# Supplier Lien Rights: A Material Supplier's Guide to Getting Paid

Last updated: July 2025

Material suppliers have the legal right to file a mechanics lien against a property if they go unpaid for materials delivered to a construction project — but that right depends entirely on following the correct preliminary notice procedure in your state before the deadline. Most states require suppliers to serve a preliminary notice within 20 to 45 days of first delivery to preserve lien rights, with statutes such as [Cal. Civ. Code § 8200](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV&sectionNum=8200.) (20 days in California), [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(a) (45 days in Florida), and [Ariz. Rev. Stat. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm) (20 days in Arizona) governing the requirement. Suppliers who miss this window cannot file a valid lien — and lose their most powerful legal leverage to compel payment. The lien itself does not need to be filed immediately; the preliminary notice is the critical first step that keeps your options open.

## Do Material Suppliers Have Lien Rights?

Yes — material suppliers have mechanics lien rights in every U.S. state, but the scope of those rights depends on your position in the payment chain and whether you served the required preliminary notice on time. A supplier who provides lumber, pipe, fixtures, roofing materials, or any other materials incorporated into a construction project is a protected party under most state mechanics lien statutes. You do not need a direct contract with the property owner to have lien rights. What you do need is proper notice.

The key distinction that trips up suppliers is the difference between a supplier to a general contractor and a supplier to a subcontractor. In many states, a supplier two or more tiers removed from the owner faces stricter or additional notice requirements. In Texas, for example, a supplier to a first-tier subcontractor must serve a notice by the 15th of the second month following each month of delivery under Tex. Prop. Code § 53.056, while a supplier to a second-tier subcontractor (a "sub-sub" supplier) has different obligations under § 53.057. Know your tier before you assume you are covered.

## What Is a Preliminary Notice and Why Does a Supplier Need One?

A preliminary notice — also called a Notice to Owner, Notice to Contractor, or Notice of Right to Lien depending on the state — is a written document served early in a project that informs the property owner, general contractor, and sometimes the construction lender that your company is providing materials to their project. It is not a lien. It is the prerequisite that keeps lien rights alive.

Without a timely preliminary notice, a supplier lien filing will be invalid in most states. The notice serves a practical purpose beyond legal compliance: it puts the owner on notice that you exist on the job, which often accelerates payment on its own. Owners who know a supplier can lien their property are far more motivated to ensure the GC or sub pays their bills. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days — preliminary notices are one of the few tools a supplier controls unilaterally to improve that outcome.

## What Are the Preliminary Notice Deadlines for Suppliers by State?

Deadlines vary by state, and missing them by even one day can void your lien rights entirely. Here are the key deadlines for states where LienFlash operates:

**California:** Serve within 20 days of first furnishing materials ([Cal. Civ. Code § 8200](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV&sectionNum=8200.)). Late service is allowed but only preserves rights for materials delivered in the 20 days before service — everything before that date is unprotected.

**Florida:** Serve a Notice to Owner within 45 days of first furnishing materials ([Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(a)). Florida is strict — there is no partial protection for late service. Miss the 45-day window and your lien rights are gone on that project.

**Arizona:** Serve within 20 days of first furnishing materials ([Ariz. Rev. Stat. § 33-992.01](https://www.azleg.gov/ars/33/00992-01.htm)). Arizona allows late preliminary notices, but protection only covers materials delivered in the 20 days before service, identical to California's rule.

**Nevada:** Serve a Notice of Right to Lien within 31 days of first furnishing materials ([Nev. Rev. Stat. § 108.245](https://www.leg.state.nv.us/NRS/NRS-108.html#NRS108Sec245)). Nevada's window is one of the shorter absolute deadlines in the western states.

**Washington:** Serve within 60 days of first furnishing materials ([Wash. Rev. Code § 60.04.031](https://app.leg.wa.gov/RCW/default.aspx?cite=60.04.031)). Washington gives suppliers more time, but the 60-day clock is still a hard deadline.

**Oregon:** Serve within 8 business days of first furnishing materials ([Or. Rev. Stat. § 87.021](https://oregon.public.law/statutes/ors_87.021)). Oregon has one of the shortest windows in the country — suppliers shipping materials to Oregon jobs need an immediate notice process in place.

**Texas:** The notice requirement depends on your tier in the contract chain and uses monthly delivery cycles tied to the 15th of the second month following delivery, under Tex. Prop. Code §§ 53.056–53.057. Texas does not require a single upfront preliminary notice — it requires ongoing monthly notices.

**New Mexico:** Serve a preliminary notice within 60 days of first furnishing under [NMSA § 48-2-2.1](https://law.justia.com/codes/new-mexico/chapter-48/article-2/section-48-2-2-1/).

The fastest way to confirm your exact deadline is to calculate it from your first delivery date.

## Does a Supplier Need a Signed Contract to Have Lien Rights?

No — a supplier does not need a written, signed contract with the property owner to have mechanics lien rights. Lien rights attach to the property itself based on the value of materials furnished, not based on the existence of a direct contractual relationship with the owner. A supplier selling materials on credit to a subcontractor — with nothing but a purchase order and delivery receipt — has lien rights against the property as long as the materials were incorporated into the project and notice was properly served.

This is one of the most underutilized protections in the construction industry. Many suppliers assume that because they never signed anything with the owner, they have no recourse beyond suing their direct customer. That is wrong. The lien statute bypasses the contract chain and attaches the debt to the property. An owner who purchased the property subject to a lien — or allowed a lien to be perfected — has direct financial exposure, which gives the supplier real leverage.

What does matter for lien rights is that the materials were actually delivered to and incorporated into the specific project. A supplier cannot lien a property for materials ordered but never delivered, or for materials that were restocked and never used on the job.

