What to do about a contractor dispute in San Bernardino County
Updated August 2026 · California contractor and small claims basics
What should I do first if a contractor job went bad?
Start by collecting proof and making a clear written demand. In most cases, you should ask for a specific fix, refund, or payment before you file a small claims case, and California generally requires that demand step first under Code of Civil Procedure § 116.320.
If you are a homeowner, tenant, or property owner, gather the contract, change orders, text messages, emails, photos, invoices, receipts, and any timeline you were given. If you are the contractor, gather the same things from your side, including proof of work completed, materials bought, and messages about approval of extra work.
Then send one calm, organized demand letter. Say what happened, what you want, and what documents support your position. Keep the tone practical. A strong demand letter can resolve a lot of cases because it shows you are prepared.
- Describe the job and the original agreement in plain language.
- List what went wrong: unfinished work, poor workmanship, delays, surprise charges, or nonpayment.
- State what you want: completion, repair, partial refund, full refund, or payment of the unpaid balance.
- Attach or mention photos, invoices, estimates, and messages.
- Keep a copy and proof that you sent it.
Do I have to send a demand letter before small claims?
Usually, yes. California small claims procedure generally requires you to ask for payment or another resolution before filing, under Code of Civil Procedure § 116.320.
That does not mean you need a formal legal letter. It means you should clearly ask for what you are owed or what needs to be fixed before turning to the court. If you skip that step, it can weaken your position or slow things down.
What if I live far from the courthouse in San Bernardino County?
This matters more here than in many counties. San Bernardino is the largest county in the contiguous United States by area, so the difference between the right and wrong district courthouse can be a two-hour drive, so filing in the right district is not just technical — it can save you major time, stress, and travel.
The San Bernardino County Superior Court handles civil cases in this county, but where you go can affect how manageable the process feels. If you are in places like Victorville, Ontario, Rancho Cucamonga, Fontana, Chino, Rialto, Redlands, or San Bernardino, check the right court location before you make plans, especially if you may need to appear in person.
If you need civil filing information for the San Bernardino district, the court lists 247 West Third Street, San Bernardino, CA 92415. For general civil division information, the line listed by the court is (909) 708-8678.
Can I use mediation instead of suing?
Yes, and for contractor disputes it is often one of the best first options. Mediation can work well when both sides agree there is a real problem but disagree about money, timing, quality, or what was promised.
Mediation is a structured negotiation with a neutral third person who helps both sides try to reach an agreement. It is not a judge, and no one forces an outcome. This can be especially useful when the job is partly done and both sides still want a practical solution, like a punch-list, staged payment, or refund tied to repairs.
You can try mediation privately, through a community program if available, or through an online service like Judicaid for straightforward money disputes. That may be easier than planning multiple trips across a county where distance is a real issue.
What if the work was unfinished or defective?
Focus on proof, not anger. You generally want to show what was promised, what was actually delivered, and what it would reasonably cost to fix or finish the job.
Bad workmanship claims often turn on details. Take photos from different angles. Save packaging, receipts, inspection notes if you have them, and any expert opinion or replacement estimate. If the contractor promised one thing and delivered another, the most helpful evidence is usually the written agreement and photos.
Helpful evidence in an unfinished or defective work case
- The written contract or estimate
- Any change orders or messages approving extra work
- Before-and-after photos
- Photos of defects, incomplete areas, and materials left behind
- A second estimate for repair or completion
- Proof of payments already made
What if the contractor charged far more than quoted?
Look closely at whether the extra charges were approved. In many disputes, the core question is whether you agreed to changes in scope, materials, or timing before the bill increased.
A contractor may say the job changed. You may say the price was supposed to stay close to the estimate. The best proof is anything showing what each side knew and agreed to at the time: signed changes, text approvals, revised bids, or messages where one side objected.
If you are the contractor and the price increased for a legitimate reason, explain the reason in a timeline with documents. If you are the customer and you never approved the increase, say that clearly and ask the contractor to justify each added charge.
What if I am the contractor and the customer will not pay?
You still usually start with a demand letter and proof of the work performed. If the customer disputes quality, be ready to show photos, messages, invoices, and any sign-off showing the work was accepted or the extra work was requested.
Nonpayment cases often settle when the contractor presents a clean package: the agreement, work log, proof of materials, and a short explanation of what remains unpaid. If there was a punch-list or callback issue, it may be worth offering a limited fix in exchange for payment, especially when the amount in dispute is not huge.
Does it matter if the contractor was licensed?
Yes, it can matter a lot. In California, work above $1,000 generally requires a contractor license, which can affect leverage and how each side evaluates settlement.
