California C-16 fire protection license

As of Nov 4, 2026. Rules change, so confirm with the agency before you apply. Numbers in brackets link to the official source for each fact.

What the C-16 covers

A C-16 contractor lays out, fabricates and installs all types of fire protection systems and their equipment, but not electrical alarm systems. ^[1]

State law (B&P Code 7026.12) says fire protection system installation, excluding electrical alarm systems, must be done by a contractor holding the fire protection classification. ^[2]

Under B&P Code 7057(c), a general building (B) contractor can't take a contract that includes C-16 work unless it holds the C-16 or subcontracts that work to a properly licensed specialty contractor. ^[2]

The C-16 trade exam

CSLB's study guide weights the trade exam this way: Planning and Estimating 25%, Installation of Underground Fire Main Systems 9%, Installation of Fire Protection Systems 36%, Maintenance and Repair 9%, and Safety 21%. CSLB notes the percentages are approximate. ^[3]

What this means for job seekers

The C-16 is a contractor license held by the business through a qualifying person. Most fitters and techs work for a C-16 contractor rather than holding the license themselves. Fire alarm work falls outside the C-16.
