The qualifying individual, what counts as "credible"

Your qualifying individual (the person signing your work experience) should be someone who supervised you, worked alongside you, or contracted with you in a position to observe your work. Most commonly: a previous employer, a CSLB-licensed contractor you worked under, or a journeyman in your trade. The CSLB does not require a specific relationship, credibility is what matters.

The CSLB occasionally audits work-experience certifications. If they request additional proof, you may need to provide W-2s, 1099s, project addresses, or signed statements from clients. Build a paper trail as you go, don't try to reconstruct it years later.

Education substitution

Up to 3 of the 4 required years can be substituted with education:

• Associate's degree in construction-related field: 1.5 years credit
• Bachelor's degree in construction-related field: up to 3 years credit
• Apprenticeship completion: up to 3 years credit
• Construction-related vocational training: case-by-case, typically 6-12 months credit

At least 1 year of actual on-the-job experience is always required.

Bonds, insurance, and fees

• $25,000 contractor bond, required for every active license. Typical premium: $200-$400/year depending on credit.
• $25,000 qualifying individual bond, required if licensed via RME instead of RMO.
• Workers' Compensation insurance, required for any licensee with employees. Always required for C-39 roofing contractors regardless of employee count.
• $200 initial license fee, paid after passing both exams.
• $450 biennial renewal, every 2 years.
