Legal Question in Construction Law in California

I think the issue will be whether the company is selling goods or doing home improvement contracts. If it is selling goods, it can ask for 100% or whatever. If it is doing home improvements, I believe it can only ask for 10%.

Mr. Whipple is correct. If you are just selling and delivering the cabinets you can require payment up front in full, or any deposit you choose. If you are installing them, you need a contractors license and can only charge 10%. You can, however, charge the cost of the cabinets once they get to the jobsite. You don't have to wait until they are installed.
