First-Tier Subs, Sub-Subcontractors & Specialty Trade Contractors
Illinois Mechanic Lien Rights for Subcontractors
Subcontractors perform the work that builds Illinois — but they are often the last to get paid. Understanding Section 24 notice requirements, lien amount limitations, and the difference between private and public project remedies is essential to protecting your right to payment.
How Subcontractors Get Paid in Illinois Construction
Subcontractors — whether first-tier subs contracting directly with the general contractor, or sub-subcontractors working under another subcontractor — are the backbone of every construction project. Electricians, plumbers, HVAC installers, framers, drywallers, painters, concrete finishers, ironworkers, and dozens of other specialty trades perform the actual construction work while relying on the payment chain above them to flow funds downward.
The typical payment flow runs from the property owner to the general contractor to the first-tier subcontractor and, where applicable, to the sub-subcontractor. At each level, retainage is withheld, pay applications are reviewed and sometimes reduced, and delays compound. A subcontractor may complete its scope of work months before receiving final payment — if payment comes at all.
Illinois law recognizes this vulnerability and gives subcontractors mechanic lien rights under 770 ILCS 60. But those rights come with strict conditions — most importantly, the Section 24 notice requirement that must be met within 90 days of first furnishing labor or material.
Common Payment Disputes Facing Subcontractors
Retainage Withholding Beyond Completion
General contractors routinely hold 5-10% retainage and delay release for months after the subcontractor's scope is complete, citing unfinished punch list items by other trades, project-wide substantial completion delays, or disputes with the owner that have nothing to do with the subcontractor's work.
Pay-If-Paid and Pay-When-Paid Clauses
Many subcontracts include 'pay-if-paid' or 'pay-when-paid' clauses that condition the GC's payment obligation on receipt of payment from the owner. Illinois courts distinguish between these clauses, with 'pay-if-paid' creating a condition precedent that may excuse the GC entirely if the owner does not pay.
Backcharge Disputes
GCs frequently assert backcharges — deductions for alleged deficiencies, cleanup costs, schedule delays, or damage attributed to the subcontractor. These backcharges often appear for the first time when the subcontractor demands payment, creating a dispute that must be resolved before the lien deadline expires.
GC Insolvency and Project Abandonment
When a general contractor goes bankrupt or abandons a project, all subcontractors below lose their contractual payment path. The mechanic lien becomes the subcontractor's most valuable asset — a direct claim against the property that survives the GC's insolvency and gives the subcontractor leverage to recover from the owner.
Private Project Remedies: Mechanic Liens for Subcontractors
On private construction projects, the mechanic lien is the subcontractor's primary payment remedy. Under the Illinois Mechanic Lien Act, any subcontractor who furnishes labor or material for an improvement to real property can claim a lien on the property — but only if the statutory notice and filing requirements are met.
Section 24 Notice (90-day deadline): Because subcontractors do not have a direct contract with the property owner, they must serve a Section 24 notice on the owner within 90 days of first furnishing labor or material. This notice informs the owner that the subcontractor is performing work and may claim a lien. Failure to serve this notice within 90 days completely forfeits the subcontractor's mechanic lien rights.
Section 24.1 Residential Notice (60-day deadline): On residential projects (owner-occupied, four or fewer units), subcontractors must serve an additional notice under Section 24.1 within 60 days of first furnishing. This notice has specific content requirements warning the homeowner about potential lien claims.
Lien Amount Limitations (770 ILCS 60/22): A subcontractor's lien amount is capped at the lesser of (a) the amount owed to the subcontractor, or (b) the amount the owner owes the general contractor at the time the owner receives the Section 24 notice. This "trap" means that if the owner has paid the GC most of the contract price before receiving your notice, your lien may be worth significantly less than what you are owed.
The lien must be recorded within four months of the subcontractor's last furnishing date. See our Illinois mechanic lien deadlines page for the complete timeline.
Public Project Remedies: Bond Claims for Subcontractors
On public construction projects — schools, government buildings, highways, municipal infrastructure — mechanic liens are unavailable because you cannot lien public property. Instead, subcontractors must pursue a payment bond claim against the surety bond the general contractor was required to post.
First-tier subcontractors (those with a direct contract with the GC/bond principal) typically have broader bond claim rights and longer notice deadlines than sub-subcontractors. Sub-subcontractors — those working under a first-tier sub — must usually provide written notice of their claim to the bond principal within a specified period, which varies depending on whether the project is governed by Illinois law (30 ILCS 550), a local bond ordinance, or the federal Miller Act.
When a public project does not have a payment bond, or when the bond is insufficient to cover all claims, subcontractors can pursue a lien on public funds under 770 ILCS 60/23. This remedy attaches to the contract proceeds the public body still owes the general contractor and has its own notice requirements.
Collection and Enforcement Options for Subcontractors
Subcontractors can pursue multiple collection strategies simultaneously, depending on the circumstances:
- Mechanic lien recording and foreclosure lawsuit to enforce the lien against the property
- Breach of subcontract claims against the general contractor for unpaid contract balances and retainage
- Illinois Trust Fund Act claims (770 ILCS 60/21.02) when the GC diverts owner payments instead of paying subs
- Prompt Payment Act claims for statutory interest and attorney fees on late payments
- Demand letters under Section 34, which can trigger a 30-day enforcement window against the lien claimant
- Unjust enrichment claims when the property owner benefited from the subcontractor's work without paying
- Personal guaranty enforcement if the GC's principals signed personal guaranties in the subcontract

Documentation Issues for Subcontractors
Subcontractors must maintain careful records to preserve their payment rights. Key documentation includes:
First furnishing date: The 90-day Section 24 notice deadline runs from the subcontractor's first furnishing of labor or material. This is not the contract date or the mobilization date — it is the date you first performed physical work or delivered materials to the project site. Track this date precisely for every project.
Sworn statement participation: The general contractor must provide the owner with a sworn statement listing all subcontractors and the amounts owed. Review any sworn statements that include your company's name to ensure the amounts are accurate. Inaccurate sworn statements can create disputes about the amount owed and potentially limit your lien.
Lien waiver management: Be cautious about signing unconditional lien waivers before receiving payment. An unconditional waiver releases your lien rights regardless of whether the check clears. Use conditional waivers whenever possible — they release your rights only upon actual receipt of payment.
Change order documentation: Disputed change orders are a leading cause of subcontractor payment disputes. Document every change order request in writing, including the scope of additional work, the agreed price, and authorization from the GC. Verbal approvals should be confirmed in writing immediately.
Why Subcontractors Hire Emalfarb Law
Subcontractors are the most common clients in our construction law practice because they face the highest volume of payment disputes and the most complex notice requirements. Unlike general contractors who lien the property directly, subcontractors must navigate the Section 24 notice process, the lien amount limitations of Section 22, the sworn statement system, and the distinction between private and public project remedies.
We help subcontractors across every trade — electrical, plumbing, HVAC, carpentry, concrete, steel erection, roofing, painting, flooring, landscaping, demolition, and specialty trades — protect and enforce their payment rights. Our approach combines proactive notice compliance (ensuring Section 24 notices go out on every project within the first week of work) with aggressive enforcement when payment is withheld.
When a subcontractor comes to us with a payment dispute, we immediately assess whether the Section 24 notice was timely, calculate the lien amount limitations under Section 22, and determine whether the project is private (lien) or public (bond claim). We then pursue the combination of remedies that maximizes recovery.
