Notice to Owner: The Document That Saves Subs from Losing Payment
Last updated: July 2025
A notice to owner is a formal written document that subcontractors, material suppliers, and lower-tier contractors must serve on the property owner — and in most states, the general contractor and construction lender — to preserve their right to file a mechanics lien if they go unpaid. Most states require this notice to be served within 20 days of first furnishing labor or materials to the project. Missing the deadline does not always eliminate lien rights entirely, but it limits protection to work performed in the 20 days before late service — or bars lien rights completely, depending on the state. Serving the notice late, or not at all, leaves a subcontractor with no secured legal remedy if the GC or owner refuses to pay.
What Is a Notice to Owner and Who Has to Send One?
A notice to owner (also called a preliminary notice, pre-lien notice, or notice to owner and contractor depending on the state) is a statutory document that puts the property owner on formal notice that you are working on their project and have the right to file a mechanics lien if you are not paid. It is not a lien — it is the prerequisite to filing one.
Who must send it varies by state, but in most jurisdictions the requirement applies to:
- Subcontractors (any tier not in direct contract with the owner)
- Material suppliers furnishing materials to the project
- Equipment lessors renting equipment to the job
- Sub-subcontractors and specialty trades working under a sub
In states like Florida, California, Arizona, Nevada, Washington, and Oregon, a subcontractor who skips this step cannot file a valid mechanics lien — period. General contractors who have a direct contract with the owner are typically exempt from the preliminary notice requirement in most states, because the owner already knows they hired them. But if you are anyone below the GC on the payment chain, assume you need to send it.
What Are the Deadlines for Serving a Notice to Owner?
The most common deadline is 20 days from the date you first furnish labor or materials to the project, though the exact rule depends on your state.
Here is a breakdown of key states:
Florida — Under Fla. Stat. § 713.06(2)(c), subcontractors and suppliers must serve a Notice to Owner no later than 45 days after first furnishing labor, services, or materials. Florida's deadline is longer than most states, but it is a hard cutoff — late service is ineffective, and you lose lien rights entirely for work performed before service.
California — Under Cal. Civ. Code § 8200, subcontractors and suppliers must serve a 20-day preliminary notice within 20 days of first furnishing. Late service limits protection to work performed in the 20 days before service was made. Work performed before that 20-day lookback window is unprotected.
Arizona — Under A.R.S. § 33-992.01, a preliminary 20-day notice must be served within 20 days of first furnishing. Missing the deadline cuts off lien rights for all work furnished before the 20-day window preceding service.
Nevada — Under NRS § 108.245, a notice of right to lien must be served within 31 days of first furnishing labor or materials on residential projects. Commercial projects follow a different notice structure.
Washington — Under RCW § 60.04.031, a notice to owner must be served within 10 days of first furnishing labor or materials on residential projects; for commercial projects, it must be served before or at the time of first furnishing.
Oregon — Under ORS § 87.021, a notice of right to a lien must be served no later than 8 days after first furnishing labor or materials on residential projects and 5 days before filing a lien on commercial projects.
The safest habit: send the notice the same week you mobilize on any job. Waiting until you smell a payment problem is too late.
What Happens If You Don't Send a Notice to Owner?
If you skip the notice, you lose your most powerful legal remedy for non-payment on private work — the mechanics lien. Without a lien, you are an unsecured creditor. That means if the owner or GC refuses to pay, your only options are a collections lawsuit or walking away.
Mechanics liens are powerful because they attach to the property itself. An owner cannot sell or refinance a property with an active lien cloud on the title. That leverage is what gets subcontractors paid — often without ever going to court. No notice to owner means no lien, which means no leverage.
According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. In an environment where slow payment is the norm, not the exception, a mechanics lien is not a last resort — it is a standard business tool. Losing the right to use it because of a missed paperwork deadline is an avoidable catastrophe.
How Do You Properly Serve a Notice to Owner?
Most states require service by one of three methods: certified mail, first-class mail with a certificate of mailing, or personal delivery. Certified mail is the standard — it creates a trackable, timestamped record that proves the notice was sent and received.
Florida requires service by certified mail with return receipt requested, or by personal delivery, under Fla. Stat. § 713.18.
California allows certified mail, first-class mail with certificate of mailing, or personal delivery under Cal. Civ. Code § 8110. For certified mail, the service date is the date of mailing — not the date of receipt.
Arizona requires certified mail or personal service under A.R.S. § 33-992.01.
Washington requires certified or registered mail, or personal delivery, under RCW § 60.04.031.
Keep copies of everything: the completed notice form, your certificate of mailing, and the USPS tracking confirmation. If your lien rights are ever challenged, this paper trail is your proof.
USPS Certified Mail costs $4.85 as the base service fee in 2026, plus standard First-Class Mail postage, according to the USPS Notice 123 Price List. That is a trivial cost compared to what it protects.
