Illinois Section 24 Notice: Owner Risk After Paying the GC

This article is for general informational purposes only and is not legal advice. Illinois mechanic’s lien deadlines and defenses are fact-specific. Owners, contractors, and subcontractors should consult qualified Illinois construction counsel promptly after receiving or serving a notice.

Quick Answer

If an Illinois owner receives a Section 24 notice from a subcontractor claiming $200,000, the owner should immediately determine whether the notice was timely, what money remains unpaid under the owner-general contractor contract, whether the owner obtained proper sworn contractor statements before paying the general contractor, and whether any payment was made after notice without retaining enough funds to protect the subcontractor’s claim.

Under the Illinois Mechanics Lien Act, a subcontractor may serve written notice of its claim and the amount due or to become due within the statutory period. See 770 ILCS 60/24. Once an owner is notified as provided by the Act, the owner generally must retain enough money from amounts due or to become due the contractor to satisfy the subcontractor’s claim. Illinois courts repeatedly emphasize that the Act tries to balance two policies: protecting those who improved the property and protecting owners from paying twice when they properly used the statutory safeguards.

Scenario: Owner Gets a $200,000 Section 24 Notice After Paying the GC $200,000

Assume the following:

• Owner-GC contract price: $300,000
• Amount already paid by owner to GC: $200,000
• Unpaid balance under owner-GC contract: $100,000
• Subcontractor’s Section 24 notice: $200,000

The owner’s first reaction is usually: “I already paid the GC. Can the subcontractor still lien my property?”

The answer is: possibly, but the amount and enforceability depend on the timing of the notice, the owner’s compliance with the Mechanics Lien Act, and whether the owner made payments after receiving notice without retaining sufficient funds.

In this scenario, the remaining contract balance is only $100,000, but the subcontractor claims $200,000. That mismatch matters. Illinois law generally protects owners from paying more than the original contract price if they comply with the Act. But an owner who pays the general contractor in violation of subcontractor rights may lose that protection.

What Is a Section 24 Notice in Illinois?

A “Section 24 notice” refers to Section 24 of the Illinois Mechanics Lien Act, which governs written notice by subcontractors and certain parties furnishing labor, materials, fixtures, apparatus, machinery, or services. The statute provides that subcontractors may give notice at any time after contracting with the contractor, and must do so within 90 days after completion of the work, or within 90 days after completion of extra or additional work or final delivery of extra materials. See 770 ILCS 60/24.

A Section 24 notice should identify:

• the owner;
• the contractor who employed the subcontractor;
• the work or materials supplied;
• the property improved; and
• the amount due or to become due.

Section 24 also provides that notice is not necessary when a sworn contractor or subcontractor statement already gives the owner notice of the amount due and to whom it is due. If the statement is incorrect as to the amount, the named subcontractor or material supplier is protected to the extent of the amount named as due or to become due. See 770 ILCS 60/24.

That last point is critical: Illinois lien law is not only about whether the subcontractor sent notice. It is also about what the owner knew, when the owner knew it, and what the owner did with project funds after receiving notice.

What Must the Owner Do After Receiving the Notice?

After an owner receives notice under the Mechanics Lien Act, the owner should stop treating the remaining contract balance as freely payable to the GC. The Act requires the owner to protect known subcontractor claims from funds due or to become due the contractor.

The Illinois Supreme Court explained the statutory sequence in Weather-Tite v. University of St. Francis, 233 Ill. 2d 385, 909 N.E.2d 830 (2009). There, the Court held that a contractor’s sworn statement listing amounts due to a subcontractor gives the owner notice, and the owner must retain funds sufficient to pay subcontractor claims rather than simply pay the GC and trust the GC to pass the money along.

In the $300,000 contract scenario, the owner has already paid $200,000 to the GC and still holds $100,000. If the subcontractor serves a valid $200,000 Section 24 notice before the owner pays the remaining $100,000, the owner should generally retain the unpaid $100,000 rather than pay it to the GC. Paying the GC after notice, without retaining funds for the subcontractor’s claim, can be treated as an improper or wrongful payment under the Act.

