Contractors, subcontractors, material suppliers, equipment lessors, and design professionals all have the legal right to put a lien on a property when they furnish labor, materials, or services and don't get paid. This right — called a mechanics lien — is created by statute in every U.S. state and attaches directly to the property title, not just to a contract. For residential property owners, that means a lien can cloud the title and block a sale or refinance until it's resolved. For the subcontractors and suppliers who hold lien rights, it's the single most powerful collection tool available — but most states require specific preliminary notice steps before a lien can be filed. Miss those steps and you lose the right entirely.
Who Has the Legal Right to File a Mechanics Lien?
Anyone who directly contributes labor, materials, or services to the improvement of real property has statutory lien rights in most states. That covers a broader group than most property owners — or even most subs — realize.
The following parties generally qualify:
- General contractors — directly contracted with the property owner
- Subcontractors — hired by the GC or another sub (first-tier, second-tier, sometimes third-tier depending on the state)
- Material suppliers — companies that supply lumber, fixtures, concrete, roofing materials, HVAC equipment, and similar goods
- Equipment lessors — companies that rent machinery or tools used on the job site
- Design professionals — architects, engineers, surveyors, and landscape architects whose work improves the property
- Labor-only workers — in many states, individual workers (not just companies) can file liens for unpaid wages
The specific tier cutoff varies by state. Florida, for example, extends lien rights to sub-subcontractors and material suppliers to subcontractors under Fla. Stat. § 713.01. California extends rights to anyone in the "chain of improvement" under Cal. Civ. Code § 8400. Texas limits claimants more strictly and requires written contracts in certain scenarios under Tex. Prop. Code § 53.021.
What does not typically qualify: general laborers paid as employees (their claims go through wage boards, not lien statutes), suppliers who sell to suppliers without direct job-site delivery, and parties whose work doesn't permanently improve the real property.
Does a Subcontractor Who Has No Contract With the Owner Still Have Lien Rights?
Yes — and this is the part most property owners don't know until it's too late. A subcontractor's lien rights exist by statute, not by privity of contract with the owner. You hired a GC. The GC hired an electrician. The GC doesn't pay the electrician. That electrician can file a lien on your property even though you never signed anything with them.
This is the foundational principle behind mechanics lien law. Every state has enacted these statutes specifically to protect the laborers and suppliers who physically improve a property but have no direct relationship with the person who owns it.
For property owners, the practical risk is significant: you can pay your GC in full and still end up with liens filed by unpaid subs. That's why most states have created owner protection mechanisms — like Florida's Notice of Commencement system or the conditional/unconditional lien waiver exchange process — to give owners a paper trail confirming subs have been paid before funds flow.
For subcontractors and suppliers, the takeaway is equally important: your lien rights don't depend on the owner knowing you exist. But you do have to follow the statutory notice procedures to keep those rights alive.
What Is a Preliminary Notice and Why Does It Affect Lien Rights?
A preliminary notice (also called a pre-lien notice, notice to owner, or notice of right to lien depending on the state) is a formal written notice that a subcontractor, supplier, or other claimant must send early in a project to preserve their right to later file a mechanics lien. Most states require it. Skipping it is the most common reason lien claims get thrown out.
Here's how it works in the states where LienFlash operates:
- Florida: Sub-subcontractors and suppliers must serve a Notice to Owner within 45 days of first furnishing under Fla. Stat. § 713.06(2)(c). GCs are not required to serve the notice. Failure to serve is a complete bar to lien rights for those who are required to file.
- California: Subcontractors, material suppliers, and equipment lessors must serve a 20-Day Preliminary Notice within 20 days of first furnishing under Cal. Civ. Code § 8200. Late service limits protection to the 20 days prior to service.
- Arizona: Subcontractors and suppliers must serve a Preliminary 20-Day Notice within 20 days of first furnishing under Ariz. Rev. Stat. § 33-992.01. Failure is a complete bar to lien rights on private projects.
- Nevada: All parties except direct GCs must serve a Notice of Right to Lien within 31 days of first furnishing under NRS § 108.245.
- Washington: Subcontractors and suppliers must serve a Notice to Owner within 60 days of first furnishing under RCW § 60.04.031.
- Oregon: Subcontractors and suppliers must serve a Notice of Right to a Lien within 8 business days of first furnishing under ORS § 87.021. Oregon's deadline is among the tightest in the country.