Who Do You Send the Notice To?
In most states, the notice must go to multiple parties — not just the property owner.
Florida — The owner and the GC (and the construction lender if one exists on the project) under Fla. Stat. § 713.06(2)(c).
California — The owner, the GC, and the construction lender (if any) under Cal. Civ. Code § 8200(b).
Arizona — The owner, GC, and construction lender under A.R.S. § 33-992.01.
Nevada — The owner and the general contractor under NRS § 108.245.
Obtaining the correct names and addresses is the part where most subs drop the ball. You need the legal name of the property owner (not just the project contact), the GC's legal business name and address, and the lender's information if there is a construction loan. This information is typically available from the building permit, the Notice of Commencement (in Florida), or a county recorder search.
What Information Goes in a Notice to Owner?
A compliant notice to owner includes specific information required by the governing statute. Missing required fields can render the notice defective.
Standard required content across most states:
- Your name, address, and contractor's license number (where required)
- The name and address of the party who hired you (the GC or upper-tier sub)
- A description of the labor, services, or materials you are furnishing
- The legal description or street address of the property
- An estimate of the total price of your contract
- The name and address of the property owner
- The name and address of the GC
- Statutory warning language (some states require verbatim language from the statute)
California requires specific statutory warning language in at least 10-point bold type under Cal. Civ. Code § 8102. Florida requires the notice to include a specific statutory warning statement under Fla. Stat. § 713.06(2)(a). Using a state-compliant, attorney-reviewed template eliminates the risk of serving a technically defective notice.
What Does It Actually Cost to File One — and What Is the ROI?
Filing a notice to owner through a service like LienFlash costs $24.99 per notice and includes an attorney-reviewed, state-compliant form plus USPS Certified Mail delivery with a Certificate of Mailing PDF.
The math on return is straightforward: a single notice that preserves lien rights on a $15,000 subcontract that would otherwise go unpaid represents a 60,000% return on the $24.99 filing cost. On a $75,000 contract, that return exceeds 300,000% (LienFlash pricing applied to typical subcontract values, 2026).
According to Rabbet's 2024 Construction Payments Report, slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending. Subcontractors absorb a disproportionate share of that cost. The preliminary notice is the cheapest insurance policy in construction.
In 2024, preliminary notices were filed on construction projects valued at over $22.7 billion in the United States, according to Lienser data reported by DocJoist. That number reflects how seriously working contractors take their lien rights — and how many projects are in play where protections matter.
Frequently Asked Questions
Is a notice to owner the same as a mechanics lien?
No. A notice to owner is a preliminary document you send at the start of a project to preserve your right to file a mechanics lien later. A mechanics lien is a legal claim recorded against the property title after non-payment occurs. You must typically serve the notice to owner before you can file a valid lien.
What if I miss the notice to owner deadline?
It depends on your state. In Florida, a late notice is completely ineffective — you lose lien rights for all work furnished. In California and Arizona, late service limits protection to work performed in the 20 days before the notice was served. Any work furnished before that window loses lien protection. Serve the notice as early as possible — always before day 20.
Do I need to send a notice to owner on every project?
On every private construction project where you are not in direct contract with the property owner — yes. Most states do not require the notice on public projects (which use payment bonds instead of mechanics liens), but confirm the project type before assuming an exemption applies.
Can I send the notice to owner after I already started work?
Yes, in most states — but you will only protect work performed in the 20 days before service (or 45 days in Florida). Any work you furnished before that lookback window will not be covered by your lien rights. Send it the day you mobilize, not the day a payment problem surfaces.
Does the property owner have to respond to the notice?
No. A notice to owner is not a demand letter — it does not require a response from the owner. It simply puts them on legal notice of your involvement in the project and your right to lien the property if unpaid. Many owners will not even acknowledge it, and that is fine.
What if the GC tells me I don't need to send one?
Ignore that advice. A GC telling a sub not to file a preliminary notice is not doing that sub a favor. The notice does not create conflict — it creates protection. No GC's verbal assurance is enforceable if they stop paying you. Your lien rights are created by statute, not by your GC's goodwill.
How long does it take to serve a notice to owner?
With LienFlash, it takes under two minutes to complete the form, generate a compliant document, and dispatch it via USPS Certified Mail. You receive a Certificate of Mailing PDF as proof of service. USPS First-Class Mail delivers in 1 to 5 business days domestically, with certified mail tracking confirming each step of the delivery chain, per USPS Service Standards (2026).
Can a notice to owner be served electronically?
Most states do not permit electronic service as a substitute for certified mail or personal delivery. Florida, California, Arizona, Washington, and Nevada all require physical service via certified or registered mail, or personal delivery. Some states may accept fax in limited circumstances, but certified mail remains the legally defensible standard in every covered state.
