy lasting six months to three years generally requires at least 60 days' written notice before a rent increase, nonrenewal or termination, unless a more specific rule applies.
Can a Chicago landlord make a higher rent effective immediately because the lease is ending?
Lease expiration does not by itself eliminate Chicago's Fair Notice requirement. The notice tier, date written notice was given, property location and any special rule should be checked before deciding the lawful effective date.
Does Chicago's Fair Notice rule apply to a small owner-occupied building?
Section 5-12-020(a) says that although many owner-occupied premises with six units or fewer are excluded from much of Chapter 5-12, section 5-12-130(j) still applies to every rented dwelling unit in those premises within Chicago.
Are notice periods longer in part of the Jackson Park area?
Yes. Section 5-12-135 creates a bounded pilot area with special 90-, 120- and 180-day notice periods depending on tenancy duration. Verify the exact address and current ordinance before applying the pilot.
Does a landlord's text message count as the required written notice?
The ordinance requires written notice, but whether a particular text or electronic message satisfies all applicable notice and service requirements can be fact-specific. Preserve the message and review the lease and current ordinance rather than assuming validity either way.
