How much of a deposit can a contractor ask for in California?
Short answer: by law, the down payment on a home improvement job in California cannot be more than $1,000 or 10 percent of the total price, whichever is less. So on a $25,000 remodel, the most they can legally ask up front is $1,000, not $2,500. If someone wants 30 or 50 percent down, that is not how it works here.
The law, in plain numbers
California limits the deposit on a home improvement contract to the lesser of $1,000 or 10 percent of the contract price, not counting finance charges. On a $3,000 job, 10 percent is $300, so the cap is $300. On a $25,000 job, 10 percent is $2,500, so the cap drops to the $1,000 limit. The bigger the job, the more it is the flat $1,000 that controls. This is in the Business and Professions Code and the Contractors State License Board enforces it.
Why "whichever is less" trips people up
People read it as ten percent, with a thousand dollars as some kind of floor. It is the opposite. It is whichever number is smaller. For almost any real remodel, that means the legal deposit tops out at $1,000, even on a job worth tens of thousands. Keep that straight and a "standard 50 percent deposit" line falls apart fast.
What about expensive special-order materials?
This is the usual pushback, and the law does not carve out an exception for it. The deposit is still capped. What a contractor can do is set up progress payments tied to real milestones, like a payment when special materials are delivered to the job. The key is that payments track work and materials actually delivered. The schedule never gets ahead of the job, and the first down payment stays under the cap.
A big deposit demand is a red flag
When a contractor needs a large chunk of your money before they have done anything, that often means cash flow trouble, and sometimes worse. A solid pro runs their business on a payment schedule, not on your deposit. A demand for half down, or for cash up front, is a reason to slow down and check the license and references before you pay a dime.
How to pay so you keep your leverage
Pay the legal down payment, then progress payments as real milestones are hit, and hold the final payment until the punch list is done and any required permit and inspection are signed off. Your leverage is the money you have not paid yet, so never let the payments get ahead of the work. That one habit prevents most of the half-finished-job nightmares.
The law is on your side
The deposit and progress-payment limits are not suggestions. Violating them is a misdemeanor, and you can report a problem to the CSLB. You do not have to be the expert in the room. The rules already favor the homeowner here, you just have to know them before you sign.
This is general information, not legal advice. Confirm the current rules and your specific situation with the CSLB or a professional before you act.
Common questions
How much can a contractor ask for up front in California?
The down payment on a home improvement contract is capped at $1,000 or 10 percent of the contract price, whichever is less, not counting finance charges. On most sizable jobs that means the legal maximum deposit is $1,000.
Is a 50 percent deposit legal in California?
No. For a home improvement contract, the deposit cannot exceed the lesser of $1,000 or 10 percent of the price. A request for 50 percent down is not allowed, and it is a reason to slow down and verify the contractor.
Can a contractor charge more up front for special-order materials?
There is no special-order exception to the deposit cap. A contractor can schedule progress payments tied to milestones like material delivery, but the initial down payment is still limited to the lesser of $1,000 or 10 percent.
