Preliminary Notice Requirements by State: What You Need to Know

Before you can file a mechanics lien in most states, there is one critical step you cannot skip: sending a preliminary notice. Miss this step and you may lose your lien rights entirely, or for part of your work, even if the property owner owes you tens of thousands of dollars. Preliminary notices are one of the most commonly overlooked requirements in construction payment protection, and failing to send one on time is one of the most expensive mistakes a contractor can make.

What Is a Preliminary Notice?

A preliminary notice — also called a notice to owner, pre-lien notice, or notice of furnishing depending on the state — is a document you send to the property owner and sometimes the general contractor at the beginning of a project. It serves as a formal heads-up that you are providing labor, materials, or services to their property and that you have the right to file a mechanics lien if you are not paid.

Preliminary notices are not a threat. They are not a lien filing. They are not adversarial. In fact, most property owners appreciate receiving them because it helps them track who is working on their project and manage their payment obligations.

Think of it this way: the preliminary notice tells the property owner, "I am here, I am contributing to your project, and I expect to be paid." It preserves your right to take legal action later if needed.

Why Are Preliminary Notices Required?

The logic behind preliminary notices is straightforward. On a large construction project, the property owner contracts with a general contractor, who then hires subcontractors, who may hire their own subcontractors, who order materials from suppliers. The property owner may have no idea who is actually working on their property three or four tiers down the contractual chain.

Preliminary notices solve this visibility problem. They ensure the property owner knows exactly who is contributing to the project and who may have lien rights against their property. This gives the owner the ability to verify that payments are flowing down to everyone involved.

Without a preliminary notice system, a property owner could pay the general contractor in full, only to discover months later that subcontractors were never paid and are now filing liens against the property. Preliminary notices prevent this surprise.

Which States Require Preliminary Notices?

Most states require some form of preliminary notice from at least some claimants, but the requirements vary dramatically. Here is an overview of some of the states people ask about most; each links to its full guide:

States requiring preliminary notice for subcontractors and suppliers:

• California: within 20 days of first furnishing, from subcontractors, suppliers, equipment lessors and design professionals. A direct contractor gives it only to the construction lender, when there is one (Cal. Civ. Code §§ 8200, 8204).
• Arizona: within 20 days of first furnishing, from everyone except a person performing labor for wages, general contractors included, with the contents the statute prescribes (Ariz. Rev. Stat. § 33-992.01).
• Florida: a Notice to Owner within 45 days of first furnishing, and before the owner's final payment to the contractor (Fla. Stat. § 713.06(2)(a)).
• Texas: a notice for each month of unpaid work, by the 15th day of the 3rd month after that month on commercial work or the 2nd month on residential work (Tex. Prop. Code § 53.056).
• Nevada: a Notice of Right to Lien within 31 days of first furnishing, from subcontractors and suppliers; a late notice covers only work in the 31 days before you sent it (NRS 108.245).
• Georgia: where a Notice of Commencement has been filed, subcontractors and suppliers send a Notice to Contractor within 30 days of first furnishing (O.C.G.A. § 44-14-361.5).

States where preliminary notices are optional but recommended:

Some states require a notice only on certain jobs. Tennessee's monthly Notice of Nonpayment applies to commercial work, not to homes of one to four units; Montana, Indiana and New Jersey require a notice on residential work but not commercial. Sending a notice where it is not required is still good practice: it puts the owner on notice and often encourages timely payment.

States with no preliminary notice requirement:

A few states, such as New York and Delaware, have no preliminary notice requirement at all. Even there, the filing deadlines and requirements are strict.

What Must a Preliminary Notice Include?

While the specific required content varies by state, most preliminary notices include:

• Your name and contact information (the claimant)
• The name of the person who hired you (the party you contracted with)
• The property owner's name and address
• A description of the labor, materials, or services you are providing
• The job site address or legal description of the property
• An estimated total value of the work or materials (in some states)
• Required statutory language that varies by state

Getting the content wrong can be just as damaging as missing the deadline. If your preliminary notice is missing a required element, some states will treat it as if you never sent it at all.

Common Preliminary Notice Deadlines

Here are some examples of how preliminary notice deadlines work across different states:

Most of these run from the date you first provided labor or delivered materials — not from the date you completed work or the date payment was due. That catches many contractors off guard. But not all: Texas counts from each month of work, and states such as Illinois and Kentucky count some notices from your last day. Check your state's guide.

What Happens If You Miss the Deadline?

In states that require preliminary notice, missing the deadline usually means one of two things:

Total loss of lien rights. In Florida, failing to serve the Notice to Owner on time is a complete defense to your lien. In Tennessee, a month with no Notice of Nonpayment is a month with no lien (retainage aside).

Partial loss of lien rights. Some states accept a late notice but limit your lien to work furnished in a look-back window before you sent it, and everything after: 20 days in California, 31 days in Nevada, 60 days in Washington. All work before that window is unprotected.

Either way, the financial impact can be devastating: months of billings can drop out of a claim because a notice went out late.

Best Practices for Preliminary Notices

Here are the practices that protect your rights most effectively:

Send the notice on day one. Do not wait. The moment you start work or deliver materials, send the preliminary notice. Waiting until you suspect a payment problem is almost always too late.

Send it by a method your state accepts, and keep proof. Certified mail with return receipt is common, but not universal: Arizona, for example, allows only first-class mail with a certificate of mailing, registered mail or certified mail, and hand delivery is not on the list. Your state's guide lists the methods.

Keep copies of everything. Store copies of every notice you send, along with the mailing receipt and return receipt. If you ever need to enforce a lien, you will need to prove the notice was sent on time.

Track every project independently. Each project has its own preliminary notice deadline. If you are working on five projects simultaneously, you have five separate deadlines to manage. Missing one does not affect the others, but it does cost you money on that specific project.

Use a system, not your memory. Construction professionals are busy. Relying on memory or sticky notes to track preliminary notice deadlines is a recipe for missed deadlines and lost money.