The hard question is whether the owner can be liable for the other $100,000 of the subcontractor’s $200,000 claim. That depends heavily on whether the owner complied with statutory protections before making the earlier $200,000 payment.

Does the Owner Have to Pay Twice?

Illinois law tries to prevent unfair double payment when the owner followed the Act. Section 21 of the Mechanics Lien Act provides that, except in specified circumstances, the owner should not be compelled to pay more than the contract price for the improvement unless payment was made to the contractor in violation of the rights of those protected by the Act. See 770 ILCS 60/21.

The owner’s best statutory protection is to require the GC’s sworn statement before payment. Section 5 of the Act requires the contractor to give, and the owner to require before paying the contractor, a sworn statement identifying parties furnishing labor, services, materials, fixtures, apparatus, machinery, forms, or form work and the amounts due or to become due to each. In Weather-Tite, the Illinois Supreme Court held that the sworn statement is designed to put the owner on notice of subcontractor claims and trigger the owner’s duty to protect those claims.

In Contractors’ Ready-Mix, Inc. v. Earl Given Construction Co., Inc., 242 Ill. App. 3d 448, 611 N.E.2d 529 (Ill. App. 1993), the court addressed a situation where a supplier served its Section 24 notice after the owner had already made payments to the contractor. The court held that a Section 24 notice given within the 90-day period did not retroactively make earlier payments wrongful. The subcontractor’s lien was limited to the extent of the owner’s wrongful payment, which in that case was only a small amount that should have been retained.

So, in the scenario:

• If the owner paid the GC $200,000 before receiving the subcontractor’s Section 24 notice, and the owner properly obtained and relied on statutory sworn statements that did not show the $200,000 subcontractor claim, the owner may have a strong argument that the earlier $200,000 payment was not wrongful.
• If the owner paid the GC after receiving notice of the subcontractor’s claim, or after receiving a sworn statement showing the subcontractor was owed money, the owner may face lien exposure for funds that should have been retained.
• If the owner failed to require sworn contractor statements before making payments, the owner’s double-payment protection may be weakened substantially.

What If the Claimant Is a Second-Tier Subcontractor or Supplier?

The analysis can change if the claimant is a lower-tier subcontractor or supplier, meaning the claimant contracted with another subcontractor rather than directly with the GC.

Illinois courts have held that a lower-tier claimant’s recovery from the owner may be limited to the amount still owed to the claimant’s immediate contractor when notice is served, especially where the owner properly relied on sworn statements and had no notice of the lower-tier claim. In Gerdau Ameristeel United States, Inc. v. Broeren Russo Construction, Inc., 2013 IL App (4th) 120547, 992 N.E.2d 27, the court limited secondary subcontractors to their pro rata shares of the funds remaining due to their immediate contractor. Similarly, in GX Chicago, LLC v. Galaxy Environmental, Inc., 38 N.E.3d 60 (Ill. App. 2015), the court held that when sub-subcontractors served lien notices, the relevant fund was the amount owed to their immediate contractor, not the entire amount owed on the owner-general contractor contract.

This is why an owner receiving a $200,000 notice should not assume the number on the notice is the amount the owner must pay. The owner should identify the claimant’s contractual tier and determine what money remains due at that tier.

Owner Checklist After Receiving a $200,000 Section 24 Notice

1. Calendar the Notice Date Immediately

The date of receipt matters because payments made after notice may be treated differently from payments made before notice. Preserve the envelope, certified mail receipt, delivery tracking, email transmittal, and any attachments.

2. Freeze Remaining Payments to the GC Until the Claim Is Sorted Out

If the owner still owes $100,000 on a $300,000 contract, the safest immediate move is usually to hold that remaining balance until counsel reviews the notice, lien waivers, sworn statements, and payment history.

3. Review Every Contractor Sworn Statement

Ask:

• Did the GC provide sworn statements before each payment?
• Did the statements list the subcontractor?
• Did the statements show any amount due or to become due?
• Did the owner have any reason to know the statements were incomplete or false?

