What Is a Fair Contractor Deposit? California Rules Explained

While this post references California law, the general principles apply to homeowners in all 50 states. Check your state's contractor licensing board for local rules specific to your area.

One of the most common ways homeowners lose money on a job happens before a single nail goes in. It happens at the deposit. The good news is that California has one of the strongest homeowner protection laws in the country on this. Knowing the law is your first line of defense.

What California Law Says About Contractor Deposits

Under California Business and Professions Code Section 7159, a licensed contractor cannot ask for a deposit bigger than 10% of the total contract price or $1,000, whichever is less. This is for home improvement jobs.

Here is an example. If your job costs $30,000, the most a contractor can legally ask for upfront is $1,000. Not $3,000. A lot of homeowners do not know this. So they pay far more upfront than the law says they have to.

Why This Matters

A big deposit puts the risk on you. A contractor who already has a big chunk of your money has less reason to finish on time. And if that contractor goes out of business, gets hurt, or just walks off the job, getting your money back can be very hard.

The deposit limit is there to protect you. Do not give it up, even if a contractor asks you to.

Exceptions to Know

• Custom materials. If a contractor has to order custom materials that must be paid for upfront, a bigger deposit may be on the table. But it should be written down clearly.
• Material suppliers. Money you pay straight to a supplier for materials works differently than a deposit to the contractor.
• Commercial jobs. The 10% rule is for home improvement, not for commercial building.

Payment Schedule Best Practices

• Tie payments to the work, not to dates on the calendar. Pay as the work hits each stage.
• Never pay ahead of the work that is done.
• Hold back 10% of the total contract until the job is finished and you have signed off on the list of what is left to fix.
• Get every payment in writing before any work starts.

What to Do If a Contractor Asks for More

If a contractor asks for a deposit above 10% or $1,000, you have options.

You can say no and offer the legal limit instead. You can ask them to put any exception in writing. Or you can walk away.

A contractor who pushes back hard on a law that protects you is telling you something about how they work. California law is on your side. Know your rights before you sign anything.
