Zoning allows more floor area than the building uses: roughly 4,740 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.

• 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.
• Rent-stabilised unitsThe DOF property tax bill lists rent-stabilised units in this building. Every stabilised unit must be registered with DHCR each year, with the rent roll. Increases follow the Rent Guidelines Board; leases, renewals and riders use the required forms.
• Sidewalk shed / scaffold upAn active DOB NOW permit for a sidewalk shed, scaffold or construction fence. A shed is a monthly rental cost, and one that stays up for years usually means facade repairs are stalled. The permit has to be renewed while the shed stands; an expired shed permit is a violation.
• LL97 Article 321On DOB’s Local Law 97 list under Article 321 (certain affordable housing and houses of worship). Instead of yearly caps, a one-time compliance: the listed prescriptive energy measures, or meeting the 2030 limits, documented in a report to DOB. The report was due in 2025; DOB issues violations to buildings that did not file.
• LL87 energy auditOn DOB’s Local Law 87 list: an energy audit and retro-commissioning report every ten years, the year set by the block number’s last digit.
• LL88 lightingOn DOB’s Local Law 88 list: lighting in non-residential and common spaces had to meet code by January 1, 2025 (and tenant submeters in the largest buildings), with a report to DOB.
• Gas piping inspection every four years (Local Law 152)Every building except one- and two-family homes; the year depends on the community district. Read the guide
• Façade inspection every five years (FISP / Local Law 11)Taller than six stories, so a qualified inspector must examine the exterior walls every five years and file with DOB. Read the guide
• Energy benchmarking and Local Law 97About 69,289 sq ft, over the 25,000 sq ft line: Local Law 84 benchmarking and the Local Law 97 emissions report are due May 1 if the building is on the covered list. Over 50,000 sq ft, a Local Law 87 energy audit is due every ten years. Read the guide
