Overview
Do you need a California general contractor license?
Yes, if you contract general building or general engineering work in California. The Contractors State License Board (CSLB) issues these licenses, and every licensed contractor must keep a contractor’s bond on file.
License required when
- You contract work on structures that need at least two unrelated building trades (B General Building)
- You contract infrastructure and other fixed works that need specialized engineering knowledge and skill (A General Engineering)
- You do or superintend the whole job or any part of it as the contractor
Common exceptions
- Work that doesn’t involve two unrelated trades isn’t B General Building work
- Some A applicants may qualify for an exam waiver, per CSLB
Penalties for unlicensed work
Our source doesn’t list penalty amounts. CSLB licenses and disciplines contractors, and contracting without the right license can lead to enforcement action. Check with CSLB before you bid.
