One-third of the contract price is the usual ceiling, and in a handful of states it is the law rather than the custom. In California and Nevada it is much lower: $1,000 or 10 percent of the contract, whichever is less (B&P 7159.5; NRS 624.970). On a $60,000 kitchen that is one thousand dollars, before you order a single cabinet. Take $6,000 instead and you have committed a misdemeanor carrying a fine of $100 to $5,000 and up to a year in county jail, on top of whatever your licence board decides. Both statutes also contain the way out, and it is not a loophole. Post a bond, or bill your first draw on delivered material rather than on a date.
What is the legal cap on a contractor's deposit?
There is no national number. Five states worth knowing, because they cover the biggest residential markets and because their rules are shaped differently from each other:
| State | Money you may take before work starts | Statute |
|---|---|---|
| California | $1,000 or 10% of the contract, whichever is less | B&P 7159.5(a)(3) |
| Nevada | $1,000 or 10% of the aggregate contract price, whichever is less | NRS 624.970(2)(g) |
| Maryland | One-third of the contract price, and nothing at all before the contract is signed | MHIC |
| Massachusetts | The greater of one-third or the actual cost of special-order or custom materials | MGL c.142A s.2 |
| New York | No cap - but every pre-completion payment goes into escrow within five business days | Lien Law 71-a(4) |
Nevada's version is newer than most contractors realise. It applies to contracts signed on or after October 1, 2023, and it covers ordinary residential improvement work on an owner-occupied single-family home. Pools and solar sit in their own sections of the same chapter with their own numbers.
This is not the whole map. Other states cap deposits too, and the caps move when legislatures sit. Read your own board's contract requirements before you print anything, because the number in your contract template is a licence question, not a preference.
What happens if you take too much?
In California, three things, and the fine is the smallest of them. Section 7159.5 makes an excessive downpayment a misdemeanor punishable by $100 to $5,000, or up to a year in county jail, or both. The CSLB treats it as grounds for discipline against the licence separately. And during a declared natural disaster the court is required to impose the maximum fine, which is aimed squarely at whoever shows up in a burn zone with a clipboard.
The third consequence is the one that actually costs money. In Nevada, a payment schedule that does not comply with NRS 624.970 is voidable by the homeowner. So the schedule you were counting on to fund the job becomes the first thing his attorney strikes out, and you are left arguing about the value of work performed on a job you have already half built. Maryland adds its own trap: taking any money before the contract is signed is a violation by itself, whatever the amount. The handshake cheque at the kitchen table is the violation.
How do you buy materials when the deposit is capped at $1,000?
You bill the delivery. This is the clause most contractors in cap states have never read, and it is sitting in the same section as the cap: except for a downpayment, the contractor "shall neither request nor accept payment that exceeds the value of the work performed or material delivered."
Material delivered. Not material installed.
So the first draw is not a date, and it should never be written as one. "First draw: 30% at start of work" is a request for money against nothing, and a homeowner who has read his own contract can refuse it. Write it this way instead:
$8,400 due upon delivery of the cabinet package (Supplier quote #4471) to the job site.
Then photograph the pallet next to the delivery ticket on the day it lands, and staple both to the invoice. The payment request stops being a request. It is documentation of value already sitting on the client's property, which is exactly the test the statute sets. Nevada's rule is shaped the same way - payments may not exceed 100 percent of the value of the work performed at any point.
Massachusetts wrote the answer straight into the statute and skipped the workaround entirely. The deposit may be the greater of one-third or the actual cost of materials "of a special order or custom made nature, which must be ordered in advance of the commencement of work." Ten-week lead time on windows, a custom stair rail, a cabinet order that a supplier will not release without payment. Massachusetts lets you collect what they really cost. California does not, and the CSLB says so plainly: there is no special-order exception to the $1,000 rule.
Can you get out of the cap legally?
Yes. Both statutes put the door in writing.
California exempts a contractor furnishing a performance and payment bond covering full performance and payment, approved by the registrar. That exemption lifts the downpayment cap along with the progress-payment restrictions. Nevada's is more specific and easier to price: the cap "does not apply if the residential contractor has filed with the Board a bond solely for the protection of consumers in the amount of $100,000."
New York is not a cap at all, which trips up contractors crossing the line from Connecticut. You may take a real deposit. You may not spend it. Every payment received before substantial completion goes into an escrow account within five business days, and the money stays the owner's property held in trust until it is applied to his job. The alternative is posting a bond or an irrevocable letter of credit with the owner, delivered within ten business days of taking the money.
Here is the position. For a one-truck outfit doing $30,000 jobs, the bond costs more than the problem it solves, and the draw-on-delivery schedule solves the same problem for the price of a photograph. Price the bond when your jobs routinely carry five figures of special-order material that a supplier will not release on your account.
What should you take where no statute applies?
One-third, and only when one-third is roughly what the material package and mobilisation actually cost you. Size the deposit to the job's opening expenses, not to your bank balance.
This is worth being blunt about. If you need 50 percent down to make payroll, the deposit is not funding this job - it is covering the last one, and every new client is paying for the previous client's work. That gap does not close on its own. It closes when the price is right, which is a question about what an hour of your time actually costs rather than a question about deposits.
Two habits that cost nothing. State the deposit as a dollar figure rather than a percentage, because a percentage invites a counter-offer and "$2,850 for the window order" does not. And put it on a document that binds, with the scope it attaches to - which is the difference between an estimate and a quote, and part of what belongs on the estimate in the first place.
What this misses
Five states is not fifty. Other states cap deposits, some by statute and some by regulation, and several have changed in the last three years. Treat the table above as a warning that the question exists in your state, then go read your own board.
These are home improvement statutes. They generally cover residential work on existing owner-occupied property. New construction, rental property and commercial jobs usually sit outside them, and Nevada's residential improvement section explicitly excludes pools and photovoltaic work, which have their own rules in the same chapter.
This is not legal advice, and the text moves. Nevada's rule is barely three years old. Read the current section rather than an article about it before you change a contract.
A deposit cannot rescue a bad number. Collecting one-third of the wrong price only means you are one-third funded on a job that was never going to pay. BidWalk prices the material package line by line while you are still standing in the house, so the draw you write on delivery is a number you can defend when the homeowner asks what it covers.
