What Governs a Chicago Lien — and How the Filing Workflow Operates
A mechanics lien on a Chicago building is not a separate city statute — it is an Illinois Mechanics Lien Act lien (770 ILCS 60) on Cook County real estate. What makes Chicago filing distinct is the procedure and geography: which office records the Claim for Lien, how Cook County charges to record it, how the owner is identified for the 90-day notice when title sits in a land trust, and which court hears the foreclosure. The workflow is: (1) fix the claimant's last day of work or last delivery and determine whether the claimant is in a direct contract with the owner or is a sub-tier claimant; (2) if sub-tier, serve the 90-day Subcontractor and Material Notice on the owner under § 60/24 within 90 days; (3) record the verified Claim for Lien with the Cook County Clerk's Recordings Division within 4 months under § 60/7; and (4) if payment still does not come, file the foreclosure suit in the Circuit Court of Cook County within 2 years under § 60/9. Three Cook County realities shape every filing: the recording office changed (the Recorder of Deeds was consolidated into the Cook County Clerk's Office effective December 7, 2020); land-trust title is everywhere, hiding the true owner behind a trustee bank; and foreclosure is a Cook County Chancery matter heard at the Richard J. Daley Center.
Who Must File — and What Each Chicago Claimant Does
Illinois extends lien rights to essentially everyone in the construction payment chain who improves real property with the owner's authority — general contractors, subcontractors at every tier, material suppliers, and equipment lessors — but the steps differ by tier, and each claimant must protect its own lien. An original (general) contractor in a direct contract with the owner records its verified Claim for Lien with the Cook County Clerk's Recordings Division within 4 months of last work to preserve priority under § 60/7, and brings any foreclosure suit within 2 years under § 60/9; it does not serve the 90-day notice, but must be ready to furnish a sworn statement of its subcontractors and suppliers on the owner's demand under § 60/5. Every claimant not in privity with the owner — a subcontractor, supplier, or laborer — must serve the 90-day Subcontractor and Material Notice on the owner under § 60/24 within 90 days of last work, in addition to recording the Claim for Lien within 4 months and suing within 2 years. In Cook County the hard part is often identifying the owner to serve, because land-trust title hides the beneficiary behind a trustee bank.
Where and How to Record in Cook County
A Chicago Claim for Lien is recorded with the Cook County Clerk's Office, Recordings Division — the office that absorbed the former Cook County Recorder of Deeds on December 7, 2020. Recording is handled at 118 N. Clark Street in the Loop and through the Clerk's e-recording partners, which is how most commercial claimants and their attorneys file today. The document is recorded against the Cook County parcel where the Chicago property sits, using a legal description that matches the parcel — a street address alone is not a legal description, and a wrong or missing description is a frequent defect. Cook County records standard real-property documents under a flat, predictable recording fee rather than a per-page charge, so a typical Claim for Lien is recorded for a single standardized fee (roughly $90–$110 for a standard document; confirm the current amount with the Cook County Clerk's Recordings Division). The verified Claim for Lien must be recorded within 4 months of last work to keep priority over third parties under § 60/7; recording after 4 months but within 2 years still creates a lien, but only against the owner of record and parties with actual notice.
The Chicago Lien Deadlines & What the Act Requires
The verified Claim for Lien is recorded with the Cook County Clerk's Recordings Division within 4 months of last work to preserve priority (§ 60/7); a sub-tier claimant also serves the 90-day notice (§ 60/24) within 90 days of last work; and the foreclosure suit is filed in the Circuit Court of Cook County within 2 years of completion (§ 60/9). If the owner serves a Section 34 demand under § 60/34, the claimant must sue within 30 days or forfeit the lien. Required items in the Claim for Lien under § 60/7: the claimant's name; the owner and the party who ordered the work; a legal description of the Cook County property sufficient to identify it; the nature of the labor or material furnished; the contract or its substance and the dates of first and last work; and the balance due after allowing all credits, verified under oath. Every deadline is keyed to the claimant's last work or last furnishing — not the invoice date, a warranty call-back, or the overall project's completion by other trades. A Claim for Lien recorded after the 4-month window, recorded against the wrong parcel, or missing the § 60/7 content exposes the claimant to lost priority, an unenforceable lien, or a defensible defect.
