California's Contractor Deposit Law: The $1,000 Rule

Here's a law most California homeowners have never heard of, even though it's printed on every legal home-improvement contract: a contractor cannot ask for a down payment larger than $1,000 or 10% of the contract price — whichever is less. On a $80,000 kitchen remodel, the maximum legal deposit is $1,000. Not $8,000. One thousand dollars.

What the law actually says

California's home-improvement contract rules (Business & Professions Code § 7159) cap the down payment on residential home-improvement work at $1,000 or 10% of the total price, whichever is less, and require the contract to say so. Violating it is grounds for CSLB discipline and is a misdemeanor under the statute. There are narrow exceptions for contractors who file special bonds or use approved joint-control arrangements — rare enough that you should assume the cap applies.

Why the law exists

Because the classic contracting scam isn't bad work — it's collected money and vanished labor. Big deposits fund the contractor's previous project's debts, or their truck, or their exit. The legislature capped deposits so that money follows work instead of preceding it. That's also the entire philosophy of a good payment schedule: at every point in the project, the value of completed work should equal or exceed what you've paid.

"But materials cost money up front"

The most common justification you'll hear for an illegal deposit — "I need 40% down to order your cabinets." Established contractors have supplier accounts and credit lines; funding their cash flow is not your job, and the law says so explicitly. The legitimate version of this concern is handled inside a proper payment schedule: a milestone payment due on delivery of materials to your site is legal and fair. Money for materials you can see is a payment; money for materials you can't is a loan to a stranger.

What to do when a contractor asks for more

• Name the rule, watch the reaction. "My understanding is California caps the deposit at $1,000 — can we structure this as milestone payments instead?" A professional says yes, because professionals already know the law. Pushback, "everyone does it this way," or a discount for cash-up-front tells you what the next six months would be like — it's one of the clearest contractor red flags there is.
• Restructure, don't just refuse. Offer a legal $1,000 deposit plus an early milestone tied to mobilization or material delivery. You're not trying to starve the contractor — you're keeping payments behind verified progress, which protects both sides.
• If they've already got your money, document everything and know that the CSLB complaint process exists for exactly this. § 7159 violations are enforceable, and licensed contractors have licenses to lose.

The deposit question as a screening tool

I ask about deposits in every contractor interview — not because I need the answer, but because it's the cheapest integrity test available: question #10 on my list. The contractor who quotes the legal cap unprompted has just told you they know the rules and follow them when nobody's checking. That's the person you want holding a hundred thousand dollars of your project. Payment structure — deposits, milestones, retention, lien releases — is the part of contract review where an independent project manager most directly pays for herself.
