A mechanics lien can include the reasonable value of labor performed, materials furnished, equipment rented, and services rendered that directly contributed to the improvement of real property—but the exact scope of lienable costs varies by state statute, and overstating your lien amount can void the entire claim. Core lienable items recognized across most states include unpaid contract amounts, approved change orders, retainage withheld, and mobilization costs. Items that are almost universally excluded include consequential damages, unabsorbed home-office overhead not tied to direct project costs, attorney fees (unless a specific fee-shifting statute applies), and lost profits on work that was never performed. Because overstatement penalties are severe in states like California and Florida, building your lien amount on documented, lienable costs is not optional—it is the difference between a valid claim and a void one.
What Core Costs Can You Always Include in a Mechanics Lien?
The baseline lienable amount in every U.S. jurisdiction is the unpaid value of labor, materials, and services actually furnished to the project. If you performed electrical rough-in, hung drywall, installed HVAC equipment, or supplied roofing materials that ended up on the job, that work is the foundation of your lien claim.
Across the four states where LienFlash operates, the statutes define lienable work as follows:
- California: Cal. Civ. Code § 8400 gives a direct contractor or claimant a lien for "the work provided" at the contract price or, if no price is set, the reasonable value of the work.
- Florida: Fla. Stat. § 713.05 and § 713.06 entitle lienors to a lien for the "contract price" of labor, services, or materials furnished in accordance with their contract.
- Texas: Tex. Prop. Code § 53.021 grants a lien for labor, specially fabricated materials, and materials furnished to the project.
- Washington: RCW 60.04.021 provides a lien for "the contract price" or, if no price is established, the reasonable value of the labor, professional services, materials, or equipment furnished.
Document everything. Time sheets, delivery receipts, approved submittals, and purchase orders are what turn a number on a lien form into a defensible claim.
Can You Include Retainage in a Mechanics Lien Claim?
Yes—retainage is a lienable debt. Retainage is money you earned. The GC or owner is simply holding it. When they refuse to release it at the end of the job, it becomes an unpaid amount subject to lien.
- California: Cal. Civ. Code § 8400 does not carve out retainage as non-lienable. Retainage owed under the contract is part of the contract price and is includable.
- Florida: Fla. Stat. § 713.001(17) defines the "lien amount" to include amounts owed under the contract, which expressly encompasses withheld retainage.
- Texas: Tex. Prop. Code § 53.021 includes amounts owed for labor and materials furnished, which courts in Texas have interpreted to include retainage balances.
- Washington: RCW 60.04.021 includes the contract price as the lien base, which encompasses retention withheld by the GC.
Track your retainage balance on every pay application and include it explicitly in your lien amount when you file. Leaving it out is leaving money on the table.
Can You Lien for Unpaid Change Orders and Extras?
Approved change orders are lienable. Work you performed under a written change order, or under a verbal direction you can document, is part of the contract price and belongs in your lien amount.
The trickier situation is unsigned or disputed change orders. Courts generally look at whether the extra work was actually performed and whether the owner or GC had knowledge of and acquiesced to it. An owner who watches your crew pour an extra foundation wall and says nothing has likely acquiesced—but that is a fact-specific legal question that varies by jurisdiction and by the specific contract language.
Practically speaking:
- Include approved, signed change orders in your lien without hesitation. They are as solid as the base contract.
- Include disputed change orders with care. You can include them if you have documentation showing the work was performed and directed. Be precise about the amount—overstatement is the risk.
- Verbal extras are harder but not impossible. Field emails, text messages, superintendent daily logs, and your own jobsite photos establishing the scope of extra work all support the claim.
If your contract contains a "no damages for delay" clause or a written change order requirement, consult a construction attorney in your state before including delay-related extras in your lien amount.
Are Overhead Costs Recoverable in a Mechanics Lien?
Job-site overhead directly tied to the project is generally lienable. Home-office overhead that would exist whether or not this project existed is generally not.
