A pre-lien notice is a document that subcontractors, suppliers, and equipment lessors send near the start of a construction project to tell the property owner, general contractor, and lender that they are furnishing labor or materials to the job. It is not a lien and does not signal a payment problem. Its only job is to preserve the sender’s right to file a mechanic’s lien later if payment does not come through. Roughly half the states require some version of it, and the rules on who, what, when, and how differ enough from state to state that the details matter far more than the concept.
Who Has to Send One
The requirement almost always falls on parties without a direct contract with the property owner. Subcontractors hired by the general contractor, material suppliers delivering to the job site, and companies leasing equipment to the project are the typical senders. If you sit two or more steps away from the owner in the contract chain, assume you need to send one unless your state’s statute clearly exempts you.
General contractors who hold a signed contract directly with the owner usually do not need to send a preliminary notice, because the owner already knows they are on the job. A few states still require it from general contractors on certain project types, but that is the exception. The further you are from the person writing the checks, the more important this notice becomes.
What the Notice Must Include
Contents vary by jurisdiction, but nearly every state’s version calls for the same core information:
- Your full legal name, business name, and mailing address.
- The name and address of the party that hired you, usually the general contractor or a higher-tier subcontractor. This establishes where you sit in the contract chain.
- A general description of the labor, materials, or equipment you are providing. A line-item breakdown is not required, but the description should be specific enough that the owner understands what you are contributing.
- The street address of the job site, and in some states the legal property description from public records.
- A reasonable estimate of the total price of your work or materials. The number does not lock you in, but it should reflect your actual expected contribution.
- Any statutory warning language the state requires. Some states mandate specific language, word for word, informing the owner that the sender may have lien rights. Leaving out mandatory language can void the notice entirely.
Finding the Right Recipients
The notice has to reach the correct people to count. You generally need the property owner’s legal name and address, the general contractor’s information, and often the construction lender’s details. A second-tier subcontractor may not have any of this when work begins.
In states that use a notice of commencement, the owner or general contractor files a document with the county recorder at the start of the project listing the owner, contractor, and lender. That filing is supposed to be a one-stop source. In practice, finding it can be frustrating. County recorder records are not always searchable online, indexing methods vary, and some offices charge access fees or require an in-person visit. Start with the county recorder where the project is located. If no notice of commencement is on file, ask the general contractor directly for the owner and lender information, and document your efforts in case the notice is later challenged.
Deadlines Vary Sharply by State
The single most important thing about preliminary notice deadlines is that they differ dramatically from state to state. Arizona and California require the notice within 20 days of first furnishing labor or materials. Florida gives you 45 days. Georgia allows 30 days. Oregon sets a tight window of eight business days. Some states measure from the start of your work; others measure from project completion. A few require the notice before any work begins.
The 20-day window gets cited often as the “standard” deadline, and it is a reasonable default assumption until you have looked up your state’s rule. Treating it as universal is a mistake that costs people their lien rights every year. Look up the specific requirement in the state where the project is located, not the state where your business is based. Construction lien law follows the project’s location.
A missed deadline does not always mean total loss. Some states accept a late notice but limit lien protection to work performed within a set number of days before the notice actually went out. That is better than nothing, and still worse than being on time: it can wipe out lien rights for thousands of dollars of earlier work. The safest approach is to send the notice the same week you start on a project, before the deadline question even becomes relevant.
How to Deliver It
Delivery method matters because you may need to prove receipt if a dispute reaches court. Most states accept certified mail with return receipt requested, and that is the most common approach because it creates a paper trail showing exactly when the recipient received the document. Registered mail and personal delivery with a signed acknowledgment also work in most jurisdictions. Some states allow regular first-class mail, but relying on it is risky because you cannot prove delivery. A few states permit electronic delivery, though that remains uncommon for preliminary notices.
Whatever method you use, keep copies of the notice itself, the proof of mailing or delivery, and any return receipts. Those records become critical evidence if you later need to file and enforce a mechanic’s lien.
What Happens If You Skip It or Send It Late
Skipping the preliminary notice or sending it late can cost you your mechanic’s lien rights entirely. That is not a theoretical risk. A mechanic’s lien is the most powerful collection tool available to construction parties because it attaches directly to the property. The owner cannot sell or refinance without resolving it, which creates real pressure to pay. Without lien rights, you are left pursuing a breach-of-contract claim against whoever hired you, which is slower, more expensive, and depends entirely on that company’s ability to pay. If the general contractor who owes you money files for bankruptcy, an unsecured contract claim may be worth nothing. A lien on the property would have survived.
The stakes are highest for suppliers and lower-tier subcontractors whose only connection to the project may be a purchase order. For them, the preliminary notice is the price of admission to the mechanic’s lien system. Treat it as standard paperwork on every project, not something to think about only when payment looks shaky. By the time you suspect a problem, the deadline has usually already passed.
Public Projects Use Bond Claims Instead
Mechanic’s liens do not apply to public property. You cannot place a lien on a government building or a public road. Federal and state law substitute payment bonds that serve a similar protective function, with their own notice rules and deadlines. On federal projects over $100,000, the Miller Act requires a payment bond, and second-tier parties must give written notice to the prime contractor within 90 days of last furnishing labor or materials. Nearly every state has its own “Little Miller Act” covering state and often local public projects, with its own thresholds and deadlines. If the project is public, the pre-lien notice process in this article does not apply; check the applicable bond statute instead.
What Comes After the Notice
Sending a preliminary notice does not mean you are headed for a dispute. Most of the time the notice sits in a file and never matters because everyone gets paid. When payment problems do surface, the notice is what keeps your options open.
If payment still is not coming after the notice goes out, the typical progression moves through informal demand, then a formal notice of intent to lien in states that require one as a final warning, then the mechanic’s lien filing with the county recorder. Lien filing deadlines also vary by state and run from different trigger points: your last day of work, the date of project completion, or the recording of a notice of completion. In many states, the window falls somewhere between 60 and 90 days after the relevant trigger.
Filing the lien is not the end. You then have a limited time to file a lawsuit to enforce the lien or it expires, and that enforcement deadline can be as short as six months in some states. The preliminary notice, the lien filing, and the enforcement lawsuit are three separate steps with three separate deadlines, and missing any one of them can unravel the whole chain. Keep a calendar with every deadline marked from the day you first show up on a job site.