- Texas: Subcontractors must send a notice to the GC and owner by the 15th day of the second or third month following the month labor or materials were furnished, depending on whether they have a direct contract with the GC, under Tex. Prop. Code § 53.056.
- New Mexico: Subcontractors and suppliers must serve a preliminary notice within 60 days of first furnishing under NMSA § 48-2-2.1.
The deadline clock starts on the date you first show up to the job or deliver the first materials — not when the invoice goes out, not when the problem starts. That's a critical distinction. Waiting until payment is late to think about preliminary notices is almost always too late.
How Does a Mechanics Lien Actually Affect a Property?
A recorded mechanics lien attaches to the property's title as an encumbrance. Once it's recorded with the county, it shows up in any title search. That has two immediate practical effects.
First, the property generally cannot be sold or refinanced with a clean title while the lien is active. Title insurance companies will not issue a policy over an outstanding mechanics lien. Lenders won't fund a purchase or refi with unresolved title issues. This is the leverage that makes mechanics liens effective — it forces a resolution because the owner needs a clear title to do anything with the property.
Second, if the debt goes unpaid and the lienholder takes the matter to court, a judgment can result in a forced sale of the property to satisfy the lien. This is rare in practice — most liens get resolved through negotiation or payment long before foreclosure — but the statutory authority exists.
For a residential property owner, a lien filed by an unpaid subcontractor is not just a nuisance. It's a title defect that sits on the property until it's formally released. Even after a debt is paid, the lienholder must file a lien release (or the owner can take legal action to compel one). The lien doesn't disappear automatically.
Are There Deadlines for Filing the Mechanics Lien Itself?
Yes, and they're separate from the preliminary notice deadlines. After doing the work, a claimant has a window to file the lien with the county recorder's office. That window is typically measured from project completion, last furnishing date, or recordation of a Notice of Completion.
Key filing deadlines by state:
- Florida: 90 days from last furnishing under Fla. Stat. § 713.08
- California: 90 days from completion of the project (or 60 days if a Notice of Completion or Cessation was recorded) under Cal. Civ. Code § 8412–8414
- Arizona: 120 days from substantial completion under Ariz. Rev. Stat. § 33-993
- Nevada: 90 days from last furnishing under NRS § 108.226
- Washington: 90 days from last furnishing under RCW § 60.04.091
- Oregon: 75 days from last furnishing under ORS § 87.035
- Texas: The 15th day of the fourth month after the month in which the work was completed under Tex. Prop. Code § 53.052
- New Mexico: 120 days from last furnishing under NMSA § 48-2-7
Missing the lien filing deadline is fatal to the claim. There's no extension, no cure, no exception for "I didn't know." The right simply expires.
What Types of Liens Other Than Mechanics Liens Can Attach to a Property?
Mechanics liens aren't the only type of lien that can cloud a property title. Understanding the full landscape helps both property owners and contractors know what they're dealing with.
Tax liens: The IRS and state tax agencies can file liens against property for unpaid federal or state taxes. Federal tax liens are governed by 26 U.S.C. § 6321 and attach to all property owned by the taxpayer.
Judgment liens: When a court enters a money judgment against a property owner and the creditor records it, it becomes a lien on any real property the debtor owns in that county. The rules vary by state but most allow judgment liens under general creditor statutes.
HOA liens: Homeowners associations can lien property for unpaid dues and assessments. In many states, HOA liens can even be superior to mortgage liens under certain circumstances.
Mortgage/deed of trust liens: These are voluntary liens created when an owner borrows money secured by the property. They're the most common lien type and sit at the top of the priority chain on most residential properties.
Child support liens: Many states allow child support agencies to file liens against real property for unpaid support obligations.
For construction industry purposes, the mechanics lien is the one that's most directly within a subcontractor's or supplier's control to create — and to protect through proper preliminary notice procedures.
What Happens If You Don't Send a Preliminary Notice in Time?
In most states, failing to send a required preliminary notice is a complete bar to mechanics lien rights. Not a partial reduction. Not a procedural technicality that a judge might overlook. A complete bar.
