Preliminary Notice Requirements by State
Every state regulates preliminary notices differently. This interactive map shows which states impose strict deadlines, which allow longer windows, and which require no preliminary notice at all. Hover any state for its notice name and deadline, or click for the full lien law.
Notice Requirements Map
States are color-coded by how strict their preliminary notice deadline is on private construction projects. Strict states require notice within 30 days of first furnishing and are unforgiving when deadlines are missed. Moderate states provide longer windows, typically 31 to 200 days. Conditional states require notice only for specific claimants or project types, such as residential work or remote-tier suppliers. A smaller group imposes no preliminary notice requirement before recording a lien.
- Preliminary notice is due soon after first furnishing.
- Late service is costly.
- Some states forfeit lien rights entirely (Florida).
- Others only cover recent work (California).
- A separate notice must be served for every month of unpaid work.
- One project can require multiple notices served throughout its duration.
Categorizations are general summaries of preliminary notice rules on private projects. Specific deadlines vary by claimant tier, project type, and statute. Confirm the exact requirement for your project with counsel before relying on this map.
Terminology Varies by State
Although most states require some form of preliminary notice, the statutory name of the document differs across jurisdictions. A contractor working in Florida, California, and Michigan will serve three differently named documents on the same project, each governed by its own procedural rules. The table below shows how states label their preliminary notices.

Continuing Notice States
Texas and Tennessee do not work like single-notice states. Claimants must serve a separate notice for every month that labor or materials go unpaid, so one project can generate many notices over its duration, and each unpaid month is protected only by its own timely notice.
Monthly Fund-Trapping Notices
On non-residential projects, first-tier and lower-tier subcontractors and suppliers (those who contract with the prime contractor or below) must serve a monthly notice for every month that labor or materials go unpaid.
The notice for any given unpaid month is due by the 15th day of the third calendar month following that month. For work performed in January, notice is due no later than April 15. A subcontractor with six unpaid months owes six separate notices, each tied to its own month and its own deadline.
A month not properly noticed is not trapped against funds still held by the owner, and lien rights for that month can be lost even when every other month's notice is perfect.

Subcontractors and lower-tier parties must serve a Notice of Nonpayment on both the property owner and the general contractor within 90 days of the last day of any month in which labor or materials were provided and went unpaid.
Example: work finished on April 3 runs its 90-day clock from April 30, not from April 3. The last day of the month is the trigger, not the last day of work.
A separate notice is required for each month in which unpaid work or materials were furnished, and a month without a timely Notice of Nonpayment is not lienable.

"On time" and "early enough" are not the same question. A preliminary or pre-lien notice served on the last day of its statutory window preserves lien rights the same way a notice served on day one does — but in an Unpaid Balance state, those two notices can secure very different dollar amounts.
In an Unpaid Balance state, the subcontractor's lien attaches only to the amount the owner still owes the general contractor when the lien is perfected. Every payment the owner releases to the GC while the sub is still holding its notice shrinks the pot. In a Full Price Lien state, upstream payments from the owner to the GC do not reduce the lien — the property itself is on the hook for the full value of what was furnished, so the timing question is strictly about statutory preservation.
Illinois is the clearest illustration. Under 770 ILCS 60/24, a subcontractor's 90-Day Notice may be served any time after the subcontract is signed. It must be served within 90 days after last furnishing, but nothing prevents it from being served the day the contract is executed. Because Illinois caps subcontractor liens at the owner's unpaid balance to the GC, serving at signing locks the claim in against the largest possible fund. Waiting until day 89 is timely under the statute and may attach to very little.

Frequently Asked Questions
Which states require a preliminary notice to preserve lien rights?
Most states require some form of preliminary notice from subcontractors and suppliers on private construction projects. The deadline, notice name, and required recipients vary significantly. States like California (20 days), Arizona (20 days), Utah (20 days), Michigan (20 days), Ohio (21 days), Nevada (31 days), and Florida (45 days) impose strict early-window deadlines. Other states allow longer windows or only require notice under specific conditions, such as for residential projects or remote tier claimants. A smaller group of states, including Pennsylvania, New York, Virginia, and several smaller jurisdictions, do not require a preliminary notice at all. Always confirm the exact requirement for your role, project type, and state before relying on any summary.
What happens if I miss a preliminary notice deadline?
The consequences depend on the state. In Florida, missing the 45-day Notice to Owner deadline eliminates lien rights for the entire project. In California, a late Preliminary Notice only preserves lien rights for work done within the 20 days immediately preceding service, meaning earlier work goes unprotected. Other states fall between these extremes. Because the rules vary and the stakes are high, proactive compliance tracking across every active project is the only reliable way to protect payment rights.
Do general contractors need to send preliminary notices?
In most states, general contractors in direct privity with the property owner are exempt from preliminary notice requirements because the owner already knows who they hired. A handful of states, including California in certain circumstances, still require notices from general contractors on specific project types, such as work involving a construction lender. Subcontractors, sub-subcontractors, and material suppliers are the claimants most commonly required to serve notice.
Is a preliminary notice the same as a notice of intent to lien?
No. A preliminary notice is sent at or near the start of a project to inform the owner and other parties of the sender's involvement and to preserve future lien rights. A notice of intent to lien is typically sent later, after a payment dispute has arisen, to warn that a lien will be recorded if payment is not received by a specified deadline. Some states require one, both, or neither. The two serve different functions and are usually governed by different sections of the lien statute.
Does it matter when I serve my notice within the statutory window?
Yes, especially in unpaid-balance states. The statute preserves lien rights as long as the notice is served inside the window, but the dollar amount your lien can actually reach depends on how much the owner still owes the general contractor when the lien attaches. Illinois is the clearest example: the 90-Day Notice may be served any time after the subcontract is signed and must be served within 90 days of last furnishing. Waiting to the end of that window — serving 89 days after last furnishing — is still timely under the statute, but by then the owner may have released most of the contract balance to the GC, leaving little for the lien to reach. In a Full Price Lien state, the property is on the hook for the full value furnished regardless of upstream payments, so timing is purely a statutory-preservation question.
How do I track preliminary notice deadlines across multiple states?
National Lien & Bond maintains a nationwide compliance database that identifies every applicable preliminary notice requirement for each project based on state, role, and project type. When a project is submitted, the appropriate notice is drafted, attorney-reviewed, and served within the statutory window, and all deadlines are calendared and confirmed. This removes the burden of tracking fifty-plus separate rule sets and ensures that no deadline is missed on any active project.
