For most California home improvement contracts, the down payment cannot exceed 10% of the contract price or $1,000, whichever is less. Later payments should reflect completed work or materials actually delivered, rather than calendar dates or promises. A rare bond exception exists, so verify any claimed exception with the Contractors State License Board (CSLB).
Whether you are planning a remodel, ADU, or addition in San Jose, a clear payment schedule makes the project easier to follow. You should understand what each invoice covers, how it matches your contract, and what remains unpaid. These same statewide protections matter throughout Santa Clara County and the South Bay.
The California contractor down payment limit
On a $200,000 home improvement contract, the usual maximum down payment is $1,000, not $20,000. On an $8,000 contract, it is $800. The rule uses the smaller amount, not whichever figure the contractor prefers.
CSLB’s consumer alert specifically includes ADU construction among covered home improvement projects. A large project does not automatically justify a large deposit, and ordering custom cabinets does not by itself create an exception. Be careful when an upfront charge is relabeled “mobilization” without explaining what has actually been earned or delivered.
There is a limited exception for contractors with a qualifying blanket performance and payment bond on file with CSLB. This is different from the ordinary contractor license bond. If someone relies on it, verify the specific bond and its effect on your contract directly with CSLB before paying.
Plans and permitting also deserve clear treatment. Ask what services have been completed and how the charge fits the signed agreement. Do not assume a separately labeled design or permit fee automatically avoids the home improvement payment rules.
What sensible payment milestones look like
Home remodel payment milestones should describe something you can verify. “Framing completed as described in the contract” is clearer than “payment due four weeks after signing.” A calendar helps coordinate billing, but the passage of time does not establish that a milestone has been earned.
For each invoice, compare the milestone description, work performed, materials delivered, previous payments, and remaining balance. If a phase is only partly complete, ask for an explanation before treating it as fully earned. An inspection can help document progress, but it does not replace the contract’s definition of that milestone.
Allowances and change orders belong in writing
An allowance is a budget provision for an item not fully selected or priced when the agreement is signed. Ask exactly what it covers. For example, does a tile allowance include only the tile, or also tax, delivery, installation, and setting materials? A vague allowance can make an apparently affordable proposal difficult to compare.
Keep a selection record showing the allowance, the actual selection, and any credit or additional cost. Confirm the contract’s treatment of markups and installation differences before approving an upgrade. Do not assume an allowance is a fixed quote for every possible product.
CSLB says changes to contract price or scope require a written change order signed by the homeowner and contractor before the change. It should explain the revised work, price adjustment, and any schedule impact. Agree how the change affects payment milestones, too. A conversation on site is useful for exploring options; follow it with the signed document before authorizing changed work.
Contractor payment red flags
A request needs clarification when it does not match the agreement. These patterns deserve particular attention:
• Large upfront payments. Ask how the amount complies with the deposit rule. A busy schedule or material reservation is not, by itself, proof of an exception.
• Billing for unfinished work. Ask which work or delivered materials support the charge. “We will finish next week” is different from a completed milestone.
• Repeated invoice errors. Duplicate charges, missing credits, unexplained changes, and incorrect balances should be corrected in writing. One mistake may be clerical; a recurring pattern makes reliable tracking harder.
• Pressure to pay in cash. Cash alone does not prove wrongdoing, but urgency, an undocumented discount, or resistance to a receipt should concern you. Prefer a traceable method and a receipt identifying the business, project, invoice, and amount.
Verify unexpected changes to payment instructions through a phone number you already trust. Avoid sending money to a new account simply because an email appears to come from your contractor.
Check the contractor’s CSLB license
Start at CSLB’s official license-check service. Search the license number and compare the business name with your proposal, contract, and invoices. Check current status and classifications, then review the available bond, workers’ compensation, and disciplinary information. A license number printed on a truck is a starting point, not verification.
Ask the contractor to explain any mismatch before signing or paying. Save a dated copy of your check and recheck when circumstances change. Licensing records are useful, but they do not replace checking references, understanding the scope, and reviewing your San Jose remodel contract carefully.
Keep lien paperwork with payment records
Paying the general contractor does not necessarily prove that subcontractors and suppliers have been paid. CSLB recommends obtaining appropriate conditional releases before payment and unconditional releases from the claimants paid afterward. Use CSLB’s prescribed forms and match the claimant, period, and amount to the payment.
A preliminary notice is not itself a mechanics lien. Do not ignore notices or assume a receipt settles every potential claim. If lien paperwork is unfamiliar, get help reviewing it before the next payment.
What to do if a payment dispute comes up
Begin with a written, specific question: identify the invoice, disputed line, contract milestone, and supporting photos or records. Ask for a corrected invoice or an explanation with documentation. Keep the contract, change orders, payment history, messages, and inspection records together.
Confirm any resolution in writing, including the corrected balance and next milestone. Avoid treating a disagreement as a reason to stop every payment automatically. Before withholding money, terminating the contract, or responding to a lien threat, get advice about your agreement and the applicable deadlines from a California construction attorney.
CSLB accepts complaints involving contractor-law violations and may provide dispute-resolution assistance. Its investigation does not guarantee a refund. Court or other remedies may be needed to recover money; the appropriate route depends on the facts. A city inspection or permit approval addresses a different issue from whether an invoice is contractually due.
Frequently asked questions
Can a contractor ask for 50% upfront?
For a typical covered home improvement contract, that exceeds the usual down-payment limit. Verify any claimed blanket-bond exception directly with CSLB rather than relying on a verbal explanation.
Can I pay for materials before installation?
Delivered materials can support a progress payment even before installation. An order confirmation or promise of future delivery is not the same thing. Check the contract and the value actually delivered.
Should I pay every Friday?
Weekly invoicing can be convenient, but the invoice still needs to match earned progress or delivered materials. A billing date alone does not justify advance payment.
Does a CSLB complaint get my money back?
Not necessarily. CSLB regulates contractors, and its complaint process does not guarantee restitution. Review your options and deadlines with qualified counsel when money or lien rights are at stake.
Planning your next project
If you are considering a remodel, ADU, or addition in San Jose or the South Bay, EDR Design Build offers a consultation to discuss your scope and planning questions. Ask how the proposed milestones would connect payments to your particular project before construction begins.
