Preliminary Notice Lien Waivers Pricing FAQ Create Notice

The California Lien Cycle

Everything that happens between Day 1 on the job and the day your lien rights are finally closed out.

Most guides cover one piece of this. Preliminary notice over here. Lien waivers over there. Mechanics lien filing somewhere else. Nobody ever puts the whole thing in one place and explains how it flows together — what triggers what, what you can’t do without what, and where people get into trouble.

This is that article.

If you are a subcontractor, supplier, or bookkeeper managing the payment documentation for a California construction project, this is the map. Start to finish.

The Big Picture First

The California lien cycle has five phases, and they happen in order. You cannot skip phases. Each one is a prerequisite for the next.

Phase 1 → Preliminary Notice (Day 1–20) Phase 2 → Progress Payments + Conditional Waivers (ongoing) Phase 3 → Final Payment + Unconditional Waiver (project end) Phase 4 → Mechanics Lien (if unpaid — optional / enforcement) Phase 5 → Lien Release (project closed out)

If everything goes right — work is done, invoices are paid, waivers are exchanged properly — you never reach Phase 4. The cycle closes cleanly at Phase 3. Most projects do exactly that.

Phase 4 only comes into play when someone doesn’t pay. And Phase 5 closes out the lien whether it was filed or not.

Phase 1

The Preliminary Notice

What it is

A statutory notice served on the owner, direct contractor, and construction lender (if any) informing them that you are furnishing labor, materials, or equipment on the project.

When

Within 20 days of your first date of furnishing. California Civil Code §8200.

Who must send it

Any subcontractor, material supplier, or equipment lessor who does not have a direct contract with the property owner. If you are a direct contractor (GC) and there is a lender on the job, you must serve notice on the lender. On public works, the requirements are slightly different — see the Subcontractor Lien Rights guide.

What happens if you don’t

You lose your right to file a mechanics lien, issue a stop payment notice, or make a claim against a payment bond. All three remedies gone. You are left with breach of contract only — a slower, more expensive path with no leverage over the property itself.

What the notice does NOT do

It is not a lien. It does not cloud the title. It does not harm the owner’s ability to sell, refinance, or close escrow. It is purely informational — it puts the right people on notice that you exist and are owed money if the job goes sideways.

The retroactive window

A late preliminary notice still covers you — but only for work performed in the 20 days before the notice was served, and everything going forward. Work performed before that window is unprotected. This is why filing on Day 1 matters.

Phase 2

Progress Payments and Conditional Waivers

What it is

On most California construction projects, payment is made in draws — progress payments tied to milestones or billing periods. Each time a payment is made, a lien waiver is exchanged.

The four California waiver forms

California Civil Code §§8132–8138 defines four statutory forms. They are not suggestions — these are the only valid forms for California projects. Using a non-statutory form can create disputes about enforceability.

  1. Conditional Waiver on Progress Payment (§8132) — You give this when requesting a progress payment. It says: “When I receive this payment and it clears, my lien rights for this billing period are released.” It is conditional on payment actually being made and clearing.
  2. Unconditional Waiver on Progress Payment (§8134) — Signed after the progress payment has been received and cleared. This permanently closes out your lien rights for that payment period.
  3. Conditional Waiver on Final Payment (§8136) — Same concept as the conditional progress waiver, but for the final payment on the project.
  4. Unconditional Waiver on Final Payment (§8138) — Signed after final payment has been received and cleared. This fully and permanently closes out your lien rights for the entire project.

The critical rule on conditionals

A conditional waiver does not release your rights until payment is made. Do not sign an unconditional waiver in exchange for a check that has not cleared. This is the most common lien waiver mistake in California. A check that bounces after you signed an unconditional is a payment problem you have made significantly worse. See the Lien Waiver vs Lien Release guide for more detail on waiver types.

The flow for each billing period

You invoice → GC/owner sends check → You send Conditional Progress Waiver → Check clears → You send Unconditional Progress Waiver → Repeat next billing period

Phase 3

Final Payment and Close-Out

The flow

Work complete → Final invoice submitted → GC/owner sends final payment → You send Conditional Final Waiver → Final payment clears → You send Unconditional Final Waiver → Lien cycle closed

What “complete” means

Your portion of the work is complete — not necessarily the whole project. Your lien deadline clock runs from your last date of furnishing, not the project completion date.

