Preliminary Notice vs Notice to Owner — What's the Difference

Preliminary notice and Notice to Owner are two terms that describe the same general concept — a written notification that a subcontractor or supplier sends to the property owner at the start of a construction project to preserve their lien rights. But the specific requirements, deadlines, recipients, and consequences vary significantly by state. Understanding the distinction matters because serving the wrong document or missing the deadline can permanently eliminate your right to file a mechanic's lien.

What Is a Preliminary Notice

A preliminary notice is a document sent by a subcontractor or supplier to the property owner — and sometimes the GC and construction lender — informing them that the sender is furnishing labor or materials to the project. The purpose is to put the property owner on notice that additional parties beyond the prime contractor are contributing to the project and may have lien rights.

Preliminary notices are required in many states for subcontractors and suppliers who do not have a direct contract with the property owner. Without serving the required notice these parties lose their right to file a mechanic's lien for unpaid work regardless of how much they are owed.

What Is a Notice to Owner

Notice to Owner is the specific term used in Florida for what other states call a preliminary notice. In Florida any subcontractor, sub-subcontractor, materialman, or laborer who does not have a direct contract with the property owner must serve a Notice to Owner within 45 days of first furnishing labor or materials to the project in order to preserve lien rights.

Florida's Notice to Owner requirement is one of the strictest in the country. The notice must be served on the property owner and, if applicable, the construction lender and GC. It must include specific identifying information about the lienor and the services being provided. A defective notice that omits required information may be treated as if no notice was served at all.

How They Compare State by State

California calls its version a 20-Day Preliminary Notice and requires it to be served within 20 days of first furnishing labor or materials. The notice must be served on the property owner, the GC, and the construction lender.

Arizona calls its version a Preliminary 20-Day Notice with the same 20-day deadline. The notice must be served on the owner, the GC, and the construction lender.

Michigan calls its version a Notice of Furnishing and requires it within 20 days of first furnishing labor or materials. In Michigan the notice is served on the GC not the property owner.

Georgia calls its version a Notice to Contractor and requires it within 30 days of first furnishing labor or materials.

Nevada requires a Notice of Right to Lien within 31 days of first furnishing labor or materials.

Florida requires a Notice to Owner within 45 days of first furnishing labor or materials.

Texas does not have a single preliminary notice requirement but has a complex system of monthly notices that must be served on the GC and owner on specific dates each month to preserve lien rights for that month's work.

The Critical Deadline

In every state that requires a preliminary notice the deadline runs from the first day you furnish labor or materials — not from the date you signed the contract or the date you received your subcontract. If you start work on a project and wait two weeks to serve the notice you have already lost lien rights for those first two weeks of work.

The practical implication is that preliminary notice should be served on day one of every project in every state that requires it, before you know whether payment will become an issue. Waiting to see whether problems arise and then serving notice is too late.

What Happens If You Miss the Deadline

Missing the preliminary notice deadline in a state that requires it permanently eliminates your right to file a mechanic's lien for work performed before the notice was served. In some states missing the deadline entirely eliminates all lien rights for the project regardless of work performed afterward.

This consequence is severe and often surprises subcontractors who believe their work quality and clear payment terms are enough protection. In states with strict preliminary notice requirements they are not. The notice is a mandatory procedural step and missing it is not excused by any other circumstance.

Who Needs to Serve a Preliminary Notice

Preliminary notice requirements typically apply to parties who do not have a direct contract with the property owner — subcontractors, sub-subcontractors, material suppliers, and equipment rental companies. Prime contractors who have a direct contract with the owner are generally not required to serve a preliminary notice to preserve their lien rights.

Check the specific requirements for each state where you work. The rules about who must serve notice, who must receive it, and what the notice must contain vary enough from state to state that relying on general knowledge is risky.

The Bottom Line

Preliminary notice and Notice to Owner describe the same essential document — a written notification that puts the property owner on notice that you are furnishing labor or materials and preserving your right to file a lien if you are not paid. The specific name, deadline, recipients, and content requirements vary by state. Serve the required notice on every project in every state that requires it, on day one, before you know whether payment will become an issue. By the time problems arise it is usually too late to fix a missed notice deadline.

Frequently Asked Questions

What is the difference between a preliminary notice and a Notice to Owner?

They describe the same concept — a written notification served on the property owner to preserve lien rights — but Notice to Owner is the specific term used in Florida. Other states use different names including Preliminary Notice, Notice of Furnishing, and Notice to Contractor.

In most states subcontractors, sub-subcontractors, material suppliers, and equipment rental companies who do not have a direct contract with the property owner must serve a preliminary notice to preserve lien rights. Prime contractors with direct owner contracts are generally exempt.

What happens if you miss the preliminary notice deadline?

You permanently lose lien rights for work performed before the notice was served. In some states missing the deadline entirely eliminates all lien rights on the project.

How long do you have to serve a preliminary notice?

It depends on the state. California and Arizona require notice within 20 days of first furnishing. Michigan within 20 days. Georgia within 30 days. Nevada within 31 days. Florida within 45 days.
