Getting paid on a construction job requires more than finishing the work — it requires a documented payment chain that starts before you drive the first nail. Subcontractors, material suppliers, and lower-tier subs who fail to serve a preliminary notice (required in most states within 20 days of first furnishing labor or materials) forfeit their right to file a mechanics lien if payment is refused. A mechanics lien is a legal claim against the property itself, giving you leverage that an unpaid invoice alone does not. According to Rabbet's 2024 Construction Payments Report, 82% of contractors wait more than 30 days for payment — up from 49% just two years earlier. The contractors who consistently get paid are not the ones who work the hardest. They are the ones who protect their payment rights from day one.
What Steps Do Subcontractors Need to Take to Get Paid on a Construction Job?
Getting paid on a construction job follows a predictable sequence: sign a clear contract, serve a preliminary notice before or immediately after starting work, submit invoices on schedule, and escalate through demand letters and mechanics liens if payment stalls. Skipping any step in that chain weakens your position. Miss the preliminary notice deadline and you may have no legal remedy at all — regardless of how solid your contract is.
Here is the full sequence broken down:
- Execute a written contract before mobilizing to the job site.
- Serve a preliminary notice within the state-required window (typically 20 days from first furnishing in California, Arizona, Nevada, Washington, and Oregon; Florida requires a Notice to Owner before or during the first 45 days of furnishing, under Fla. Stat. § 713.06(2)(c)).
- Submit pay applications or invoices on the contractually agreed schedule.
- Send a payment demand letter if payment is late — in writing, with a deadline.
- File a mechanics lien if the demand goes unanswered within the statutory cure period.
- Enforce the lien through litigation or negotiate a settlement before the lien enforcement deadline expires.
Each step builds on the one before it. The preliminary notice is the foundation. Without it, steps 5 and 6 are unavailable to you.
Why Do Preliminary Notices Matter for Construction Payment Collection?
A preliminary notice is the legal trigger that preserves your right to file a mechanics lien on a private construction project. Most states require it from any party who is not in direct contract with the property owner — meaning nearly every subcontractor, supplier, and lower-tier sub needs to file one.
State-by-state breakdown of preliminary notice windows:
| State | Notice Name | Deadline |
|---|---|---|
| California | 20-Day Preliminary Notice | 20 days from first furnishing (Cal. Civ. Code § 8200) |
| Florida | Notice to Owner | Before or during first 45 days of furnishing (Fla. Stat. § 713.06) |
| Arizona | 20-Day Preliminary Notice | 20 days from first furnishing (A.R.S. § 33-992.01) |
| Nevada | Notice of Right to Lien | Before or within 31 days of first furnishing (NRS § 108.245) |
| Washington | Notice of Right to Claim Lien | 60 days from first furnishing (RCW § 60.04.031) |
| Oregon | Notice of Right to a Lien | 8 days from first furnishing (ORS § 87.021) |
Late service does not always eliminate your rights entirely. In California, for example, a late preliminary notice limits lien protection to work performed in the 20 days before service — but it does not protect work furnished before that window. In Florida, failing to serve a Notice to Owner at all is a complete bar to lien rights under Fla. Stat. § 713.06(2)(c).
The math is simple. In 2024, preliminary notices were filed on construction projects valued at over $22.7 billion in the United States, according to data cited by DocJoist's 2026 Construction Payment Statistics. That volume reflects an industry that increasingly understands: the notice is not optional paperwork — it is payment protection.
How Do Contractors Get Paid When the GC or Owner Goes Silent?
When calls stop getting returned and invoices stop getting paid, the escalation path is: written demand, mechanics lien, enforcement. Do not wait. Every state has a deadline by which a mechanics lien must be filed after a project reaches substantial completion or after your last date of furnishing. Miss that deadline and the right to lien expires permanently.
Step 1 — Written payment demand. Send a formal demand letter via certified mail. State the amount owed, the contractual basis for payment, and a firm deadline (10 to 14 days is standard). Keep a copy and your certificate of mailing.
