Civ. Code, § 8202

(a) The preliminary notice shall comply with the requirements of Section 8102, and shall also include:

(1) A general description of the work to be provided.

(2) An estimate of the total price of the work provided and to be provided.

(3) The following statement in boldface type:

NOTICE TO PROPERTY OWNER

EVEN THOUGH YOU HAVE PAID YOUR CONTRACTOR IN FULL, if the person or firm that has given you this notice is not paid in full for labor, service, equipment, or material provided or to be provided to your construction project, a lien may be placed on your property. Foreclosure of the lien may lead to loss of all or part of your property. You may wish to protect yourself against this by (1) requiring your contractor to provide a signed release by the person or firm that has given you this notice before making payment to your contractor, or (2) any other method that is appropriate under the circumstances.

This notice is required by law to be served by the undersigned as a statement of your legal rights. This notice is not intended to reflect upon the financial condition of the contractor or the person employed by you on the construction project.

If you record a notice of cessation or completion of your construction project, you must within 10 days after recording, send a copy of the notice of completion to your contractor and the person or firm that has given you this notice. The notice must be sent by registered or certified mail. Failure to send the notice will extend the deadline to record a claim of lien. You are not required to send the notice if you are a residential homeowner of a dwelling containing four or fewer units.

(b) If preliminary notice is given by a subcontractor that has not paid all compensation due to a laborer, the notice shall include the name and address of the laborer and any person or entity described in subdivision (b) of Section 8024 to which payments are due.

(c) If an invoice for material or certified payroll contains the information required by this section and Section 8102, a copy of the invoice or payroll, given in compliance with the requirements of Chapter 2 (commencing with Section 8100) of Title 1, is sufficient.
