Construction in Massachusetts means working under 780 CMR, the Massachusetts State Building Code, plus the Specialized Stretch Code in 14 leading municipalities (Boston, Cambridge, Newton, Brookline, Somerville, and others). It also means navigating the HIC consumer protection law and the new 2024 ADU Law that legalized accessory dwelling units by-right in most MA municipalities. Most general contractors subcontract trades. We hold the Massachusetts Licensed Construction Supervisor License plus electrical, plumbing, gas-fitter, HVAC, and EPA RRP credentials in-house — your project doesn't bounce between contractors, and your warranty doesn't disappear when one of them goes out of business.
Why Massachusetts Construction Is Different
- Pre-1978 housing dominates. Most Boston, Cambridge, Somerville, and Brookline housing predates 1978. Federal EPA RRP lead-safe handling is required for any work disturbing painted surfaces — a separate certification most general contractors don't hold.
- Specialized Stretch Code. 14 MA municipalities require all-electric heating in new construction and major renovations. Kitchen or whole-home remodels in these cities trigger HVAC + electrical scope changes generic contractors miss.
- 2024 ADU Law unlocked the market. Massachusetts now allows accessory dwelling units by-right (without special variance) in most municipalities. Garage conversions, in-law suites, and detached ADUs are the fastest-growing construction segment in MA.
- Boston triple-decker is its own scope. Boston's distinctive triple-decker (~3-unit detached frame house) requires multi-unit code knowledge, knob-and-tube replacement, full mechanical separation, and historic-district overlays in many neighborhoods.

- Kitchen + panel upgrade + gas line + ductwork. A standard MA kitchen remodel triggers all four. We coordinate as one project — single permit, single timeline.
- ADU + 200-amp panel upgrade + heat pump install. ADUs in Specialized Stretch Code municipalities require all-electric. We handle electrical service drop, panel, and heat pump on one permit set.
- Whole-home renovation + Mass Save insulation + air sealing. Studs-out renovation is the perfect window for Mass Save insulation rebates. Stack rebates with HVAC electrification.
- Basement finishing + sump pump + waterproofing. Wet basement = wet finished basement. Waterproof first, finish second.
