California 
You're required to be licensed by the California Contractors State License Board (CSLB) if the total cost of one or more contracts on the project is $500 or more.


California has three contractor classifications, General Engineering Contractor, General Building Contractor and Specialty Contractor.

Two specialty contracting classifications commonly used by wireless contractors are Structural Steel Contractor and Low Voltage Systems Contractor.

In 2018, the low voltage license classification was surgically dissected in a lawsuit.

The 2019 California Contractors License Law & Reference Book is AVAILABLE HERE.

In Ayn Rand’s fictional novel, Atlas Shrugged, she depicted a dystopian United States in which private businesses suffer under increasingly burdensome laws and regulations. To best her 1,168-page novel, California’s Contractors License Board published their latest 2019 edition of contractors’ license law, a contractor’s must-read of 1,201 pages. In short, California requires a license for almost any discipline you can think of performing including professional skill sets and cottage-industry crafts that haven't been thought of yet.
