Business Organization & Licensing
This chapter explains how California contractor licenses are organized: the classification system, who must qualify a license, how a business can legally be structured, the bonds every licensee carries, and what the CSLB can do when the rules are broken. Master these topics and you have covered roughly one out of every eight exam questions.
License Classifications: A, B, and C
California sorts contractor work into three license classes. Class A, General Engineering, is for fixed works that require specialized engineering knowledge, such as roads, bridges, dams, sewers, and pipelines. Class B, General Building, is for projects that require at least two unrelated building trades or crafts, or that involve framing or carpentry on a structure intended for human use. Class C is the Specialty group, made up of 43 separate classifications, each limited to a single trade such as C-10 Electrical, C-36 Plumbing, or C-39 Roofing. A business may hold more than one classification, but each one is applied for, examined, and qualified separately.
When Each Class Applies
Choosing the right class is more than a formality. A General Building (B) contractor may take a prime contract for a structure only when the job needs two or more unrelated trades, or includes framing; for a single-trade job the B contractor must either hold the matching C license or subcontract that work to a properly licensed specialist. A specialty (C) contractor may not act as a general builder by stringing together unrelated trades. General Engineering (A) work and General Building (B) work are genuinely different scopes, so a contractor needs the class that actually matches the project.
The Qualifying Individual and the Experience Requirement
Every license is tied to a Qualifying Individual, the person whose knowledge and experience legally support it. To qualify, that person must show at least four years of journey-level, foreman, supervisor, or contractor experience within the trade during the ten years before applying. Journey-level means fully trained and able to perform the work without supervision. Credit may also be granted for certain technical training, apprenticeship, or education, but at least one year must be practical hands-on experience. The Qualifying Individual must pass both the Law and Business exam and the trade exam for the classification.
RMO vs. RME: Two Ways to Qualify a License
The Qualifying Individual serves in one of two roles. A Responsible Managing Officer (RMO) is an owner of the business: an officer of a corporation, a manager or member of an LLC, or a general partner, and for these purposes owns at least 20 percent of the company. A Responsible Managing Employee (RME) is a bona fide employee who holds no ownership stake. The key limit is that an RME may qualify only one active license at a time, while an RMO may, with CSLB approval, qualify more than one. In every case the qualifier must be genuinely involved in supervising and directing the company's construction operations, not just lend a name.
Eligible Business Entities
A California contractor license may be issued to four kinds of legal structure. A sole owner license belongs to one individual. A partnership license belongs to two or more general partners. A corporation license is held by the corporation itself and qualified by an officer. A limited liability company (LLC) may also hold a license, with extra insurance and worker requirements attached. A trust cannot hold a contractor license. Whichever structure is chosen, the entity, not the qualifying person, is the licensee, and the license cannot be sold or transferred to anyone else.
Changing the Business Entity
A contractor license is issued to one specific legal entity, so it does not automatically follow the business through structural changes. If a sole owner incorporates, if a corporation converts to an LLC, or if the legal form of the business otherwise changes, a brand-new license application is required because a new legal entity now exists. The same is true for a partnership when partners are added or removed: any change in the lineup of partners dissolves the old partnership in the eyes of the law and a new application must be filed. Limited continuation rights exist in narrow situations, but the safe assumption for the exam is that a changed entity needs a new license.
The Contractor License Bond
Every active license must be backed by a contractor license bond in the amount of $25,000. This bond is consumer protection: it does not protect the contractor or guarantee the contractor's work like an insurance policy would. Instead, it gives certain injured parties, mainly homeowners harmed by a violation of the license law, an employee owed wages, or a subcontractor or supplier left unpaid, a source to file a claim against. If the bond lapses, is cancelled, or is exhausted by claims, the license is suspended until the bond is restored.
Bond of Qualifying Individual and the Disciplinary Bond
Beyond the basic license bond, two other bonds appear on the exam. A Bond of the Qualifying Individual, in the amount of $25,000, is required when the qualifier is an RMO who owns less than 10 percent of the company, or an RME; it covers the same kinds of claims as the license bond and reflects the fact that the qualifier does not own the business outright. Separately, a $15,000 disciplinary bond can be ordered by the CSLB as a condition of issuing, reinstating, or maintaining a license after the contractor has a history of discipline, unpaid claims, or unsatisfied judgments. The disciplinary bond is a safeguard against repeat misconduct.
Displaying the License Number; Advertising
A licensed contractor must show the license number in a consistent way. The number must appear on all contracts, bids and proposals, business cards, and all advertising, including websites and print and online ads. It must also be displayed on each commercial vehicle used in the business. Anyone who advertises for or solicits construction work that requires a license must either hold that license or, if unlicensed, clearly state in the ad that they are not licensed and may only do work under the small minor-work threshold. Advertising for licensed-level work without a license is itself a violation.
Fictitious Business Names and DBAs
Many contractors operate under a name different from the owner's legal name or the registered corporate name; this is a fictitious business name, often called a DBA (doing business as). The name a contractor actually uses with the public must be registered with the CSLB and listed on the license itself. Filing a DBA with the county is a separate local step and does not satisfy the CSLB requirement. Using a business name that is not on file with the CSLB, or that is misleading, can lead to citation and discipline.
Subcontracting and Verifying Licensure
A prime contractor who hires subcontractors is responsible for using only properly licensed firms for work that requires a license. Hiring an unlicensed subcontractor exposes the prime contractor to discipline and to liability, because an unlicensed person performing licensed-level work is treated as an employee for purposes of payroll, taxes, and injuries. Verifying a subcontractor's status is easy and free through the CSLB online license check, and it should be done before the work starts and confirmed that the license is active and carries the correct classification.
CSLB Discipline, Renewal, and the Unlicensed Bar
The CSLB enforces the license law along a scale of severity: an advisory notice is an informal, private warning; a citation is a formal order with a fine and an order of correction; suspension makes the license temporarily inactive so no work may be done; and revocation cancels the license permanently, forcing the contractor to reapply from scratch. Citations are disclosed to the public on the CSLB license lookup for five years. Operating without a license is serious: an unlicensed contractor cannot sue to collect payment for work that required a license, and a customer can even sue to recover money already paid. The only narrow relief is the minor-work exemption, for jobs where the combined labor and materials total less than $500 and no license is otherwise required. Licenses must be renewed every two years, and a license that has been expired for five years can no longer be renewed at all, requiring a fresh application and examination.
