California Preliminary Construction Notice Mailing Requirements
California law generally requires qualifying claimants to give a preliminary notice to preserve construction-lien rights. The notice may be personally delivered or mailed using a statutory trackable method that includes registered or certified mail.
Trigger
A claimant begins furnishing labor, service, equipment, or materials and needs to preserve payment and lien rights.
Sender
Qualifying subcontractors, material suppliers, equipment lessors, and other claimants
Recipient
The owner or reputed owner, direct contractor, and construction lender when applicable
Timing
Generally within 20 days after first furnishing; a later notice ordinarily reaches only work or materials furnished in the preceding 20 days and afterward.
Mailing method
Personal delivery or mail under Civil Code § 8110, including registered or certified mail, Express Mail, or qualifying overnight delivery.
