The Boston Zoning Commission has approved the Planned Development Area development plan (PDA) that will provide the zoning regulations for the Parcel 24 project, a 325-unit, mixed-income housing development in Chinatown.

The PDA for Parcel 24 provides a comprehensive set of zoning regulations for the project, beyond what would be possible under conventional zoning.

Parcel 24 will restore housing and commercial space to a site on Hudson Street that was demolished more than 40 years ago, when homes and businesses on the east side of the street were cleared to make way for a turnpike ramp. The completion of the Big Dig allows this block, bordered by Hudson, Kneeland and Albany streets, to be reknit into the urban fabric and provide sustainable, transit-oriented housing, according to the Zoning Commission.

“Today’s Zoning Commission approval is a win for the Chinatown neighborhood as well as the city of Boston because Parcel 24 will double the number of owner-occupied homes in Chinatown,” said Jeremy Liu, the executive director of the Asian Community Development Corp.
