How much deposit can a contractor legally ask for?
Short answer
Some places cap home improvement deposits by law. California limits the down payment to 10% of the contract price or $1,000, whichever is less, and Massachusetts and Maryland generally limit it to one-third. Many other states and most Canadian provinces set no fixed percentage, so the contract controls. Whatever the rule, a deposit far ahead of the work actually being done is a risk worth questioning.
A deposit helps a contractor book your job and order materials. The question is how much is reasonable, and in some places the law answers it for you.
This guide is educational, not legal advice. Rules change and have exceptions (for example, special-order materials or licensed contractors with bonds). Check with your state or provincial consumer protection or licensing office.
1. Examples of legal deposit caps
| Place | Rule for home improvement deposits | Notes |
|---|---|---|
| California | 10% of the contract price or $1,000, whichever is less. | Set by Business and Professions Code 7159.5; enforced by the CSLB. |
| Massachusetts | No more than one-third of the total price, unless special-order materials cost more. | Home Improvement Contractor law (M.G.L. c.142A). |
| Maryland | No more than one-third of the contract price. | Maryland Home Improvement Commission rules. |
| Most other states | No fixed cap; the written contract controls. | Some cities or counties add their own rules. |
| Canada | Generally no fixed percentage cap. | Provincial consumer protection laws focus on written contracts and cancellation rights. |
2. Red flags
Above your local cap
If a legal cap applies and the request is higher, ask the contractor to explain or adjust it.
Full payment before work
Paying everything up front leaves you little leverage if the job stalls.
Cash only
Cash is hard to trace or dispute. A cheque or card leaves a record.
No written contract
The FTC recommends a written contract with a payment schedule before you pay anything.
3. What to say
Asking for a smaller deposit
- 1.“Thanks for the quote. I'd like to go ahead, but the deposit is [amount].”
- 2.“Could we tie payments to milestones instead, with a smaller deposit to start?”
- 3.“I'm happy to pay for special-order materials directly when they're ordered.”
The one thing to remember
Pay as the work happens
The safest payment schedule keeps what you have paid close to the value of work actually done.

Common questions
Is a 50% deposit normal?
It is common for some custom work, but it is above legal caps in places like California and Massachusetts. Ask why and consider milestone payments.
Does Canada cap contractor deposits?
Most provinces do not set a fixed percentage. Check your provincial consumer protection office and your contract.
What if I already paid too much?
Keep records, contact your licensing board or consumer protection office, and ask about a payment plan tied to progress.
