Introduction: Construction Contractor Licensing in Massachusetts
For one and two-family houses, any size: A person with a MA construction supervisor license (CSL) is required to provide construction oversight, with few exceptions. For most work on existing one-to-four family owner-occupied dwellings, a contractor must also register with the Office of Consumer Affairs home improvement program.
For buildings less than 35,000 cu ft: A person with a MA construction supervisor license (CSL) is required to provide construction oversight including for manufactured buildings.
For buildings greater than 35,000 cu ft: Construction of such larger buildings and structures, commercial and residential, must be done under the control of a registered engineer or architect or their designee and no contractor license is necessary per the building code. See Section 107.6 entitled “Construction Control” in the MA building code. A few municipalities may have other contractor licensing requirements.
Out of state contractors: Licensing is only required as described above. Out of state licenses are not recognized in MA. A few larger municipalities have additional licensing requirements. The building code applies uniformly to all municipalities in MA and is enforced by the local officials with few exceptions.
Renewing a Construction Supervisor License
- Complete the required continuing education credits. See: Continuing Education
Request a renewal application from DPS by email. See: Request for CSL Renewal Form (Check your spam or junk folders for a "Renewal Notice Enclosed" item from "EOPSS MA", after you send this request. Allow up to three days to receive this form.)
- Complete and mail in the renewal application. Attach payment and CEU certificates. Allow up to five weeks for processing.
Licenses must be renewed every two years for a fee of $100.00. There is a one year grace period to renew licenses after expiration. For an additional fee of $100.00, licenses can be renewed up to two years after expiration. Beyond that it’s necessary to take an exam and apply for a new license.

DOCUMENTATION OF WORK EXPERIENCE
Provide either tax forms or a letter of attestation, but not both, as follows:
- Tax forms. W-2, or IRS Schedule C or 1099 forms are acceptable. Submit forms for the equivalent of three years full time experience. If education is used for experience then submit a copy of the diploma and/or degree that you acquired.
- Letter of Attestation. In lieu of tax records a notarized letter of attestation from an individual (e.g. engineer, architect, employer, military supervisor, licensed contractor, or other) stating that you have at least three years of construction and/or design experience.
