California contractor deposit exceptions require specific security. Check bond coverage and license records before agreeing to a larger advance.
For a covered California home improvement contract, the ordinary deposit limit is $1,000 or 10% of the contract price, whichever is less. California contractor deposit exceptions require qualifying security covering full performance and payment. An ordinary license bond does not establish an exception under California’s statutory rules.
Special-order materials do not create an exception either, according to Contractors State License Board (CSLB) guidance. Before agreeing to a larger advance, identify the claimed security arrangement and verify that it covers the business signing your contract.
These rules concern home improvement agreements between an owner or tenant and a contractor licensed—or required to be licensed—for the transaction. Home improvement includes residential remodeling, repairs and additions, along with listed improvements such as swimming pools, landscaping and garages. Section 7159 generally imposes its detailed contract requirements when the aggregate price exceeds $500; that threshold is separate from the licensing exemption rules. See Business and Professions Code sections 7151, 7151.2, 7159 and 7159.5.
Calculate 10% of the contract amount, excluding finance charges, then compare it with $1,000. In hypothetical examples, a $6,000 project has a $600 maximum ordinary deposit; a $40,000 project has a $1,000 maximum. The contractor cannot choose the larger number. CSLB’s down-payment guidance explains the calculation.
Verify the contract category separately for these transactions:
These statutory definitions and exceptions make the agreement’s actual scope essential to choosing the payment rule.
Business and Professions Code section 7159.5(a)(8) identifies specific security arrangements covering full performance and payment. Qualifying security exempts the contractor from the ordinary deposit cap, progress-payment schedule requirement and prohibition on collecting ahead of completed work or delivered materials. The statute and Title 16 regulations, sections 858–858.9, distinguish the following arrangements:
| Claimed arrangement | What to establish before relying on it |
|---|---|
| Performance and payment bond, or lien and completion bond for the project | Obtain the actual instrument and confirm that it covers full performance and payment under your contract. |
| Blanket performance and payment bond | Verify CSLB approval for the contracting licensee, the bond’s effective coverage and its current status. |
| Bond equivalent or joint-control arrangement | Obtain the registrar’s approval and documents establishing full performance and payment coverage. The contractor cannot have a financial or other interest in the joint control. |
An ordinary contractor license bond does not establish the security required for this exception. That bond is $25,000 across covered claims involving the contractor’s jobs, rather than $25,000 reserved for each project, as CSLB’s license-bond guide explains.
A blanket bond covers obligations across the licensee’s covered home improvement contracts. Section 858.1 ordinarily requires coverage sufficient for 100% of those obligations, but permits an approved capped alternative for companies meeting specified public-reporting and financial conditions. The blanket-bond regulations therefore do not justify assuming unlimited protection.
CSLB’s consumer contract guidance concentrates on the approved blanket bond and says a contractor with that bond may request the entire contract price upfront. That explains one route through the broader statutory exception. A company’s advertisement that it is “bonded,” or a document labeled “performance bond” or “escrow agreement,” does not by itself establish eligibility.
For a blanket bond, start with the public license detail. CSLB’s Construction Project Checklist says the bond will appear there.
Saving the record and confirming the instrument are practical verification steps; the instrument’s terms still need review. If no blanket bond appears, ask which other statutory arrangement the contractor claims. Its absence does not rule out every exception in section 7159.5(a)(8). Obtain the project bond or approved alternative and ask CSLB to clarify the claimed basis before agreeing to the advance.
Custom cabinets and special-order windows do not create a larger-deposit allowance. A supplier’s demand that the contractor pay early does not itself change the homeowner’s ordinary deposit limit. CSLB expressly rejects a special-order materials exception.
A later materials payment can be a progress payment when it corresponds to materials actually delivered. Absent qualifying security, section 7159.5(a)(5) prohibits requesting or accepting payment beyond the value of work performed or materials delivered, except for the permitted down payment. Calling an advance a “procurement payment” does not establish compliance with that payment restriction.
To verify delivery, request an itemized invoice, a delivery receipt identifying the location and quantities, and photographs or an opportunity to inspect. For completed work, compare the invoice with the contract milestone and observable work. A purchase order or supplier deposit receipt alone does not demonstrate delivery or completed work. If goods remain at a factory or warehouse, clarify what has been completed, who controls the goods and why the payment is claimed to be due.
Track prior payments and credits so the same materials are not billed twice. When subsequent payments become due, use the separate guide to California progress payments and lien releases.
A qualifying exception permits omission of specified down-payment, progress-payment and mechanics-lien warnings; it does not eliminate all contract requirements. Missing warnings do not prove that an exception exists. Section 7159 also requires a notice near the signatures explaining the owner’s right to require a performance and payment bond. That notice is not evidence that a bond was issued. See sections 7159(c)(6) and 7159.5(a)(8).
For an October 30, 2026 agreement, account for contract changes effective January 1, 2026. CSLB’s bulletin dated December 29, 2025 describes contractor email information and email cancellation under AB 1327, and subcontractor disclosures under SB 517. Those changes do not establish a larger-deposit exception. If the scope later changes, reconcile change-order costs with the payment schedule.
Keep the contract, payment request, dated license record and supporting security documents together. If the coverage, contract category or treatment of offsite materials remains disputed, have a California construction attorney review it before agreeing to the advance. Even with a verified exception, you can negotiate a smaller upfront payment.
