An application for a Special Permit pursuant to ZR Section 74-711 was approved by the City Council on October 9, 2025. The permit facilitates the conversion of an existing 5-story manufacturing building into a 104-unit residential building at 345 Carroll Street, Brooklyn. The proposed project includes 30% affordable housing units. The building will largely maintain its existing envelope and facade, preserving its historic industrial character. The site is currently zoned M1-1, and the special permit allows for residential use in this manufacturing district, which would otherwise be prohibited. Modifications approved by the City Council focused on increasing the number of affordable units and ensuring local hiring preferences for construction jobs. The total development area is approximately 110,000 square feet.
