What permits do you need to open a contractor or trade in Boston?

There is no single figure, and any site quoting one is rounding away the part that matters. Of the 9 records listed for a contractor or trade in Boston, MA, 3 apply to every business of this type and 6 are conditional. Adding every fee on the page together would overstate what most operators pay, because it would include permits they never need.

Of the 3 that always apply, 1 carry a flat fee, coming to $65.00. That is a floor, not a total. 4 of the 9 are charged as a range or a formula set by the issuing agency, and 1 has no fee published at all. The ones that vary:

Certificate of Occupancy Inspection Fee: Non-residential: $110 for the first 5,000 sq ft, plus $110 per additional 10,000 sq ft, capped at $1,000. This is the Boston Fire Department's own inspection fee; ISD separately charges a distinct fee for the same certificate, reported as $300 plus a $50 application fee.

Commercial Building Permit: Long Form Building (major alteration): $50 base plus $10 per $1,000 of estimated cost. Short Form Building (minor alteration): $20 base plus $10 per $1,000. Change of Occupancy: $50. An amendment is $20 plus $10 per $1,000.

Annual Report: $110–$520 a year — $125 for a corporation on paper, $500 for an LLC

Home Improvement Contractor Registration: $250–$650 initial — a $150 fee plus a guaranty fund payment of $100 to $500 by headcount

Permits for a contractor or trade in Boston, MA come from 6 separate offices: City of Boston, Office of the City Clerk, Boston Fire Department, Fire Prevention Division, City of Boston Inspectional Services Department, Secretary of the Commonwealth of Massachusetts, Corporations Division, Massachusetts Office of Public Safety and Inspections, Division of Occupational Licensure, Massachusetts Office of Consumer Affairs and Business Regulation, Home Improvement Contractor Program. No single office issues them all, which is why an opening means filing in several places rather than one.

This is a d/b/a registration, not a general operating license — it does not itself authorize any regulated activity, which still needs its own permit (Common Victualler, Food Service, building, etc.).

Two separate fee components exist — this BFD inspection fee, and an ISD fee — but no single source states a combined total, and the ISD line item is not explicitly labelled a Certificate of Occupancy fee in the schedule that carries it, only inferred from its context alongside Change-of-Occupancy fees. Both figures are disclosed here rather than asserting one total that isn't directly documented.

Confirmed directly against the current fee schedule. Starting work without a permit, or undervaluing its cost, doubles the fee. No distinct sign-permit fee schedule exists — a new sign is filed as a Long Form Building permit under this same formula.

$500 to form, and Massachusetts is one of the few states where filing online costs more rather than less — a $20 expedite charge applies to electronic and fax filings alike. The number that matters more is the recurring one: the annual report is $500 again, every year, which is four times a corporation's and among the highest recurring entity fees anywhere. A professional LLC pays the same $500 but cannot file electronically at all. Name reservation, if you want it, is $30 for sixty days.

$275 covers up to 275,000 authorised shares and every further hundred thousand adds $100, so the fee scales with how many shares you authorise rather than issue. Filing electronically is actually cheaper here, at $265, but caps the authorisation at 275,000 shares — above that you must file on paper and pay the increment. The contrast with an LLC is stark and worth weighing before choosing a structure: a corporation's annual report is $125 against the LLC's $500. A non-profit corporation forms for just $35.

A fourfold gap between entity types, and the deadlines differ in kind as well as date: an LLC files on the anniversary of its organisation while a corporation files within two and a half months of its fiscal year end, and the Commonwealth counts arrival in its office rather than the postmark. A corporation that misses it pays $150 instead of $125. Massachusetts publishes no late fee at all for an LLC — the enforcement is administrative dissolution, after which you file a $100 reinstatement plus every outstanding report, which makes the silence more expensive than a penalty would be. A non-profit pays $15 and files by 1 November.

No fee, because Massachusetts issues no general business licence — its own five-step start-up checklist has no licence step in it. What it does have is the business certificate, and the state is careful to say what that is not: this certificate is not a business licence, it merely makes a public record of the owner's name and address. It is filed with the clerk of the city or town rather than with the state, it is needed whenever you trade under any name other than your own or your company's, and each of the three hundred and fifty-one municipalities sets its own fee, so no state figure exists. For licences, the state directs you to the licensing boards of your own city or town.

This is the credential that lets a permit be pulled, and it is not the same thing as home improvement contractor registration — the state says so in terms and warns that the two are not interchangeable. The first licence runs three years and every renewal two, which is an unusual asymmetry. Before the licence there is a $23 application and an exam at $75 for the unrestricted or restricted paper and $65 for a specialty, none of it refundable, and the licence must be claimed within a year of passing. Practising on an expired licence is prohibited outright; you may renew up to a year late without penalty, a further year for $100, and beyond two years you retake the exam. Specialty categories cover masonry, roofing, windows and siding, demolition, solid fuel appliances and insulation, each with a narrow scope — a masonry licence does not permit building a masonry building. Testing moved to the tenth edition of the building code on 1 January 2025, so older study material is obsolete.

Required of anyone who solicits, bids on or performs contracting work on an existing owner-occupied residential property of one to four units, which is most residential remodelling. The guaranty fund payment is separate from the fee and banded by staff: $100 up to three employees, $200 to ten, $300 to thirty and $500 above. Renewal is $100 every two years — but let it expire and you reapply from scratch at $150 plus the guaranty fund payment all over again, so lapsing can cost six times what renewing does. Paper applications and certified cheques are no longer accepted at all. A contractor trading under a name other than its own must supply the municipal business certificate, and an out-of-state company must complete foreign registration with the Secretary of the Commonwealth first.
