Preliminary Notice Requirements for Subcontractors: A State-by-State Guide

If you're a commercial subcontractor, the preliminary notice might be one of the most important documents you're not sending—or perhaps worse, sending too late. Missing the deadline doesn’t merely result in a slap on the wrist. In many states, it can result in the forfeiture of your right to file a mechanic's lien should you not receive payment for work performed or materials furnished. 

Here, I’ll break down exactly which states require subcontractors to send preliminary notices, the deadlines you need to meet, and what's at stake if you don't.

What Is a Preliminary Notice in Construction?

A preliminary notice (sometimes called a pre-lien notice, notice to owner, or notice of furnishing) is a legal document that subcontractors, suppliers, and other parties send near the start of a construction project. It notifies the property owner, general contractor (GC), and construction lender (if applicable) that: 

1. you're providing labor or materials on the project and
2. that you have the right to file a lien if you're not paid.

It's also important to understand what a preliminary notice is not: It is not a threat, and it is not a lien. It's basically a heads-up, introducing your business to the payment chain. And it’s an appreciated one. 

Research shows that more than 83% of notice recipients view the document as helpful or routine. Property owners and GCs want to know who's working on their projects because it helps them manage payments and avoid surprises down the road.

A preliminary notice is also different from a notice of intent to lien (NOI), which is a more aggressive document sent later warning the owner that you intend to file a lien. These typically come into play if a payment dispute develops. 

Ultimately, if you're a subcontractor working on a project where you don't have a direct contract with the property owner, there's a good chance your state requires you to send a preliminary notice to protect your lien rights. Skip it or miss the window, and you may be handing over your most powerful payment-recovery tool without even realizing it.

Why Preliminary Notices Matter for Subcontractors

For subcontractors, the stakes are straightforward: Your right to file a mechanic's lien is often the strongest leverage you have to collect payment when a GC or owner stops paying. But in the majority of states, that right is conditional, as you must send a preliminary notice first.

Here's what you risk by not sending one:

Loss of Lien Rights

In strict states like Iowa, failure to send a preliminary notice can mean total forfeiture of your right to file a lien. While in states like California, a late notice doesn't wipe out your rights entirely, but it does limit your lien claim to only the work performed within 20 days before you sent the notice, potentially leaving substantial money unprotected.

Loss of Bond Claim Rights

On public projects, where mechanic's liens don't apply, your right to make a claim against a payment bond often depends on having sent a timely preliminary notice. No notice, no bond claim.

Weakened Negotiating Position

Even when a notice isn't strictly required, sending one signals that you know your rights and that you'll enforce them. GCs and owners tend to pay faster when they know a lien is possible.

The good news is that making preliminary notices a standard part of your project-kickoff process (whether or not your state technically requires them) protects you across the board. It's a best practice that can directly improve your cash flow and reduce payment disputes.

States that Require Preliminary Notices from Subcontractors

Referencing Siteline’s lien rights by state directory, most states require subcontractors to send some form of preliminary notice, though only a handful require it under certain conditions (like specific project types or dollar thresholds). The exact count depends on how those conditional states are classified.

Below is a breakdown of each state's preliminary notice requirements as they apply to subcontractors who have a direct contract with the GC. Keep in mind that these are general guidelines—always verify your state’s current statutes before starting a project. (And for requirements that apply to other roles, see our lien rights by state directory.)

Alaska

It’s recommended, though not required, for subcontractors in Alaska to send a Notice of Right to Lien to the property owner at the start of the project, as it ensures you maintain the full 120-day lien filing window, rather than being cut to only 15 days in the event the owner records a Notice of Completion.

Arizona

Arizona requires subcontractors to send a 20-Day Preliminary Notice within 20 days of first furnishing any work. The property owner, GC, and construction lender all must receive the notice. If you send the notice late, lien rights are lost for any work done before it was served.

Arkansas

Arkansas uses what’s called a Notice to Owner form, but the rules vary by project type: 

• For commercial and large residential projects (five units or more), the Notice to Owner must be sent within 75 days of furnishing work.
• For smaller residential projects (one to four units), the notice is only required if the GC didn’t provide the owner with their preliminary notice (Residential Lien Warning Notice).

California

California's 20-Day Preliminary Notice is one of the most well-known preliminary notice requirements in the country. Subcontractors must send notice to the property owner, GC, and construction lender (if any) within 20 days of first furnishing work, using an approved delivery method—certified mail, registered mail, or express/overnight delivery.

This notice must include the statutory warning language outlined in CA Civ Code § 8202.

Late notices are allowed, but coverage is limited to work performed in the 20 days before the notice was sent, plus any work furnished afterward. 

