The Bronx is booming when it comes to affordable housing. In fact, as 6sqft recently reported, more than 43 percent of the units under Mayor de Blasio’s affordable housing plan that began construction this year were in the borough. The latest is located at 12907 Southern Boulevard in the East Tremont neighborhood, just a short walk to the Bronx Zoo. Starting tomorrow, qualified New Yorkers can apply for three $956/month one-bedrooms and three $1,080 two-bedrooms. Developed through the city’s 421-a program, the eight-story building has an elevator, laundry room, and bicycle parking.
