R7X Zoning in NYC: FAR, Height and Setbacks

R7X is the densest R7 contextual district, for apartment buildings up to 125 ft (145 ft with qualifying affordable or senior housing).

Floor area (FAR)

• Standard maximum residential FAR: 5.00 (ZR 23-22).
• With qualifying affordable housing or qualifying senior housing: 6.00 FAR.
• Community facility FAR: 5.00, with lot coverage up to 80% on corner lots and 70% on interior or through lots (ZR 24-11). Some uses, such as non-profit institutions with sleeping accommodations, can have lower limits (ZR 24-111).
• FAR (floor area ratio) is total zoning floor area divided by lot area. On a 2,500 sq ft lot, 1.00 FAR means 2,500 sq ft of floor area.
• Maximum dwelling units: residential floor area divided by 680, the dwelling unit factor (no factor for qualifying senior housing) (ZR 23-52).

Height and setbacks

• Street wall rises to at least 60 ft and at most 95 ft before a setback; maximum building height 125 ft. With qualifying affordable or senior housing: base up to 105 ft, building up to 145 ft (ZR 23-432).
• Above the base, the building must set back at least 10 ft from a wide street or 15 ft from a narrow street; the setback can shrink 1 ft for each foot the street wall sits back from the street line, to no less than 7 ft (ZR 23-433).
• At least 70% of the street wall must sit within 8 ft of the street line on a wide street, or within 10 ft on a narrow street (ZR 23-431).

Yards, lot coverage and lot size

• Front yard: None required (ZR 23-322).
• Side yards: Detached one- or two-family houses need two side yards of at least 5 ft each. Other buildings need none, but any open area along a side lot line must be at least 5 ft wide (ZR 23-335).
• Rear yard: On interior lots, detached and zero lot line buildings need a 20 ft rear yard up to 75 ft high. Semi-detached and attached buildings need 30 ft on lots narrower than 40 ft, and 20 ft on lots 40 ft or wider. Where a building rises above 75 ft, that portion needs 30 ft (ZR 23-342). Shallow lots that existed in 1961 can get a reduced rear yard, never under 10 ft.
• Lot coverage: 80% on interior and through lots, 100% on corner lots (ZR 23-362).
• Minimum lot size: 2,375 sq ft and 25 ft wide for a detached or zero lot line one- or two-family house; 1,700 sq ft and 18 ft wide for other residences (ZR 23-12).
