Filing a Mechanic Lien with the Cook County Recorder

To record a mechanic lien in Cook County, you will need:
- The property's legal description (available from the Cook County Assessor by PIN or address)

- A description of the labor or materials furnished
- The contract amount and unpaid balance
- The dates of first and last furnishing

Common Cook County Construction Projects
Payment disputes arise across every sector of Cook County construction. Your remedy depends on the project type and your role.
Suburban Commercial Development
Office parks, retail centers, and mixed-use developments across suburban Cook County — Schaumburg, Oak Brook, Des Plaines, Skokie — generate frequent payment disputes between general contractors, specialty subcontractors, and material suppliers.
Residential Subdivision and Custom Homes
Single-family home construction and subdivision development throughout the Cook County suburbs involve framing, plumbing, electrical, and finish carpentry subcontractors who may need to file mechanic liens when payment stalls.
Industrial and Warehouse Construction
The industrial corridors of southern and western Cook County — Elk Grove Village, Bedford Park, McCook — see large-scale warehouse, distribution center, and manufacturing facility projects where subcontractor payment disputes are common.
School District and Municipal Projects
Cook County is home to dozens of school districts and municipalities that fund construction projects. These are public projects requiring payment bond claims or liens on public funds instead of mechanic liens.
Land Trusts, LLCs, and Ownership Identification in Cook County
Cook County has one of the highest concentrations of land trust ownership in Illinois. Many commercial and investment properties are held in Illinois land trusts where a bank or trust company serves as the nominal titleholder. Residential properties may be held in LLCs, family trusts, or estate names. Identifying the correct owner is essential for valid mechanic lien filing and proper service of the Section 24 notice.
Our firm conducts thorough ownership research through Cook County property records, corporate filings with the Illinois Secretary of State, and title searches to identify all parties who should receive notice. This step is frequently overlooked by contractors who attempt to file liens on their own — and errors in owner identification can invalidate the entire lien claim.

Frequently Asked Questions — Cook County Mechanic Liens
Mechanic liens for all Cook County properties — including Chicago and suburban municipalities — are recorded with the Cook County Recorder of Deeds at 118 N. Clark Street, Chicago, IL 60602. Electronic recording is also available through approved vendors. The lien must include the property's legal description, which can be obtained from the Cook County Assessor using the property's PIN.
The statutory requirements under 770 ILCS 60 are the same throughout Cook County. Both Chicago and suburban Cook County properties use the Cook County Recorder. The differences are practical — identifying the property owner may involve different township assessor records, and municipal permitting requirements vary by suburb.
The Cook County Assessor's website allows you to search by address or PIN to find the property's legal description. You can also obtain it from the title company, the prior deed of record, or a survey of the property. The legal description is required for both the lien claim and the recording.
Land trusts are common in Cook County. If the property is held in a land trust, the mechanic lien should name both the trustee (the bank or trust company) and the beneficial owner if known. Serving the Section 24 notice on the correct party is critical — serving only the trustee when the beneficial owner is known can create complications.
Prevailing wage requirements under the Illinois Prevailing Wage Act apply to public projects but do not directly affect your mechanic lien rights on private projects. However, prevailing wage violations on public projects can create additional claims and defenses that interact with bond claims and public fund liens.
Yes, if you performed work that benefits only a specific unit (such as interior renovation), the lien attaches to that unit. If the work benefits the common elements of the condominium association, the lien may need to be filed against the association or common elements, depending on who authorized the work.
Missing the 90-day Section 24 notice deadline forfeits your mechanic lien rights entirely. You may still have other remedies — such as a breach of contract claim against the party who hired you, a claim under the Trust Fund Act, or a demand letter — but the lien itself is lost. This makes tracking the notice deadline critical from the first day of furnishing.
A project is public if it is owned by a government entity — a municipality, school district, park district, county agency, or state body. The key question is who owns the real property where the work is performed. If the property owner is a public body, mechanic liens do not apply and you must pursue bond claims or liens on public funds instead.
