Yonkers, NY Building Setbacks & Zoning: Lot Coverage Limits (2026)

Yonkers regulates bulk primarily through floor area ratio and height, and the citywide, district-by-district maximum building coverage percentages for principal structures sit in Table 43-3, the Schedule of Dimensional Regulations, which is issued as a separate attachment to Chapter 43 rather than printed in the body of the ordinance supplied here. What is printed in the body is the coverage cap on accessory structures under Section 43-40D(2): more than one accessory building or structure is allowed on a lot only if their combined footprint does not cover more than 60% of the rear yard, more than 60% of each side yard, or a combined 75% of the rear and side yards together.

That cap applies on top of the separate setback rules in Section 43-40D(4), which keep accessory structures at least three feet from a side line and five feet from a rear line, and the one-story, 15-foot height limit in Section 43-40D(3). The code also uses lot coverage as a control for specific institutional and commercial uses: places of worship are capped at 40% building coverage in residential districts and 60% elsewhere under Section 43-35C(4), and freestanding automobile repair shops are capped at 60% overall coverage by pavement and buildings, with the building itself limited to 30% of the lot, under Section 43-38B(3).
