Business and Professions Code section 7164

(a)

Notwithstanding Section 7044, every contract and any changes in a contract, between an owner and a contractor, for the construction of a single-family dwelling to be retained by the owner for at least one year shall be evidenced in writing signed by both parties.

(b)

The writing shall contain the following:

(1)

The name, address, and license number of the contractor.

(2)

The approximate dates when the work will begin and be substantially completed.

(3)

A legal description of the location where the work will be done.

(4)

A statement with the heading “Mechanics Lien Warning” as follows:
“MECHANICS LIEN WARNING:
Anyone who helps improve your property, but who is not paid, may record what is called a mechanics lien on your property. A mechanics lien is a claim, like a mortgage or home equity loan, made against your property and recorded with the county recorder.
Even if you pay your contractor in full, unpaid subcontractors, suppliers, and laborers who helped to improve your property may record mechanics liens and sue you in court to foreclose the lien. If a court finds the lien is valid, you could be forced to pay twice or have a court officer sell your home to pay the lien. Liens can also affect your credit.
To preserve their right to record a lien, each subcontractor and material supplier must provide you with a document called a ‘Preliminary Notice.’ This notice is not a lien. The purpose of the notice is to let you know that the person who sends you the notice has the right to record a lien on your property if he or she is not paid.
BE CAREFUL. The Preliminary Notice can be sent up to 20 days after the subcontractor starts work or the supplier provides material. This can be a big problem if you pay your contractor before you have received the Preliminary Notices.
You will not get Preliminary Notices from your prime contractor or other persons you contract with directly or from laborers who work on your project. The law assumes that you already know they are improving your property.
PROTECT YOURSELF FROM LIENS. You can protect yourself from liens by getting a list from your contractor of all the subcontractors and material suppliers that work on your project. Find out from your contractor when these subcontractors started work and when these suppliers delivered goods or materials. Then wait 20 days, paying attention to the Preliminary Notices you receive.
PAY WITH JOINT CHECKS. One way to protect yourself is to pay with a joint check. When your contractor tells you it is time to pay for the work of a subcontractor or supplier who has provided you with a Preliminary Notice, write a joint check payable to both the contractor and the subcontractor or material supplier.
For other ways to prevent liens, visit CSLB’s Web site at www.cslb.ca.gov or call CSLB at 800-321-CSLB (2752).
REMEMBER, IF YOU DO NOTHING, YOU RISK HAVING A LIEN PLACED ON YOUR HOME. This can mean that you may have to pay twice, or face the forced sale of your home to pay what you owe.”

(5)

(A)A statement prepared by the board through regulation that emphasizes the value of commercial general liability insurance and encourages the owner to verify the contractor’s insurance coverage and status.

(B)

A check box indicating whether or not the contractor carries commercial general liability insurance, and if that is the case, the name and the telephone number of the insurer.

(c)

The writing may also contain other matters agreed to by the parties to the contract. The writing shall be legible and shall clearly describe any other document which is to be incorporated into the contract. Prior to commencement of any work, the owner shall be furnished a copy of the written agreement, signed by the contractor. The provisions of this section are not exclusive and do not relieve the contractor from compliance with all other applicable provisions of law.

(d)

Every contract subject to the provisions of this section shall contain, in close proximity to the signatures of the owner and contractor, a notice in at least 10-point boldface type or in all capital letters, stating that the owner has the right to require the contractor to have a performance and payment bond and that the expense of the bond may be borne by the owner.

(e)

The requirements in paragraph (5) of subdivision (b) shall become operative three months after the board adopts the regulations referenced in subparagraph (A) of paragraph (5) of subdivision (b).

(f)

This section shall become operative on January 1, 2006.
