Questions about hiring a commercial GC

Which contractor license does a commercial build-out need?

A B (General Building) license. The B definition covers any structure for people or property and does not split homes from businesses. A B-2 license is limited to existing residential wood-frame buildings, so a B-2 contractor cannot take a store or office build-out. Fire sprinkler work needs a C-16 license or a licensed C-16 subcontractor (CSLB, B&P Code 7057).

Does a commercial contractor need workers' comp?

Any contractor with employees must carry workers' comp. A contractor with no employees can file an exemption, and a card marked exempt means the contractor told CSLB it has no employees. Ask who will work on your site. From January 1, 2028 California requires a workers' comp certificate for every license, with a narrow joint-venture exception (CSLB, checked Oct 18, 2026).