Step 2 — File a mechanics lien. If the deadline passes without payment, file the lien immediately. A mechanics lien is recorded in the county where the property is located. It clouds the title, which means the owner cannot refinance or sell without resolving the lien. That is your leverage.
Step 3 — Enforce or negotiate. A filed lien does not automatically result in payment — you must either enforce it through a lawsuit before the enforcement deadline or negotiate a settlement. Most mechanics liens settle without going to court because the owner has strong financial incentive to clear the title.
Slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending, according to Rabbet's 2024 Construction Payments Report. That cost does not fall equally. It falls hardest on subcontractors who have no lien rights to exercise.
What Should a Construction Payment Demand Letter Include?
A construction payment demand letter should include the project name and address, the contract date, the amount owed with an itemized breakdown, the date payment became due, and a specific deadline for response. Write it plainly. You are documenting the debt and your intent to enforce it — not negotiating.
Required elements:
- Your company name and license number
- Project address and owner's name
- GC name and address (send to both)
- Invoice numbers and total amount due
- Contract or subcontract reference
- Statement of your lien rights — "If payment is not received by [date], I reserve the right to file a mechanics lien against this property."
- Deadline — 10 to 14 days from the date of the letter
Send it via USPS Certified Mail so you have a paper trail. USPS Certified Mail costs $4.85 as the base service fee in 2026 (plus standard First-Class postage), per USPS Notice 123. That $4.85 receipt could be the document that proves you made a proper demand if the dispute goes to court or arbitration.
How Do You File a Mechanics Lien to Collect a Construction Debt?
To file a mechanics lien, you prepare a lien claim document containing specific information required by your state's statute, have it notarized (required in most states), and record it with the county recorder or clerk's office in the county where the project is located. Filing fees vary by county but are typically $10–$50.
The lien claim must generally include:
- Claimant's name and address
- Property owner's name and address
- Property legal description (not just the street address — the legal description from county records)
- Amount claimed, with a general description of labor or materials furnished
- First and last date of furnishing
- Statement that the amount is due and unpaid
After recording, most states require you to serve a copy of the filed lien on the property owner within a set window — California requires service within 15 days of recording under Cal. Civ. Code § 8416. Missing the service requirement can invalidate an otherwise properly filed lien.
Enforcement deadlines vary significantly: California requires a lien foreclosure action within 90 days of filing (Cal. Civ. Code § 8460); Florida requires enforcement within one year of the lien's recording under Fla. Stat. § 713.22. Know your state's deadline before you file.
What Are the Common Ways Subcontractors Protect Payment Rights Before a Problem Starts?
The subcontractors who rarely have collection problems are the ones who treat payment protection as part of every job setup — not a reaction to getting stiffed. The most effective protective measures cost almost nothing relative to what they protect.
Get everything in writing. Every subcontract should specify the payment schedule, the pay application process, retainage percentage, and the dispute resolution clause. Verbal agreements are nearly impossible to enforce.
Serve preliminary notices on every job, every time. Not just on jobs where the GC seems sketchy. Slow-paying GCs rarely announce themselves in advance. According to NetSuite's 2025 construction payment management research, 75% of subcontractors report frequently floating payments while awaiting disbursements — meaning most subcontractors are already absorbing cash flow losses before they ever realize a job is headed toward non-payment.
Track your first furnishing date obsessively. The preliminary notice deadline in most states is calculated from the date you first provided labor or materials. If you are fuzzy on that date, you are vulnerable.
Maintain documentation of completed work. Signed delivery receipts, daily logs, photos with timestamps, and approved change orders are your evidence if a payment dispute becomes a legal dispute.
Understand your contract's pay-if-paid vs. pay-when-paid clause. These are not the same thing. A pay-if-paid clause, enforceable in some states, conditions your right to payment on whether the GC first gets paid by the owner. If you signed one without knowing it, your lien rights may be your only remedy.
How Does the Size of a Subcontract Affect Whether Lien Rights Are Worth Protecting?
