Massachusetts Construction Supervisor License Renewal

Last reviewed October 2026 · 5 min read

A Massachusetts Construction Supervisor License (CSL) from the Massachusetts Board of Building Regulations and Standards (BBRS) runs three years when first issued, then two years with each renewal. Renewing costs $100 and takes continuing education first: 12 hours for an unrestricted license, 10 for a restricted (one- and two-family) license and 6 for a specialty license, with no more than 6 hours online. You can't work as a construction supervisor on an expired license, but there's a one-year grace period to renew, and for an additional $100 it can be renewed up to two years after expiration.

At a glance

Renews every: Two years. A license expires three years from the date it's first issued, and each renewal license expires two years from its date of issuance, which is noted on the license
Who needs one: The board says a licensed construction supervisor or a registered design professional must oversee construction of 1- and 2-family homes and most existing 1- to 4-family owner-occupied homes, and of buildings under 35,000 cubic feet of enclosed space. The building code has a homeowner exemption, and the local building official may have other licensing requirements
Continuing education: 12 hours for an unrestricted license (CS), 10 hours for a restricted one- and two-family license (CSFA) and 6 hours for a specialty license (CSSL), however many specialties it covers, every two-year license cycle. Complete it before you request a renewal application
Required topics: Code review (4 hours for a CS or CSFA license, 2 hours for a CSSL), plus 1 hour each of workplace safety, business practices/workers' compensation and energy (except a demolition specialty license). Lead safe practices (1 hour) is required for the first renewal cycle only. Approved electives make up the rest
Online limit: Up to 6 hours may be taken online; the remaining hours must be in-person classroom training. A specialty license's 6 hours can all be online. Course certificates submitted for an earlier renewal can't be submitted again
When to finish CE: The board says to complete your courses at least 60 days before your license expires
Renewal notice: License renewal notifications are sent 60 days before license expiration
Fee: $100 to renew
How to renew: Online through the board's renewal portal. By mail, email OPSI-info@mass.gov to request a renewal application, then mail it with your continuing education certificates and a check or money order payable to the Commonwealth of Massachusetts to P.O. Box 414376, Boston, MA 02241-4376. Or renew in person at the Division of Occupational Licensure, One Federal Street, Suite 600, Boston
Processing: Allow 5 weeks for the application to be processed
Expired license: Working as a construction supervisor on an expired license is prohibited
Late renewal: There's a one-year grace period to renew after expiration. For an additional $100 fee, a license can be renewed up to two years after expiration. The board says that expired for more than two years, you take the exam and apply for a new license; the regulation has exceptions for medical or military reactivation and for active military duty
On the job: Keep the license with you at every building site while you're doing construction work: a building official may ask to see it at any time on a job site

A CSL and an HIC registration are separate, and one can't stand in for the other: the board says a contractor working on most existing 1- to 4-family owner-occupied homes must also register with the home improvement program. See the Massachusetts HIC registration guide for that renewal.

Massachusetts does not recognize out-of-state contractor licenses.

Building officials who are certified and in good standing are exempt from the continuing education requirement.

How to renew

Finish your continuing education (12, 10 or 6 hours by license type, no more than 6 online) at least 60 days before the license expires, and keep the course certificates.
Renew online, or email OPSI-info@mass.gov for a renewal application and mail it with your course certificates and a $100 check or money order payable to the Commonwealth of Massachusetts.
Allow 5 weeks for processing, then keep the renewed license with you on every job site.

The license isn't the only thing expiring

Most lapses that cost contractors work aren't the license itself. They're one of these, renewing on a different date:

Your Home Improvement Contractor (HIC) registration, a separate registration on its own two-year date, if you hold one
Any local license your city or town asks for
General liability insurance policy
Workers' compensation policy (or exemption)
Certificates of insurance (COIs) you've given to clients and GCs
Commercial auto insurance

LicenseLedger keeps every one of those dates in one place and emails you before each one expires, with reminders far enough ahead to finish CE and paperwork.
