Understanding California Mechanics Liens
What is a Mechanics Lien?
A mechanics lien is a legal claim against property under California Civil Code §8200-8494. It secures payment for labor, materials, equipment, or services provided to improve real property. Contractors, subcontractors, material suppliers, equipment renters, and laborers can file liens if not paid for their work.
Key features of mechanics liens:
- Provides security interest in the property
- Effective against property owner and lenders
- Can be foreclosed to force property sale
- Can accrue interest and attorney fees
- Statutory rates and strict procedures apply
Preliminary Notice Requirements
Preliminary notice must be served within 20 days of first furnishing labor, materials, or services under California Civil Code §8200. Failure to serve preliminary notice can eliminate lien rights for non-construction laborers and some suppliers.
The notice must be served on:
- Property owner
- Construction contractor
- Surety (if payment bond exists)
Service method: Personal delivery, certified mail, or email (with confirmation).
Filing Deadlines
The mechanics lien must be recorded within strict deadlines after project completion:
- 90 days after completion or cessation of work (default)
- 90 days after notice of completion is recorded
- 60 days after notice of cessation is recorded
These are hard deadlines. Missing the deadline eliminates lien rights entirely. California courts strictly enforce these requirements.
Lien Foreclosure
After recording a mechanics lien, you have 90 days to file a foreclosure action under California Civil Code §8480. Foreclosure converts the lien into a judgment and allows forced sale of the property.
Key points:
- Must file court action within 90 days of recording
- Failure to file within 90 days eliminates lien
- Foreclosure is often necessary to force payment
- Judicial sale converts lien to proceeds
- Attorney fees may be recoverable in foreclosure
Stop Payment Notices
A stop payment notice under California Civil Code §8502 stops progress payments from the project owner to the contractor. This forces the owner to hold funds to satisfy the claim.
Timing requirements:
- Must be served before mechanics lien deadline expires
- Typically within 90 days of last work date
- Must be served on project owner and contractor
- Owner must then hold sufficient funds
Civil Code §8200 vs. §8450
§8200: General preliminary notice requirements apply to all claimants furnishing labor, materials, or services.
§8450: Alternative notice procedure available for contractors and subcontractors on private projects only. Requires specific statutory form and timing.
Both procedures must be strictly followed. Improper notice can eliminate lien rights. Requirements vary by claimant type and project type.
