A $4.2 million hospital renovation in Phoenix wrapped up six months behind schedule. The GC thought every subcontractor was paid. Then three preliminary notices surfaced from suppliers the GC had never contracted with directly -- a concrete reinforcement vendor, a specialty glass fabricator, and an electrical panel distributor. Each had furnished materials to second-tier subcontractors. Each had preserved their lien rights by sending timely preliminary notices. The GC now faced $380,000 in potential mechanics liens on a project that was supposed to be closed out.

This is the scenario preliminary notices are designed to create. Not as an ambush -- as a transparency mechanism. And for general contractors, understanding how preliminary notices work is not optional. It is a fundamental part of managing construction risk.

What Is a Preliminary Notice?

A preliminary notice is a formal written document sent by a party furnishing labor, materials, or equipment to a construction project. It notifies the property owner (and often the general contractor and construction lender) that the sender has a potential right to file a mechanics lien if they are not paid.

The notice does not mean payment is overdue. It does not mean a lien has been filed. It simply establishes a paper trail: "I am providing work or materials on your property, and I am preserving my right to lien if I am not compensated."

Every state that requires preliminary notices has its own name for the document:

State	Name	Statute
California	20-Day Preliminary Notice	Cal. Civ. Code 8200
Florida	Notice to Owner	Fla. Stat. 713.06
Texas	Notice of Contractual Retainage / Fund Trapping Notice	Tex. Prop. Code 53.056
Arizona	Preliminary 20-Day Notice	A.R.S. 33-992.01
Nevada	Notice of Right to Lien	NRS 108.245
Washington	Notice to Owner	RCW 60.04.031
Georgia	Notice of Commencement / Preliminary Notice	O.C.G.A. 44-14-361.5

The terminology changes. The function does not. Every version says: I exist on this project, and I am protecting my payment rights.

Why Preliminary Notices Matter to General Contractors

Most GCs think of preliminary notices as something subcontractors and suppliers worry about. That perspective misses half the picture.

Preliminary notices flow upstream. When a second-tier subcontractor sends a preliminary notice to the property owner, that owner calls the GC. When a material supplier the GC has never heard of sends notice, the GC needs to determine which sub ordered those materials and whether they have been paid.

The GC sits at the center of the notice ecosystem:

As a potential sender. In some states, general contractors must send their own preliminary notice to preserve lien rights. This is less common -- many states exempt parties with a direct contract with the owner -- but it applies in states like California for certain project types.

As a recipient. GCs receive preliminary notices from their subcontractors and from lower-tier parties (sub-subs, suppliers, equipment rental companies). Each notice represents a potential lien claim if payment breaks down.

As a manager. Property owners expect the GC to track who is working on the project and ensure everyone gets paid. Preliminary notices are the early warning system for that obligation.

Who Must Send a Preliminary Notice?

This varies significantly by state, but the general framework follows a pattern based on the party's contractual relationship to the property owner.

Parties Typically Required to Send

Subcontractors -- parties with a contract with the GC but no direct contract with the owner
Sub-subcontractors -- parties contracted by subcontractors
Material suppliers -- companies furnishing materials to any party on the project
Equipment rental companies -- firms providing rented equipment used on the project
Laborers -- in some states, individual laborers must send notice (though this is rare)

Parties Typically Exempt

General contractors -- in most states, the GC has a direct contract with the owner and does not need to send preliminary notice (California, Florida, and Arizona are examples where the direct contractor is exempt)
Parties with direct owner contracts -- design professionals, consultants, and others contracted directly by the owner

The Gray Areas

Some states create exceptions within exceptions. In Texas, the notice framework differs between residential and commercial projects. In New York, the requirements depend on whether the property is in New York City or upstate. In Georgia, the requirements changed significantly in 2019 and some contractors still operate under the old rules.

The safe rule for GCs: assume every subcontractor and supplier on your project is required to send preliminary notice until you confirm otherwise under the applicable state statute.

Preliminary Notice Deadlines by State

Missing the deadline does not always eliminate lien rights entirely, but it almost always reduces the amount recoverable. Some states create a "rolling" notice requirement where the claimant can only lien for work performed within a certain window before the notice was sent.