Under Weather-Tite, a sworn statement listing a subcontractor’s amount due creates a duty for the owner to retain funds to protect that subcontractor.

4. Review Lien Waivers

The owner should match each GC payment to lien waivers from the GC and listed subcontractors. A GC’s promise that “everyone has been paid” may not be enough if the statutory paperwork says otherwise.

5. Determine Whether the Notice Was Timely and Properly Served

Section 24 generally requires service within 90 days after completion of the subcontractor’s work, or within 90 days after extra or additional work or final delivery of extra material. See 770 ILCS 60/24.

6. Identify Whether the Project Is an Owner-Occupied Single-Family Residence

Special notice rules may apply to owner-occupied single-family residences. The 60-day residential notice is required only when the property is an owner-occupied single-family residence at the time of the work. If the home is vacant, rented out, under new construction and not yet occupied, or a multi-unit building, the 60-day notice requirement does not apply. Even where it does apply, the Act builds in an exception: a late notice preserves the lien to the extent the owner has not paid the contractor for the work before receiving it, and a complete failure to serve will not defeat the lien where the owner suffered no prejudice. See 770 ILCS 60/5(b)(iii); 770 ILCS 60/21(c). In Crawford Supply Co. v. Schwartz, 396 Ill. App. 3d 111, 919 N.E.2d 5 (1st Dist. 2009), the court rejected the argument that failure to serve the 60-day notice automatically invalidated the lien as a matter of law, emphasizing the need to consider prejudice to the owner. For an owner, the practical point is that payments made before a late notice arrives are protected; payments made after it arrives are not.

7. Consider Interpleader or a Section 30-Type Proceeding if Multiple Claimants Exist

When several lien claimants are competing for insufficient funds, court-supervised allocation may be appropriate. Illinois cases such as GX Chicago illustrate how courts can determine the available fund and allocate lien rights.

FAQ: Illinois Section 24 Notices

Can a subcontractor send a Section 24 notice before it finishes work?

Yes. Section 24 says a subcontractor may send written notice at any time after making its contract with the contractor, and must do so within the applicable 90-day period after completion or final extra work/material delivery. See 770 ILCS 60/24.

If the owner already paid the GC, is the owner automatically safe?

No. The owner’s protection depends on whether the payment was made before or after notice, whether the owner required sworn statements, whether the claimant was listed, and whether the owner had knowledge that the payment would impair subcontractor rights.

If the subcontractor claims $200,000 but only $100,000 remains unpaid, what should the owner do?

The owner should generally retain the remaining $100,000 pending legal review. Whether the subcontractor can reach beyond that amount depends on the Act, the payment history, the claimant’s tier, the sworn statements, and whether any prior payments were wrongful.

Does a Section 24 notice mean a lien has already been recorded?

Not necessarily. A Section 24 notice is a statutory notice of claim. Recording and enforcing a mechanics lien involve additional steps and deadlines. Owners should still treat the notice seriously because it can affect how remaining project funds must be handled.

What is the biggest mistake an owner can make after receiving the notice?

The biggest mistake is paying the GC after notice without retaining funds or getting legal advice. Once notice is received, the owner’s handling of remaining funds can materially affect lien exposure.

Practical Takeaway

For an Illinois owner who receives a $200,000 Section 24 notice on a project where the owner contracted with the GC for $300,000 and already paid the GC $200,000, the immediate focus should be the remaining $100,000 and the statutory payment trail.

If the owner properly obtained sworn statements and made the earlier $200,000 payment before any notice of the subcontractor’s claim, the owner may have defenses to paying beyond the unpaid contract balance. But if the owner paid after notice, ignored sworn statements showing the subcontractor’s claim, or failed to follow the statutory payment process, the owner may face increased lien risk.

The safest response is to freeze remaining payments, collect the sworn statements and lien waivers, verify the notice deadline, identify the claimant’s tier, and consult Illinois construction counsel immediately.
