At 10 FAR, a 10,000 square foot lot in M1-7A carries roughly 100,000 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.
A section through the M1-7A envelope, drawn to scale from the figures in the table above. The solid shape is as of right; where the district carries a City of Yes uplift, the dashed outline is what affordable housing adds.
Diagrammatic. It shows the governing heights and the setback on a regular lot, not your lot: the sky exposure plane, lot shape, corner conditions and any overlay all reshape this in practice.

The sentences below are quoted verbatim from the Zoning Resolution text the engine is built against, for the M1-7A rules we have mirrored and checked by hand. Check us against them.
“a setback with a depth of at least 10 feet from any street wall fronting on a wide street and a depth of at least 15 feet from any street wall fronting on a narrow street”
“a setback with a depth of at least 10 feet from any street wall fronting on a wide street”
“In all districts, as indicated, no side yards are required. However, if an open area extending along a side lot line is provided, it shall be at least eight feet wide.”
Use groups permitted in M1 districts:
M1-7A has a commercial far of 10, set by ZR 43-12. On a 10,000 square foot lot that is about 100,000 square feet of zoning floor area before any bonus, and before the height envelope and yard requirements are applied.
The maximum building height in M1-7A is 325 feet on a wide street, with a street wall rising to between 0 and 155 feet before a required setback. Height is measured and applied under ZR 43-12.
