Town of West Seneca, NY: zoning for new construction

R-100A Residence - A two-family dwelling needs 1,200 sq ft of livable floor area rather than the 900 sq ft shown. The 10 ft side yard is the one-side minimum and the 20 ft beside it is the total for both sides, so both bind.

• A principal building that is not a dwelling takes 30 ft on each side, or the height of the building if that is greater
• The 30 ft height limit is for a one- or two-family dwelling; a multiple dwelling or any other principal building may reach 40 ft unless the Town Board approves more
• Where an apartment or two-family dwelling is permitted, the area of each dwelling unit must be approved by the Town Board
• The lot minimum here is flat and does not increase for a second dwelling unit
• An accessory building anywhere in a residence district is capped at 12 ft
• A lot less than a hundred feet deep need not hold a front yard deeper than the average of the principal buildings on the abutting lots fronting the same street

R-90 Residence, R-90A Residence - The 10 ft side yard is the one-side minimum and the 20 ft beside it is the total for both sides, so both bind. The 30 ft height limit is for a one- or two-family dwelling: a multiple dwelling or any other principal building may reach 40 ft unless the Town Board approves more.

• The lot minimum here does not increase for a second dwelling unit.
• An accessory building anywhere in a residence district is capped at 12 ft.

R-75 Residence, R-75A Residence - The lot minimum shown covers the first dwelling unit only, and a second unit adds both land and frontage, so a duplex needs more lot than the figure shown. The 5 ft side yard is the one-side minimum and the 10 ft beside it is the total for both sides.

• A two-family dwelling needs 1,200 sq ft of livable floor area rather than the 900 sq ft shown
• A multiple dwelling takes 25 ft to each side, or half the building height if greater, with both sides together twice one side, which the Town Board may reduce on special circumstances or hardship
