In California, there must be a written contract for all home improvement projects over $500 in combined labor and materials costs. That contract must include specific information about your rights and responsibilities.
One of the more common reasons for CSLB discipline is violation of California Business and Professions Code Section 7159.5(a)(3), accepting an excessive downpayment on a home improvement contract.
The contract should describe, in detail, the products to be used and how the work will be performed, i.e., size, color, who will be doing what work, amounts of materials provided, manufacturer model number, etc. There must be a detailed, written payment schedule in the contract.
Contractors operating in California must be licensed by the Contractors State License Board. The legislature requires this in order to protect the public from unscrupulous and unsafe contractors. Under California Business and Professions Code Section 7028 BPC it is illegal to engage in contracting without a license.
