Contracting without a license in California is a misdemeanor punishable by up to $5,000 in fines and six months in county jail on a first offense, and the penalties climb from there. The contractor also loses the right to sue for payment and can be ordered to refund everything the homeowner already paid, even for finished work. Homeowners who hire unlicensed workers carry their own exposure, which most never see coming.
First-Offense Criminal Penalties
Under Business and Professions Code 7028, a first conviction for working as a contractor without a valid license carries a fine of up to $5,000, up to six months in county jail, or both.1California Legislative Information. California Business and Professions Code 7028 Prosecutors push harder when there’s evidence of consumer harm or deceptive advertising, and misrepresenting license status to a homeowner turns an otherwise straightforward case into one the district attorney will take to trial.
Using another contractor’s license number is a separate offense under Business and Professions Code 7027.3. It can be charged as a felony with up to three years in prison. It’s a common shortcut that carries wildly disproportionate consequences compared to simply working without any license at all.
Second, Third, and Post-Revocation Offenses
A second conviction triggers a mandatory fine equal to 20 percent of the contract price or $5,000, whichever is greater. The default jail term is at least 90 days, and a judge who goes below that has to state the reasons on the record.1California Legislative Information. California Business and Professions Code 7028
A third or subsequent conviction carries a fine between $5,000 and either $10,000 or 20 percent of the contract price, whichever is greater, plus a mandatory jail sentence of 90 days to one year. These penalties are cumulative with penalties under other California laws, so the court can stack charges.1California Legislative Information. California Business and Professions Code 7028
Anyone whose contractor license was previously revoked, and who was responsible for the acts that led to the revocation, lands in the third-offense tier automatically on their first charge after revocation.1California Legislative Information. California Business and Professions Code 7028
Charges That Can Be Stacked On Top
Unlicensed contracting rarely stays a single-charge case when something goes wrong. If payments collected for the work exceed $950, prosecutors can add grand theft under Penal Code 487, which is a wobbler chargeable as either a misdemeanor or a felony depending on the circumstances.2California Legislative Information. California Penal Code 487
Targeting homeowners aged 65 or older adds another layer. Penal Code 368 covers financial crimes against seniors, and when the value taken exceeds $950 the offense becomes a wobbler with potential felony punishment of two, three, or four years in state prison and fines up to $10,000.3California Legislative Information. California Penal Code 368 Door-knocking in senior neighborhoods after a storm is exactly the profile prosecutors build elder abuse cases around.
Contracting without a license inside a declared state or federal disaster area can be charged as a felony, which means potential state prison time rather than county jail.4Contractors State License Board. Consequences of Contracting Without a License Opportunistic repair work following wildfires, earthquakes, or floods is treated as the aggravated version of the offense.
Losing the Right to Be Paid
The civil side is what tends to shock contractors. Under Business and Professions Code 7031, an unlicensed contractor cannot file suit to collect payment for work performed, no matter how well the project turned out. Even if the homeowner is happy with the finished product and simply refuses the final installment, the contractor has no legal remedy.5California Legislative Information. California Business and Professions Code 7031
It gets worse. The property owner can sue to recover every dollar already paid, even for completed, satisfactory work. Under this disgorgement rule, a contractor who finished a $60,000 kitchen can be ordered to hand back the full $60,000. California courts enforce the statute without much sympathy for the contractor’s side of the story. Any security interest taken to guarantee payment is also unenforceable, and a mechanic’s lien filed by an unlicensed contractor is worthless.5California Legislative Information. California Business and Professions Code 7031
The Substantial Compliance Exception
There is one narrow escape. A court can find “substantial compliance” with the licensing requirements, but only if the contractor was previously licensed in California, acted in good faith to maintain that license, and moved quickly to fix the lapse once they discovered it. Someone who has never held a California contractor license cannot use this defense at all.5California Legislative Information. California Business and Professions Code 7031 In practice, it protects a licensed contractor whose renewal payment was late or lost in the mail, not someone who deliberately avoided getting licensed.
What Homeowners Risk by Hiring Unlicensed
California does not put all the risk on the contractor. Under Labor Code 2750.5, there is a legal presumption that a worker performing services requiring a contractor’s license is an employee, not an independent contractor, if they don’t hold a valid license.6California Legislative Information. California Labor Code 2750.5 That presumption has teeth.
If the unlicensed worker or anyone on their crew is injured on the job, the homeowner can be treated as the employer for workers’ compensation purposes. California requires workers’ compensation coverage for anyone with even one employee.7Contractors State License Board. Workers’ Compensation Requirements A homeowner who never intended to be anyone’s boss can suddenly owe medical bills, lost wages, and disability payments for a worker they barely supervised. If the worker is reclassified as an employee for tax purposes under the IRS framework, the homeowner can also owe unpaid employment taxes, Social Security, and Medicare contributions.8Internal Revenue Service. Worker Classification 101: Employee or Independent Contractor
The protections that come with hiring a licensed contractor disappear too. Licensed contractors carry a $25,000 surety bond and a separate $25,000 bond for their qualifying individual, and consumers can file claims against those bonds when work is abandoned or defective.9Contractors State License Board. Bond Requirements An unlicensed operator has nothing of the kind. Standard commercial general liability policies often exclude work performed without proper licensing, and claims arising from unlicensed activity are routinely denied. The homeowner’s own property insurance may also deny claims for damage caused by unpermitted or unlicensed construction.
When a License Isn’t Required
Not every construction job in California needs a licensed contractor, but the exemptions are narrower than people assume, and misunderstanding them is one of the most common ways people cross the line.
Minor Work Under $1,000
As of January 1, 2025, Assembly Bill 2622 raised the minor work exemption from $500 to $1,000. A person can perform work without a license if the total cost of labor, materials, and every other expense is under $1,000. The job cannot require a building permit of any kind, and the person cannot hire anyone to help.10Contractors State License Board. License Requirement for Minor Work Increases from $500 to $1,000 If the work needs a permit or involves any paid help, a license is required regardless of price. Breaking a larger project into smaller pieces to stay under the threshold is explicitly prohibited.11Contractors State License Board. Before Applying for a License When No Exam is Required
Owner-Builders
Property owners can build or improve structures on their own land without a license under Business and Professions Code 7044. If the owner does the work personally or uses their own employees, the improvements are not intended for sale, and no subcontractors are involved, no license is required.12California Legislative Information. California Business and Professions Code 7044
An owner can also hire licensed subcontractors directly for specific trades. For single-family homes, this arrangement allows the sale of up to four structures per calendar year. A homeowner improving their primary residence qualifies as long as they have lived there for at least 12 months before the work is completed and the work is done before any sale.12California Legislative Information. California Business and Professions Code 7044
Selling or offering a structure for sale within one year of completion creates a legal presumption that the project was built for sale, which defeats the exemption. Selling five or more structures within a year makes that presumption conclusive and impossible to rebut.12California Legislative Information. California Business and Professions Code 7044
Licensed architects and engineers working within the scope of their professional license don’t need a separate contractor’s license. Government employees working on public projects and certain agricultural workers in farm-related construction are also exempt.
How the CSLB Catches Unlicensed Work
The Contractors State License Board investigates unlicensed activity through consumer complaints, undercover sting operations, and job-site inspections.13Contractors State License Board. Consumer Home Page The CSLB coordinates with local law enforcement and district attorneys, and it can issue stop-work orders on the spot. Citations go into a public database that anyone can search, which creates a real obstacle for anyone hoping to get licensed later. Repeat or egregious violations are referred to county prosecutors for criminal charges, and the Board runs regular sting operations in areas affected by natural disasters, where unlicensed operators tend to concentrate.
