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 Credential | Experience Credit |
|---|---|
| Completed 3- or 4-year vocational high-school program in building construction | Counts toward part of the 3-year requirement (roughly 1-2 years) |
| Bachelor's degree from an accredited college or university | Counts 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:
- Apply to sit for the exam. Submit your eligibility documentation (age, experience, and education credit if applicable) to establish that you qualify to test.
- 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.
- Apply to BBRS for the license. After passing, submit your license application to BBRS, including the notarized tax attestation.
- Pay the initial license fee. $150 for the base license; add $100 per additional Specialty category if you're licensing more than one specialty.
- 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 Category | CE Hours per Renewal Cycle |
|---|---|
| Unrestricted CSL | 12 hours |
| One- and Two-Family Dwellings CSL | 10 hours |
| Specialty CSL | 6 hours |
Within those hours, specific topics are mandatory:
| Required Topic | Hours |
|---|---|
| Code Review | 4 |
| Workplace Safety | 1 |
| Business Practices / Workers' Compensation | 1 |
| 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.
