Massachusetts Contractor License & Insurance Requirements

Massachusetts requires a Construction Supervisor License (CSL) for anyone supervising construction, alteration, or demolition of buildings under the State Building Code. Separately, contractors doing $500+ of residential remodeling must hold a Home Improvement Contractor (HIC) registration with the Office of Consumer Affairs.

License threshold
CSL: any supervisory construction work. HIC: $500+ of residential remodel/repair work.
WC trigger
All employers (M.G.L. c. 152 §1)
Bond
HIC: $200 application fee + Guaranty Fund participation (consumer pool). CSL: no bond.
License authority: MA Board of Building Regulations and Standards (BBRS) — CSL; Office of Consumer Affairs — HIC license verification portal.

Workers' comp posture

Massachusetts General Laws Chapter 152 requires WC for ALL employers from the first employee. Construction-industry sole-proprietors and corporate officers may exclude themselves but must file with DIA. Independent-contractor classification is governed by the strict M.G.L. c. 149 §148B 'ABC test'.

Common public-bid insurance minimums

These are limits commonly required on MA public-works prequalification. They are NOT a state-mandated minimum — verify against your specific procurement spec or contract.

General Liability
$1M per occurrence / $2M aggregate (typical MassDOT + DCAMM spec)
Workers' Comp
Statutory + $1M Employer's Liability
Auto Liability
$1M combined single limit

Massachusetts state-specific quirks

3 pitfalls every MA GC misses

ABC-test misclassification

M.G.L. c. 149 §148B treats failure of any of the three prongs as employee status — and triggers WC + wage-and-hour liability. A 1099 acknowledgment is not protective.

CSL class mismatch

A 'CSL Restricted 1A' sub cannot supervise outside their class. Pull the actual CSL class + restrictions from the BBRS lookup.

Forgetting HIC for residential remodel

A licensed CSL doing residential remodel ALSO needs HIC registration with the OCA — different system, different renewal. Capture both.

Frequently asked questions

What's the difference between CSL and HIC in Massachusetts?

CSL is a Construction Supervisor License from BBRS — required for anyone supervising state-building-code construction. HIC is a Home Improvement Contractor registration from OCA — required for residential remodel/repair over $500. Many subs need both.

What's the Massachusetts ABC test?

M.G.L. c. 149 §148B requires (A) the worker is free from control, (B) performs services outside the employer's usual course of business, AND (C) is independently established in that trade. Failure of any prong = employee, not contractor.

Does Massachusetts require workers' comp from the first employee?

Yes. M.G.L. c. 152 applies WC to ALL employers from first hire. Construction sole-prop and corporate-officer exclusions exist but must be filed with DIA.

How do I verify a Massachusetts contractor license?

Use the MA eLicensing portal at elicensing21.mass.gov/CitizenAccess for both CSL and HIC. Confirm class, status, restrictions, and any disciplinary history.

What is the MA Guaranty Fund?

A consumer-protection pool funded by HIC fees that pays homeowners up to $10,000 per claim for unfinished or defective residential work by HIC-registered contractors.