The Owner's Position, the Sworn Statement & Section 34
A Chicago owner or developer manages lien risk with three Illinois tools. First, the sworn statement under § 60/5: before paying the general contractor, the owner can demand a sworn statement listing every subcontractor and supplier and the amounts owed, so the owner knows who might lien and can withhold accordingly — paying without it is how owners end up paying twice when a served sub records a lien. Second, the 90-day notice under § 60/24 tells the owner exactly which sub-tier claimants to protect against. Third, the Section 34 demand under § 60/34: an owner who wants to clear a recorded lien can serve a written demand that forces the claimant to file suit within 30 days or forfeit the lien. For the claimant, the mirror image applies: serve the 90-day notice on the correct owner — trustee and beneficiary where a land trust holds title — record a verified Claim for Lien that states the true balance due, and be ready to sue promptly if a Section 34 demand arrives. On the waiver side, a Chicago contractor or subcontractor should never sign an unconditional lien waiver before the corresponding payment has actually cleared.
Recording Fees and Where to Bring the Foreclosure
A Chicago lien has two cost centers. The first is small and up front: the Cook County Clerk's flat recording fee for the Claim for Lien (roughly $90–$110 for a standard document; confirm the current amount with the Recordings Division). There is no separate per-page charge under Cook County's predictable-fee approach, and no recording fee for the 90-day notice, which is served on the owner, not recorded. The second cost center is the foreclosure, and it applies only if payment still does not come. The suit is filed in the Circuit Court of Cook County, Chancery Division, at the Richard J. Daley Center, 50 W. Washington Street, within 2 years of completion under § 60/9. A foreclosure can result in a judicial sale of the property, with proceeds distributed by priority — which is why recording within the 4-month window to preserve priority matters so much. A contested lien or a full Cook County foreclosure runs into real attorney time, especially where land-trust title, competing lenders, or a Section 34 demand are in play.
Frequently Asked Questions
Where do you file a mechanics lien in Chicago?
You record a Chicago Claim for Lien with the Cook County Clerk's Office, Recordings Division — not a separate Recorder of Deeds. Illinois voters approved consolidating the Cook County Recorder of Deeds into the Cook County Clerk's Office, and that merger took effect on December 7, 2020, so the office that once recorded deeds and liens is now the Recordings Division of the Cook County Clerk. Recording is handled downtown at 118 N. Clark Street in the Loop and through the Clerk's e-recording partners. The property must sit in Cook County. Recording the verified Claim for Lien in the county where the property lies is what perfects the lien against third parties; a lien recorded in the wrong county, or merely served on the owner without recording, does not protect priority. The Illinois Mechanics Lien Act (770 ILCS 60) governs the content and timing of the Claim for Lien, and the Cook County Clerk's Recordings Division is where it is recorded.
What is the deadline to file a mechanics lien in Chicago?
There are two clocks under the Illinois Mechanics Lien Act, and both run from the claimant's last work or last furnishing — not the invoice date. First, to keep priority over third parties, the verified Claim for Lien must be recorded with the Cook County Clerk's Recordings Division within 4 months after completion under 770 ILCS 60/7. Recording after 4 months but within 2 years still creates a lien, but only against the owner of record at the time of recording and parties with actual notice — the claimant loses priority against bona fide purchasers and lenders. Second, the suit to foreclose the lien must be commenced within 2 years of completion under 770 ILCS 60/9, in the Circuit Court of Cook County. The safe practice for every claimant is to record within 4 months and file suit well within 2 years. A subcontractor or supplier must also serve the 90-day notice under 770 ILCS 60/24, and an owner can shorten the enforcement clock to 30 days by serving a Section 34 demand under 770 ILCS 60/34.
Do subcontractors have to send a 90-day notice in Chicago?