State	Deadline	Measured From	Consequence of Late Notice
California	20 days	First furnishing labor/materials	Can only lien for work in the 20 days before notice + work after notice
Florida	45 days	First furnishing	Complete loss of lien rights
Arizona	20 days	First furnishing	Can only lien for work in the 20 days before notice + work after notice
Texas	15 days (2nd month)	Each month work is furnished	Loss of lien for unpaid work in prior months
Nevada	31 days	First furnishing	Complete loss of lien rights
Washington	60 days	First furnishing of materials	Reduced recovery window
Michigan	20 days	First furnishing	Can only lien for work in the 20 days before notice + work after notice
Georgia	30 days	Filing of Notice of Commencement	Loss of lien rights

Critical distinction: "first furnishing" means the first day the claimant provides any labor or materials to the project. Not the contract signing date. Not the purchase order date. The day boots hit the ground or materials arrive on site.

What Information Must a Preliminary Notice Contain?

While specific requirements vary by state, most preliminary notices must include:

Project identification -- the property address and a description of the project
Owner information -- the name and address of the property owner
General contractor information -- the name and address of the GC
Claimant information -- the name, address, and contact details of the party sending the notice
Description of materials or services -- a general description of the labor, materials, or equipment being furnished
Estimated value -- some states require an estimated dollar amount of the labor or materials to be furnished
Contract information -- identification of the party with whom the claimant has a direct contract

Some states provide statutory forms that must be used exactly as written. California's form under Civil Code Section 8202 is prescriptive. Other states allow any format that includes the required information.

How GCs Should Manage Incoming Preliminary Notices

Receiving a preliminary notice is not a threat. It is information. Here is how to use it.

Build a Notice Register

Create a centralized log of every preliminary notice received on each project. The register should track:

Date received
Party sending the notice
Party they contracted with (your sub, a sub-sub, a supplier)
Estimated value of materials or services
Whether the party appears on your approved subcontractor or supplier list
Payment status of the contracting party

Cross-Reference Against Your Subcontractor List

When a preliminary notice arrives from a party you do not recognize, trace the chain. Which of your subcontractors hired them? Is that subcontractor current on payments to their own vendors? A notice from an unknown material supplier to your electrical subcontractor is an early indicator of cash flow problems in that sub's operation.

Verify Before Paying Through

Many construction contracts include "pay-when-paid" or "pay-if-paid" provisions. When a GC pays a subcontractor, the GC expects the sub to pay their own vendors and laborers. Preliminary notices from lower-tier parties tell you who those vendors are. Before releasing final payment or retainage to a subcontractor, cross-reference the notice register to confirm that all noticed parties have been paid.

Use Notices to Forecast Lien Exposure

Every preliminary notice represents a potential mechanics lien. The total value of outstanding preliminary notices on a project is a rough ceiling on the GC's lien exposure from lower tiers. If you have $2.1 million in active notices and your subcontractor payment records show $1.8 million paid to those parties, your exposure is approximately $300,000.

This is the kind of data that owners, lenders, and sureties want to see.

The GC's Own Preliminary Notice Obligations

While general contractors are exempt from preliminary notice requirements in most states (because they have a direct contract with the owner), there are situations where the GC should send notice anyway:

When the contract is with a lessee, not the owner. If the GC's contract is with a tenant, not the property owner, the GC may need to send notice to the actual property owner to preserve lien rights.

When working on public projects. Public projects replace mechanics liens with bond claims, and the notice requirements for bond claims often differ from private project requirements. The Miller Act (federal) and Little Miller Acts (state) impose their own notice timelines.

When the state does not clearly exempt direct contractors. Some state statutes are ambiguous about whether "direct contractors" includes GCs working under a construction manager. When in doubt, send the notice.

When subcontracting substantially all work. In jurisdictions where the GC acts primarily as a project manager and subcontracts nearly all physical construction, courts have occasionally questioned whether the GC truly has a "direct" relationship with the owner for lien purposes.

Common Preliminary Notice Mistakes That Affect GCs

Mistake 1: Ignoring Received Notices

Some GCs file preliminary notices in a drawer and forget about them. Each notice is a data point about project risk. Ignoring them means losing visibility into which lower-tier parties could potentially lien the project.

Mistake 2: Not Verifying Subcontractor Payment to Noticed Parties

Paying your subcontractor does not extinguish the lien rights of the sub's vendors and suppliers. If a subcontractor collects payment from the GC and fails to pay a material supplier who sent preliminary notice, that supplier can still lien the property.

