The short answer
For an ordinary California home-improvement contract, CSLB states the deposit limit is the lesser of $1,000 or 10% of the contract price. Verify the applicable contract and any documented blanket-bond exception rather than accepting a percentage by habit.

Identify what the payment actually is
Ask whether the request is a deposit under the proposed construction contract, payment for a separately defined completed service, or another charge. Labels do not resolve the issue by themselves. Keep the proposal and payment request together so you can see which work the money is meant to buy. Do not assume renaming a deposit as scheduling money makes its treatment clear.
Check the ordinary rule and exception
Use CSLB’s home-improvement guidance and license record rather than a contractor’s recollection of what everyone charges. The published rule does not create a special-order-material exception. CSLB separately describes an exception for a blanket performance and payment bond on file. A routine contractor license bond is not the same document. If an exception is claimed, verify it directly before deciding. See CSLB consumer guidance for the applicable official information.
CSLB describes the blanket performance and payment bond exception separately from ordinary contractor license bonds.
Separate deposit from later progress payments
The next payment should have its own written trigger. An apparently modest deposit followed immediately by an undefined mobilization charge deserves clarification. Ask what work or delivery supports each amount and where that appears in the contract. This is a payment-structure conversation, not an accusation: both parties benefit when invoices have a clear basis.
Leave a usable record
Ask for a written schedule, a receipt for every payment and the legal name of the recipient. Keep proof of the amount, date and purpose. If the contractor revises the deposit proposal, have the revised contract or schedule reflect it. A verbal concession can be forgotten when someone else in the office sends the first invoice.
How to question the request without derailing the project
Send a short factual note: identify the requested amount, the contract total and the official guidance you are using, then ask for the payment schedule to be clarified. Ask whether the contractor is claiming an exception and where you can verify it. Keep the tone focused on the agreement you are about to sign. You do not need to speculate about the company’s finances or accuse it of planning to abandon the job.
If you have already paid, retain the receipt and avoid creating a new informal arrangement through hurried messages. Ask the contractor to reconcile the payment against the signed schedule and explain the next invoice. When the amount or circumstances are disputed, CSLB consumer resources or qualified legal advice can help identify the appropriate next process. The article’s calculation is not an instruction to reverse a payment or breach an agreement. A useful outcome is a documented starting balance and an understandable schedule for the remaining work, including how future changes and credits will appear.
What to keep beside the first payment receipt
Keep the signed payment schedule, the request that prompted payment and the receipt together. Note whether the amount was applied to the contract balance and check that the next statement agrees. If the office changes the wording of the charge, request clarification rather than assuming the accounting label changes your agreement.
When a contractor says the ordinary limit is impractical, you can acknowledge the concern without accepting an unexplained structure. Ask what compliant arrangement it proposes for your contract and whether an official exception is being claimed. Avoid inventing a workaround yourself, especially one that splits a single job into artificial transactions.
If the discussion remains unresolved, pause the selection decision long enough to obtain reliable guidance. Urgent sales pressure is not evidence that the payment is appropriate. For a project already underway, do not make unilateral deductions based solely on this article; review the documents and seek advice on the specific dispute. The practical outcome you want is simple: both parties can identify the starting payment, its basis, the remaining balance and the work supporting the next invoice. That clarity is more useful than a verbal assurance that everyone in the Bay Area pays this way.
Follow through on the decision
Do not let the first-payment conversation distract from the rest of the contract. Review the complete scope, change process and remaining schedule before committing. A compliant starting deposit does not make an unclear project well defined. Keep each decision visible so you are assessing the whole agreement rather than accepting it because one number was corrected.
Decision checklist
- Identify the contract type and the actual purpose of the request.
- Apply the ordinary lesser-of calculation where that rule is applicable.
- Verify a claimed blanket-bond exception directly rather than accepting a slogan.
- Keep the receipt, schedule and remaining balance in one record.
Applying the ordinary calculation
Hypothetical example. In a $6,000 home-improvement contract, 10% is $600, so the ordinary maximum described by CSLB is $600. In a hypothetical $40,000 contract, 10% is $4,000, so the ordinary maximum is $1,000. These examples illustrate the lesser-of calculation; they do not determine whether your agreement qualifies for a specific exception or whether a later invoice is properly supported.
Related questions
Are custom cabinets an automatic exception?
No. CSLB explicitly says special-order materials do not create an exception to the ordinary deposit limit.
What if the contractor says it has a bond?
Ask which bond and verify the claimed exception through CSLB. Ordinary licensing-bond evidence is not enough.
