You want to enter into a Home Improvement Contract with a client but don’t really like risking your own money to purchase materials.  What can you do?  You can request a downpayment but the downpayment is limited to $1,000 or 10% of the contract price whichever is less.  But the Code Section in relevant part says:

B & P Code Section 7159.5  “This section applies to all home improvement contracts, as defined in Section 7151.2, between an owner or tenant and a contractor, whether a general contractor or a specialty contractor, that is licensed or subject to be licensed pursuant to this chapter with regard to the transaction.

(a) Failure by the licensee or a person subject to be licensed under this chapter, or by their agent or salesperson, to comply with the following provisions is cause for discipline:

(1) The contract shall be in writing and shall include the agreed contract amount in dollars and cents. The contract amount shall include the entire cost of the contract, including profit, labor, and materials, but excluding finance charges.

(2) If there is a separate finance charge between the contractor and the person contracting for home improvement, the finance charge shall be set out separately from the contract amount.

(3) If a downpayment will be charged, the downpayment shall not exceed one thousand dollars ($1,000) or 10 percent of the contract amount, whichever amount is less.

(4) If, in addition to a downpayment, the contract provides for payments to be made prior to completion of the work, the contract shall include a schedule of payments in dollars and cents specifically referencing the amount of work or services to be performed and any materials and equipment to be supplied.

(5) Except for a downpayment, the contractor shall neither request nor accept payment that exceeds the value of the work performed or material delivered.

(6) Upon any payment by the person contracting for home improvement, and prior to any further payment being made, the contractor shall, if requested, obtain and furnish to the person a full and unconditional release from any potential lien claimant claim or mechanics lien authorized pursuant to Sections 8400 and 8404 of the Civil Code for any portion of the work for which payment has been made. The person contracting for home improvement may withhold all further payments until these releases are furnished.

(7) If the contract provides for a payment of a salesperson’s commission out of the contract price, that payment shall be made on a pro rata basis in proportion to the schedule of payments made to the contractor by the disbursing party in accordance with paragraph (4).

(8) A contractor furnishing a performance and payment bond, lien and completion bond, or a bond equivalent or joint control approved by the registrar covering full performance and payment is exempt from paragraphs (3), (4), and (5), and need not include, as part of the contract, the statement regarding the downpayment specified in subparagraph (C) of paragraph (8) of subdivision (d) of Section 7159, the details and statement regarding progress payments specified in paragraph (9) of subdivision (d) of Section 7159, or the Mechanics Lien Warning specified in paragraph (4) of subdivision (e) of Section 7159. A contractor furnishing these bonds, bond equivalents, or a joint control approved by the registrar may accept payment prior to completion. If the contract provides for a contractor to furnish joint control, the contractor shall not have any financial or other interest in the joint control. Notwithstanding any other law, a licensee shall be licensed in this state in an active status for not less than two years prior to submitting an Application for Approval of Blanket Performance and Payment Bond as provided in Section 858.2 of Title 16 of the California Code of Regulations as it read on January 1, 2016.

(b) A violation of paragraph (1), (3), or (5) of subdivision (a) by a licensee or a person subject to be licensed under this chapter, or by their agent or salesperson, is a misdemeanor punishable by a fine of not less than one hundred dollars ($100) nor more than five thousand dollars ($5,000), or by imprisonment in a county jail not exceeding one year, or by both that fine and imprisonment….”

As can be seen if the contractor posts a bond with the CSLB then it can require a downpayment.  Large entities such as Home Depots routinely post the bond so they can request all their money up front.  The bond is usually high and most home remodel contractors can not afford to post it.  Failing to post a bond and seeking payments for work not done or materials not furnished is a violation of number 5 above which subjects a contractor to discipline by the CSLB.
