A summary of multi-family housing developments in the works in Wellesley, Mass. Some may be very much on the drawing board…
The planned sale of numerous office properties in town could pave the way for new residential or mixed-use developments.
Wellesley in 2024 complied with the state’s MBTA Communities Act, designed to encourage more residential development near public transportation.
A Strategic Housing Plan is in the works in 2025 to guide Wellesley’s efforts to support development of a range of housing types.
As of 2023 (latest state figures available), 10.68% of Wellesley’s housing stock was deemed affordable. Communities below the state’s 10% threshold are subject to unsolicited 40B projects that give developers great leeway from zoning rules.
Jump to development:
- 136-140 Worcester St.—15 units
- 16 Laurel Ave. (The Laurel)—28 units
- MassBay property (40 Oakland St.)—180 units
- 49 Walnut St.—28 units
- Wellesley Park (40R district)—no plans yet, but zoned for 850 (350 have been built)
- The Bellwether (192-194 Worcester St.)—34 units
- 592 Washington St.—19 units