The 90-day deadline

After your last date of furnishing, you have 90 days to record a mechanics lien if you need to. If the owner records a Notice of Completion or Notice of Cessation, that window compresses to 30 days for subcontractors and suppliers. This is why you want to be watching for completion notices — the deadline can move without warning.

If you receive a Notice of Completion

Act immediately. You have 30 days. Do not assume you have 90.

Phase 4 — Only If Unpaid

Mechanics Lien

What it is

A recorded claim against the title of the property, asserting that you are owed money for work or materials furnished to that property. This is an enforcement mechanism — not a routine step.

Prerequisites

You must have served a valid preliminary notice (Phase 1). Without it, the lien is invalid and unenforceable.

How to file

Record a Claim of Mechanics Lien with the county recorder in the county where the project is located. The lien must contain specific statutory information — claimant name, owner name, property description, amount claimed, and a statement of the claimant’s demand. California Civil Code §8416.

The enforcement window

After recording, you have 90 days to file a lawsuit to enforce the lien or it expires automatically. A lien that expires without enforcement has no legal effect — the title clears.

The practical leverage

Most mechanics liens never go to trial. The lien clouds the title, which means the owner cannot sell, refinance, or close escrow without resolving it. This leverage is often enough to get a payment conversation moving very quickly. The lien is the threat that makes payment happen.

Stop payment notice

A related but separate remedy. A stop payment notice is served on the construction lender, not the owner, and instructs the lender to withhold funds from the GC until your claim is resolved. If there is a lender on the job, this can be more powerful than the mechanics lien because it goes directly to the money source. Also requires a valid preliminary notice.

Phase 5

Lien Release

What it is

Once a mechanics lien has been recorded, it needs to be formally released when the dispute is resolved and payment is made. A lien release removes the cloud from the title.

When it’s required

Only when a mechanics lien has actually been recorded. If you went through Phases 1–3 cleanly with properly exchanged waivers, no separate lien release is needed — the unconditional final waiver handles it.

How to release

Record a Release of Mechanics Lien with the same county recorder where the lien was filed. California Civil Code §8120.

What happens if you don’t release it

The lien stays on title. In California, if you willfully fail to release a lien within 10 days of written demand after the dispute is resolved, you can be liable for damages and attorney fees. Civil Code §8488.

The Full Cycle — One View

When everything goes right

Day 1 — Work begins Day 1–20 — Preliminary Notice served [Ongoing] — Work performed, invoices submitted [Each pay period] — Conditional Progress Waiver sent → Payment received and cleared → Unconditional Progress Waiver sent [Project end] — Final invoice submitted [Final payment] — Conditional Final Waiver sent → Payment clears → Unconditional Final Waiver sent [Done] — Lien cycle closed. No lien recorded. No release needed.

When someone doesn’t pay

Day 1 — Work begins Day 1–20 — Preliminary Notice served [Ongoing] — Conditional/Unconditional Progress Waivers exchanged [Payment stops] — Invoice ignored, GC unresponsive [Within 90 days of last furnishing] — Mechanics Lien recorded [Owner notified] — Title clouded, escrow blocked [Resolution] — Payment made [Within 10 days of demand] — Lien Release recorded [Done] — Title cleared. You got paid.

Where People Get Into Trouble

Signing the wrong waiver at the wrong time

Signing an unconditional before the check clears. Sending a final waiver when you meant to send a progress waiver. These are the two most common errors and both can permanently waive rights you meant to keep. See the Data Accuracy guide for more on what to do when the wrong document goes out.

Missing the preliminary notice window

The notice has to go out within 20 days of first furnishing. Not 21. Not “we’ll get to it.” The clock starts when work starts — not when you invoice.

Not tracking payment periods

Lien waivers are tied to specific payment periods. A waiver for Period 3 doesn’t cover Period 4. If you have sloppy waiver records and a dispute arises, it becomes very hard to reconstruct which rights you have and haven’t waived.

Missing the lien deadline after a Notice of Completion

You thought you had 90 days. The owner recorded a Notice of Completion on day 15 and you didn’t know. Now you have 30 days and you’re not watching the clock.

Not releasing a resolved lien

The dispute is over, you got paid, you moved on. The lien is still on title. The owner’s attorney sends a demand. Now you owe attorney fees on top of everything else.
