Frequently asked questions
When do I need a California contractor license?
Any project with combined labor and materials of $1,000 or more requires a CSLB license. The threshold rose from $500 to $1,000 on January 1, 2025.
How much experience do I need to qualify?
Four years of journey-level or higher experience within the past 10 years. Education or apprenticeship can offset up to 3 years, leaving a 1-year hands-on minimum.
What bond do I need?
A $25,000 contractor license bond is required. LLCs must also post an additional $100,000 employee/worker bond.
Does California have reciprocity with other states?
Yes. CSLB has agreements with Arizona, Nevada, and Utah that can waive the trade exam for qualifying applicants, though the Law & Business exam is still required.
How long does the whole process take?
Typically 6-9 months when accounting for application processing, exam scheduling and preparation, and final license issuance.
