A construction lien protects your right to payment when a project owner or general contractor fails to pay for work you performed. Filing one correctly requires hitting exact deadlines, preparing specific documents, and following your state's procedural rules to the letter. Miss a single step and the lien is void.

This guide walks through each stage of the construction lien process, from the preliminary notice you send before work begins to the lien release you file after collecting payment. Every step includes timeline benchmarks and practical examples so you can track your own filing process against real deadlines.

Step 1: Send a Preliminary Notice

The preliminary notice is your first move. It does not create a lien. It preserves your right to file one later.

Thirty-seven states require subcontractors and material suppliers to send a preliminary notice to the property owner within a specific window after first furnishing labor or materials. The window varies:

California: 20 days from first furnishing
Arizona: 20 days from first furnishing
Texas: 15th day of the 2nd month after work begins
Florida: 45 days from first furnishing (called "Notice to Owner")
Washington: 60 days from first furnishing
Nevada: 31 days from first furnishing

The notice must go to the property owner. Many states also require copies to the GC, the construction lender, and sometimes the original contractor. Delivery methods matter. California accepts certified mail or personal delivery. Texas requires certified mail with return receipt.

What to include in the preliminary notice:

Your company name and contact information
The property owner's name
The project address and legal description
A general description of the labor or materials you will furnish
The estimated total value of your work

Keep a copy of the notice and proof of delivery. Without proof that the notice was sent and received within the statutory window, your lien rights may not survive a challenge.

Step 2: Track Your Last Date of Work

Your lien filing deadline starts running from a specific triggering event. Identifying the correct trigger date is the most error-prone step in the entire process.

Common trigger dates by state:

Trigger Event	States Using This Trigger
Last day claimant furnished labor/materials	CA, FL, WA, NV, AZ, and 18 others
Completion of the project	GA, IL, OH, and 7 others
Substantial completion	TX (residential), NY (certain projects)
Owner acceptance or occupancy	PA, MD (certain project types)
Filing of a notice of completion	CA (shortens deadline from 90 to 30 days for subs)

The distinction between "last day you worked" and "project completion" can span months. A plumber who finishes in month 6 of a 14-month project faces a very different deadline depending on which trigger the state uses.

Track your last date of work with documentation: daily logs, delivery receipts, timesheets, and sign-off sheets. If the trigger is project completion, monitor the GC's progress and watch for notices of completion filed by the owner.

Step 3: Calculate Your Filing Deadline

Once you know your trigger date, calculate the statutory filing deadline. This is non-negotiable. Courts enforce these deadlines strictly.

State	Filing Deadline	Measured From
California	90 days (subs), 60 days (after notice of completion)	Last day of furnishing
Texas	15th day of 4th month (residential), 15th day of 3rd month (commercial, for subs)	Last day of work in that month
Florida	90 days	Last day of furnishing
New York	8 months	Last day of work
Georgia	90 days	Project completion
Illinois	4 months	Project completion
Ohio	75 days	Last day of furnishing
Pennsylvania	6 months	Last day of work
Colorado	4 months	Last day of furnishing
Michigan	90 days	Last day of furnishing

Use a lien deadline calculator to compute your exact deadline. Manual calculation errors account for 23% of invalid lien filings according to a 2024 National Association of Credit Management survey.

Step 4: Prepare the Lien Document

The lien document goes by different names depending on your state: Claim of Lien (Florida), Mechanic's Lien Affidavit (Georgia), Statement of Mechanic's Lien (Illinois), or Notice of Mechanic's Lien (California).

Regardless of the name, the document must include specific information. Omitting any required element makes the lien voidable.

Required elements in most states:

Claimant's full legal name and address
Property owner's name (as shown on title records)
Name of the party who hired the claimant (GC or higher-tier sub)
Legal description of the property (lot, block, subdivision, or metes and bounds)
Property street address
Description of the labor performed or materials furnished
Dates of first and last work
Total amount claimed (unpaid balance)
Notarization (required in approximately 30 states)
Verification under oath (required in approximately 20 states)

Common mistakes that invalidate liens:

Using the property street address instead of the legal description
Claiming more than the contract amount plus approved change orders (some states treat this as a fraudulent lien)
Naming the wrong property owner (check county records, not just the contract)
Failing to get the document notarized in states that require it

Step 5: Record the Lien with the County

File the lien document with the county recorder (or clerk of court) in the county where the property is located. This is a straightforward administrative process.

What to bring or submit:

The original signed and notarized lien document
A copy for your records
The filing fee (ranges from $15 to $150 depending on the county)
Some counties require a cover sheet or specific formatting

Most counties now accept electronic filing. Check your county recorder's website for online submission portals. Electronic filing provides same-day recording in most jurisdictions compared to 3-5 business days for mail submissions.

