California Contractor Down Payment Limits: How Much Can You Legally Collect Up Front?
In California, contractors generally cannot collect more than $1,000 or 10% of the contract price before work begins, whichever is less. On a $50,000 remodel, the maximum legal down payment is still just $1,000.
Not whichever is more. Whichever is less.
On a $6,000 painting job, the cap is $600. Once the contract exceeds $10,000, the limit is always $1,000. The 10% figure only applies on smaller jobs.
Where the Rule Comes From
The cap is set by California Business and Professions Code Section 7159.5 and enforced by the Contractors State License Board (CSLB). It applies to home improvement contracts between a licensed contractor and a homeowner or tenant on residential or non-commercial property.
The contract itself must include a section headed “Down Payment,” show the actual amount, and display the following statement in at least 12-point boldface type:
“THE DOWN PAYMENT MAY NOT EXCEED $1,000 OR 10 PERCENT OF THE CONTRACT PRICE, WHICHEVER IS LESS.”
That language isn’t optional. It’s required in the contract.
What Counts as a Home Improvement Contract
Any agreement over $500 in combined labor and materials for work on an existing residential or non-commercial property. Remodeling, repair, installation, replacement, painting, landscaping installation, pool work, solar systems. It’s a wide net.
New construction on a vacant lot is not home improvement. Commercial-only work is not covered. Everything else likely is.
California Contractor Deposit Limits in Practice
| Contract Amount | Legal Maximum Upfront Deposit |
|---|---|
| $5,000 | $500 |
| $10,000 | $1,000 |
| $20,000 | $1,000 |
| $50,000 | $1,000 |
| $100,000 | $1,000 |
Example: $40,000 Kitchen Remodel
- Contract price: $40,000
- Maximum upfront deposit: $1,000
- Remaining balance: $39,000
The remaining $39,000 must be collected through progress payments tied to completed work or materials delivered. It cannot be collected in a lump sum before work is done.
Can a California Contractor Ask for 50% Up Front?
No. On most California home improvement projects, a contractor cannot legally collect 50% up front. The maximum upfront payment is $1,000 or 10% of the contract price, whichever is less, unless a qualifying bond exception applies.
A licensed contractor who collects 25%, 30%, or 50% before work begins on a covered home improvement project may be violating California law. Violations of BPC 7159.5 are grounds for CSLB disciplinary action and are punishable as a misdemeanor.
You Can’t Work Around It With Different Labels
Calling it a “material deposit,” “mobilization fee,” or “setup charge” doesn’t change anything. The cap applies to whatever is collected before work begins, regardless of what it’s called on the invoice or contract.
Contractors who need to order custom materials before breaking ground face real cash flow pressure under this rule. The law doesn’t carve out an exception for it. Structure your progress payments instead.
Progress Payments: How the Rest Gets Paid
After the upfront deposit, subsequent payments must not exceed the value of the work performed or materials delivered at the time each payment is requested. The CSLB is direct about this: it is against the law for a contractor to collect payment for work not yet completed or materials not yet delivered.
If the contract includes a payment schedule, it must:
- Be in writing, with each payment stated in dollars and cents
- Be preceded by the heading “Schedule of Progress Payments”
- Specifically describe what work, materials, or services will be completed for each payment
Vague milestones don’t satisfy the requirement. “Framing complete” paired with a dollar amount works. “Phase 2” alone doesn’t.
The Performance Bond Exception
There is one exception to the deposit limit. A contractor who provides a performance and payment bond, lien and completion bond, or an equivalent approved by the CSLB Registrar is exempt from the cap and can collect the full contract amount up front. The CSLB covers this exception on their website.
Keep Your Payment Schedule in the Contract
Every customer-facing contract needs the required down payment language, a clear progress payment schedule with dollar amounts tied to specific milestones, and no collections above the legal limit before work starts.
Cinderblock lets California contractors build milestone-based payment schedules directly into contracts before they go out, with each phase described and the corresponding payment amount spelled out. When the customer signs, the payment structure is already there.
