Iowa to Massachusetts: general contractor license reciprocity
Massachusetts has no reciprocity agreement with Iowa. Your Iowa experience counts toward eligibility, but you must pass the Massachusetts exam.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Unrestricted CSL by examination (all states; no license recognition and no NASCLA route)
Nothing is waived, but your documented out-of-state hours count toward eligibility to sit the exam.
An out-of-state general or building contractor sits the Massachusetts Unrestricted Construction Supervisor examination like any other candidate. The Board states that Massachusetts does not recognize out-of-state contractor licenses; 780 CMR 110.R5 and the candidate handbook contain no reciprocity, endorsement or examination-waiver provision, and Massachusetts is not among the jurisdictions that accept the NASCLA Accredited Examination for Commercial General Building Contractors, so a NASCLA certificate does not replace the Massachusetts examination either. Out-of-state work does count toward eligibility: the applicant must show three years, 36 months of full-time work, in building construction or design within the past ten years, proved by W-2, Schedule C or 1099 forms or by a letter of attestation from an engineer, architect, employer, military supervisor or licensed contractor, with a vocational program or bachelor's degree worth one year and a degree in architecture, engineering, science or a related technology field worth two, up to two years in total. The applicant registers with PSI, pays a $23 application fee and a $65 examination fee, and sits a 75-question open-book examination on the Massachusetts State Building Code: 180 minutes, 70% to pass, results given immediately, unlimited retakes. A passing candidate mails the score report and the $150 license fee to the Division of Occupational Licensure and receives the license card in about 30 days.
Massachusetts has no separate business-and-law examination. Massachusetts administrative responsibilities under 780 CMR are five scored questions inside the Unrestricted examination itself, which also covers plan reading and estimating, general building construction, energy efficiency, accessibility, sitework and foundations, concrete and masonry, moisture protection, structural framing in steel and wood, roofing and exterior walls, associated trades, interior environment, fire protection and OSHA safety. The examination is open book against the 2021 International Building Code, the 2021 International Residential Code, the International Energy Conservation Code, the Massachusetts amendments and stretch codes, the Architectural Access Board regulations at 521 CMR and 29 CFR Part 1926; candidates bring their own copies. A first license runs three years and renews for two-year terms at $100, with 12 hours of continuing education per cycle. One examination-free route exists and it is a Massachusetts one, not an out-of-state one: 780 CMR 110.R5.2.1 lets a person holding a current Massachusetts building official certification under 780 CMR 110.R7 apply for an Unrestricted license without testing. A CSL is not required for swimming pools, signs or tents, for projects subject to construction control, for agricultural buildings closed to the public, or for work inside a state-licensed trade such as wiring, plumbing, gas fitting, fire protection, pipefitting, HVAC or refrigeration. A contractor who also works on existing owner-occupied homes of one to four units needs the separate Home Improvement Contractor registration described on the residential level of this page.

What you must already have
- You must document at least 3 years of qualifying work experience.The experience need not be continuous and need not have been gained in Massachusetts. Education substitutes for up to two of the three years: a three- or four-year vocational school program in building construction, or a bachelor's, master's or doctoral degree, counts as one year; a degree in architecture, science, engineering or a related technology field counts as two. Union affiliation alone is not accepted, and active military service relevant to construction may be counted.
- At least 18 years old on the day of the examination, and of good moral character as determined by the Board of Building Regulations and Standards.
- Has not already passed an examination in, or held a license in, the Unrestricted class. The exception is an applicant whose license has been expired for more than two years, or who has been ordered to re-examine after a hearing.
- A notarized signature on the examination registration form confirming that the information given is true and that all Massachusetts state tax returns have been filed and state taxes paid.
What you'll do to get licensed in Massachusetts
- 1Trade exam. Pass the destination's trade exam. Massachusetts Unrestricted Construction Supervisor examination, administered by PSI: 75 questions, 180 minutes, 70% to pass (a cutscore of 53), open book, taken at a PSI center in Auburn, Charlestown, Fall River, Lawrence or West Springfield or at any PSI center elsewhere in the United States. Results are given immediately and there is no limit on retakes. PSI takes up to two weeks to review an examination application, and the approved application stays on file for two years..
- 2Application fee. Pay the application fee ($23). Non-refundable examination application fee paid to PSI when the registration form and the experience documentation are filed..