After recording, the county assigns a document number and records the filing date. Keep this information. You will need it for the enforcement phase and for the eventual lien release.

Step 6: Serve Notice of the Filed Lien

Recording the lien is not enough in most states. You must also notify the property owner that a lien has been filed.

Service requirements vary by state:

California: Serve a copy of the recorded lien on the owner within 15 days of recording
Florida: Serve a copy on the owner within 15 days of recording
Texas: No separate service requirement (the lien affidavit itself includes notice)
New York: Serve within 30 days of filing
Georgia: No separate service requirement

Acceptable service methods include certified mail with return receipt, personal service by a process server, or in some states, regular first-class mail. Document the service method and keep the proof.

Step 7: Enforce the Lien

A recorded construction lien does not automatically result in payment. You must enforce it by filing a foreclosure lawsuit within the statutory enforcement period.

Enforcement deadlines by state:

State	Enforcement Deadline	Measured From
California	90 days	Date lien was recorded
Texas	2 years	Date lien was filed or could have been filed
Florida	1 year	Date lien was recorded
New York	1 year	Date lien was filed
Georgia	1 year	Date lien was filed
Illinois	2 years	Project completion
Ohio	6 years	Date lien was filed
Pennsylvania	2 years	Date lien was filed

If you do not file suit within the enforcement window, the lien expires. Period. No court can revive an expired lien.

The foreclosure lawsuit asks the court to order the property sold to satisfy your claim. In practice, 78% of lien disputes settle before trial. The lien creates enough pressure on the property owner to motivate negotiation. Attorney fees for lien enforcement litigation average $8,000 to $25,000 depending on complexity.

Step 8: Release the Lien After Payment

Once you receive full payment, you must file a lien release (also called a satisfaction, discharge, or cancellation) with the county recorder.

Most states impose penalties for failing to release a satisfied lien:

California: Owner can recover $2,000 penalty plus actual damages
Texas: $10,000 penalty plus attorney fees
Florida: Claimant liable for actual damages plus attorney fees
New York: Court can impose sanctions and award damages

File the release promptly. A lingering lien after payment damages your reputation and exposes you to statutory penalties. The release document references the original lien's recording information and states that the lien is discharged.

Timeline Example: Florida Commercial Project

Here is a concrete timeline for a subcontractor filing a construction lien on a commercial project in Florida.

Day 1: Subcontractor begins work on-site
Day 40: Sub sends Notice to Owner (must be within 45 days of first furnishing)
Day 180: Sub completes all work
Day 200: Sub sends final invoice to GC
Day 230: No payment received. Sub decides to file lien.
Day 265: Sub records Claim of Lien with county (within 90 days of last furnishing)
Day 275: Sub serves copy of lien on property owner (within 15 days of recording)
Day 350: Sub files foreclosure lawsuit (within 1 year of recording)
Day 420: Parties reach settlement. GC pays outstanding balance.
Day 425: Sub files Satisfaction of Lien with county recorder.

Total elapsed time from first work to resolution: 14 months. This is typical for contested construction lien claims.

Frequently Asked Questions

Can I file a construction lien if I don't have a written contract? Yes, in most states. Mechanic lien rights are statutory and do not require a written contract. Oral agreements, purchase orders, and even implied contracts can support a valid lien. However, proving the terms of an oral agreement is more difficult, so written documentation of the scope and agreed price strengthens your claim significantly.

What if the property owner already sold the building? The lien follows the property. The new owner takes the property subject to the lien. The new owner can sue the seller for failure to disclose, but the lien remains valid and enforceable against the property regardless of ownership changes.

Can I file a construction lien for retainage? Yes. Retainage is earned but withheld compensation. It is lienable in all 50 states. Many subs wait to see if retainage is released before filing a lien. The filing deadline runs from your last day of work, not from when retainage was due. Do not wait too long.

What if the GC paid me partially? Can I lien for the remaining balance? Yes. File the lien for the unpaid balance only. Claiming more than the amount actually owed can expose you to penalties for filing a fraudulent or exaggerated lien in some states. Document all payments received and show the remaining unpaid balance clearly in the lien document.

Does filing a construction lien affect my credit? Filing a lien does not directly affect your credit score. However, if the owner or GC files a counterclaim and obtains a judgment against you (for example, for a wrongfully filed lien), that judgment could affect your credit.

Can I file a construction lien on a government project? No. Government property is immune from mechanic liens. On public projects, your remedy is a payment bond claim under the Miller Act (federal projects) or the applicable state Little Miller Act. The claim process, deadlines, and documentation requirements differ from the lien process.
