Mechanics Lien In California: Laws And Regulations (2026)

Who Can File a Lien in California?

California allows mechanics liens from the following people and entities:

• Direct contractors (also called general contractors)
• Subcontractors who worked under a direct contractor
• Building material suppliers
• Construction equipment lessors
• Laborers
• Architects, engineers, and other designers

California blocks unlicensed contractors from seeking to have mechanics liens enforced in court. While they can technically file liens, the actions would be unenforceable.

Serving the 20-Day Preliminary Notice

A preliminary notice is required for any claimant other than laborers. This notice doesn’t mean a lien has been filed; it simply notifies the property owner or lender that the party reserves the right to file a lien if they haven’t been paid.

The notice must be served within 20 days of starting work or supplying materials. A common mistake arises when prospective claimants misinterpret this requirement to allow filing within 20 days of completion. Claimants who wait this long risk losing the right to file a mechanics lien in California.

California Lien Filing Deadlines

A direct contractor must record the lien before the earlier of the following deadlines:

• 90 days after completion of work
• 60 days after the property owner records a notice of completion or cessation

Other parties, including suppliers and laborers, must record before the earlier of 90 days after completion or 30 days after the owner’s notice of completion.

What the Claim of Lien Must Include

Under California law, a mechanics lien must contain all of the following elements:

• Amount demanded
• Property owner’s name
• Description of work provided
• The claimant’s employer or direct contractor
• Site identification
• Claimant’s address
• Mandatory statement
• Proof of service affidavit signed by the person who delivered the lien

The language for the mandatory statement comes directly from the statute.

Where and How to Record the Lien

Local law determines how to file a mechanics lien. These liens are recorded at the county recorder’s office where the job site is located. The claimant pays the recording fee and provides a signed copy to the clerk.

Enforcing the Lien Within 90 Days

Claimants must commence an action to enforce a lien within 90 days after recording it. The lien expires at the end of this period.

How Property Owners Can Respond

What happens when a mechanics lien is filed? The claimant has a place among other creditors to be paid if the property is sold or refinanced. They can also force a sale and receive payment from the foreclosure proceeds.

Property owners can respond by paying the claimant in full or negotiating a payment plan. If the lien is invalid or defective, the property owner can file a quiet title action to have it removed.
