Quick answer
Construction litigation in California covers disputes that arise on building projects, including claims for defective work, unpaid bills, project delays, and disagreements over what a contract requires. California has specific notice rules that apply to many construction defect claims, meaning you may be required to notify the other side in writing and allow time for a response before filing a lawsuit. Deadlines to take legal action can be short and vary depending on the type of dispute and who is involved, so acting quickly is essential. If you are facing a construction dispute, speaking with a California attorney or a local legal-aid organization as soon as possible is strongly recommended.

How to take action in California
- 1
Gather and preserve all documentation
Collect your contract, any change orders, photos, inspection reports, receipts, emails, and all written communications related to the project. Strong documentation is the foundation of any construction dispute.
- 2
Review your contract carefully
Your contract may spell out exactly how disputes must be handled, including whether you are required to attempt mediation or arbitration before going to court. Understanding these terms early can shape every step that follows.
- 3
Send a written notice of the problem
California law often requires that a property owner give the contractor formal written notice of a defect and allow a reasonable opportunity to respond before a lawsuit may be filed. An attorney can help you follow this process correctly so your claim is not affected.
- 4
Verify that the contractor is properly licensed
The California Contractors State License Board licenses and regulates contractors who perform construction work in the state. If a contractor you hired was unlicensed, that can significantly affect your legal options, including how you may recover damages.
- 5
Explore mediation or arbitration
Many construction contracts require the parties to try alternative dispute resolution before going to court, and even when it is not required, these approaches can resolve disputes more quickly and at less cost than a trial.
- 6
Consult a California construction attorney promptly
Construction disputes involve technical rules about notice, licensing, payment security tools, and deadlines that are easy to miss without legal guidance. See the deadlines section of this page and speak with an attorney as soon as possible.

Common questions about construction litigation in California
What is a construction defect under California law?
A construction defect is broadly any condition on a property that results from a failure to meet the applicable standard of care during design, construction, or materials selection. In California, defects can range from structural problems and water intrusion to electrical and mechanical failures. Not every imperfection rises to the level of a legal defect, and whether a particular condition qualifies often depends on expert evaluation. If you believe your property has a construction defect, documenting it thoroughly and consulting an attorney are important first steps.
What is a mechanics lien and how does it work in California?
A mechanics lien is a legal tool that allows a contractor, subcontractor, or materials supplier who has not been paid for work or materials to place a formal claim against the property where the work was performed. California has specific rules about timing and written notice that must be followed for a lien to be valid. A lien can cloud a property's title and may ultimately lead to a court action if the underlying dispute is not resolved. Property owners who receive a preliminary notice from a contractor or supplier should pay attention, because that document is an early step toward a potential lien claim.
Do I have to give the contractor a chance to fix the problem before suing in California?
For many residential construction defect claims in California, the law requires a homeowner to follow a pre-litigation process that includes giving the contractor written notice and an opportunity to inspect the defect and propose a remedy. This requirement is designed to encourage resolution without court involvement and applies to a broad range of residential construction defects. Skipping this step can affect your ability to proceed with a lawsuit. An attorney can help you determine whether this process applies to your situation and guide you through it correctly.
What does the Davis-Bacon Act require, and does it apply in California?
The Davis-Bacon Act is a federal law that applies to most construction projects funded in whole or in part by the federal government. It requires that workers on covered projects be paid at least the prevailing wage rate for their trade in the area where the work is performed, as determined by the U.S. Department of Labor. Violations can lead to back-pay obligations and other consequences for contractors. If you are a worker on a federally funded project in California and believe you were paid less than the required rate, consulting an attorney who handles wage claims can help you understand your options.
Can a subcontractor or supplier place a claim against my property even if I paid my general contractor?
In California, subcontractors and materials suppliers who are not paid by a general contractor may be able to file a mechanics lien against the property even though the property owner had no direct contract with them. This means a property owner can face a lien claim after having paid the general contractor in full, if that contractor failed to pay those further down the chain. Property owners can reduce this risk by requiring written lien releases from subcontractors and suppliers as payments are made. Speaking with an attorney before and during a project can help you put these protections in place.
What does the California Contractors State License Board do?
The California Contractors State License Board is the state agency responsible for licensing and regulating contractors who perform construction work in California. The board sets licensing requirements, investigates consumer complaints, and can discipline or revoke the license of contractors who violate the law or engage in fraudulent conduct. Most construction work above a relatively modest value legally requires a licensed contractor, and working with an unlicensed one can create serious complications if a dispute arises. You can check a contractor's license status with the board before hiring.
Is it better to go to court or use mediation or arbitration for a construction dispute in California?
The right approach depends on what your contract requires, the nature of the dispute, and your specific goals. Many California construction contracts include clauses that require mediation or arbitration before a lawsuit may be filed, so court may not be available until those steps are completed. Alternative dispute resolution can be faster and less costly than litigation, but court proceedings offer certain procedural protections and the right to appeal decisions. An attorney familiar with California construction law can help you evaluate which path fits your situation.
