What is a California contractor dispute demand letter?
A contractor dispute demand letter is a written notice telling a contractor that they have failed to perform under your agreement and demanding a specific fix — completion, correction of defective work, or a refund. It works best when you have a written contract or estimate, proof of payment, and photos of the work, because those make the breach clear and show you are ready to escalate to the licensing board or court.
When to send one in California
- A contractor took your deposit and never started or abandoned the project mid-way.
- The completed work is defective, not to code, or not what your contract specified.
- A contractor is demanding more money than the agreed contract price without justification.
- Work is dragging far past the agreed completion date with no valid reason.
- A contractor used the wrong materials or cut agreed scope without your approval.
How to write a California contractor dispute demand letter
- 1
Review your contract and scope
Reread the written contract or estimate, the agreed price, the payment schedule, the completion date, and the exact scope of work.
- 2
Document the current state of the work
Take dated photos and video of what was and was not done, and note any defects or code issues. Get a second contractor’s written assessment if you can.
- 3
Total what you have paid and what is owed
Add up all deposits and progress payments, and compare them to the value of work actually completed.
- 4
Decide on the remedy you want
Choose clearly: completion by a deadline, correction of defects, a partial refund, or a full refund of an unearned deposit.
- 5
State the breach plainly
Reference the contract provisions the contractor failed to meet — abandonment, defects, missed deadlines, or unauthorized charges.
- 6
Make a specific demand and deadline
Demand the exact remedy and dollar figure with a firm deadline, commonly 14 days.

Evidence to gather for a California contractor dispute dispute
Good to know in California
California requires deposits back within 21 days with an itemized statement, and for deductions over $125 the landlord must attach receipts or invoices. As of 2024 most landlords may collect no more than one month’s rent as a deposit, a major tenant-friendly change. Small claims allows individuals up to $12,500 (entities are capped at $6,250) and lawyers cannot appear for you at the initial hearing, so a precise demand letter referencing Civil Code § 1950.5 sets up your case well.
