Updated December 2025 – San Diego County

In San Diego outdoor living projects, the biggest payment mistakes usually fall into two categories:

• Paying too much too early without milestone proof.
• Paying without paperwork (like lien releases) that protects you if subs or suppliers aren’t paid.

This guide explains California’s core payment rules for home improvement contracts and shows you how to structure deposits and progress payments safely using milestone-based schedules, documentation, and lien-release best practices.

TL;DR — The Safe Payment Rules

California Home Improvement Contract Payment Rules (What the Law Requires)

For most residential outdoor living projects, California’s home improvement contract rules set clear guardrails around deposits and progress payments. Here are the homeowner-level takeaways:

• Down payment cap: The down payment may not exceed $1,000 or 10% of the contract price, whichever is less.
• No paying ahead (except the deposit): Progress payments must not exceed the value of work performed or materials delivered.
• Written payment schedule: If there are progress payments, the contract should include a schedule in dollars and cents tied to work/materials in each phase.
• Lien release leverage: After you make a payment, you can request releases and you may withhold further payments until releases are furnished.

1) Deposits — What’s Normal vs Risky (and CA Limits)

A deposit is meant to reserve scheduling capacity and initiate early planning/procurement — not to bankroll another job.

If you’re asked for more than the cap as a “deposit,” slow down and ask the contractor to explain how they’re structuring compliance. A clean approach is to keep the deposit within the cap and then use progress payments tied to real milestones.

2) Progress Payments — Milestones + Proof (CA Compliance)

The safest payment schedules are milestone-based. California also expects that payments don’t get ahead of work performed/material delivered.

A clean schedule should read like a checklist. Here’s an example format that aligns with strong project management and good homeowner protection:

If a contractor can’t describe their milestones and what “done” looks like at each one, it’s a sign they’re operating without a disciplined system.

3) Lien Releases — Pair Paperwork With Payments

Even if you pay your contractor, subcontractors and suppliers may have lien rights if they aren’t paid. The practical protection is pairing payments with lien releases.

4) The 3-Day Right to Cancel (California)

Many home improvement contracts are signed at the homeowner’s property (not at the contractor’s office). In those situations, California consumer rules commonly provide a three-business-day right to cancel, and the contractor must provide the required cancellation notice.

• Make sure you receive cancellation information in writing with your contract.
• Know the exceptions: some emergency “service and repair” situations can be treated differently.
• Seniors: California also provides enhanced cancellation protections for seniors in certain transactions.

5) Allowances & Exclusions: The Hidden Payment Trap

A payment schedule can look “reasonable” even when the bid isn’t. The fastest way hidden costs show up is through low allowances and vague exclusions.

• Low allowances: appliances, lighting, tile/stone, and planting allowances that don’t match what you actually want.
• Exclusions: electrical, permits, engineering, drainage upgrades, demo/export “as needed.”
• By-others language: costs pushed onto you outside the bid total.

If you want to spot these traps quickly, read our Hidden Costs (Allowances & Exclusions) guide.

6) Red Flags That Signal Payment Risk

• Deposit request above CA cap (or pressure to “get around it”).
• Front-loaded payments not tied to clear milestones and proof.
• Verbal change orders or “we already did it” invoices.
• Refusal to provide lien releases or dismissing them as unnecessary.
• Cash discounts that feel designed to avoid traceability and documentation.
• Constant requests for more money to keep crews on the job.

Payment Safety Checklist (Print-Friendly)

• Deposit complies with CA cap ($1,000 or 10%, whichever is less).
• Contract includes cancellation notice and required disclosures for at-home signings.
• Payment schedule is milestone-based in dollars and cents.
• Progress payments never get ahead of work performed/materials delivered.
• Subsurface work is photo documented before it’s covered.
• Conditional lien releases are collected before each payment.
• Unconditional releases are collected after payments clear.
• All change orders are written and approved before work starts.
• Allowances and exclusions have been clarified in writing.

If you’d like, we can review your deposit and payment schedule and flag where risk is hiding — especially in allowances, exclusions, and change-order language.

FAQs — Deposits & Payment Schedules (California)

What is the maximum down payment (deposit) in California for a home improvement contract?

For most home improvement contracts, the down payment may not exceed $1,000 or 10% of the contract price, whichever is less.

Can a contractor charge more than the cap because materials are special-order?

The down payment cap is still the rule. A clean approach is to keep the deposit within the cap and structure progress payments tied to real milestones and delivered materials.

Do I really have a 3-day right to cancel?

Many home improvement contracts signed outside the contractor’s place of business include a three-business-day right to cancel and require cancellation notice documentation. Exceptions can apply in emergency “service and repair” situations and other specific circumstances.

What is the safest way to structure payments?

Milestone-based payments tied to verifiable deliverables, paired with lien releases and documentation. Avoid vague “percent complete” billing without proof.

Can INSTALL-IT-DIRECT review my payment schedule?

Yes. We can review your bid and payment terms to highlight risk areas and show what a structured milestone-based approach typically looks like. For legal advice, consult a California construction attorney.
