Buffalo, NY Zoning

21 districts. 3 overlays.
This profile is an earlier edition — some fields may be incomplete. An updated profile is in progress.

Overview

Worth knowing
  • Form-based code — NOT Euclidean; form and character are the primary regulatory framework, not use separation [confirmed]
  • Dynamic height formula in N-1D (1.75× street width) and N-1C (1.25× street width) — no fixed height cap in these zones [confirmed §3.2]
  • No FAR, density caps, or minimum front setbacks — these traditional Euclidean controls are eliminated entirely [confirmed]

Quirks & notes

  • Form-based code — NOT Euclidean; form and character are the primary regulatory framework, not use separation [confirmed]
  • Dynamic height formula in N-1D (1.75× street width) and N-1C (1.25× street width) — no fixed height cap in these zones [confirmed §3.2]
  • No FAR, density caps, or minimum front setbacks — these traditional Euclidean controls are eliminated entirely [confirmed]
  • Height transitions at zone boundaries — 1 ft additional setback per 1 ft of height above abutting residential zone maximum [confirmed §3.2]
  • Mandatory building type compatibility per zone — each zone lists permitted building types with type-specific dimensional standards [confirmed §3.2]
  • Minimum height requirements in TOD overlay (2-3 stories) — density floors, not ceilings [confirmed §5.1]
  • Residential density minimums (not maximums) in TOD — 18-36 du/ac floors depending on sub-zone [confirmed §5.1]
  • Zero parking minimums across all zones — no off-street parking requirement for any use [confirmed §8.3]
  • Waterfront yard depths of 25 ft or 100 ft with 50 ft native vegetation buffer in C-W overlay [confirmed §5.3]
  • Build-to zone mechanics replace traditional setback lines — facade must be placed within a defined distance range from property line [confirmed]

Formulas

Definitions

height
Measured in stories and feet; varies by building type within each zone. N-1D uses 1.75× street width formula; N-1C uses 1.25× street width formula. §3.2
lot_coverage
Building footprint / lot area. Stated for some district zones (e.g., D-C 0.90). Not a primary control in neighborhood zones — building type standards govern instead.
far
du_ac
setback_front
Eliminated. Replaced by build-to zones — front facade must be placed within a defined distance range from the front property line. §3.2
setback_side
Set per building type; many types require 0 ft (attached buildings). Detached types use percentage of lot width. §3.2
setback_rear
Set per building type; detached types use percentage of lot depth. §3.2
parking
Zero parking minimums across all zones. §8.3
transparency
Minimum percentage of ground-floor facade that must be transparent (windows/doors). Set per zone; up to 70% in N-1D/N-1C. §3.2
build_to_zone
Distance range from front property line within which the primary facade must be placed. Replaces traditional setback lines. §3.2
building_type
Each zone has a list of permitted building types (e.g., Commercial Block, Shopfront, Attached House, Detached House) with type-specific dimensional standards. §3.2
height_transition
At zone boundaries abutting residential: 1 ft additional setback per 1 ft of height above the abutting residential zone maximum. §3.2
