The Boston Housing Authority (BHA) has selected nonprofit affordable housing agency Inquilinos Boricuas en Acción (IBA) to redevelop 146 public housing units on West Newton and Rutland streets in Boston’s South End.

IBA was one of three agencies that submitted proposals for the project to the BHA. The project will preserve affordability for low-income households and prevent displacement of existing residents, IBA CEO Vanessa Calderon-Rosado said in a statement.

“In light of the competition from larger for-profit developers, we are appreciative that the BHA recognized our investment in the South End to build community for our residents. We look forward to furthering our mission with this project,” Calderon-Rosado said.

IBA was founded in 1968 by a group of Puerto Rican activists opposed to urban renewal projects in the South End. It owns and manages the 435-unit Villa Victoria affordable housing community in the South End and sponsors youth development, workforce programs and arts programming.

IBA plans to rehabilitate the 24 historic townhouses by updating utilities, repointing exteriors, renovating interiors and installing solar panels, Calderon-Rosado told Banker & Tradesman last month. In conjunction with the BHA, it will schedule a series of community meetings and design charettes before beginning the project.
