1.4 Eligibility, Experience Credit & the Application Process

Key Takeaways

  • Eligibility requires being 18 or older and documenting 3 years of full-time (40 hours/week) building construction or design experience within the past 10 years.
  • A completed vocational high-school building construction program or a bachelor's degree can each offset part (roughly 1-2 years) of the experience requirement, not all of it.
  • Applications require a notarized attestation of current Massachusetts state tax compliance.
  • Licensing runs in a fixed order: apply to sit, pass the PSI exam, apply to BBRS for the license, pay $150 (plus $100 per additional specialty), license issued.
  • Renewal is every 2 years for $100, with continuing-education requirements of 12 hours (Unrestricted), 10 hours (One- and Two-Family Dwellings), or 6 hours (Specialty), including mandatory Code Review, Safety, Business Practices, Energy, and first-cycle-only Lead Safe Practices topics.

Who Can Sit for the Exam: Age and Experience

To be eligible to sit for the CSL exam, a candidate must be at least 18 years old and must document 3 years of full-time (40 hours per week) building construction or design experience within the past 10 years. "Full-time" and "40 hours per week" are the operative words — BBRS is looking for sustained, substantial hands-on or design experience in the field, not scattered part-time work spread thin over a decade.

How Education Can Offset Experience

BBRS recognizes that formal education develops relevant competence too, so two education paths can count toward part of the 3-year requirement:

Education CredentialExperience Credit
Completed 3- or 4-year vocational high-school program in building constructionCounts toward part of the 3-year requirement (roughly 1-2 years)
Bachelor's degree from an accredited college or universityCounts toward part of the 3-year requirement (roughly 1-2 years)

Key Point: Neither credential eliminates the experience requirement entirely — each can only offset part of the 3 years, generally in the range of 1 to 2 years. Candidates still need documented hands-on or design experience to fill the remainder. Don't assume a bachelor's degree alone satisfies eligibility on its own; confirm your specific combination of education and experience against current BBRS application instructions before applying.

The Tax Compliance Attestation

A detail candidates frequently overlook: as part of the application, you must attest — via a notarized statement — that you are current on your Massachusetts state tax obligations. This is a compliance gate, not a technical requirement, but a missing or improperly executed attestation can hold up an otherwise-qualified application. Get it notarized correctly the first time so it doesn't become the reason your paperwork stalls.

The Application Process, Start to Finish

The path from "I want a CSL" to "I have a CSL" runs through two different organizations in a specific order:

  1. Apply to sit for the exam. Submit your eligibility documentation (age, experience, and education credit if applicable) to establish that you qualify to test.
  2. Pass the PSI exam. Schedule and sit for the Unrestricted (75 questions, 4 hours/240 minutes), Restricted (One- and Two-Family, 60 questions, 4 hours/240 minutes), or Specialty (30-50 questions, 120-180 minutes) exam — open book, 70% passing score. Pay the $75 exam fee to PSI for the Unrestricted or Restricted exam (or $65 for a Specialty exam), plus the $23 application fee.
  3. Apply to BBRS for the license. After passing, submit your license application to BBRS, including the notarized tax attestation.
  4. Pay the initial license fee. $150 for the base license; add $100 per additional Specialty category if you're licensing more than one specialty.
  5. License issued. Once BBRS processes the application and fee, your CSL is issued and active.

Keeping the License: Renewal and Continuing Education

A CSL is not a one-time credential — it must be renewed every 2 years for a $100 fee. Renewal requires completing continuing education (CE) through BBRS-approved providers in the 2 years before expiration. The number of required CE hours depends on your license category:

CSL CategoryCE Hours per Renewal Cycle
Unrestricted CSL12 hours
One- and Two-Family Dwellings CSL10 hours
Specialty CSL6 hours

Within those hours, specific topics are mandatory:

Required TopicHours
Code Review4
Workplace Safety1
Business Practices / Workers' Compensation1
Energy (except Demolition specialty)1
Lead Safe Practices (first renewal cycle only)1

Any remaining hours needed to reach the 12/10/6-hour total for your category can be filled with elective coursework.

If You Miss a Renewal

Life happens. Massachusetts allows a grace period of up to 2 years to renew a lapsed license, but it costs an additional $100 on top of the standard $100 renewal fee. Letting a license lapse past that grace window means starting the licensing process over rather than simply renewing — so treat the grace period as a safety net, not a scheduling strategy.

On the Exam

This chapter's material (eligibility, categories, and the CSL/HIC distinction) is background BBRS expects licensed supervisors to understand about their own regulatory system. It tends to show up less as code-lookup questions and more as administrative/procedural questions within the Administrative Responsibilities domain. Know the sequence — apply to sit, pass exam, apply for license, pay fee, license issued — and the renewal numbers (2 years, $100, CE hours by category) cold.
