PSI Practice questions for your California C21 Exam
What Is the California C21 License?

The California C21 License is a contractor license issued by the California State License Board (CSLB) for building moving/demolition contractors. According to the CSLB classification definition:

A building moving/demolition contractor raises, lowers, cribs, underpins, demolishes, and moves or removes structures, including their foundations. This classification does not include the alterations, additions, repairs, or rehabilitation of the permanently retained portions of such structures.

The C21 demolition license is in high demand due to the ongoing need for safe demolition and removal of hazardous or burnt structures in California. As a C21 license holder, your role is both essential and sought-after.

C21 License Requirements

To qualify for the C21 demolition license California requires, you must:

  • Be at least 18 years old
  • Have the experience and skills to perform building moving/demolition operations
  • Submit a completed application and pay all fees (read more here)
  • Pass two exams: the trade exam (C21) and the California business law exam (business law exam practice test)
  • Undergo a background check

For further frequently asked questions, consult the CSLB Examinations FAQ.

What Does a C-21 License Holder Do?

C-21 license holders tackle high-stakes projects that demand precision and safety. Typical work includes demolishing old buildings, moving structures to new sites, and clearing debris from disaster areas like wildfire zones. In California, where environmental regulations are strict, these professionals must adhere to guidelines for waste management and site restoration. For instance, safely removing burnt structures requires expertise in handling hazardous materials, making this license invaluable in today’s climate.

If you’re passionate about construction safety and demolition, pursuing a C21 license opens doors to specialized contracts. It’s not just about breaking things down—it’s about doing so responsibly.
