Haven ADUs

Haven ADUs specializes in designing, permitting, and constructing detached backyard accessory dwelling units exclusively for New York City homeowners, offering a full-service model that consolidates design, Department of Buildings filings, and construction management under a single point of contact. The company tailors each project to its specific lot and site conditions rather than relying on standardized plans, and handles the complete process from zoning analysis through certificate of occupancy. Haven offers four product sizes—Studio, Medium, Large, and X-Large—with units positioned to generate rental income, provide family housing, or serve as home office space in a market where backyard ADUs are now permitted.