## What Happens After You Serve the Preliminary Notice?

Serving the preliminary notice preserves your lien rights — it does not automatically get you paid, and it does not mean you have filed a lien. After serving notice, you continue supplying materials and invoicing normally. The notice simply ensures that if payment stops, you have the legal foundation to escalate.

If payment is not received after your normal collection efforts, the next step is filing the actual mechanics lien with the county recorder or clerk in the county where the project is located. State deadlines for lien filing vary — in California, a claimant must file within 90 days of project completion ([Cal. Civ. Code § 8414](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV&sectionNum=8414.)); in Florida, within 90 days of the last furnishing ([Fla. Stat. § 713.08](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.08.html)(5)); in Arizona, within 120 days of project completion ([Ariz. Rev. Stat. § 33-993](https://www.azleg.gov/ars/33/00993.htm)).

After filing the lien, most states require you to initiate a lawsuit to enforce it within a specific timeframe — typically 90 days to one year depending on the state — or the lien expires and becomes unenforceable. The full sequence is: preliminary notice → lien filing → enforcement action. Missing any step breaks the chain.

## What Is a Supplier Lien Waiver and When Should You Sign One?

A lien waiver is a document that releases some or all of your lien rights in exchange for payment. Suppliers are routinely asked to sign lien waivers by general contractors and owners before or after receiving payment. Signing the wrong type — or signing before the check clears — can permanently waive rights you have not yet exercised.

There are four standard lien waiver types:

**Conditional Waiver on Progress Payment:** Waives rights only when you actually receive payment. This is the safest type to sign before a check clears.

**Unconditional Waiver on Progress Payment:** Waives rights immediately upon signing, regardless of whether payment has been received. Do not sign this until the check is in your hand and has cleared.

**Conditional Waiver on Final Payment:** Same as conditional progress, but covers the final payment amount. Still requires payment to become effective.

**Unconditional Waiver on Final Payment:** A complete release of all lien rights. Only sign this when you have confirmed final payment in full.

California standardizes lien waiver forms under Cal. Civ. Code §§ 8132–8138. Other states, including Texas, Florida, and Nevada, have their own statutory or common-law rules governing lien waiver enforceability. If a GC is pushing an unconditional waiver before payment, push back — or refuse to sign until payment clears.

## How Much Does It Cost to Protect Your Lien Rights as a Supplier?

The cost of serving a preliminary notice is small compared to the value it protects. 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. For a material supplier, a single unpaid invoice can wipe out the margin on dozens of delivered jobs.

A preliminary notice through LienFlash costs $24.99 per notice and includes an attorney-reviewed, state-compliant form, USPS Certified Mail with Certificate of Mailing, and a delivery-confirmation PDF. If that $24.99 notice preserves lien rights on a $20,000 materials order that would otherwise go uncollected, the math is straightforward. USPS Certified Mail itself costs $4.85 as the base service fee in 2026 (per USPS Notice 123 pricing), but the form preparation, proper addressing, and documented proof of mailing are where errors happen — and errors void the notice.

Suppliers running multiple jobs simultaneously should consider LienFlash Pro at $49/month, which includes 3 notices per month plus deadline alerts across active jobs, so nothing slips through.

## Frequently Asked Questions

### Can a material supplier file a mechanics lien without a contract with the property owner?

Yes. Mechanics lien rights are statutory, not contractual. A supplier who delivers materials incorporated into a project has lien rights regardless of whether a direct contract exists with the property owner. The requirement is proper delivery, proper preliminary notice, and a valid lien filing within the state deadline.

### What if I delivered materials but they were not incorporated into the project?

Most states require that materials be actually incorporated into the improvement for a lien to attach. Materials that were delivered to the job site but later removed, returned, or never installed may not support a valid lien. Keep delivery receipts and any documentation confirming materials were accepted and used on the project.

### Does a supplier lien affect the property owner even if the owner paid the GC?

Yes, in many states. This is the "double payment" risk that lien statutes create for owners. If an owner paid the GC but the GC did not pay the supplier, the owner may still have a lien on their property. This is why many owners require lien waivers from all subcontractors and suppliers before releasing progress payments.

### What is the difference between a preliminary notice and a mechanics lien?

A preliminary notice is served early in the project — within days or weeks of first furnishing — to preserve lien rights. A mechanics lien is filed with the county after non-payment occurs, creating a formal encumbrance on the property. The preliminary notice is a prerequisite to filing a valid lien in most states.

### Can a supplier lien a project for unpaid freight or delivery charges?

It depends on the state. Most states limit lien rights to the value of materials furnished and incorporated into the project. Delivery and freight charges are covered in some states if they are part of the contract price for materials, but not universally. Verify your state's statute before including freight as a lien amount.

### What happens if I serve the preliminary notice late?

In states like California and Arizona, late service provides partial protection — your lien rights are preserved only for materials delivered in the 20 days before service. In states like Florida, late service is a complete bar to lien rights on that project. There is no partial protection in Florida once the 45-day window closes.

### Do I need to serve a new preliminary notice for each phase of a project?

Generally no — one preliminary notice per project covers all materials furnished on that project, even if delivery spans many months. However, if the project ownership changes, the contract is rebid, or a substantial gap in furnishing occurs, consult the applicable state statute. Some states treat a significant gap as the start of a new furnishing period.

### Can a supplier lien a public project?

Not with a mechanics lien — public property is exempt from private liens in all states. For public projects, the equivalent protection is a payment bond claim under the federal Miller Act (40 U.S.C. § 3133) for federal projects, or the applicable state's Little Miller Act for state and local public projects. Suppliers on public jobs should identify the payment bond and serve a timely bond claim notice instead.