If you are the customer, check whether the person you hired was properly licensed for the work. If you are the contractor, be careful about making claims you cannot support. Licensing issues can change how strong a case looks, so they often push people toward settlement.
Should I use small claims court or try to settle first?
Try to settle first if there is still a realistic path to agreement. Small claims is useful when the other side has stopped engaging, but settlement can save time, travel, and stress.
| Option | When it usually makes sense | Possible downside |
|---|---|---|
| Direct demand letter | You want a fast, low-cost first step and the other side may still respond | The other side may ignore it |
| Mediation | There is a real dispute but both sides might compromise on money or repairs | Both sides have to participate in good faith |
| Online negotiation with Judicaid | You want a structured settlement attempt without immediately going to court | It is still voluntary and does not force payment |
| Small claims | The dispute is mainly about money and settlement efforts failed | You may need to prepare carefully and deal with court scheduling |
| Walking away | The amount, proof, or stress makes further effort not worth it | You may recover nothing |
If your claim fits within the small claims limit for individuals, that limit is generally $12,500. But filing should usually come after you have tried a clear demand and considered whether the case could settle.
Where do I get help in San Bernardino County if I want to do this myself?
San Bernardino County has self-help resources that can make the process much less confusing. The county lists the Fontana Courthouse (17780 Arrow Boulevard) and the Victorville Courthouse (14455 Civic Drive, Suite 100), alongside San Bernardino, which matters in a county this spread out.
That local setup is important here. Because San Bernardino is the largest county in the contiguous United States by area, so the difference between the right and wrong district courthouse can be a two-hour drive, using the nearest appropriate self-help location can save a long trip just to ask a basic process question. If your dispute may head to small claims, you can also use the court's small claims email at smallclaims@sb-court.org for listed contact purposes, or call the civil information line at (909) 708-8678.
How long do I have to bring a contractor dispute?
It depends on whether your claim is based on a written or oral agreement. A written contract claim is generally 4 years, and an oral contract claim is generally 2 years.
Do not wait if you can avoid it. Evidence gets worse over time, people forget details, and unfinished work may get repaired by someone else, which can complicate proof. Even if you want to settle, it helps to act while documents and photos are still easy to organize.
What makes a contractor dispute more likely to settle?
Clear proof, a reasonable ask, and a practical solution. Most cases settle more easily when one side stops arguing in generalities and starts showing documents, photos, and a specific proposal.
- Write a short timeline of the job from estimate to breakdown.
- Attach the key documents, not every scrap of paper.
- Ask for one realistic outcome: pay the balance, refund part of the price, return to finish the job, or pay for repairs.
- Give the other side a way to say yes without admitting every allegation.
- If direct talks are going nowhere, consider mediation before filing.
In San Bernardino County, practicality matters. If the other side is in Victorville and you are in Chino, or you are in Redlands and the job site is in Fontana, distance can make in-person back-and-forth harder. A written settlement process is often better than endless calls.
Frequently asked questions
Can I sue a contractor in small claims in San Bernardino County?
Usually yes, if your dispute is mainly about money and fits the small claims rules. For individuals, the general small claims limit is $12,500, but you should usually make a demand first under Code of Civil Procedure § 116.320.
What if there was no written contract?
You may still have a case. Oral agreements can be enforced in many situations, but proof becomes more important, and the general time limit for an oral contract is 2 years.
Where can I get small claims help without driving all over the county?
San Bernardino County lists self-help resource centers at the Fontana Courthouse (17780 Arrow Boulevard) and the Victorville Courthouse (14455 Civic Drive, Suite 100), alongside San Bernardino. That matters because San Bernardino is the largest county in the contiguous United States by area, so the difference between the right and wrong district courthouse can be a two-hour drive, so choosing the nearest appropriate location can save a lot of time.
How do I contact the court about small claims information?
The county lists the civil division information line as (909) 708-8678. It also lists a small claims email at smallclaims@sb-court.org.
Does an estimate mean the contractor cannot charge more?
Not always. Extra charges may be valid if the scope changed and you approved it, but surprise charges are a common source of disputes, so the key question is usually what was actually agreed.
What if I already hired someone else to finish the job?
You can still often pursue the original dispute, but keep the records from the replacement contractor. Those documents may help show what it reasonably cost to complete or repair the work.
Is online mediation worth trying before court?
Often yes, especially when the dispute is about money, delay, or workmanship and both sides want to avoid more conflict. A service like Judicaid can be one settlement option at a flat price of $34.99, but it is still voluntary and does not guarantee a result.
This guide is general information, not legal advice, and Judicaid is not a law firm. Court fees, dollar limits, and procedures change — always verify current details with the San Bernardino County Superior Court (sb-court.org) or a licensed California attorney before acting.