Lien rights are worth protecting on every subcontract, regardless of size — because the cost of preserving them is fixed and small, while the exposure from losing them scales with the contract value. A single preliminary notice through LienFlash costs $24.99. If that notice preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, the return on that filing cost exceeds 60,000%. On a $75,000 contract, it exceeds 300,000%.
The practical argument for always filing: you cannot predict which jobs will pay late. The average days sales outstanding (DSO) in construction is approximately 90 days — double the 45-day threshold that financial experts consider healthy, according to Rabbet's 2024 Construction Payments Report via For Construction Pros. A DSO of 90 days means that even on a "normal" job, you are effectively financing the owner's construction costs for three months. A preliminary notice does not shorten payment terms by itself — but it means that if payment does not come, you have a remedy.
Frequently Asked Questions
What is the fastest way to get paid on a construction job?
The fastest path to payment is a signed contract with clear payment terms, a properly served preliminary notice filed before or immediately after first furnishing, and consistent pay application submissions on the contractual schedule. Owners and GCs prioritize subcontractors who have documented their lien rights — because those subs have the most enforceable claim if payment disputes arise.
Do I need a lawyer to file a mechanics lien?
No. In most states, a subcontractor can prepare, notarize, and record a mechanics lien without an attorney. However, the lien document must meet exact statutory requirements — incorrect property descriptions, missing information, or late filing can void the lien entirely. Using attorney-reviewed templates substantially reduces that risk. Enforcement of a lien (suing to foreclose) typically does require an attorney.
What happens if I miss the preliminary notice deadline?
The consequence depends on your state. In California, late service limits lien protection to work performed in the 20 days before service — all prior work is unprotected. In Florida, failure to serve a Notice to Owner at all is a complete bar to mechanics lien rights on private projects under Fla. Stat. § 713.06(2)(c). In Oregon, where the window is just 8 days from first furnishing, missing the deadline is almost always fatal to lien rights. The safest approach is to treat the preliminary notice as part of your job startup checklist, filed the same day you mobilize.
Can I file a mechanics lien on a public construction project?
No. Mechanics liens cannot be filed against government-owned property. On public projects, the payment protection mechanism is a payment bond claim under the federal Miller Act (40 U.S.C. § 3131) for federal jobs, or the applicable state Little Miller Act for state and local public works. The deadlines and notice requirements for bond claims differ significantly from lien law — verify the rules for your state before assuming the same procedures apply.
How long does a mechanics lien stay on a property?
The duration varies by state. In California, a mechanics lien expires 90 days after recording unless a foreclosure lawsuit is filed (Cal. Civ. Code § 8460). In Florida, a lien is enforceable for one year from the recording date under Fla. Stat. § 713.22. If you file a lien but do not enforce it within the statutory window, the lien expires and your leverage disappears — often without the owner needing to do anything.
What is the difference between a pay-when-paid and pay-if-paid clause?
A pay-when-paid clause sets timing — it means the GC will pay you when they receive payment from the owner, typically within a reasonable time. Courts generally treat this as a timing provision, not a risk transfer. A pay-if-paid clause is a risk transfer — it conditions your right to payment on the GC receiving payment from the owner. If the owner never pays the GC, you may not be entitled to payment at all. Pay-if-paid clauses are enforceable in some states but prohibited or narrowly construed in others. Read every subcontract before signing.
Can I file a lien if I only supplied materials and never performed labor on site?
Yes. Material suppliers have mechanics lien rights in every state that recognizes mechanics liens, provided they properly served a preliminary notice within the required window. The same deadlines and requirements that apply to subcontractors performing labor apply to suppliers furnishing materials. Your first furnishing date — the date materials were first delivered to the job site — starts the preliminary notice clock.
What if the general contractor files bankruptcy before I get paid?
A mechanics lien recorded before the GC's bankruptcy filing may survive, depending on whether the lien attached to the property before the bankruptcy petition date — but lien law and bankruptcy law intersect in complex ways. A payment bond claim may be your more reliable remedy if a bond exists on the project. Consult an attorney immediately when you learn a GC or owner has filed for bankruptcy, because deadlines for creditor claims in bankruptcy are strict and unforgiving.
