Filing a lien in California requires subcontractors to complete two distinct steps in the right order: serve a 20-day preliminary notice within 20 days of first furnishing labor or materials (Cal. Civ. Code § 8200), and then record a mechanics lien with the county recorder's office no later than 90 days after the notice of completion or cessation is recorded, or 90 days after actual completion of the work if no such notice is recorded (Cal. Civ. Code § 8412). Both requirements apply to subcontractors and material suppliers on private works. Miss the preliminary notice and you lose lien rights entirely. Miss the recording deadline and your lien is void. There is no grace period in either case.
What Is the California Preliminary Notice Requirement for Subcontractors?
California subcontractors who do not have a direct contract with the property owner must serve a 20-day preliminary notice to preserve any future mechanics lien rights — this requirement is non-negotiable under Cal. Civ. Code § 8200.
The notice must be served on three parties:
- The property owner (or reputed owner)
- The general contractor (or reputed general contractor)
- The construction lender, if one exists (Cal. Civ. Code § 8200(a))
Service methods that satisfy the statute include USPS Certified Mail, first-class mail with a certificate of mailing, or personal delivery (Cal. Civ. Code § 8110). Certified Mail is strongly preferred because it creates a timestamped delivery record that holds up in court.
The 20-day clock starts on the day you first furnish labor, materials, or equipment to the job — not the day you sign the contract, not the day work really gets going. Day one of furnishing is day one of your window.
If you serve the notice late, you do not lose all protection. Under Cal. Civ. Code § 8200(b), late service limits your lien rights to labor and materials furnished within the 20 days before service was made. But if you never serve it at all, you have no lien rights, period.

How Long Do You Have to File a Mechanics Lien in California?
The deadline to record a mechanics lien in California depends on whether a notice of completion or cessation was recorded by the owner — and the answer is either 60 days or 90 days (Cal. Civ. Code § 8412).
Here is how it breaks down:
| Scenario | Deadline for Subcontractors |
|---|---|
| Owner records a Notice of Completion or Cessation | 30 days after recording (direct contractors get 60 days) |
| No Notice of Completion or Cessation recorded | 90 days after actual completion of the work |
Wait — the table above reflects the correct statutory split. Under Cal. Civ. Code § 8412, subcontractors have 30 days from the recording of a notice of completion or cessation to record their lien, while the prime contractor gets 60 days. If no such notice is recorded, all claimants — including subcontractors — have 90 days from the date of completion of the work.
"Completion" is defined under Cal. Civ. Code § 8180 as actual completion of the work of improvement, cessation of labor for a continuous 60-day period, acceptance by the owner, or occupation or use by the owner accompanied by cessation of labor.
Missing this deadline means your lien is unenforceable. Courts do not extend it.

What Are the Steps to Record a Mechanics Lien in California?
Recording a mechanics lien in California is a five-step process. Get the sequence right and your lien is valid. Skip a step and it is not.
Step 1: Serve the 20-day preliminary notice. This must happen within 20 days of first furnishing. No preliminary notice means no lien rights, so this step comes before everything else.
Step 2: Complete the mechanics lien claim form. California law requires specific information in the lien claim under Cal. Civ. Code § 8416, including:
- A statement of your demand, after deducting credits and offsets
- The name of the owner or reputed owner
- The name of the person who hired you (your direct contract party)
- A description of the site sufficient for identification
- The claimant's name and address
Step 3: Sign and verify the claim. The claimant or their authorized agent must sign the lien claim under penalty of perjury (Cal. Civ. Code § 8416(b)).
Step 4: Record the lien with the county recorder. Take or mail the completed, signed lien form to the county recorder's office in the county where the project is located. Recording fees vary by county (more on that below).
Step 5: Serve a copy of the recorded lien on the owner. Within 20 days of recording, you must serve a copy of the recorded lien on the property owner (Cal. Civ. Code § 8416(d)). Failure to do this does not void the lien, but it can expose you to damages and attorney's fees if you proceed to enforce it without completing service.
Step 6: File suit to enforce the lien. A mechanics lien is not self-enforcing. You must file a lawsuit to foreclose the lien within 90 days of recording it (Cal. Civ. Code § 8460). If you do not file suit within that window, the lien expires.
Where Do You Get the California Mechanics Lien Form?
There is no single state-issued form that California mandates, but the required content is strictly defined by Cal. Civ. Code § 8416 — and using a form that omits required elements will get your lien rejected or successfully challenged.
You can obtain a compliant form from:
- The California Legislature's Civil Code (the statute itself describes required content)
- County recorder websites (some counties provide sample forms)
- Licensed contractors associations such as the Associated General Contractors of California or the Associated Subcontractors of California
- Lien filing services that use attorney-reviewed, state-compliant templates
The form must include all elements listed under Cal. Civ. Code § 8416 and be notarized or signed under penalty of perjury. Using a generic template pulled from an unverified source is a real risk — one missing element can invalidate the entire lien.
Which County Do You File a Mechanics Lien in California?
You record a mechanics lien in the county where the project property is physically located — not where your business is registered, not where the general contractor is based (Cal. Civ. Code § 8412).
If a project sits on a parcel that crosses county lines, record in every county where the property lies. This is rare but it happens on large infrastructure or development projects.
