    NOTICE TO PROPERTY OWNER If bills are not paid in full for the labor, services, equipment, or materials furnished or to be furnished, a mechanic's lien leading to the loss, through court foreclosure proceedings, of all or part of your property being so improved may be placed against the property even though you have paid your contractor in full.

    All claimants except direct contractors. This includes subcontractors, material suppliers, equipment lessors, and laborers (if employed by anyone other than the direct contractor).

    Who Is Exempt

    Common Compliance Issues in California

    Disclaimer: The following are frequently cited issues based on statutory requirements. This is NOT legal advice. Consult a California-licensed construction attorney for guidance on your specific situation.

    1Failing to Notify the Construction Lender

    California law requires the Preliminary Notice to be served not just on the owner and direct contractor, but also on the construction lender if one exists.

    Prevention: Always research the property records to identify any construction lenders before sending your notice.

    Ref: Cal. Civ. Code § 8200(e)

    2Missing the 20-Day Window

    While you can file a late notice in California, it only protects the value of labor/materials provided in the 20 days preceding the late notice, forfeiting earlier work.

    Prevention: Establish a strict workflow to send notices within the first 10 days of starting a project.

    Ref: Cal. Civ. Code § 8204(a)

    Frequently Asked Questions

    What happens if I send my California Preliminary Notice late?

    Unlike some states, sending it late does not completely destroy your lien rights. However, it restricts your lien claim to only the labor or materials provided within the 20 days immediately preceding the date the late notice was served, plus any future work.
