CALIFORNIA CONTRACT CHECKLIST
California Home Improvement Contract Checklist for Contractors
Use this checklist before a California home improvement contract goes out for signature. It organizes the project facts, payment terms, notices, change-order setup and final review points a contractor should verify against the current law and the specific job.
Last reviewed: September 26, 2026
Before you use the checklist
Once a typical California home improvement project goes above the $500 threshold, the agreement belongs in writing, and that figure counts labor, services and materials together. A few kinds of jobs run under different rules, so start by making sure the ordinary §7159 home-improvement-contract framework actually fits the transaction.
Think of the list as a second set of eyes rather than a legal opinion. For the controlling requirements, go to the current statute and CSLB guidance.
15-point California home improvement contract checklist
Contractor and salesperson information
Licensed business name, business address and license number. If a registered home-improvement salesperson made the sale, add their information as well.
Customer and project information
Who's hiring you, where the work happens and what project this agreement covers. Owner, property and contact details should read the same on every page.
Contract price
The agreed price in dollars and cents. Any finance charges stay separate from the contract amount, as the statute requires.
Scope of work
Enough detail that the customer can see what you're agreeing to do and what you aren't. Spell out installation, repair, demolition, cleanup and anything else specific to this job.
Review California contract requirements →Significant materials and equipment
The materials and equipment that define the job. Where it matters, product type, quantity, model or finish heads off arguments later.
Start and completion dates
Expected start and substantial-completion dates that your crew can realistically hit.
Down payment
Collecting a deposit? Test it against the general California cap: compare $1,000 with 10% of the contract price and use the smaller figure, unless a valid statutory exception applies.
Review the down-payment guide →Progress-payment schedule
Later payments broken into defined stages, each tied to the work, services, materials or equipment that stage represents. No arbitrary installments.
Review the progress-payment guide →Required notices and disclosures
The notices and disclosures that apply to this transaction. Under §7159 that can include insurance status, CSLB information, change-order information and cancellation paperwork.
Mechanics lien warning
The required mechanics-lien warning is in the package, and you know how payments and lien releases will be handled on this job.
Review the mechanics-lien guide →Cancellation notice
Cancellation paperwork that fits this transaction. Deadlines vary with the customer's circumstances, where the contract was negotiated and other statutory rules.
Review the cancellation-rights guide →Change-order terms
A change-order process agreed before anything changes. Later changes get written down and signed before the changed work begins, with price and schedule effects shown.
Review the change-order guide →Signatures and customer copy
Signed and dated by the required parties before covered work starts, with the completed signed copy in the customer's hands.
Project record and audit trail
The signed contract, change orders and related records kept together, so you can show what was agreed and when. That's good recordkeeping practice; it isn't a summary of every legal retention rule.
Final pre-signature review
Read it the way your customer will. Names, amounts, dates, scope, attachments, payment stages, notices and signature lines should all agree with each other. Then confirm what the actual job requires.
Quick final review before sending
- Names and license details match the contractor record
- Scope, price and dates tell one consistent story
- Down payment and progress payments match the planned work
- Required notices and cancellation paperwork are included
- Change-order process is clear before field work changes
- Customer copy and signature workflow are ready
Unsure about any of these? Pause and sort it out before anyone signs. A checked box shouldn't stand in for an answer you don't have yet.

Building this checklist manually for every project?
Running fifteen checks by hand on every job gets old fast. ContractBuilderAI builds many of them into a guided California contract workflow, with project intake, draft assistance for scope and materials, payment-stage setup, review checkpoints, e-signature and an audit trail.
ContractBuilderAI helps organize the process. The contractor remains responsible for the final agreement and for confirming which requirements apply to the project.
