General Licensing Questions

Who needs a Massachusetts Construction Supervisor License?

A general contractor in Massachusetts is known as a Construction Supervisor. Construction of all one and two family dwellings and all buildings containing less than 35,000 cubic feet of enclosed space must be constructed under the supervision of a person licensed as a Construction Supervisor by the State Board of Building Regulations and Standards.

Do I need an Unrestricted or a Restricted license?

Unrestricted — You must be licensed as an Unrestricted Construction Supervisor if you are directly supervising persons engaged in construction, reconstruction, alteration, repair, removal or demolition involving any activity regulated by the code for:

  • Buildings containing less than 35,000 cubic feet of enclosed space: and
  • One- and two-family dwellings or any accessory building regardless of size

NOTE: Buildings over 35,000 cubic feet require the control of an engineer or architect.

Restricted — (One- and Two-Family Dwellings Only). This license limits you to direct supervision of persons engaged in construction, reconstruction, alteration, repair, removal or demolition involving any activity regulated by the code for:

  • Any one-and two-family dwellings regardless of size, or
  • Any accessory building regardless of size.

Please note that many municipalities in Massachusetts, separate from the State requirements just noted, often require some type of contractor’s licensing on larger buildings. Please check with local municipalities directly for local contractor licensing requirements in addition to the State requirements.

Are there any exemptions from the Construction Supervisor License requirement?

The State Building Code provides exemptions for the following construction related activities:

  • Construction of swimming pools
  • Erection of signs
  • Erection of tents
  • Any building which is subject to construction control

Some local municipalities still require the above types of contractors to be licensed. Please check with your local building department for verification.

What work experience do I need in order to obtain a CSL?

Your work experience does not have to be continuous, but over the past 10 years you most have a total of 36 months or full-time (40 hours per week).


  • Successful completion of a three-or four-year vocational high school or other vocational school program in the field of building construction or completion of a bachelor, master or PhD degree from an accredited college or university shall be deemed as satisfying one year of work experience.
  • Successful completion of a bachelor, master or PhD degree from an accredited college or university in architecture or science, engineering, or technology in a related field shall be deemed as satisfying two years work experience.
  • Education can account for a maximum of two years experience.

Please note:

  • Union affiliation only is not acceptable as work experience.
  • Active military service relevant to construction may be considered as work experience

How do I verify my construction or design experience?

Work experience may be verified in one of two ways:

  1. 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.
  2. Letter of Attestation: In lieu of tax records a 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.

About the Courses

Once I order the course, how long before I can start?

You may begin immediately! Simply click the Login button in the upper right-hand corner on your desktop or in the upper-right menu on mobile. Once you’ve entered your login and password, you will be taken to your courses. Follow the instructions and enjoy!

Once I start an online course, will I be able to start and stop at anytime?

Our courses are available online 24/7 and you are able to log in and log out at any time during the course. If you are going to be away from your computer for more than 10-15 minutes, simply log out. When you log back in, you will be able to re-enter the lesson you were last in.

How long do your continuing education courses take to complete?

Continuing education requirements vary by state. Each course lists a minimum number of credit hours required to complete the course.

How long do your exam prep courses take to complete?

Each course lists the total amount of hours for the course. However, we cover materials quickly and many contractors like to re-watch materials. In other words, this question really depends on your learning style. We recommend that you go through the course as many times as you need to be comfortable with the material and any applicable reference books. The more familiar you are with the materials, the better you will do on your exam!

How long do I have the courses?

We allow up to 6 months for you to complete the courses. During the six months you have unlimited, 24/7 access. If you need additional time, please contact our offices to arrange an extension (please note: a fee may apply).

Are there tests in the courses?

This varies depending on whether the course is continuing education or exam prep.

There are no quizzes for continuing education courses in Michigan. All other states with continuing education require quizzes to check completion progress.

In exam prep courses there will be a short quiz at the end of each lesson and there is also a longer practice test at the end of each course. These quizzes and tests will help you practice taking an exam and identify areas you may wish to study more.

If I fail a practice test, do I have to take it again?

Practice tests are just that: for practice. You will have the opportunity to retake the practice tests until you do pass. The practice tests are there to help you get used to the process of using your reference materials and finding the correct answers during an exam. If you don’t pass on the first try, take the time to note what sections of the material you need to review.

Once I complete a course, can I still go back and review the lessons and quizzes?

You are able to review the lessons and quizzes at any time during the six months you’ll have access to the courses.
