California Mechanics Lien Form

Critical: Use Civil Code §8000 — Not §3082 (Repealed)

If you are using a mechanics lien form that cites California Civil Code §3082, §3083, or any section in the §3082–§3267 range — stop. That statute was repealed effective July 1, 2012, when SB 189 took effect. A lien filed on an outdated form citing the old statute may be defective and unenforceable.

California mechanics liens are governed by Civil Code §8000–9566, also known as the California Construction and Design Professionals Lien Statutes. LienForm uses only current, post-2012 statutory citations.

A California mechanics lien is a legal claim against real property under Civil Code §8000–9566 (SB 189, effective July 1, 2012). Subcontractors and material suppliers must first serve a 20-day Preliminary Notice (§8200) within 20 days of first furnishing. The lien itself must be recorded within 90 days of project completion or cessation of work.

A recorded California mechanics lien attaches to the property's title. The owner cannot sell or refinance without first resolving the lien, providing contractors and suppliers with significant leverage to recover unpaid amounts without litigation.

California Mechanics Lien Law — Civil Code §8000 (SB 189)

California's construction lien statutes were completely reorganized and recodified by Senate Bill 189, signed into law in 2010 and effective July 1, 2012. The recodification:

• Repealed the old §3082–§3267 scheme entirely
• Created a new, more organized statutory scheme at Civil Code §8000–9566
• Clarified the Preliminary Notice requirements
• Updated enforcement timelines
• Established clearer form requirements

Structure of the current statute:

Use sections 8200–8216 for private-project preliminary notices, 8412–8414 for completion-based recording periods, 8416 for claim contents and owner service, 8460 for enforcement, and 8480 onward for expired-lien proceedings. General notice requirements begin at section 8100.

20-Day Preliminary Notice — Required for Subs and Suppliers

The 20-day Preliminary Notice (Civ. Code §8200) is the single most important pre-lien requirement in California. Failing to serve it on time significantly limits or eliminates your lien rights.

Who must serve it:

• Subcontractors (no direct contract with owner)
• Material suppliers (supply to GC or subcontractors)
• Equipment lessors (rent equipment to GC or subs)
• Design professionals not in direct contract with the owner
• Any claimant without a direct contract with the property owner

Who is exempt:

• Laborers are exempt. Direct owner-contract claimants still give preliminary notice to the construction lender or reputed construction lender, if any, under section 8200(e).

The 20-day rule: The Preliminary Notice must be served within 20 days of first furnishing labor, materials, or equipment to the project. "First furnishing" means the very first day you provided anything to the project.

What happens if you serve it late: If you serve the Preliminary Notice more than 20 days after first furnishing, your lien rights are retroactively limited. You can only lien for work done within the 20 days before you served the notice and any work done after service. Everything before the 20-day lookback window is unprotected.

Example: You first furnished on January 1. You served the Preliminary Notice on February 1 (31 days late). Your lien rights cover only January 12 onward (the 20 days before February 1) — not January 1–11.

How to serve it: Under Civ. Code §8110, the Preliminary Notice may be served by:

1. First-class mail (with a certificate of mailing)
2. Certified mail
3. Personal delivery with written acknowledgment

Serve it on: (1) the property owner, (2) the general contractor, and (3) the construction lender (if any).

Best practice: Serve the Preliminary Notice on day one of your work or delivery. LienForm generates the Preliminary Notice automatically for all subcontractors and suppliers as part of the California bundle.

Mechanics Lien Deadlines

Once work is complete (or has ceased), the deadline to record a mechanics lien begins running.

For direct contractors (in privity with the owner):

• If the owner records a Notice of Completion or Cessation: you have 60 days from the recording date to file your lien
• If no Notice of Completion or Cessation is recorded: you have 90 days from the actual date of completion or cessation

For subcontractors and suppliers (not in privity with the owner):

• If the owner records a Notice of Completion or Cessation: you have 30 days from the recording date
• If no Notice of Completion or Cessation is recorded: you have 90 days from the actual date of completion or cessation

What triggers "completion"? Under Civ. Code §8180, the completion of a work of improvement occurs on the earliest of:

1. Actual completion of the work
2. Occupation or use by the owner (after substantial completion)
3. Cessation of labor for a continuous 60-day period
4. Recording of a Notice of Cessation after a 30-day labor cessation

This deadline can't be safely auto-calculated from a last-furnishing date alone — it depends on project completion and Notice of Completion status, which LienForm doesn't ask you for. Instead of a countdown, your California bundle shows the applicable rules above and a place to enter the verified deadline yourself once you've confirmed it against county records.

How to Record in California

Recording a California mechanics lien requires strict compliance with the form requirements in Civ. Code §8412–8414.

Required content of the Claim of Lien (Civ. Code §8414):

1. Claimant's name and address
2. The name of the person with whom the claimant contracted (owner or GC)
3. Description of the work furnished (labor, materials, or services)
4. Last date of furnishing
5. Demand (dollar amount owed)
6. Property description (legal description or street address sufficient to identify the property)
7. Owner's name (as known to the claimant)
8. Claimant's signature and date

The "Notice of Mechanic's Lien" warning: California law requires that every recorded lien include a statutory warning block at the top of the document advising the owner of the lien and the 90-day foreclosure deadline. Civ. Code §8416 specifies the exact language. Review the downloaded draft and add or verify the full statutory warning and service declaration before recording; the preparation tool does not establish legal sufficiency.

Serving the owner — no later than the time of recording (Civ. Code §8416):

This is one of the most commonly missed steps, and it is easy to get backwards: California does not give you a window of days after recording to serve the owner. You must serve a copy of the claim of mechanics lien on the owner — or, if the owner cannot be served, the construction lender or original contractor — no later than the time you record it. Service may be personal, or by registered mail, certified mail, or first-class mail accompanied by a certificate of mailing.

If you fail to serve as required, the claim of mechanics lien is unenforceable as a matter of law. Keep a record of when and how you served it, and don't wait until after recording to do it.

LienForm California Bundle — What's Included

For California subcontractors and suppliers, the $24.99 bundle automatically includes:

• Claim of Lien (draft; verify required statutory warning and service declaration)
• 20-day Preliminary Notice (§8200) — auto-included for non-owner-contract claimants
• Deadline confirmation covering the direct-contractor and subcontractor/supplier rules (California's deadline depends on project completion and Notice of Completion status, so this isn't an automatic countdown)
• County recorder filing instructions for your specific county
• Proof of service affidavit for serving the owner no later than recording (§8416)
• Lien release form

For direct contractors, the bundle includes the Claim of Lien, deadline confirmation, recorder instructions, proof of service affidavit, and lien release — no Preliminary Notice needed.

County Recorder Offices

A California mechanics lien must be recorded with the county recorder in the county where the property is located:

Check the property county recorder directly for current fees, addresses, electronic submission options, and formatting. Fees and office details change; no fixed fee estimate is provided here.

Check the property county recorder for the current fee schedule, applicable document surcharges, formatting, and submission procedure. Recording and mailing costs are separate from the preparation fee.
