The Basement Apartment Conversion Pilot Program (BACPP) provides eligible homeowners of 1-3-family buildings in Brooklyn’s Community District 5 neighborhoods of East New York and Cypress Hills with low- or no-interest loans, and possibly forgivable, to convert their basement or cellar into a safe, legal apartment for rental occupancy.

The program’s goal is to create additional legal, safe housing in these neighborhoods. Eligible homeowners can apply for a low or no-interest loan to finance the renovation.

This is a limited, pilot program, and homeowners were encouraged to express interest by May 31, 2019. Although you can still express interest, there is no guarantee you will be able to participate in the program.

Information and assistance is available in English and Spanish.

Learn more about the pilot program.
