What can you build in R6A?

R6A is a contextual medium-density district for mid-rise apartment buildings with street walls built close to the sidewalk.
Floor area (FAR)
- Standard maximum residential FAR: 3.00 (ZR 23-22).
- With qualifying affordable housing or qualifying senior housing: 3.90 FAR.
- Community facility FAR: 3.00, with lot coverage up to 80% on corner lots and 60% 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 40 ft and at most 65 ft before a setback; maximum building height 75 ft. With qualifying affordable or senior housing: base up to 65 ft, building up to 95 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).

City of Yes changes
- City of Yes for Housing Opportunity (adopted December 5, 2024) set separate limits for qualifying affordable housing (Mandatory Inclusionary Housing developments, Universal Affordability Preference (UAP) developments, or buildings under an affordable housing regulatory agreement) and qualifying senior housing. In R6A they can reach 3.90 FAR versus 3.00 for standard buildings, with taller height limits (ZR 23-22, 23-432, 12-10).
- Buildings in R6 through R12 have no front yard requirement, and lot coverage is 80% on interior lots and 100% on corner lots (ZR 23-322, 23-362).

On a 25 x 100 ft lot (2,500 sq ft) at the standard 3.00 FAR, the maximum residential floor area is 7,500 sq ft. Dividing by the dwelling unit factor of 680 gives 11.03, so about 11 units (a fraction of 0.75 or more counts as one more unit). Qualifying senior housing has no unit cap from this rule (ZR 23-52).
What does the letter A in R6A mean?
Letter suffixes mark contextual districts, which aim to keep or set a neighborhood's building scale (ZR 11-121). In practice R6A has its own height and floor area rows in the zoning tables, separate from plain R6.
