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, 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?

The majority of states require some form of preliminary notice, but the requirements vary dramatically. Here is a general overview:

States requiring preliminary notice for subcontractors and suppliers:

• California: 20-day preliminary notice required. Must be sent within 20 days of first furnishing labor or materials. One of the strictest states.
• Arizona: 20-day preliminary notice. Similar to California. Must include specific statutory language.
• Florida: Notice to Owner must be served within 45 days of first furnishing.
• Texas: Notices must be sent by the 15th day of the second month after labor or materials are first furnished. The Texas system is particularly complex.
• Nevada: 31-day preliminary notice for commercial projects. Residential projects follow different rules.
• Georgia: Notice of Commencement filed by the owner triggers requirements for subcontractors.

States where preliminary notices are optional but recommended:

Some states do not require a preliminary notice to preserve lien rights, but sending one anyway is still considered best practice. It puts the property owner on notice and often encourages timely payment. States like New York, Pennsylvania, and Illinois fall into this category for certain project types, though each has its own nuances.

States with no preliminary notice requirement:

A handful of states allow contractors and subcontractors to file a mechanics lien without any prior notice to the property owner. However, even in these states, 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:

| State | Deadline | Who Must Send | |-------|----------|---------------| | California | Within 20 days of first furnishing | Subcontractors, suppliers | | Arizona | Within 20 days of first furnishing | Subcontractors, suppliers | | Florida | Within 45 days of first furnishing | Subcontractors, sub-subs, suppliers | | Texas | By the 15th of the 2nd month after first furnishing | Subcontractors, suppliers | | Nevada | Within 31 days of first furnishing | Most claimants on commercial projects | | Washington | Within 60 days of first furnishing | Subcontractors, suppliers |

These deadlines are calculated from the date you first provided labor or delivered materials -- not from the date you completed work or the date payment was due. This is a critical distinction that catches many contractors off guard.

What Happens If You Miss the Deadline?

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

Total loss of lien rights. In strict states like California and Arizona, failing to send the preliminary notice within the required window eliminates your right to file a mechanics lien. There is no exception, no extension, and no appeal.

Partial loss of lien rights. Some states allow a late preliminary notice but limit your lien to work performed after the notice was sent, minus a lookback period. For example, you might only be able to lien for work done in the 20 days before you sent the notice and everything after. All work before that window is unprotected.

Either way, the financial impact can be devastating. A $50,000 invoice becomes uncollectable because you missed a 20-day window by a single day.

Best Practices for Preliminary Notices

Based on years of construction payment experience, 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 via certified mail with return receipt. You need proof that the notice was sent and received. Certified mail with return receipt requested provides a paper trail. Some states also accept personal delivery with a signed acknowledgment.

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.
