A Guide to California’s CSLB License Classifications
One agency every California contractor needs to be familiar with is the Contractors State License Board. This government agency determines who can perform contracting work and how, as well as establishes the rules and requirements for licensure. Learn more about the Contractors State License Board below, including types of contractor licenses, who needs licensure to work, and how to go about getting a license.
What Is the California Contractors State License Board (CSLB)?
The California Contractors State License Board (CSLB) is the governing agency for construction contractors in the state of California. The CSLB is a 15-member board with an appointed executive officer and approximately 400 employees that serve California. This agency regulates contractor licenses, policies, and requirements and handles complaints against contractors. The agency’s policies promote the health, safety, and general welfare of the public in construction matters. It’s the CSLB’s mission to protect the consumer public’s interests by overseeing that anyone charging over $500 per project for construction services is properly licensed and bonded.
What Does the CSLB Do?
The overarching function of the CSLB is setting the standards and requirements for license eligibility and seeing that contractors are fit for the work they intend to provide to prevent consumers from ending up with dishonest transactions and shoddy craftsmanship. The organization sets the standards and requirements for licensure, serves examinations, and upholds trade standards, ethics, and business practices. Should a contractor or entity work outside of regulations, the CSLB also enforces penalties, which often entails fines and license suspensions. Additionally, any advertising used by contractors is regulated by the CSLB.
What Are the Different Types of California Contractors Licenses?
There are four primary CSLB license classification groups: A: General Contracting, B: General Building, B-2: Residential Remodeling, and C: Specialty. The C-class license group is composed of approximately 45 specialized trade classifications.
Class A: General Engineering Contractors
General engineering contractors are those whose business is primarily in connection with fixed works requiring specialized engineering knowledge and skill in the following areas: irrigation, drainage, water power, water supply, flood control, inland waterways, harbors, docks and wharves, shipyards and ports, dams and hydroelectric projects, levees, river control and reclamation works, railroads, highways, streets and roads, tunnels, airports and airways, sewers and sewage disposal plants and systems, waste reduction plants, bridges, overpasses, underpasses and other similar works, pipelines and other systems for the transmission of petroleum and other liquid or gaseous substances, parks, playgrounds and other recreational works, refineries, chemical plants and similar industrial plants requiring specialized engineering knowledge and skill, powerhouses, power plants and other utility plants and installations, mines and metallurgical plants, land leveling and earthmoving projects, excavating, grading, trenching, paving and surfacing work, and cement and concrete works in connection with the above mentioned fixed works.
Class B: General Building Contractors
A general building contractor’s primary business relates to any structure built, being built, or to be built for the support, shelter, and enclosure of people, animals, chattels, or movable property and requires the use of at least two unrelated building trades or crafts. This does not include anyone who simply furnishes materials or supplies under Section 7045 without fabricating them into or consuming them in the performance of the work of the general building contractor.

Who Has to Be Licensed by the CSLB?
Any contractor operating within the state of California must be licensed by the CSLB in order to legally operate. The only exception is if the total cost of a construction process, including labor and materials, is less than $500. If the total cost of a project meets or exceeds $500, the contractor must hold the required California contractors licenses before submitting a bid.
Contractors must operate within the parameters of the license(s) held. Operating without or outside of a proper CSLB contractor license will result in possible fines, suspensions, or other disciplinary work bans. Courts can prohibit an unlicensed contractor from collecting monies owed for construction work, as well as require the contractor to pay back all monies received for work performed.
What Is the CSLB Licensing Process?
The first step in acquiring a CSLB contractor license is ensuring you meet the basic requirements, which include being at least 18 years of age, having the necessary skills to manage a construction business or be represented by someone who does, and have at least four years of verifiable journey-level or above construction-related experience.
If those requirements are met, you must then determine which license you’ll need (A, B, B-2, or C) and complete a licensure application with the CSLB. The CSLB will send a letter of acknowledgement when they receive your application. From there, it may take a few weeks to actually process your application. Once your application is approved, though, you’ll receive a notice to appear for the examination (or an exam waiver if applicable). You’ll then need to study for the exam, take and pass the exam, and wait for license approval. At that point, you’ll submit any final license requirements and be granted your contractor license.

In addition to proper licensure, contractors must also have the required surety bonds to perform work. In California, a $25,000 contractors license bond is required by the CSLB to protect the general public and ensure contractors follow state law in their business activities.