That means if you're a Florida sub-subcontractor who skips the Notice to Owner and then doesn't get paid, you cannot file a lien. Your only remaining options are suing on the contract (breach of contract claim, not a lien claim) or filing in small claims court — both of which are slower, more expensive, and don't carry the same leverage as a lien on the property.
According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years prior. Slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending. Mechanics lien rights are one of the few tools subs have to push back against that payment gap — but only if those rights are preserved through timely notice.
The math on filing a preliminary notice is straightforward: a single notice through LienFlash costs $24.99. If it preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, the return on that $24.99 is roughly 60,000%. On a $75,000 contract, the return exceeds 300,000%.
The question isn't whether it's worth sending the notice. The question is why you'd risk your right to get paid on a job by not sending one.
Frequently Asked Questions
Can a subcontractor put a lien on my house without warning?
In most states, yes — at least from the property owner's perspective. Subcontractors generally have the right to file a mechanics lien without notifying the owner in advance, as long as they've met any preliminary notice requirements that apply to their tier. Some states, like Florida, require subs and suppliers to serve a Notice to Owner before they can lien, which does give owners advance notice. But in states with no preliminary notice requirement for certain parties, a lien can appear on your title without warning.
Can a general contractor lien a property?
Yes. General contractors typically have direct lien rights against the property because they contract directly with the owner. In most states, GCs are not required to send a preliminary notice before filing — that requirement generally applies to second-tier and lower parties who have no direct relationship with the owner.
How long does a mechanics lien stay on a property?
This varies by state. Most mechanics liens expire if the claimant doesn't file a lawsuit to enforce the lien within a set period after recording. In California, the claimant must file suit within 90 days of recording the lien under Cal. Civ. Code § 8460. In Florida, the lien expires one year after recording unless suit is filed under Fla. Stat. § 713.22. An expired lien is unenforceable, but it may still cloud the title until formally released.
Can a lien be placed on a rental property or commercial property?
Yes. Mechanics lien statutes apply to all types of real property improvements — residential, commercial, industrial, and rental properties. The procedures and deadlines may differ based on whether the project is a private or public work, and some states have additional rules for owner-occupied residential properties, but the lien right itself is not limited to any property type.
What's the difference between a mechanics lien and a lien waiver?
A mechanics lien is a legal claim recorded against a property when a contractor or supplier isn't paid. A lien waiver is a document that a contractor or supplier signs, releasing (waiving) their right to file a lien, usually in exchange for payment. Lien waivers can be conditional (effective only when payment clears) or unconditional (effective immediately upon signing). Never sign an unconditional lien waiver before confirming the payment has actually been received and cleared.
Does sending a preliminary notice mean you're threatening to lien someone?
No. A preliminary notice is a routine statutory requirement — it's not a threat, demand, or claim that anything is wrong. It's simply the administrative step required to preserve your right to file a lien later if payment doesn't come. Most experienced GCs and owners expect to receive them on larger projects. Sending one early and routinely, on every job, is standard professional practice.
Can a lien be filed on a property if the homeowner already paid the GC?
Yes, unfortunately. If the GC collected payment from the owner but didn't pay the subs and suppliers, those subs and suppliers can still lien the property — even though the owner paid. This is the "double payment" problem that preliminary notice systems and conditional lien waivers are designed to prevent. An owner's best protection is to require lien waivers from all subs and suppliers before releasing final payment to the GC.
How do I find out if there's already a lien on a property?
Mechanics liens are recorded with the county recorder's (or county clerk's) office in the county where the property is located. Most counties have searchable online databases. A title search — typically performed by a title company during any real estate transaction — will surface recorded liens. If you're a property owner who suspects a lien may have been filed, check your county recorder's website or contact a title company directly.
Protect Your Lien Rights Before the Deadline Passes
Lien rights are use-it-or-lose-it. Every day you work on a job without sending the required preliminary notice is another day closer to losing your legal right to get paid. Deadlines start on the date you first furnish — not the date a dispute starts, not the date the invoice goes unpaid.
Use LienFlash's free deadline calculator to find your exact preliminary notice deadline based on your state and first-furnishing date. Filing takes two minutes, costs $24.99 per notice, and comes with an attorney-reviewed state-compliant form sent via USPS Certified Mail with a Certificate of Mailing PDF you can keep on file.
Don't hand over your strongest payment protection tool by missing a deadline. File the notice. Keep the right.
