How Much Deposit Should a Contractor Charge? By Job Size and State

A deposit is not a reward for winning the job. It is the money you need in hand before you can start without financing the customer: the special-order window, the permit, the dumpster, the first week of labor. Size it to those costs and most of the awkwardness disappears, because you can say exactly what the deposit pays for. This guide gives you a way to size it, the state rules that cap it, and the wording that gets it paid the same day the customer approves.

Start from costs, not a percentage

Add up what you commit to before the first invoice would normally go out. For a service call that is a tank of gas and parts off the truck, so the honest deposit is small or zero. For a bathroom remodel it is the vanity, the tile and the plumbing fixtures, most of which are non-returnable once ordered. For a reroof it is the shingles and underlayment, which you may have to pay for on delivery. Write those numbers down; that is your deposit floor.

Then look at the gap between your first cost and your first draw. If the deposit plus the first progress payment keeps you ahead of what you have spent, the schedule works. If not, the deposit is too small or the first draw is too late. The point is simple: at every stage of the job, the customer should have paid you slightly more than the job has cost you so far.

Typical deposits by job size

• Service calls and repairs under about $1,500: no deposit, or a small one if a part has to be ordered. Invoice on completion with a pay link.
• Small projects, $1,500 to $10,000 (fence, water heater, painting, a single-room refresh): 20% to 30%, or the cost of materials if that is higher and your state allows it.
• Mid-size remodels, $10,000 to $50,000: 10% to 30% deposit, then milestone draws tied to things the customer can see (demo done, rough-in passed inspection, cabinets set).
• Large jobs over $50,000: smaller deposit percentage, more draws. A 10% deposit on a $120,000 addition is $12,000, which usually covers the start; the draws carry the rest.

These are market norms, not rules, and where a state caps the deposit the cap wins. A homeowner who has read any consumer guide will expect a deposit under one-third and will push back on 50% whatever the job.

States that cap home-improvement deposits

Most states do not set a statutory limit on a contractor deposit for private work; the contract governs. A handful do, and they are big markets. The table below covers residential home-improvement contracts; commercial work is generally not capped.

• California: the lesser of $1,000 or 10% of the contract price, and payments may never run ahead of the work completed (Business and Professions Code §7159). The CSLB enforces this and consumer guides repeat it, so California homeowners usually know the number.
• Maryland: no more than one-third of the contract price before or at signing (Business Regulation §8-617, enforced by the MHIC).
• Massachusetts: no more than one-third of the contract price, except that special-order materials can be collected up front when they cost more than that (M.G.L. c.142A §2).
• Nevada: residential improvement contracts must include a payment schedule; licensing-board guidance and training materials describe the down payment limit as the lesser of $1,000 or 10% unless the contractor is bonded for it (NRS 624.970). Confirm the current reading with the Nevada State Contractors Board before you quote it.
• Pennsylvania: for home-improvement contracts over $5,000, the deposit may not exceed one-third of the contract price plus the cost of special-order materials (Home Improvement Consumer Protection Act, 73 P.S. §517.7).
• New York: no dollar cap, but every payment received before substantial completion must go into an escrow account within five business days, or be covered by a bond or contract of indemnity (Lien Law §71-a). Spending a New York deposit on another job is the violation, not the size of the deposit.

If you work in a capped state, build the schedule to the cap and make the first milestone draw early and visible: materials delivered to site, permit pulled, demo complete. California contractors commonly write the $1,000 deposit and a materials-on-site draw for the day the special-order items land.

Ask for it on the estimate, collect it on approval

The deposit belongs on the estimate the customer signs, as a line in the payment schedule: deposit amount, what it covers, and when the balance is due. When the customer approves the estimate, the deposit invoice should go out immediately, while the yes is fresh, with a pay link that takes a card or a bank transfer. A deposit requested two days later by email is a deposit that gets paid a week later.

Two sentences do most of the work. On the estimate: “A deposit of $2,400 (20%) is due on approval and covers the vanity, tile and fixtures, which are non-returnable once ordered.” On the deposit invoice: “Thanks for approving estimate EST-1042. This deposit gets your job on the schedule; the balance is invoiced when the work is done.”

Refunds, cancellations and what the deposit buys

Say in writing what happens if the job is cancelled. A fair rule: special-order materials already ordered are not refundable; labor not yet performed is refunded; a cancellation fee covers the time already spent. Several states give homeowners a three-day right to cancel a home-improvement contract signed at their home, so hold off on non-returnable orders until that window closes.

When the balance invoice goes out, show the deposit as a credit line so the customer sees the whole picture: estimate total, less deposit paid, balance due. That one line prevents the most common end-of-job call, “didn’t I already pay you?”

Quick checklist

1. List what you must buy or commit to before day one. That is the floor.
2. Check whether the job is in a capped state (CA, MD, MA, NV, PA) or an escrow state (NY) and build to the rule.
3. Put the deposit and the schedule on the estimate, not on a separate form.
4. Send the deposit invoice the moment the customer approves, with a pay link.
5. Credit the deposit as a line on the balance invoice.