Yes. A subcontractor, sub-subcontractor, or material supplier that did not contract directly with the owner must serve the owner with the 90-day Subcontractor and Material Notice under 770 ILCS 60/24 within 90 days of its last work or last furnishing, or the sub-tier lien is lost — even if the Claim for Lien is later recorded on time. The notice tells the owner who the claimant is, what it furnished, and the amount claimed, and it lets the owner withhold that amount from the general contractor. On an owner-occupied single-family residence, the interaction with the 60-day notice and sworn-statement rules under 770 ILCS 60/5 and § 60/24 is stricter, and missing the residential notice can bar the lien entirely. Serving the 90-day notice is separate from and in addition to recording the Claim for Lien within 4 months: a Chicago sub or supplier must do both. In Cook County, identifying the correct owner to serve is complicated by the widespread use of Illinois land trusts, so the notice must reach the trustee and the beneficiary, not just the building or the operating tenant.
How much does it cost to record a mechanics lien in Cook County?
Cook County records standard real-property documents, including a Claim for Lien, under a flat, predictable recording fee rather than a per-page charge, so the recording cost for a typical mechanics lien is a single standardized fee (roughly $90–$110 for a standard document; confirm the current amount with the Cook County Clerk's Recordings Division before filing, because the fee schedule is updated periodically). That recording fee is small relative to the value the lien secures. The larger costs come later and only if the claim is contested: preparing the verified Claim for Lien so it satisfies 770 ILCS 60, serving the 90-day notice on the correct owner (including a land-trust trustee and beneficiary), and — if payment still does not come — filing and prosecuting a foreclosure suit in the Circuit Court of Cook County, Chancery Division. A straightforward Chicago Claim for Lien can be prepared and recorded inexpensively; a contested lien or a full foreclosure runs into attorney time.
What must a Chicago Claim for Lien contain?
A Chicago Claim for Lien is a verified (sworn) statement recorded under the Illinois Mechanics Lien Act, and it must identify the claimant, the owner and the party who ordered the work, a legal description of the Cook County property sufficient to identify it, the nature of the labor or material furnished, the contract or the substance of it, the dates work began and was last performed or material was last furnished, and the balance due after allowing all credits. The claimant verifies the statement under oath. Accuracy matters: the amount must reflect the true unpaid balance, the property description must match the Cook County parcel (an incorrect or missing legal description is a frequent defect), and the dates must support a recording within the 4-month window under 770 ILCS 60/7. Because the document is verified and creates a cloud on Cook County title, an inflated or knowingly false claim exposes the claimant to defenses and, in some cases, liability — so the Claim for Lien should state the real balance due, tied to the contract and the last date of work.
Where do you foreclose a mechanics lien in Chicago?
A Chicago mechanics lien is foreclosed by filing a complaint in the Circuit Court of Cook County — the Chancery Division at the Richard J. Daley Center, 50 W. Washington Street, hears mechanics lien foreclosures for Cook County property. The suit must be brought within 2 years of completion under 770 ILCS 60/9. Recording the Claim for Lien within 4 months preserves the lien and its priority, but recording alone does not collect the money; the lien is enforced by the foreclosure action, which can result in a judicial sale of the property to satisfy the unpaid balance, with the proceeds distributed by priority. An owner or general contractor who wants to force the issue can serve a Section 34 demand under 770 ILCS 60/34, which requires the claimant to file the foreclosure suit within 30 days of the demand or forfeit the lien — so a Chicago claimant who receives a Section 34 demand must be ready to sue immediately, well inside the ordinary 2-year window.
How do Illinois land trusts affect filing a lien in Chicago?
Cook County uses Illinois land trusts more than almost anywhere in the country, and that changes how a Chicago claimant identifies the owner. In a land trust, legal title sits with a trustee — typically a bank or trust company — while the real party in interest is the beneficiary, whose identity is not on the recorded title. For a general contractor recording a Claim for Lien this mostly affects the property and owner description; for a subcontractor or supplier serving the 90-day notice under 770 ILCS 60/24 it is decisive, because a notice served only on the building, the tenant, or the apparent operator — rather than the trustee and the beneficiary — can be insufficient to perfect the sub-tier lien. Before serving the 90-day notice on a downtown Chicago or Cook County project, a claimant should confirm whether land-trust title applies and identify both the trustee of record and the beneficiary. This land-trust step is one of the most common reasons a technically timely Cook County sub-tier lien still fails.
