The license requires 4 years of journeyman-level experience or equivalent education, passing the Law & Business exam and C-8 trade exam.

Permit fees range from $50-300 depending on project scope and valuation. Commercial projects may require additional plan review and take 20-30 days.

Insurance Requirements
