How do I file a mechanic's lien in California?

Federal & State Law Editorial TeamLast reviewed: 2026-05-18

California's Mechanics Lien Law is codified at Cal. Civ. Code §§ 8000-9566.

1. Who Can File

General contractors, subcontractors, material suppliers, equipment lessors, design professionals (architects, engineers, surveyors), and laborers who provide work, services, or materials for a work of improvement (Civ. Code §§ 8400, 8430).

2. Preliminary / Pre-Lien Notice

Anyone other than a direct contractor or laborer (wages) must serve a 20-day Preliminary Notice on the owner, direct contractor, and construction lender within 20 days after first furnishing labor or materials (Civ. Code §§ 8200-8216). Late notice limits the lien to work performed within 20 days before notice.

3. Recording the Lien

Record the Mechanics Lien in the county recorder where the property sits. Direct contractors: within 90 days of completion of the work, or 60 days after a Notice of Completion or Cessation is recorded (Civ. Code §§ 8412, 8414). Subs/suppliers: 90 days after completion, 30 days if NOC recorded. Lien must include claimant info, owner, amount, description of work, legal description, and a verified statement (Civ. Code § 8416).

4. Service on Owner

Serve a copy of the recorded lien and a Proof of Service Affidavit on the owner within the same recording window (Civ. Code § 8416(c)).

5. Suit to Foreclose

File foreclosure action within 90 days of recording, or the lien is void and unenforceable (Civ. Code § 8460).

6. Priority

Liens relate back to the commencement of the work of improvement, taking priority over subsequent encumbrances (Civ. Code § 8450).

7. Bond Release

Owner may record a lien release bond for 125% of the claim (Civ. Code § 8424).

8. Homestead / Residential

Owner-occupied single-family dwellings have stricter notice requirements; direct contractors must give a written notice with required statutory language (Civ. Code § 8170).

9. Fraudulent Lien Penalties

Willful overstatement forfeits the entire lien (Civ. Code § 8422); may trigger slander of title and § 17200 unfair-practices liability.