Colorado

In Colorado, subcontractors are not required to send a preliminary notice, but they may choose to send a voluntary notice to the owner during the project, because once the owner receives it:

1. they must withhold enough funds from the GC to cover the claimed amount, and 
2. an owner who pays the GC after receiving the notice may become personally liable for the unpaid balance.

While this notice does not replace the required 10-day Notice of Intent to Lien or extend lien filing or enforcement deadlines, it can increase leverage and ensure you get paid without ever having to file a lien.

Florida

Subcontractors in Florida must send a Notice to Owner to the property owner, GC, and any applicable surety or lender within 45 days of first furnishing labor or materials. This is a firm deadline. Missing it forfeits your lien rights for work performed more than 45 days before the notice was sent. 

Florida's Notice of Commencement (NOC) process also plays a role here, because the NOC contains the information you'll need to complete your Notice to Owner.

Georgia

Georgia requires subcontractors to send a Notice to Contractor and property owner within 30 days of first furnishing labor or materials, but only when a Notice of Commencement has been filed (by the GC) on the project. If no NOC is filed, the notice requirement may not apply, though it's still a best practice to send one.

Illinois

In Illinois, a preliminary notice is only required on owner-occupied, single-family residential jobs. In those cases, the notice must be sent within 60 days of starting work. It isn’t required in any other situations.

Indiana

Indiana only requires a preliminary notice for certain owner-occupied single- or double-family residential projects. 

For repair or alteration work on these projects, the notice must be sent to the owner within 30 days of first furnishing labor or materials. For any original construction, the notice must be provided to the owner and filed with the county recorder within 60 days of first furnishing.

Iowa

To preserve your lien rights in Iowa, subcontractors must post a preliminary notice either:

• within 30 days of first furnishing labor or materials on commercial projects, or
• before the owner pays the GC on residential projects. 

Iowa requires notices to be posted through its Mechanic's Notice and Lien Registry. And for residential projects, it’s worth noting that the state's Notice of Commencement requirements are tied directly to the lien process.

Kansas

Subcontractors working on residential projects in Kansas with claims exceeding $250 must mail a warning statement to property owners at the start of the project. Without it, lien rights on residential work may be lost.

Michigan

In Michigan, subcontractors must send a preliminary notice—known as a Notice of Furnishing—to the property owner, GC, and construction lender within 20 days after the first day of work.

Minnesota

In Minnesota, subcontractors must deliver a written notice to the owner within 45 days of first furnishing labor or materials.

Mississippi

Subcontractors must send a preliminary notice in Mississippi within 30 days after the first day of work or the delivery of materials. This 30-day requirement does not apply to single-family residential construction.

Missouri

Requirements in Missouri are pretty narrow for subcontractors: For owner-occupied residential remodels (four units or fewer), lien rights for parties other than the GC typically require a signed Consent of Owner in the statutory form, and it must be attached to the lien filing. 

Montana

In Montana, subcontractors must send the owner a Notice of Right to Claim a Lien. The notice must be delivered by certified mail or personal delivery, and within 20 days of first furnishing labor or materials (or 45 days for non-owner-occupied projects funded through a regulated lender’s loan secured for that improvement).

Nevada

Subcontractors in Nevada must serve a Notice of Right to Lien to the property owner and GC within 31 days of first furnishing work. Filing late limits your lien rights to work completed within the 31 days before the notice is served and anything after that. Earlier work isn’t lienable.

New Hampshire

In New Hampshire, subcontractors not only must give written notice to the owner before work begins and continue providing itemized statements for work performed every 30 days to preserve lien rights.

If the notice is sent late, lien rights are limited to the funds the owner still owes the GC at the time the notice is received.

New Jersey

In New Jersey, preliminary notices are only required on residential projects. Subcontractors must file a Notice of Unpaid Balance (NUB) within 60 days of last furnishing and start mandatory arbitration within 10 days of filing the NUB. Without either of these steps, lien rights are lost on residential work.

North Carolina

For subcontractors working on projects where the owner designates a lien agent (generally required on contracts that are $40,000 or more), North Carolina requires they send a Notice of Lien Agent within 15 days of first furnishing. The lien agent system is unique to North Carolina, and missing a required notice can limit lien priority.

Ohio

Ohio requires subcontractors to file a Notice of Furnishing within 21 days of first providing labor or materials, but only when the owner files a Notice of Commencement.

Oklahoma

Oklahoma subcontractors must send a pre-lien notice within 75 days after last furnishing if the claim exceeds $10,000 on a non-residential project, or the project is an owner-occupied residential project (any amount). 

If you’re required to send this notice, you must also file a notarized Affidavit of Compliance together with the lien statement. 

Oregon

Subcontractors in Oregon must send a Notice of Right to a Lien within eight business days of starting work, unless they have a direct contract with the owner. If the notice is sent late, lien rights are limited to work performed in the eight business days immediately before the notice was delivered—plus any work furnished afterward.

