90 Ryerson Street represents a rare opportunity to acquire a vacant, 20-foot-wide Clinton Hill brownstone with exceptional upside for an end user seeking to create a bespoke single-family residence or a developer pursuing a boutique multifamily conversion. The property is a two-family townhouse built circa 1899, situated on a 20’ x 100’ lot (2,000 SF) with approximately 3,200 SF of existing gross floor area across three stories and 800 SF of unused FAR under R6B zoning, allowing expansion up to 4,000 SF. Delivered 100% vacant, the building allows immediate commencement of renovation and redevelopment, eliminating lease-up or tenant relocation risk. The structure retains original fireplaces, moldings, and period details that provide an ideal foundation for a high-end townhouse renovation, a feature set that consistently commands premium pricing among Clinton Hill end users. The property is located on a tree-lined Clinton Hill block within one of Brooklyn’s most supply-constrained brownstone neighborhoods, characterized by low FAR zoning and historic district restrictions that preserve long-term value and liquidity. Proximity to Pratt Institute, Fort Greene, DUMBO, and the Brooklyn Navy Yard—home to over 500 businesses and more than 2,500 employees—drives strong, durable housing demand from both end users and renters. Zoning allows for up to five residential units, compared to the existing two, offering flexibility for a multifamily investor, while the traditional 20-foot-wide rowhouse configuration and historic charm make the property especially compelling for an owner-occupant seeking a custom single-family home. Given the location, scale, and architectural character, the highest and best use is likely an end-user renovation, where emotional value, lifestyle appeal, and customization potential typically translate into the strongest pricing outcomes. Offered on an as-is basis with an asking price of $3,300,000, 90 Ryerson Street stands out as a premier Clinton Hill brownstone canvas combining vacancy, expansion potential, historic charm, and proximity-driven demand—an increasingly rare combination in today’s Brooklyn townhouse market.
