California Fencing Contractor (C-13) License Practice Exam 2026 – Complete Study Guide

Contractor licensing in California is handled by the California Contractors State License Board. The CSLB is the state authority that issues and renews licenses, enforces license requirements, and maintains classifications such as C-13 for fencing. It operates under the California Department of Consumer Affairs, but the specific licensing function for contractors rests with the CSLB. The other agencies oversee unrelated areas—industrial relations focuses on workplace safety and labor standards, public health on health-related regulations—so they don’t administer contractor licenses.
