City Context

How is Buffalo zoned?

Buffalo regulates land through 22 zoning districts under a form-based code that splits the roster into two families. N marks neighborhood zones and D marks districts, and within each the code describes character rather than use.

The neighborhood zones are numbered by intensity and lettered by role: residential, mixed use edge, mixed use center, mixed use core, single family and a secondary employment center. N-3R, a residential neighborhood zone, is the largest district in the city at roughly 6,118 acres.

The two single family zones carry a further number, at 30 and 50, which distinguishes them by lot standard.

The D districts are named rather than numbered, covering light and heavy industrial, flex commercial, strip retail, and four campus or open space categories: residential campus, educational campus, medical campus, plus a Green district, a Natural district and a Square district.

Naming a Green district at roughly 2,839 acres, the second largest classification, and a separate Natural district at about 496, distinguishes managed green space from land left in its natural state. The Square district at roughly 23 acres covers Buffalo's historic public squares.

A Corridor Rail district covers roughly 996 acres, zoning rail corridors explicitly. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
