Troy Zoning & Land Use Guide
Key Zoning Facts
Troy Zoning Overview
Troy is located on the east bank of the Hudson River across from Albany in Rensselaer County. The city is home to Rensselaer Polytechnic Institute (RPI), one of the nation's oldest engineering universities, and Russell Sage College. Troy has experienced a notable resurgence in recent years, with its downtown and waterfront areas attracting restaurants, shops, artists, and young professionals. The city's Troy Waterfront Farmers Market has become one of the most popular in the Capital Region, anchoring a broader revitalization of the downtown commercial district.
Troy's exceptional stock of 19th-century architecture, including intact blocks of Italianate and Second Empire rowhouses, provides both a preservation challenge and a development asset. The city's planning framework addresses adaptive reuse of historic buildings, downtown vitality, student housing management around RPI, and waterfront development along the Hudson River. Troy's Comprehensive Plan Realize Troy supports investment in the city's urban core while preserving neighborhood character.
Key Zoning Districts
Troy's zoning includes residential zones (R-1, R-2, R-3), commercial zones (C-1, C-2, C-3), industrial zones, and waterfront districts. The downtown core has commercial zoning supporting mixed-use development. The Hillside neighborhood around RPI has residential zoning with student housing considerations. The riverfront areas have been designated for mixed-use redevelopment.
ADU Regulations
Troy permits accessory dwelling units in residential zones with size limits of 750 square feet and owner-occupancy of one unit. No additional parking is required. ADUs are particularly relevant in Troy given the mix of owner-occupied and rental housing in the city's residential neighborhoods.
Development Process
Development in Troy requires permits from the Building Department. The Planning Commission reviews site plans and zoning applications. The Zoning Board of Appeals handles variances. The city's Architectural Review Committee reviews projects in designated historic areas.
