California B&P Code: Licenses, Prohibited Conduct & Discipline

The California Business and Professions Code sets the licensing requirements for regulated professions and industries in the state, defines conduct like false advertising and unfair competition as illegal, and gives dozens of state boards the authority to investigate violations and impose penalties. Depending on the offense, those penalties range from administrative citations of up to $5,000 per inspection to felony charges carrying state prison time.

Who Has to Follow the Code

The code applies to anyone engaged in a regulated profession or commercial activity in California. That covers licensed professionals like doctors, attorneys, real estate agents, and contractors, and industries such as cosmetology, automotive repair, and private security. Corporations, partnerships, LLCs, and sole proprietors all fall under it when they do work the code regulates. People who aren’t licensed but perform work that requires a license are covered too, along with professional fiduciaries, advertisers, and out-of-state companies serving California consumers.

Enforcement is spread across dozens of boards and bureaus inside the Department of Consumer Affairs. The Medical Board oversees physicians. The Contractors State License Board handles construction. The Department of Real Estate regulates brokers and salespersons. Each board runs its own complaint intake and discipline process, but all operate under the same statutory framework.1Department of Consumer Affairs. Department of Consumer Affairs

Licenses and Permits You Need Before Operating

Every regulated profession has its own licensing requirements, but the common ingredients are exams, education, experience, background checks, and fees.

Attorneys must be at least 18, hold a law degree from an accredited or approved school (or complete an equivalent course of study), show good moral character, and pass the California Bar Exam.2California Legislative Information. California Code BPC 6060 – Admission to Practice Law Contractors must show knowledge and experience in their trade classification, pass a licensing exam, and have a qualifying individual appear before the Contractors State License Board.3California Legislative Information. California Code BPC 7068 – Contractor Qualifications Contractors also need a $25,000 surety bond to obtain or maintain a license.4Contractors State License Board. Bond Requirements

Some industries need operational permits from specialized agencies rather than a professional license. Selling alcohol requires a license from the Department of Alcoholic Beverage Control, which can refuse to issue one if the applicant has violated the Alcoholic Beverage Control Act or has a disqualifying criminal record.5Alcoholic Beverage Control.

California Code BPC 26038 – Unlawful Cannabis Activity

Licenses don’t last forever. Most require periodic renewal, and many professions tie renewal to continuing education. Miss a renewal and the license expires; getting it back can mean reapplying from scratch, sometimes including retaking exams.

Conduct the Code Prohibits

Three categories draw most of the enforcement action: false advertising, unfair competition, and unlicensed practice.

False Advertising

Section 17500 makes it illegal to make or spread any statement about goods, services, or property that is untrue or misleading if the person knew or should have known it was false. It applies across every medium, from print to social media to verbal claims. Intent to defraud isn’t required. If your claim could mislead a reasonable consumer and you failed to exercise reasonable care in verifying it, you’re exposed.7California Legislative Information. California Code BPC 17500 – False Advertising Courts can order injunctions and require the return of money or property consumers lost.8California Legislative Information. California Code BPC 17535 – Injunctive Relief

Unfair Competition

Section 17200, the Unfair Competition Law, is one of the broadest consumer protection statutes in the country. It covers any unlawful, unfair, or fraudulent business practice, along with deceptive or misleading advertising.9California Legislative Information. California Code BPC 17200 – Unfair Competition Defined The “unlawful” prong is the powerful part: a violation of almost any other law can serve as the basis for an unfair competition claim. Price-fixing, bait-and-switch schemes, and deceptive billing all qualify. Prosecutors don’t need to prove any individual consumer was harmed; the conduct itself is enough. Civil penalties reach $2,500 per violation, with courts weighing seriousness, number of violations, duration, and intent.10California Legislative Information. California Code BPC 17206 – Civil Penalties

Unlicensed Practice

Working in a regulated profession without a license is one of the most aggressively enforced violations, and consequences depend heavily on the profession. Practicing medicine without a license carries a fine of up to $10,000, county jail for up to one year, or state prison.11California Legislative Information. California Code BPC 2052 – Unlicensed Practice of Medicine Practicing law without active State Bar membership is a misdemeanor with up to one year in jail and a $1,000 fine, with a mandatory 90-day minimum on a second conviction. A disbarred or suspended attorney who continues practicing can face state prison.12California Legislative Information. California Code BPC 6126 – Unauthorized Practice of Law

Unlicensed contractors face an escalating criminal structure and a brutal civil rule. On the civil side, any customer who hired an unlicensed contractor can sue to recover every dollar paid. The contractor has no right to keep any compensation for the work, no matter how well it was done.13California Legislative Information. California Code BPC 7031 – Recovery of Compensation

Penalties by Violation Type

What the code actually prescribes for the most commonly enforced offenses:

Repeat offenders and people involved in large-scale fraud face enhanced penalties, including asset forfeiture and permanent restrictions on business activity. Courts regularly order restitution alongside fines and jail time.

How Investigations and Discipline Work

Enforcement begins with the individual board that oversees the profession. Investigations start from consumer complaints, referrals from other agencies, audits, and sometimes proactive sting operations. Investigators can inspect business premises, interview witnesses, subpoena records, and coordinate with law enforcement. Minor violations may be handled by administrative citation rather than formal discipline.

When a board substantiates a violation, its options include probation (sometimes with conditions like ethics training or supervision), suspension, revocation, or administrative fines. Citations can carry fines of up to $5,000 per inspection or investigation, with the amount based on the gravity of the violation, the licensee’s good faith, and past history.16California Legislative Information. California Code BPC 125.9 – Citations and Fines

If you’re facing formal discipline, you have the right to contest the allegations at an administrative hearing before an administrative law judge. The board files an accusation, and the case proceeds under the Administrative Procedure Act. The standard is preponderance of the evidence, meaning the board must show it’s more likely than not that the violation occurred.17Legal Information Institute. 4 CCR 12554 – Formal Hearing Process In urgent cases where letting the licensee keep working would endanger the public, a board or an administrative law judge can issue an interim suspension order while the case is pending.18California Legislative Information. California Code BPC 494 – Interim Suspension Orders

Criminal Records and License Eligibility

A criminal conviction doesn’t automatically bar you from a professional license. A board may deny an application based on a conviction only if the crime occurred within the past seven years and is substantially related to the duties of the profession. Convictions older than seven years generally cannot be the basis for denial.19California Legislative Information. California Code BPC 480 – Criminal Conviction and License Denial

Two exceptions override that seven-year limit: serious felonies as defined in the Penal Code, including sex offenses requiring registration, and financial crimes classified as felonies that directly relate to fiduciary duties in professions like contracting, real estate, and private investigation. Outside those exceptions, a board cannot deny your license based on a conviction that has been dismissed or expunged, and applicants with a certificate of rehabilitation or a pardon are also protected.19California Legislative Information. California Code BPC 480 – Criminal Conviction and License Denial

Separately, a board can deny a license if the applicant made a knowingly false statement on the application, committed fraud or dishonesty intended to benefit themselves or harm another, or committed an act that would be grounds for discipline if they were already licensed.20California Legislative Information. California Code BPC 475 – Grounds for License Denial

Filing a Complaint or Verifying a License

If you suspect a business or professional is violating the code, you can file a complaint through the Department of Consumer Affairs, which oversees the licensing boards. The department also runs a public license verification tool that lets you confirm whether someone holds an active, valid license.1Department of Consumer Affairs. Department of Consumer Affairs Checking a contractor’s license through the Contractors State License Board or a doctor’s credentials through the Medical Board before hiring is one of the simplest protections available. If someone can’t give you a license number, treat it as a red flag.
