What happens if you hire an unlicensed contractor

Last reviewed Oct 11, 2026. General information from official state sources, not legal or insurance advice.

An unlicensed contractor may quote a lower price, but the savings can disappear quickly. State licensing isn't just paperwork. It's tied to bonds, insurance and dispute programs that protect you. When you hire someone without a license, you usually give up those protections, and in some states you can take on an employer's legal duties yourself.

You lose the bond and the state's help

Licensed or registered contractors in many states must carry a surety bond that can pay homeowners for unfinished or faulty work. An unlicensed contractor doesn't have one.

Oregon: the Construction Contractors Board's hiring guide lists what you face with unlicensed contractors: "No source (bond) to reimburse you for poor workmanship." The CCB also says you lose its help mediating a dispute.
Washington: L&I explains that "required contractor bonds give homeowners some financial recourse if the job is left unfinished." The bond is $30,000 for general contractors and $15,000 for specialty contractors.
California: licensed contractors carry a $25,000 bond. An unlicensed contractor has none.

You may be treated as the employer

This is the risk most homeowners don't expect. If the person you hire brings workers, and that person isn't licensed, the law may treat you as their employer.

California: the CSLB's owner-builder pamphlet warns, "You may be considered an employer if you hire unlicensed contractors to do the work." Its list of employer duties includes "providing workers' compensation insurance." The CSLB adds that if uninsured workers are injured, "you could be asked to pay for injuries and rehabilitation through your homeowner's insurance policy or face lawsuits."
Washington: L&I says that if you hire someone who isn't a registered contractor, "you could be considered that person's employer, with wage, tax, workers' comp, safety, and record-keeping requirements." It also warns that "most homeowner policies do not cover workers."
Oregon: the CCB notes that unlicensed contractors may not have workers' compensation for injured employees, "potentially exposing you to liability."

Permits and inspections

Many projects need a building permit, and permit offices commonly expect a licensed contractor to pull it. California's owner-builder pamphlet puts it simply: "Any project needing a permit or workers requires a licensed contractor." If an unlicensed contractor talks you into pulling the permit yourself as an "owner-builder," you take on the responsibilities that come with that.

What happens to the contractor

States take unlicensed contracting seriously:

California: the CSLB lists penalties of "up to six months in jail and/or a $5,000 fine, as well as an administrative fine of $200 to $15,000," with a mandatory 90-day jail sentence for a second offense. Unlicensed contracting in a declared disaster area can be a felony.
Washington: working unregistered is a gross misdemeanor, with fines of $1,200 to $10,000 for failing to register (RCW 18.27.020, 18.27.340).
Oregon: civil penalties can reach $5,000 per offense (ORS 701.992).
Oklahoma: working as an unregistered roofer is a misdemeanor. The Construction Industries Board can fine individuals up to $500, and business entities face fines up to $5,000.

In several states, an unlicensed contractor also can't sue to collect payment. Oregon bars unlicensed contractors from filing construction liens or suing for compensation (ORS 701.131), and Washington requires registration to sue (RCW 18.27.080). California's CSLB says consumers aren't legally obligated to pay unlicensed contractors. Don't treat that as a reason to hire one. You'd still be giving up the protections above.

How to avoid the problem

Look up the contractor's license or registration with the state before you sign: CSLB in California, L&I in Washington, the CCB in Oregon, the CIB for Oklahoma roofers.
Confirm the license is active, not expired or suspended, and that the business name matches your contract.
Confirm the license type fits the job (for example, a roofing classification for a roof).
Ask for proof of insurance and verify it (see how to verify a certificate of insurance).