- 3Exam fee. Pay the exam fee ($65). Non-refundable examination fee paid to PSI when the examination is scheduled. An appointment can be moved without losing the fee if the notice reaches PSI two days before the test date..
- 4License fee. Pay the license or certificate fee ($150). Initial Unrestricted Construction Supervisor license fee, mailed with the passing score report to the Division of Occupational Licensure within one year of passing the examination (801 CMR 4.02(39)(a)). The first license runs three years; renewals are $100 for a two-year term, and a renewal filed more than one year but less than two years after expiry carries a $100 late fee. A license more than two years past expiry cannot be renewed and the examination must be taken again..
- 5Other. Documentation of the three years of experience filed with the examination application: W-2, IRS Schedule C or 1099 forms covering the equivalent of three years of full-time work, or, instead of tax records, a letter of attestation from an engineer, architect, employer, military supervisor or licensed contractor. Where education is used for part of the experience, a copy of the diploma or degree is filed as well..
- 6Continuing education. Complete continuing education. Renewal condition rather than an entry requirement: an Unrestricted construction supervisor completes 12 hours of Board-approved continuing education in each two-year renewal cycle, made up of four hours of code review and at least one hour each of workplace safety, business practices and workers' compensation, energy and, in the first renewal cycle only, lead safe practices, with the balance as approved electives. No more than six of the hours may be taken online; the rest must be classroom based. Courses should be finished at least 60 days before the license expires, and a certificate used for one renewal cannot be used again. A Specialty license carries six hours per cycle on the same pattern..
- 7Background check. Complete a background check. There is no fingerprint or criminal record check for the Construction Supervisor License itself, but under 780 CMR 110.R5.2.9.2 the Board may require an applicant or licensee to disclose any conviction, felony or misdemeanour, or any civil finding made against them by a court, by another state or federal agency, or by a licensing board in another jurisdiction, either at application or at the next renewal..
- 8Insurance. Carry the required insurance (if applicable). The Construction Supervisor License carries no surety bond, financial statement, net worth, working capital or general liability insurance requirement; 780 CMR 110.R5 sets none and the fee schedule collects only the application, examination and license fees. Workers' compensation obligations apply to the business independently of the license, and owners, lenders and general contractors commonly require liability coverage by contract..
- 9Other. On-site obligations that come with the license: the license holder must carry the license card at all times during construction work on any site and produce it if a building official asks; every building permit application must carry the supervisor's name, signature, license number and license category; and if that supervisor stops supervising the work, the work must stop until a successor license holder is substituted on the building department's records. The license holder is fully responsible for all work supervised, even when they are a subcontractor rather than the permit holder, and must notify the building official in writing of any violation discovered under the permit..
Published fees on this path total $238, excluding exam-vendor fees, bonds, and insurance.

How Massachusetts licenses general contractors
Massachusetts general contractor · “Construction Supervisor License, Unrestricted”
Statewide license
The broadest contractor credential Massachusetts issues is the Unrestricted Construction Supervisor License (CSL), and it is not split residential against commercial the way most states split their general and residential tiers. The Unrestricted CSL covers construction, reconstruction, alteration, repair, removal and demolition of buildings of any use containing less than 35,000 cubic feet of enclosed space, together with one- and two-family dwellings of any size, agricultural buildings and retaining walls under ten feet, so it is the commercial and mixed-use tier as well as the homes tier. Above 35,000 cubic feet there is no contractor license to hold: the Board states that a registered design professional, an engineer or architect, controls the construction of larger buildings and 'a construction supervisor license is not required for larger projects since the RDP is considered the licensed person for the project'. There are also six Specialty CSL classes - masonry, roof covering, windows and siding, solid fuel-burning appliances, demolition and insulation - each carrying the same building-size scope within its own trade. Like the homes-only class, the Unrestricted CSL is held by a person rather than by a business: M.G.L. c. 143, § 94(i) has the Board issue licenses 'to individuals engaged as construction supervisors', so a contractor moving to Massachusetts applies in their own name rather than qualifying a company, and every building permit application names that individual and their license number. Massachusetts publishes no dollar limits and no classification tiers beyond these, and the Board states that 'Massachusetts does not recognize out of state contractor licenses'.
