Can an Unlicensed Contractor Sue You?

Burlingame, United States – June 26, 2026 / Furukawa Castles Karic LLP /

Discovering that a contractor was never licensed after work has already begun or finished puts homeowners in an uncertain position. When a contractor abandons your project or demands payment without holding a valid license, the legal picture changes significantly.

California’s contractor licensing laws provide meaningful protections that limit what an unlicensed contractor can pursue in court. In this press release, Furukawa Castles Karic LLP answers the question “Can an unlicensed contractor sue you?” and explains what homeowners should understand about their rights.

Can an Unlicensed Contractor Sue You?

In most cases, the answer is no. California Business and Professions Code Section 7031 generally bars an unlicensed contractor from recovering payment for work that required a valid license, even when that work was fully completed.

That prohibition is broad and applies regardless of whether the contractor performed the job correctly. Courts have consistently applied this rule, reflecting the state’s strong policy interest in enforcing licensing requirements.

What California Law Says About Unlicensed Contractors

California’s contractor licensing laws are among the strictest in the country, and the California Contractors State License Board (CSLB) is responsible for enforcing them. Any home improvement contract for work valued at $500 or more in combined labor and materials requires the contractor to hold a valid license before beginning the job.

Understanding why these requirements exist helps frame the protections they provide. Furukawa Castles Karic LLP notes that a contractor’s license bond is another reason licensing status matters before work begins. Unlicensed work can also create permit and documentation concerns later.

When an Unlicensed Contractor Claim May Be More Complicated

A few factors can influence how a payment dispute involving an unlicensed contractor is assessed in court:

Scope of the work: Whether the work performed actually required a license is typically the first question courts will examine.
Project value: If the work fell below the $500 licensing threshold, the contractor licensing requirement may not apply.
Nature of the license lapse: A license that expired due to an administrative error may be evaluated differently from one that the contractor never held.

These details are why homeowners should review the contractor’s licensing status before assuming how a payment dispute may be handled.

Risks San Francisco Homeowners Face When Hiring Without a License

Even when an unlicensed contractor cannot recover payment through the courts, hiring one still carries real exposure for homeowners. Under California Labor Code Section 2750.5, an unlicensed worker performing work that requires a contractor’s license may be presumed to be an employee rather than an independent contractor.

That classification carries consequences if someone is hurt on the job. Homeowners may face liability for injuries sustained during the project, particularly when workers’ compensation coverage is unavailable. Insurance coverage in these situations depends heavily on policy terms and the specific facts involved.