To find the right recorder's office, use the California Association of County Recorders, Elections Officials, and Clerks (CACREOC) directory or simply search "[county name] county recorder" to reach the official office.
What Does It Cost to Record a Mechanics Lien in California?
Recording fees for a mechanics lien in California are set by each county and are not uniform statewide. Fees are based on the number of pages in the document.
Under California Government Code § 27361, the base recording fee is $15 for the first page and $3 for each additional page in most counties. Some counties add a Building Homes and Jobs Act surcharge of $225 per document (Gov. Code § 27388.1), though mechanics liens are typically exempt from this surcharge — confirm with your specific county recorder.
Realistic cost estimates for a standard mechanics lien:
- Simple lien (1-2 pages): $15–$21 in base recording fees
- With a surcharge (if applicable): Could reach $225+
- Mail-in recording: Some counties charge an additional handling fee
Call your county recorder directly before mailing your lien to confirm current fees and whether they accept mail-in recording. Some counties require in-person filing or have moved to electronic recording systems.
What Happens After You Record the Lien?
Recording the lien is not the finish line — it is the starting gun on a 90-day enforcement clock.
After recording, you have 90 days to file a lawsuit to foreclose the lien in the superior court of the county where the property is located (Cal. Civ. Code § 8460). If the owner disputes the amount, they can petition the court to release the lien by posting a bond equal to 125% of the lien claim (Cal. Civ. Code § 8424).
If the owner pays you in full during this period, you are required to release the lien within 30 days of receiving payment or demand for release (Cal. Civ. Code § 8488). Failing to release a satisfied lien can expose you to damages.
The lien also attaches to the property title, which means it shows up in title searches and can block the owner's ability to sell or refinance. That is your real 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. A recorded lien on title changes that dynamic quickly.
Why Does the Preliminary Notice Matter More Than the Lien Itself?
Most subcontractors focus on the lien deadline and forget that the preliminary notice is the prerequisite that makes the lien possible.
In 2024, preliminary notices were filed on construction projects valued at over $22.7 billion in the United States, according to Lienser via DocJoist Construction Payment Statistics 2026. That number reflects how widely the industry has adopted notice-first practices — because experienced subcontractors know that the notice is where lien rights are made or lost.
If you skip the 20-day preliminary notice and a dispute arises on month three, you have nothing. You cannot retroactively fix a missed notice. You can only negotiate from a position of weakness, sue on the contract (which is slower and less certain than a lien), or absorb the loss.
The math is straightforward: a single preliminary notice costs $24.99 through LienFlash. If it preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, that is roughly a 60,000% return on the cost of filing — based on LienFlash pricing applied to typical subcontract values.
Frequently Asked Questions
Does a subcontractor always need to serve a 20-day preliminary notice in California?
On private works, yes — subcontractors who do not have a direct contract with the property owner must serve a 20-day preliminary notice to preserve mechanics lien rights under Cal. Civ. Code § 8200. On public works, a different notice requirement applies (a stop payment notice). There is no preliminary notice requirement for the prime contractor on private works, but subcontractors and suppliers at every tier below the prime must serve it.
What if I started work more than 20 days ago and never sent a preliminary notice?
Send it now. Under Cal. Civ. Code § 8200(b), late service still protects you for labor and materials furnished in the 20 days before the notice is served. You lose coverage for everything before that window, but partial lien rights are better than none. Do not wait any longer.
Can I serve the preliminary notice by email?
No. California Civil Code § 8110 does not authorize email service for preliminary notices. Accepted methods are USPS Certified Mail, first-class mail with a certificate of mailing, or personal delivery. Email does not preserve your rights even if the recipient confirms receipt.
How do I find the property owner's address to serve the notice?
Start with the county assessor's office — property ownership records are public and searchable online in most California counties. You can also use the building permit application, which typically lists the owner. If the owner cannot be identified after reasonable diligence, Cal. Civ. Code § 8102 allows you to serve the "reputed owner" and document your efforts.
Does recording a mechanics lien guarantee I get paid?
No. A recorded lien gives you a security interest in the property and the leverage to force payment or file suit. To collect, you must either reach a settlement or file a lawsuit to foreclose the lien within 90 days of recording (Cal. Civ. Code § 8460). The lien itself does not automatically transfer funds to you.
What is the deadline if the owner records a notice of completion the same day the job finishes?
Subcontractors have 30 days from the date the notice of completion is recorded to record their mechanics lien (Cal. Civ. Code § 8412). That clock starts on the recording date, not the mailing date or the date you receive notice. Monitor the county recorder's records for notices of completion on your active jobs.
Can a mechanics lien be filed on a rental property or commercial building, not just residential?
Yes. California mechanics lien rights apply to any private works project — residential, commercial, industrial, or mixed-use. The same preliminary notice and lien recording requirements under Cal. Civ. Code §§ 8200 and 8412 apply regardless of property type.
What is the difference between a mechanics lien and a stop payment notice in California?
A mechanics lien attaches to the property itself and is used on private works. A stop payment notice is a separate remedy that applies to both private and public works — it directs a construction lender or public entity to withhold funds from the general contractor. On public works where you cannot lien government-owned property, a stop payment notice (Cal. Civ. Code § 8500 et seq.) is often the only effective payment remedy for subcontractors.
