What's actually being remodeled in Dorchester
Dorchester is Boston's largest neighborhood, Savin Hill, Ashmont, Lower Mills, Codman Square, and Fields Corner each have a different housing mix. Most stock is triple-deckers and two- and three-families from 1890–1925 with original plaster, cast-iron drains, and second-floor bathrooms. Newer Ashmont and Lower Mills infill scopes more cleanly.
- Triple-decker and two-family bathroom updates with plaster and cast-iron drains
- Owner-occupied multifamily owners converting tubs to walk-in showers
- Pre-sale full bathroom remodels in Ashmont and Savin Hill
Greater Boston housing stock and conditions
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.
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.
- 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

How Dorchester 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.
