These are the figures the engine applies when it models a lot in C2-8. Where a rule differs between a narrow and a wide street, both are shown.
| Commercial FAR | 2 | ZR 33-12 |

| Residential bulk equivalent | R10 | ZR 34-112 |
| Front yard | 0 ft | ZR 23-45 |

At 2 FAR, a 10,000 square foot lot in C2-8 carries roughly 20,000 square feet of zoning floor area.
That is the ceiling, not the answer. The height envelope, required yards, lot shape, street width, overlays and any special district all cut into it. Running the real lot is the only way to know which constraint binds first.
Every area of the city zoned C2-8, from NYC Planning’s published zoning district layer.
The sentences below are quoted verbatim from the Zoning Resolution text the engine is built against, for the C2-8 rules we have mirrored and checked by hand. Check us against them.
“Within C1-7 C1-8 C1-9 C2-7 C2-8 C4-2F C4-6 C4-7 C4-8 C4-9 C4-11 C4-12 C5 C6 C8-4 Districts”
“In C1 and C2 Districts mapped within, or with a residential equivalent of, R6 through R12 Districts with a letter suffix, a rear yard equivalent shall be provided only as set forth in this paragraph.”
“a rear yard with a depth of not less than 20 feet shall be provided at every rear lot line”
“In all districts, as indicated, no side yards are required.”
“85 feet or six stories , whichever is less”
Use groups permitted in C2 districts:
Underbuilt here means a lot of at least 2,500 square feet, built to less than half its residential floor area, in private hands, with at least 20,000 square feet of unused capacity. From PLUTO 26v2. How we counted.
C2-8 has a commercial far of 2, set by ZR 33-12. On a 10,000 square foot lot that is about 20,000 square feet of zoning floor area before any bonus, and before the height envelope and yard requirements are applied.
C2-8 is not governed by a flat height cap in the quality housing tables; height is controlled by the sky exposure plane and the bulk rules shown above.
