What to do about a contractor dispute in Contra Costa County

Updated August 2026 · California contractor and small claims rules

Can I resolve a contractor dispute without going to court?

If the work is unfinished, defective, or far more expensive than you were led to expect, start by getting your facts in one place. If you are the contractor and have not been paid, do the same. Most disputes calm down when both sides can see the contract, messages, photos, invoices, change orders, and a simple timeline.

If you do end up filing, Contra Costa County small claims cases are heard in Martinez, Pittsburg, and Richmond. That matters because a realistic settlement plan should take into account the inconvenience of preparing papers, arranging service, and showing up at one of those court locations.

What should I do first if a contractor job went bad?

California generally requires a demand before you file a small claims case under Code of Civil Procedure § 116.320. That does not mean your letter has to sound like a lawyer wrote it. It means you should clearly say: what work was agreed to, what actually happened, what amount you believe is owed or should be refunded, and what you want next.

• Attach the contract or estimate, if you have one.
• Attach photos or videos of unfinished or defective work.
• List payments made and when they were made.
• Include texts or emails about changes, delays, or promises to return.
• Ask for one concrete outcome: finish the work correctly, refund part of the price, or pay the unpaid balance.

Keep your tone calm. A letter that sounds reasonable is more likely to work in negotiation and more useful later if the dispute keeps going.

What if there was no written contract?

If your agreement was written, the time limit to sue is generally 4 years. If it was oral, the time limit is generally 2 years. There can be exceptions, so do not wait if the dispute has been dragging on.

For home repair and improvement disputes, people often focus only on the final bill. That is not enough. You also want proof of the original scope, any changes, and whether the contractor was given a fair chance to fix the problem.

Do I need to check whether the contractor was licensed?

Licensing does not automatically decide every dispute, but it can change how the other side evaluates risk. If you are the homeowner, find out whether the person or business you hired was properly licensed for the type of work. If you are the contractor, make sure your license status and business name match the paperwork you used on the job.

This is especially important in disputes about deposits, incomplete work, change orders, and extra charges that were never clearly approved. Even when people are angry, many cases settle once both sides understand what can and cannot be proven.

Should I try mediation for a contractor dispute?

Mediation is a structured settlement conversation with a neutral person. The mediator does not decide who wins. The point is to help both sides reach an agreement they can live with, which can matter a lot in contractor disputes where each side tells a very different story.

A good mediation can cover more than money. You can discuss cleanup, return of materials, warranty questions, access to the property, inspection timing, and a final release so the dispute does not restart later.

If you want a low-cost way to organize a demand and invite settlement, Judicaid is one option. It is not legal advice, but some people use it to present the dispute clearly before deciding whether to go further.

How do I decide between negotiation, mediation, and small claims?

For individuals, the usual small claims limit is $12,500. If your dispute is within that range, small claims may be realistic. But before you get there, ask yourself whether a narrower settlement ask would solve the real problem.

What matters most in a Contra Costa County small claims case?

Contra Costa County hears small claims matters in Martinez, Pittsburg, and Richmond. For many people in Concord, Walnut Creek, Martinez, and San Ramon, the Martinez courthouse at 725 Court Street, Martinez, CA 94553 may be the most relevant location. For people in Antioch, Pittsburg, and Brentwood, the Pittsburg courthouse at 1000 Center Drive, Pittsburg, CA 94565 may be more practical.

Those local details matter before you file because showing up takes time off work, planning around childcare, and getting your evidence ready in a format you can actually use at the hearing. If you need to confirm filing logistics or basic court information, the court's main phone is (925) 608-1000, and the filing clerk window hours are 8:00 a.m. to 4:00 p.m., with most clerks answering phones from 8:00 a.m. to 3:00 p.m..

What to bring if settlement fails

• A short timeline from the first estimate to the last contact
• The contract, estimate, and all change orders
• Proof of payments, including screenshots if needed
• Photos showing the condition before, during, and after the job
• Written repair estimates or completion estimates from someone else, if you have them
• Copies of your demand letter and any responses

What if I am the contractor and the customer will not pay?

Unpaid contractor disputes often turn on scope changes, delays caused by the owner, access problems, and verbal approvals that were never written down. If you are the contractor, be ready to show the original price, what changed, who approved the changes, and why the final bill increased.

If you can still talk productively, settlement may save both sides money. A partial payment now, a written punch list, or a neutral inspection process can sometimes salvage a dispute that would otherwise end in court.

What should a settlement agreement include?

1. Name the people or businesses involved.
2. Describe the property and the job clearly.
3. State the payment, refund, repair, or completion terms in plain language.
4. Say who supplies materials, permits, access, or cleanup if that still matters.
5. Include a final release if the deal is meant to end the dispute completely.
6. Make sure both sides sign and keep copies.

If you use mediation or a service like Judicaid, the written outcome matters more than the conversation that got you there. The agreement should be specific enough that a stranger could read it and understand exactly what each side promised.

When is it smarter to stop pursuing the dispute?

That does not mean the other side was right. It means your time, stress, and the cost of chasing the matter may outweigh a likely recovery. People in Contra Costa County often reach this point after realizing they would need to miss work, travel to one of the small claims locations in Martinez, Pittsburg, and Richmond, and spend more energy than the case is worth.

If you are unsure, write out your best-case and worst-case outcomes before taking the next step. That simple exercise often makes the decision clearer.