Mistake 3: Assuming Preliminary Notice Means a Problem

New project managers sometimes panic when a preliminary notice arrives. It is a routine compliance document, not a demand letter. Treat it as information, not as a conflict signal.

Mistake 4: Failing to Require Lien Waivers from Noticed Parties

When a subcontractor requests payment, require conditional lien waivers not just from the sub, but from every lower-tier party that sent a preliminary notice on that project. This is the connection between preliminary notice tracking and lien waiver management.

Mistake 5: Not Tracking Notice Deadlines

If a subcontractor sends a preliminary notice 60 days after first furnishing in a state with a 20-day deadline, that notice may be partially or fully invalid. Knowing the deadlines helps the GC assess actual lien exposure versus theoretical exposure.

Preliminary Notices and Public Projects

Public projects do not have mechanics liens. Government property cannot be liened. Instead, unpaid parties make claims against the payment bond.

The notice requirements for bond claims are different from preliminary notice requirements for private projects:

Federal projects (Miller Act): Subcontractors with a direct contract with the GC do not need to send notice. Sub-subcontractors and suppliers must send written notice to the GC within 90 days of last furnishing.

State public projects (Little Miller Acts): Each state has its own version. Notice deadlines, required recipients, and content requirements vary widely. Some states require notice within 30 days of first furnishing; others require notice within 90 days of last furnishing.

Key point for GCs: On public projects, the GC's payment bond is the target of claims, not the property. This means every bond claim comes out of the GC's bonding capacity. Tracking preliminary notices on public projects is arguably more important than on private projects because the financial impact is direct.

Integrating Preliminary Notice Tracking Into GC Operations

Preliminary notice management should not be a standalone process. It connects to three other critical GC workflows:

1. Subcontractor onboarding. When a new subcontractor begins work, note the "first furnishing" date. This starts the preliminary notice clock for all of that sub's vendors and suppliers.

2. Pay application review. Before approving a subcontractor's pay application, check the notice register. Are there noticed parties who have not submitted lien waivers? Are there noticed amounts that exceed what the sub has billed?

3. Project closeout. Before final payment, ensure that every party who sent a preliminary notice has provided a final unconditional lien waiver. Missing even one creates residual lien exposure.

Frequently Asked Questions

Is a preliminary notice the same as a mechanics lien?

No. A preliminary notice is a prerequisite to filing a mechanics lien, not a lien itself. The notice preserves the right to lien later if payment is not received. Filing a mechanics lien is a separate legal action that occurs after the preliminary notice has been sent and payment remains outstanding.

Do general contractors need to send preliminary notices?

In most states, no. General contractors typically have a direct contract with the property owner, which exempts them from preliminary notice requirements. However, exceptions exist when the GC contracts with a tenant rather than the owner, on public bond claim projects, or in states with ambiguous statutory language about direct contractors.

What should a GC do when receiving a preliminary notice from an unknown party?

Trace the contractual chain. Determine which of your subcontractors hired the party that sent the notice. Contact that subcontractor to confirm the relationship and verify that payment obligations are being met. Log the notice in your project notice register and flag it for follow-up during the next pay application cycle.

Can a subcontractor file a mechanics lien without sending a preliminary notice first?

It depends on the state. In states that require preliminary notice (California, Florida, Arizona, Nevada, and others), failing to send timely notice eliminates or reduces the right to lien. In states that do not require preliminary notice (New York, for example), a subcontractor can file a lien without prior notice, though other procedural requirements must still be met.

How long is a preliminary notice valid?

Most preliminary notices remain valid for the duration of the project or until the claimant's work is complete. Some states require renewal if work spans an extended period. In California, a preliminary notice covers all work performed on the project, not just work performed within a specific window. In Texas, monthly notices may be required to protect lien rights for ongoing work.

Does receiving a preliminary notice increase the GC's financial liability?

Not directly. The notice itself creates no financial obligation. However, it does identify parties who could file mechanics liens if unpaid, which represents potential liability. The GC's actual financial exposure depends on whether the subcontractors in the payment chain are meeting their own payment obligations to the noticed parties.

Stop Managing Preliminary Notices in Spreadsheets

Every preliminary notice your project receives connects to a lien waiver your project needs. Tracking one without the other leaves gaps in your compliance workflow.

SubcontractorAudit links incoming preliminary notices to your lien waiver requirements automatically. When a noticed party has not submitted a waiver, you know before you approve the next pay application -- not after a lien is filed.
