Rent late fee policy template for Illinois landlords

By Al Kolovic, Chicago landlord and Illinois real estate broker

A clear late fee policy tells your tenant exactly when rent is late, what it costs, and what you won’t charge. Below are the Illinois rules, a table of the maximum fee in Chicago and suburban Cook County, and a fill-in policy you can attach to your lease.

The short version

Chicago (RLTO units): at most $10 a month on the first $500 of rent, plus 5% a month of the rent above $500.
Suburban Cook County (RTLO units): at most $10 a month on the first $1,000 of rent, plus 5% a month of the rent above $1,000.
Evanston and some other towns: their own ordinance sets their own rule. Check your town.
Rest of Illinois: no state law sets a dollar cap, but a late fee has to be a reasonable estimate of your cost, not a penalty.
Everywhere: one late fee a month is the safe pattern. No daily fees, and from January 1, 2027, no fees for an eviction notice on leases covered by the new state fee law.

Chicago: the RLTO limit

For units covered by the Chicago Residential Landlord and Tenant Ordinance, a lease can’t make the tenant pay “a charge, fee or penalty in excess of $10.00 per month for the first $500.00 in monthly rent plus five percent per month for any amount in excess of $500.00 in monthly rent for the late payment of rent” (Chicago Municipal Code 5-12-140(h)).

No disguised late fees. A discount for paying early can’t be bigger than the same formula (5-12-140(i)). “Rent is $1,600, or $1,500 if paid by the 1st” is a $100 late fee in disguise.
The penalty. A lease clause that breaks these rules is unenforceable. If a landlord tries to enforce it, the tenant can recover two months’ rent (5-12-140).

Who’s covered: most Chicago rentals. Owner-occupied buildings with six or fewer units are excluded, along with a few other housing types (5-12-020).

Suburban Cook County: the RTLO limit

For units covered by the Cook County Residential Tenant and Landlord Ordinance, a lease can’t make the tenant pay “a charge, fee or penalty in excess of $10.00 per month for the first $1,000.00 in monthly rent plus five (5) percent per month for any amount in excess of $1,000.00 in monthly rent for the late payment of rent” (Cook County Code 42-104(f)(9)).

Early-payment discounts are capped by the same formula (42-104(f)(10)).
Rent goes to rent first. A lease can’t let the landlord apply rent payments to other charges, “including but not limited to utilities, fines, late fees or other charges” (42-104(f)(11)). So you can’t take this month’s rent payment, apply it to last month’s late fee, and then call the rent short.
No required grace period. The RTLO doesn’t set one. Its 5-day rule is for the eviction notice, not the late fee.
The penalty. If a landlord deliberately uses a lease with a provision they know is prohibited, the tenant can recover actual damages or two months’ rent, whichever is greater (42-104(g)).

Who’s covered: rentals in Cook County outside Chicago, except:

towns that have their own landlord-tenant ordinance (42-101(d));
owner-occupied buildings with six or fewer units;
a single-family home or condo, when all of these are true: it’s the one unit the owner rents out, the owner or their family lived there for at least a month in the 12 months before it was listed, the owner manages it personally, and the owner isn’t a corporation. These owners must say the unit is exempt in their ads and applications (42-102).

Towns with their own rules. Some suburbs have their own ordinance. For example:

Evanston: for leases starting on or after January 1, 2025, the cap is $25 when rent is $1,600 or less, or $25 plus 5% of the rent above $1,600.
Oak Park: the same $10 + 5% formula as the County, and the same rent-first rule.
Mount Prospect: has its own landlord-tenant ordinance. Check it before you set a late fee.

If your town has its own ordinance, follow it.

Rest of Illinois: the reasonableness rule

Outside Chicago and suburban Cook County, no Illinois statute sets a dollar limit on apartment late fees. (The “$20 or 20%” figure some sites quote comes from the law for self-storage units, not homes.)

What limits a late fee is contract law. Illinois courts enforce a preset charge only if it’s a reasonable estimate of a loss that’s hard to measure. A charge that works as a threat to force payment is an unenforceable penalty. In one Illinois case about a condo association’s late charges, a court struck down a $25 monthly charge that kept stacking up, but said a one-time $25 charge would have been reasonable (Hidden Grove Condominium Ass’n v. Crooks, 318 Ill. App. 3d 945 (2001)).

Some towns have their own ordinance with their own late fee rules. Check yours.

Maximum late fee by rent

Maximum monthly late fee in Chicago and suburban Cook County by monthly rent
Monthly rent	Chicago max	Suburban Cook max
$900	$30 $10 + 5% of $400	$10
$1,200	$45 $10 + 5% of $700	$20 $10 + 5% of $200
$1,500	$60 $10 + 5% of $1,000	$35 $10 + 5% of $500
$1,800	$75 $10 + 5% of $1,300	$50 $10 + 5% of $800
$2,200	$95 $10 + 5% of $1,700	$70 $10 + 5% of $1,200

These are monthly maximums under each ordinance. A lower fee is always allowed.

