Zoning allows more floor area than the building uses: roughly 1,219 sq ft of unused development rights on paper. Zoning bonuses, overlays and lot conditions change the real number; an architect should confirm it.

NYC rules that apply here

Based on the building’s size, age and type. These apply whether or not anything is open.

• HDFC (Article XI)A Housing Development Fund Corporation under Article XI of the NY Private Housing Finance Law: usually a limited-equity co-op that the city sold to its tenants, or a non-profit-owned affordable building. Run by a resident board, usually volunteers, so the compliance calendar is the board’s job and often falls behind. The property-tax exemption is tied to a regulatory agreement with HPD, which can step in if the building is mismanaged or in distress.
• Former city-owned (DAMP)DOF taxes the lot under its DAMP exemption schedule, used for buildings HPD sold out of city ownership through its alternative-management programmes (most became HDFC co-ops, often through Tenant Interim Lease). The tax benefit phases by schedule, so the bill rises over the years; check the schedule number on the DOF notice. The sale came with conditions recorded against the property; read the deed and regulatory agreement before advising the board.
• Class B / SRO roomsHPD records lawful Class B (rooming or single-room-occupancy) units here. Single-room-occupancy buildings need HPD’s Certification of No Harassment before DOB approves most demolition or alteration work. Rooms in older SRO buildings are commonly rent-stabilised.
• HPD registration if rented outA one- or two-family home must register with HPD when neither the owner nor the owner’s family lives there. Read the guide
• Lead-paint rules for rented unitsBuilt before 1960: an apartment rented to a tenant falls under Local Law 1 (presumed lead paint, turnover work, records). Read the guide
• Natural gas alarms by January 1, 2027Every apartment in a building with gas service needs a natural gas alarm (Local Law 157 of 2016, deadline set by Local Law 102 of 2025). Read the guide
