The housing stock driving Greater Boston remodels
Eastern Massachusetts has the oldest housing stock in the sample: large volumes of pre-1940 triple-deckers, colonials, and capes across Middlesex, Essex, Norfolk, and Suffolk counties.
- Plaster and knob-and-tube discoveries make contingency budgets of 15-20 percent standard, not optional
- Full gut remodels outnumber partial refreshes because partial work exposes non-code conditions
- Municipal inspection scheduling, not materials, is the top cause of local schedule slip
Local conditions that change the spec here
Old framing, knob-and-tube remnants, plaster walls, and undersized supply lines mean Boston-area remodels almost always involve trade work beyond the bathroom itself.

How Greater Boston compares with the national picture
The national direction is consistent everywhere: showers replace tubs in secondary baths, curbless entries move from specialty to standard, and ventilation gets specified deliberately instead of by default. What changes locally is how much of that work is triggered by failure versus choice, and how much the same scope costs.