Pennsylvania

In Pennsylvania, subcontractors must submit a Notice of Furnishing within 45 days of first furnishing work for projects:

1. that qualify as “searchable” (i.e., projects costing $1.5M or more), and
2. where the owner has filed a Notice of Commencement. 

South Carolina

Subcontractors in South Carolina who are not in direct contract with the owner must give written notice to the owner in order to preserve their lien rights. There is no statutory deadline, but best practice is to send the notice as soon as work begins.

Tennessee

Though not a traditional preliminary notice, commercial subcontractors in Tennessee must send a monthly Notice of Nonpayment to the owner and prime contractor within 90 days of the last day of each month in which they furnished any unpaid work. If these aren’t sent, lien rights are typically lost.

Texas

Texas has one of the most complex preliminary notice systems in the country. Subcontractors must send monthly notices for any unpaid work via certified mail to the property owner and GC. These notices are due by the 15th day of the second month (for residential projects) or by the 15th day of the third month (for commercial projects) after the month in which the unpaid work was performed.

Texas also has separate notice requirements for contractual retainage claims, which follow different deadlines based on when work was last furnished. Missing a monthly notice deadline forfeits your lien rights for that period.

Utah

Utah requires subcontractors to file a preliminary notice within 20 days of first furnishing work. The notice must be filed through the Utah State Construction Registry, an online system that centralizes notice filings for the state. Missing the 20-day window doesn’t automatically kill lien rights, but it does limit them to work performed just before the notice is filed.

Virginia

Virginia has a very narrow notice requirement. On residential one- and two-family projects where the posted building permit names a mechanic's lien agent, subcontractors must notify that agent within 30 days of first furnishing (or within 30 days of permit issuance if work began earlier). If that deadline is missed, a lien may still be filed, but it’s generally limited to work furnished on or after the date the notice is sent.

Washington

In Washington, subcontractors must send a preliminary notice—called a Notice of Right to Claim a Lien—but the deadline depends on the project type:

• 10 days from first furnishing for single-family residential projects
• 60 days from first furnishing for commercial projects 

A late notice doesn't eliminate lien rights entirely, but it does limit them to work performed within the applicable 10- or 60-day window before notice was given, plus any work performed after. Best practice is to send the notice via certified mail or personal delivery.

Wisconsin

In Wisconsin, most subcontractors must serve a Notice of Right to Lien within 60 days of first furnishing labor or materials. The notice must be prepared with two signed copies and delivered to the property owner. 

Wyoming

Wyoming requires subcontractors to send a Preliminary Notice of Right to Lien to the property owner and GC within 30 days of first furnishing. The state also requires that the notice substantially follows the form set out in Wyo. Stat. § 29-10-101.  Missing this window forfeits lien rights entirely.

Preliminary Notice Rules at a Glance

This is a lot of information to sift through. Here’s a simplified breakdown you can quickly scan.

States That Don't Require Preliminary Notices

If your state isn't on the list above, there's no statutory requirement to send a preliminary notice as a subcontractor. But that doesn't mean you shouldn't.

Even in states without mandatory notice requirements, sending a voluntary preliminary notice is a best practice that signals professionalism, puts you on the property owner's radar, and can speed up payments. It costs very little and provides an added layer of protection if a payment dispute ever arises.

Best Practices for Managing Preliminary Notices

1. Send a preliminary notice on every project. Even if your state doesn’t require it, making this a standard part of your process eliminates the risk of accidentally skipping one on a project where it's mandatory. It also boosts your visibility with property owners and GCs.
2. Send it early. Don't wait until the deadline is approaching. Send your notice either right before or as soon as you begin work or deliver materials. The sooner you send it, the less likely you are to lose coverage for early work.
3. Know your state's delivery requirements. Some states require certified mail or registered mail. Others accept personal delivery or overnight carriers. Using the wrong delivery method could invalidate your notice.
4. Track your deadlines. Especially if you’re running multiple projects in multiple states, it's easy for a deadline to slip through the cracks. Calendar reminders and spreadsheets require manual inputs and management, so we advise implementing lien rights management software, which tracks deadlines and requirements on your behalf and alerts you to take action.
5. Keep proof of service. Always retain documentation that your notice was sent and received. If you ever need to file a lien, you'll need to prove that you sent the preliminary notice on time.
6. Review state rules at the start of every project. Especially if you work across state lines, take a minute to confirm the specific notice name, deadline, recipients, form requirements, and delivery method for each job.

Preliminary notices are a small administrative step that can make the difference between having leverage to collect payment and being completely out of options. But as you can see, managing them—especially across state lines—can be tricky and time-consuming. 

Siteline’s lien rights management capabilities helps subcontractors automatically track preliminary notice requirements, generate the correct forms, and send them on time, every time.