The 2027 state fee law

A new Illinois law (765 ILCS 705/35) applies to leases signed after January 1, 2027, except in owner-occupied buildings with six or fewer units:

Every non-optional fee has to be on the first page of the lease, or the tenant doesn’t owe it. The law doesn’t mention late fees. Listing your late fee on page 1 anyway keeps things clear, and our free Illinois lease does that.
No fee or fine “for an eviction notice or the filing of an eviction action prior to the court granting an eviction order.” So no “notice fee” on top of the late fee. Court costs and filing fees the law allows are separate.

What a good late fee policy includes

The due date, and how rent is paid.
The grace period in days, and what counts as “received”.
One flat late fee per month, within the limit for your area.
No daily fees, no fees on unpaid fees, no notice fees.
How partial payments are applied (in suburban Cook County and Oak Park, rent first).
That accepting late rent and a late fee doesn’t change the lease.
Where the fee appears: page 1 of the lease, and on the tenant’s ledger.

The template

Copy it into your document and fill in the brackets. It’s the same policy that’s in the late rent kit.

Late Fee Policy
Property: [Property address, unit]
Landlord: [Landlord name] Tenant(s): [Tenant names]
This policy is part of the lease dated [Lease date]. If it conflicts with the lease or with the law, the lease and the law control.

1. When rent is due. Rent of $[Monthly rent] is due on the [Due day, e.g. 1st] day of each month. Rent can be paid by [payment methods]. A payment counts as received on the day [it arrives in Landlord’s account / Landlord receives the check].

2. Grace period. If rent is not received by the end of day [Grace days] after the due date, rent is late.

3. Late fee. When rent is late, Tenant owes one late fee of $[Late fee amount] for that month. The late fee will never be more than the limit set by the law or ordinance that applies to the property:

[ ] City of Chicago (RLTO): $10 on the first $500 of monthly rent, plus 5% of monthly rent above $500. On this lease, that limit is $[calculated].
[ ] Suburban Cook County (RTLO): $10 on the first $1,000 of monthly rent, plus 5% of monthly rent above $1,000. On this lease, that limit is $[calculated].
[ ] Elsewhere in Illinois, or a town with its own ordinance: the late fee is a reasonable estimate of Landlord’s cost from late payment and is not a penalty, and it is within any local ordinance limit.

4. What Landlord will not charge. There are no daily late fees, no late fees on unpaid late fees, and no fee for sending a reminder or a notice. [For leases covered by 765 ILCS 705/35: no fee for an eviction notice or for filing an eviction case before a court grants an eviction order.]

5. Returned payments. If a payment is returned unpaid by Tenant’s bank, Tenant owes a returned payment fee of $[Amount, or “none”], and the payment counts as not received.

6. How payments are applied. Payments are applied to rent first, then to other charges [required in suburban Cook County and Oak Park].

7. Where the fee is listed. This late fee [is / will be] listed on page 1 of the lease.

8. No waiver. Accepting a late payment or a late fee doesn’t change any other part of the lease.

Questions landlords ask

What is the maximum late fee for rent in Illinois?

There’s no statewide dollar cap. In Chicago (RLTO units) the maximum is $10 on the first $500 of monthly rent plus 5% of the rest. In suburban Cook County (RTLO units) it’s $10 on the first $1,000 plus 5% of the rest. Some towns, like Evanston, set their own limit. Elsewhere, the fee must be reasonable, not a penalty.

Can I charge a daily late fee in Chicago?

The RLTO limit is per month. A daily fee that adds up past the monthly limit isn’t allowed, so most Chicago landlords charge one flat fee.

Is a grace period required in Illinois?

Not for apartments. The Chicago RLTO, the Cook County RTLO and state law don’t set a required number of grace days before a late fee. Your lease sets the grace period, so pick a number and apply it the same way to every tenant.

Can I offer a discount for paying early instead of a late fee?

In Chicago and suburban Cook County, an early-payment discount is capped by the same formula as the late fee, so it can’t be used to get around the limit.

Does the 2027 Illinois fee law cap late fees?

No. It requires non-optional fees to be on the first page of the lease and bans some fees, like eviction notice fees, but it doesn’t set a late fee amount.

Do the Chicago limits apply if I live in my two-flat?

No. Owner-occupied buildings with six or fewer units are excluded from most of the RLTO, including the late fee limit. A few Chicago rules still apply to them, such as the lockout ban and the notice rules for ending a lease (5-12-130(j)).
