Charging for design, and taking a deposit

These two things look unrelated and they are the same problem: this trade asks you to spend real money — hours on a design, pallets of stone — before anybody has paid you. Everything below is about closing that gap legally.

The deposit cap, which almost nobody checks

Every trade article you will read, including two of ours before this one, says take a deposit that covers your materials. In several states that advice is illegal.

So if you cannot take a big deposit, how do you avoid funding somebody else’s patio? Three answers, and all of them are better than a large deposit anyway.

Structure the payments instead

• Tie stage payments to milestones, not dates. “On completion of the excavation and base” is a fact anyone can verify; “halfway” is an argument. Milestones can legitimately front‑load your material spend because the work has been done.
• Sequence the job so materials arrive when they are needed, not on day one. A pallet in the driveway for two weeks is your money sitting in the rain.
• Open a supplier account with terms. Thirty days from your merchant is the cheapest working capital in this trade and it costs nothing but paperwork.
• Take the design fee first — a separate contract for a separate service, which is not a construction deposit at all.
• Bill promptly at every stage. Most landscaping cash problems are invoicing problems wearing a costume.

The protection that exists because you cannot take a big deposit

This is the part nobody tells new landscapers, and it is worth more than any deposit.

Mechanics lien rights let an unpaid contractor place a claim against the property itself. They are strong — and in roughly 35 states they depend on serving a preliminary notice within a deadline of typically 10 to 90 days of first supplying labour or materials. In California that window is 20 days from starting work.

Miss it and you do not weaken your claim. You permanently lose lien, stop notice and payment bond rights, however right you are about the money.

• Find out whether your state requires a preliminary notice, and its deadline. Once. Write it on your job checklist.
• Serve it as routine on every project above a threshold you set — not only the ones you are worried about. It is not an accusation and experienced homeowners are used to receiving them.
• Explain it at the quote so it does not land as a shock: it is a standard construction notice that protects both sides.
• Diary the deadline from first day on site, not from the contract date.
• Know your lien filing deadline too — the notice preserves the right; the lien itself has its own clock.

Charge for the design

A free design is not marketing. It is unpaid work you hand to a customer who can walk it down the road to somebody cheaper — and in this trade that happens constantly, because the design is the hard part and the digging is not.

• Deliver something real: a plan, a plant list, and a phased budget. That is what makes the fee obviously worth paying.
• Phase the plan deliberately. Most people cannot fund a whole garden at once, and a three‑year plan is three jobs rather than one lost one.
• Be clear who owns the drawing if they do not proceed. Say it in the design agreement, before it matters.
• Do not design for free to “win the build”. The customers who demand it are the ones who will haggle the build.

What the quote itself must say

• Sections, priced separately — softscape and hardscape, so a customer can scale to budget without you starting again.
• The deposit, the stages and what triggers each one.
• What completion means, so the final payment does not float on a feeling.
• Change orders in writing, priced and agreed before the work. “While you’re here” is how a 20% margin becomes 4%.
• Exclusions — unknown obstructions, drainage, removal of the old patio, tree work, anything below ground nobody has seen.
• A validity period. Thirty days; material prices move.
