The South Boston Neighborhood Development Corp. and Braintree-based Caritas Communities Inc. have proposed a 16-unit workforce housing complex on two vacant parcels on Southie’s West Broadway, aiming to bring a measure of affordability to a stretch of road that’s seen an influx of market-rate housing and commercial space.The project team has proposed building a 13,000-square-foot, four-story building at 206-212 W. Broadway, two city-owned land parcels about a quarter-mile from the MBTA Red Line Broadway station that currently sit vacant. The project would be named 206 West and cost an estimated $4.6 million to develop.The South Boston Neighborhood Development Corp. and Braintree-based Caritas Communities Inc. have proposed a 16-unit workforce housing complex at 206-212 W.

The development team plans to ask residents to sign a “car-free pledge” and offer discounted MBTA passes to those who sign.“The site’s target demographic, central location, and proximity to the Red Line, car sharing, bike sharing and two high-frequency bus lines make a no-parking approach feasible,” the development team wrote in its filing to the BRA. “We have presented these plans to the community and have received support, despite offering no parking on the site.”The project team plans for 206 West to be “affordable to people with incomes at or below 80 percent of the area median income.” The development will have a mix of one-bedroom and studio apartments as well as 1,000-square-foot ground-floor retail space “available to a local coffee shop or similar commercial enterprise.”The 206-212 W. Broadway site is contaminated from its former use as a dry cleaner, but the city’s department of neighborhood development is remediating the contamination, the development team said.
