Mayor Martin J. Walsh announced Wednesday that more than $26 million of new funding will go toward 515 housing units throughout Boston.

“As Boston continues to grow, we want to make sure everyone has a place to call home, no matter their income,” Walsh said in a press release. “It’s important now more than ever that we use every tool in our toolbox to build more housing for working families in our City. This announcement is a great example of how we’re building strong partnerships in the housing community to create more affordable housing options across all of our neighborhoods.”

The funding comes from the Department of Neighborhood Development, the Neighborhood Housing Trust and the Community Preservation Fund. It will create 459 new units and preserve 56 units of housing already in place. The funding will also create and preserve 290 income-restricted units for households with low, moderate and middle incomes. The housing units will stretch across Brighton, East Boston, Dorchester, Mattapan, Mission Hill, North End and Roxbury.

“DND is excited that we were able to fund projects with such deep affordability, ranging from 50 percent of the Area Median Income to homeless individuals and the elderly,” Sheila Dillon, the city’s chief of housing said in a press release. “I can’t wait to see these projects completed, and I want to thank the Neighborhood Housing Trust, the Community Preservation Committee, and our partners in the housing community for helping us create more affordable housing in Boston.”

The announcement came at the Knights of Columbus in the North End, where a 23-unit affordable housing apartment will house homeless seniors.

“This is an exciting day,” Walsh said. “We came up with an ambitious plan of new units of housing by the year 2030. It’s one unit at a time.”