The line matters because mechanics lien statutes are tied to the value of work furnished to the improvement, not to your total cost of running a business. Examples of typically lienable overhead include:
- Job-site trailer costs and temporary utilities you paid for on this specific project
- Mobilization and demobilization expenses
- Project-specific insurance riders
- Project manager time billed to the job
Examples of overhead that most states will not support in a lien:
- Unabsorbed corporate overhead (the Eichleay formula calculation used in federal delay claims does not translate to mechanics liens in most states)
- General and administrative expenses not allocated to the specific project
- Marketing or estimating costs for this or other projects
California courts have been particularly strict on this distinction. If you include overhead in your lien, document it as a project-specific cost, not a general business expense.
Can You Include Rental Equipment Charges in a Lien Amount?
Equipment furnished to a project—including rented equipment—is lienable in most states when it was actually used on the project improvement.
- California: Cal. Civ. Code § 8400 expressly includes equipment in the definition of work that supports a lien.
- Florida: Fla. Stat. § 713.01(19) defines "labor, services, or materials" to include the rental value of equipment used in construction.
- Texas: Tex. Prop. Code § 53.021(a)(2) includes "specially fabricated materials" and by case law and subsequent statute covers equipment furnished for the project.
- Washington: RCW 60.04.011(9) defines "furnishing labor, professional services, materials, or equipment" to include equipment rentals.
If you are an equipment lessor—not the subcontractor but the company renting the crane or the scaffolding—you may have independent lien rights, but you will almost certainly need to serve a preliminary notice to preserve them. Check the notice requirements in your state before the equipment hits the site.
Can You Lien for Lost Profits on a Construction Project?
In most states, no—you cannot lien for profits on work you never performed. A mechanics lien secures the value of what you actually furnished to the improvement. It is not a vehicle for breach-of-contract damages, anticipatory profit, or consequential losses.
If you were wrongfully terminated mid-project and are owed profit on the remaining scope, your remedy is a breach-of-contract lawsuit, not a mechanics lien. The lien amount should reflect only the value of work performed through the date of termination.
There is a narrow exception worth knowing: if your contract was terminated and you had materials specially fabricated for the project that cannot be reused or resold—custom millwork, custom-fabricated steel, etc.—some states allow you to lien for the value of those materials even if they were never installed. Texas Prop. Code § 53.021(a)(2) expressly recognizes specially fabricated materials as lienable even if not delivered.
Are Attorney Fees Claimable in a Mechanics Lien Filing?
Attorney fees are generally not part of the lienable amount itself, but several states have fee-shifting statutes that allow a prevailing lien claimant to recover attorney fees through litigation—distinct from the lien filing amount.
- California: Cal. Civ. Code § 8488 allows the court discretion to award reasonable attorney fees to the prevailing party in a lien foreclosure action.
- Florida: Fla. Stat. § 713.29 provides for attorney fees to the prevailing party in an action to enforce a lien or to contest a lien.
- Texas: Tex. Prop. Code § 53.156 allows a court to award reasonable attorney fees in a lien foreclosure suit, in the court's discretion.
- Washington: RCW 60.04.181 authorizes the court to award reasonable attorney fees and costs to the prevailing party in a lien foreclosure action.
Do not include attorney fees in the dollar amount stated on your lien. That creates an overstatement, which can give the owner grounds to challenge the lien's validity. Attorney fees are a remedy you pursue if the lien goes to litigation—not a line item on the lien face.
What Costs Are Excluded From a Mechanics Lien?
Knowing what to leave out is just as important as knowing what to include—because overstating a lien can invalidate it entirely.
Costs that are almost universally excluded:
- Lost profits on unperformed work — work you were going to do but didn't
- Consequential damages — lost business opportunities, idle equipment caused by another trade's delay
- Punitive damages — not available through lien law
- Attorney fees — not a lienable cost (see above); recover through litigation if applicable
- Unabsorbed home-office overhead — indirect general business costs
- Interest — interest may be recoverable in a lien foreclosure lawsuit in some states, but it is generally not included in the face amount of the lien itself
- Penalties and liquidated damages the owner assessed against you — you cannot offset these into a higher lien amount
California's overstatement rule under Cal. Civ. Code § 8422 is one of the sharpest in the country: a lien that is "wilfully exaggerated" is void. Florida courts apply similar scrutiny. Texas Prop. Code § 53.026 addresses frivolous liens. The practical rule is simple: if you cannot point to a document—an invoice, a time sheet, a delivery ticket, an approved change order—do not include it.
