Mechanics Lien Enforcement & Foreclosure Procedures

A Mechanics Lien is a constitutionally protected security interest in real property granted to contractors, subcontractors, material suppliers, equipment lessors, and design professionals who provide labor or materials to improve real property in California (California Constitution, Article XIV, Section 3; California Civil Code Sections 8400–8494).

When properly recorded, a mechanics lien creates a legal cloud on the property title, preventing the owner from selling, refinancing, or obtaining clear title until the underlying debt is satisfied, resolved, or bonded off.


Recording Deadlines: Direct Contractors vs. Subcontractors

The statutory timeframe for recording a Claim of Lien at the County Recorder's Office depends on whether the owner records an official Notice of Completion or Notice of Cessation.

Claimant TypeStandard Deadline (No Notice Recorded)Shortened Deadline (Valid Notice of Completion Recorded)Shortened Deadline (Notice of Cessation Recorded)
Direct Contractor (Prime)90 Days after completion60 Days after recordation60 Days after recordation
Subcontractors & Suppliers90 Days after completion30 Days after recordation30 Days after recordation

What Constitutes "Completion"? (Civil Code § 8180)

Under Civil Code Section 8180, completion of a work of improvement occurs upon any of the following events:

  1. Actual Completion: The physical work of improvement is finished.
  2. Occupation/Use + Cessation of Labor: The owner occupies or uses the work of improvement, accompanied by a complete cessation of labor.
  3. 60-Day Continuous Cessation: Labor on the jobsite stops continuously for 60 calendar days.
  4. Acceptance: Public entity accepts the work of improvement (for public works).

Notice of Completion Rules & The 10-Day Service Requirement

To shorten the lien recording period, the property owner must record a Notice of Completion in the County Recorder's office within 15 calendar days after actual completion (Civil Code Section 8182).

Crucially, under Civil Code Section 8190, the owner MUST serve a copy of the recorded Notice of Completion on the direct contractor and all sub-tier claimants who served a valid Preliminary Notice within 10 calendar days of recordation. If the owner fails to serve this notice within 10 days, the shortened 30-day (subcontractor) and 60-day (direct contractor) recording deadlines DO NOT APPLY, and claimants retain the full 90-day recording window from project completion!


Pre-Recording Service of Lien (Civil Code § 8416)

Before or simultaneously with recording the Claim of Lien in the County Recorder's office, the claimant MUST serve a copy of the Claim of Lien accompanied by a signed Proof of Service Affidavit on the property owner via registered mail, certified mail, or first-class mail with certificate of mailing.

Under Civil Code Section 8416(e), failure to serve a copy of the Claim of Lien on the property owner as required renders the mechanics lien completely void and unenforceable.


The 90-Day Lawsuit Filing Window (Civil Code § 8460)

A recorded mechanics lien does not remain on real property title forever. Under Civil Code Section 8460:

  • The lien claimant MUST file a judicial foreclosure lawsuit in Superior Court within 90 calendar days after recording the Claim of Lien.
  • Credit Extension Exception: If the owner and lien claimant execute a written extension of credit before the 90 days expire and record notice of credit, the lawsuit deadline can be extended up to 1 year from project completion.
  • Automatic Voiding: If no foreclosure lawsuit is filed within 90 days (and no credit extension is recorded), the mechanics lien automatically expires and becomes null and void.
Lien Enforcement Lifecycle:
[Work Complete] --> [Record Claim of Lien] --> [File Foreclosure Lawsuit] --> [Record Lis Pendens]
                    (Within 30/60/90 Days)      (Within 90 Days of Lien)    (Within 20 Days of Suit)

Lambert Petition to Release Expired Lien (Civil Code § 8480)

If a lien claimant allows a lien to expire without filing a lawsuit and refuses to record a voluntary release after receiving a 10-day written demand from the owner, the owner can petition the Superior Court for an order expunging the void lien under Civil Code Section 8480 (commonly called a Lambert Petition). The court must award the prevailing property owner mandatory attorney fees.


Notice of Pendency of Action (Lis Pendens - Civil Code § 8461)

Within 20 calendar days after filing a mechanics lien foreclosure lawsuit in Superior Court, the plaintiff/claimant MUST record a Notice of Pendency of Action (Lis Pendens) in the County Recorder's office (Civil Code Section 8461).

The Lis Pendens puts prospective buyers, lenders, and encumbrancers on legal notice that title to the real property is subject to active litigation. Failure to record a Lis Pendens risks losing lien priority against subsequent bona fide purchasers or mortgage lenders.


Lien Priority & The Visible Commencement Rule (Civil Code § 8450)

Under Civil Code Section 8450, mechanics liens take priority over any mortgage, deed of trust, or other encumbrance that attaches to the property after the commencement of the work of improvement.

Under California's "relation back" doctrine, all mechanics liens on a project relate back to the exact date that visible physical work first commenced on the site (e.g., clearing, grading, excavation, or delivery of building materials). Even if a subcontractor performs framing work months later, their mechanics lien priority dates back to the very first day site work began, giving mechanics liens priority over construction loans recorded after work started.


Mechanics Lien Release Bonds (Civil Code § 8424)

If a property owner or direct contractor wants to remove a mechanics lien from property title (e.g., to sell the property, refinance, or obtain progress payments), they may purchase and record a Mechanics Lien Release Bond under Civil Code Section 8424.

  • Bond Amount: Must equal 125% of the amount of the claim of lien.
  • Legal Effect: Upon recordation of a valid 125% release bond, the real property is immediately unencumbered, and the claimant's lien rights transfer from the real estate to the surety bond.
