Massachusetts Contractor License Requirements: 2026 Comprehensive Guide
Massachusetts operates a dual-credential system for residential contractors. The Home Improvement Contractor (HIC) registration covers the business entity. The Construction Supervisor License (CSL), issued by the Board of Building Regulations and Standards (BBRS), covers the individual supervising construction. Both are required for most residential construction and remodeling work, they are not interchangeable. The CSL exam switched to the 10th Edition Massachusetts State Building Code on January 1, 2025. HIC program regulations were updated June 6, 2025. This guide covers every Massachusetts requirement in effect for 2026.
The Dual System - HIC and CSL
The HIC registration (OCABR) covers the contractor business entity's consumer protection obligations. The CSL (BBRS) covers the individual's authority to directly supervise construction, alteration, repair, or removal of any building or structure. If you own the company and personally supervise work, you need both. If you employ a separately licensed supervisor, the company needs an HIC and the supervisor needs a CSL. The HIC alone does not authorize supervision. The CSL alone does not cover the business entity's obligations.
HIC Registration Requirements
No exam, no experience verification. GL insurance proof required (verify current minimum at mass.gov/ocabr). Guaranty Fund participation: $25,000 maximum payout per claim. No surety bond required.
Fees: $150 new, $100 biennial renewal. The 201 CMR was updated June 6, 2025 - verify current requirements at mass.gov/ocabr before applying.
CSL Requirements - 10th Edition Exam
Three years of verifiable construction experience or equivalent education required. CSL exam administered by PSI - switched to 10th Edition Massachusetts State Building Code (780 CMR) effective January 1, 2025. Any contractor who studied for the 9th Edition exam and has not yet tested is using outdated material.
Fees: $150 initial, $150 biennial renewal. CE requirement: 12 hours per renewal cycle (6 mandatory, 6 electives).
Specialty CSL designations include Unrestricted, 1-2 Family Residential, Manufactured Homes, Demolition, and Masonry. Unlicensed Penalty HIC: civil penalty up to $1,000 per day. CSL: criminal penalties including fines and stop-work orders.
For insurance guidance see our Massachusetts contractor insurance requirements guide.
Pro tip: Massachusetts’s HIC and CSL have different biennial renewal dates tied to issuance dates, not a universal expiration calendar. Track both renewal dates independently. A lapsed CSL means you cannot legally supervise any construction even if your HIC registration is current, a common and costly oversight for busy contractors.
Bottom Line and Next Steps
The January 2025 CSL exam edition change is the most important current item for exam candidates. The June 2025 HIC regulation update may have changed disclosure or insurance requirements - verify at mass.gov/ocabr. Track HIC and CSL renewal dates independently, they can fall in different years.