According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. The mechanics lien is one of the most powerful tools you have to force payment—but only if the lien is valid. A lien thrown out on overstatement grounds leaves you with an unsecured claim in line with every other creditor.
How Do Preliminary Notices Affect What You Can Lien For?
Preliminary notice requirements do not change what costs are lienable—they determine whether you have lien rights at all.
In California, failure to serve a 20-day preliminary notice under Cal. Civ. Code § 8200 bars lien rights entirely on private works (with the exception of direct contractors). In Florida, a subcontractor who skips the Notice to Owner under Fla. Stat. § 713.06 loses lien rights. In Washington, failure to serve the Notice of Right to Claim Lien under RCW 60.04.031 eliminates lien rights.
If you did not serve the required preliminary notice, the question of what to include in your lien becomes academic—because you may not have a lien to file.

Frequently Asked Questions
Can I include mobilization costs in a mechanics lien?
Yes, in most states. Mobilization costs are direct project costs tied to furnishing labor and equipment to the specific improvement. Document them separately in your job cost records. General setup costs that would apply to any job are harder to defend; project-specific mobilization—moving equipment, setting up site facilities, initial material staging—is generally includable.
Can I lien for materials I purchased but never installed because the project was shut down?
It depends on whether the materials were specially fabricated for the project or are standard stock you can resell. Texas expressly allows liens for specially fabricated materials under Tex. Prop. Code § 53.021(a)(2) even if not delivered. For standard resalable materials, most states require delivery to the site or incorporation into the work. Consult a construction attorney in your state if you are in this situation.
Can retainage from two years ago still be liened?
Possibly, but lien filing deadlines are strict and vary by state. In California, a claimant has 90 days from completion of the project to record a lien under Cal. Civ. Code § 8412. In Florida, the deadline is 90 days from the last day of furnishing under Fla. Stat. § 713.08. If the deadline has passed, your lien remedy may be gone—but a breach-of-contract or unjust enrichment claim may still be available. Run your dates before filing anything.
Does a mechanics lien include interest on the unpaid amount?
Generally, interest is not included in the lien face amount, but it may be recoverable in a lien foreclosure lawsuit. Florida Stat. § 687.01 sets a default interest rate for obligations where no rate is specified. California and Texas courts have discretion to award interest in foreclosure proceedings. Do not inflate your lien amount by adding interest—include only the principal unpaid amount.
Can a supplier file a mechanics lien for the same items a subcontractor is liening for?
Yes, but the total recovery across all liens on a project is generally limited to the contract price. Both a subcontractor and the supplier who sold materials to that subcontractor can file liens, but the owner's exposure does not stack infinitely—courts will sort out priority and allocation in a foreclosure action. Both parties should file to protect themselves; neither should omit their lien because the other is filing.
What happens if I accidentally overstate my lien amount?
In California, a willfully exaggerated lien is void under Cal. Civ. Code § 8422, and the claimant may face liability for the owner's attorney fees. In Florida, overstating a lien can expose you to a claim for damages including attorney fees. The word "willfully" matters—an honest mistake supported by documentation is different from padding a number. Keep your records, and your lien amount will be defensible.
Can a sub-subcontractor lien for the same costs the subcontractor is liening for?
Yes. Sub-subcontractors have independent lien rights in every LienFlash state, provided they served the required preliminary notice. A sub-sub's lien is for amounts owed by the subcontractor that the sub-sub can trace to work furnished on the project. Both the sub and the sub-sub can file valid liens simultaneously.
Do I need a written contract to file a mechanics lien?
No. Most state statutes allow liens based on the reasonable value of work furnished even without a written contract. California, Florida, Texas, and Washington all permit recovery on a quantum meruit basis when no contract price is established. A written contract makes your lien amount easier to document and defend, but its absence is not a bar to filing.
