What Is a C-8 Concrete Contractor License?
The C-8 Concrete Contractor classification is one of the Contractors State License Board’s core specialty licenses, and it covers more of the built environment than most applicants expect. According to the CSLB’s official classification description, a C-8 contractor “forms, pours, places, finishes and installs specified mass, pavement, flat and other concrete work; and places and sets screeds for pavements or flatwork.”
The classification has clear limits. It does not cover contractors whose business is solely the application of plaster coatings, and it does not cover the placing and erecting of steel or reinforcing bars for concrete work, which fall under separate classifications. The C-8 classification is established under California Code of Regulations, Title 16, Division 8, Article 3, with its authority cited from Business and Professions Code Sections 7008 and 7059.
In practice, C-8 contractors pour foundations, slabs, driveways, sidewalks, patios, and pavement, which makes the license relevant to residential, commercial, and public works concrete scopes alike.
C-8 License Requirements
To qualify for the C-8 exam, CSLB requires that you:
- Be at least 18 years of age
- Have a minimum of four full years of experience at the journey level, or as a foreman, supervisor, or contractor, in the concrete trade within the ten years before you apply
- Pass both required examinations (see below)
CSLB does allow certain formal education to be credited toward part of the experience requirement in some cases. Because the specific credit varies by program and by classification, confirm your own eligibility directly with CSLB before assuming any education substitutes for hands-on experience.
Bond and Insurance Requirements
Every CSLB licensee, regardless of classification, must maintain a $25,000 contractor bond. This amount increased from $15,000 effective January 1, 2023, under Senate Bill 607, so if you are working from an older guide or a friend’s experience from a few years ago, the number you remember is out of date.
If your license will be qualified by a Responsible Managing Employee (RME), or by a Responsible Managing Officer (RMO) who owns less than 10 percent of the corporation’s voting stock, CSLB also requires a separate $25,000 Bond of Qualifying Individual (BQI), effective the same date. RMOs who own 10 percent or more of the voting stock are exempt from the BQI requirement.
You will also need to meet CSLB’s workers’ compensation insurance requirements once you have employees, and submit Live Scan fingerprints as part of your application.
C-8 License Fees
Per CSLB’s current published fee schedule:
- Application fee: $450 (non-refundable, covers exam or waiver review for one classification)
- Initial license fee: $200 for a sole owner, $350 for a non-sole owner (corporation, LLC, or partnership)
These are CSLB’s fees only. Your total cost also includes your bond premium, any BQI premium if applicable, Live Scan fees, and workers’ compensation insurance once you have employees.
The C-8 Exam Structure
Like every CSLB classification, the C-8 license requires passing two separate exams: the Law and Business exam, which is the same exam every CSLB applicant takes regardless of classification, and the C-8 Trade exam, which covers concrete-specific scopes of work, materials, and safety practices. Both are administered as computer-based, multiple-choice tests. Question counts and time limits are set by CSLB and detailed in your classification-specific candidate handbook once your application is approved, so confirm the current specifics directly with CSLB or in your official study materials rather than relying on secondhand numbers.

Who Needs a C-8 License?
General contractors and developers who need foundations, slabs, or flatwork poured on a job; homeowners building driveways, patios, or pool decks; and concrete-only companies bidding public-works paving, curb, and gutter work all rely on a licensed C-8 contractor.
Frequently Asked Questions
What work can a C-8 contractor do that other licenses cannot?
A C-8 contractor forms, pours, places, and finishes mass, pavement, flat, and other concrete work, and sets screeds for pavement or flatwork. It does not cover plaster-only contracting or placing reinforcing steel or bars, which are separate classifications.
How much does it cost to get a C-8 license in total?
CSLB’s direct fees are $450 for the application and $200 (sole owner) or $350 (non-sole owner) for the initial license, plus your $25,000 bond premium (and a separate BQI premium if your qualifier is an RME or a minority-owner RMO), Live Scan fees, and workers’ compensation once you have employees. Bond premiums vary by credit and business history.
How long does it take to get a C-8 license?
Timing depends on how quickly you document your four years of qualifying experience, schedule and pass both exams, and CSLB’s current processing volume. There is no fixed CSLB timeline, so build in time for experience verification and exam scheduling when you plan your application.
Can I hold a C-8 license alongside a General B license?
Yes, you can qualify for and hold multiple classifications on one license, including B and C-8 together, as long as you meet the experience and exam requirements for each classification you add.
Does my four years of experience have to be in California?
CSLB evaluates experience based on the work performed and who can verify it, not strictly where it occurred, but out-of-state experience still needs a qualified person to verify it in the same way in-state experience does. Confirm how CSLB will treat your specific work history before you apply.
Does a C-8 contractor pour building foundations?
Yes — mass concrete and foundation flatwork fall within the classification’s “forms, pours, places, finishes” scope. Placing or tying reinforcing steel is generally C-50 (Reinforcing Steel) scope, though CSLB allows incidental work reasonably necessary to complete a C-8 contractor’s own concrete scope.
Can a C-8 contractor also do decorative or stamped concrete finishing?
Yes. “Finishes” in the classification’s regulatory language covers surface treatment of the pour, which includes stamped, exposed-aggregate, and other decorative concrete finishing techniques, not just utilitarian flatwork.
