Village of Webster, NY: zoning for new construction

Residential R-1-13.6 District - Under § 175-11A(2), 50% in number of the lots on any subdivision plan must be at least 16,000 sq ft, so the minimum shown is the floor for an individual lot, not an achievable average across a plan.

• Where principal structures front the same street within 300 ft of either side line, the front yard is the average of the nearest setbacks on each side, never less than 20 ft.
• With a principal structure on one side only, the front yard is the average of that setback and 40 ft, again never less than 20 ft.
• On a lot under 70 ft wide held in separate ownership when the chapter took effect, the 20 ft side yard total drops one foot per foot under 70, to no less than 12 ft.
• Once that reduced side yard total is below 16 ft, the two side yards must be equal.
• The 30 ft height limit is for dwellings and structures attached to them. Detached garages are limited to 18 ft and accessory buildings to 10 ft.
• Lot coverage counts all buildings, accessory buildings included.

Residential R-1-9.6 District - The front yard is contextual: where principal structures front the same street within 300 ft of either side line, the depth is the average of the nearest setbacks on each side, never under 20 ft. With a structure on one side only, it is the average of that setback and 40 ft.

• On a lot under 60 ft wide held in separate ownership when the chapter took effect, the 16 ft side yard total drops six inches per foot under 60, to no less than 10 ft.
• Once that reduced side yard total is below 12 ft, the two side yards must be equal.
• The 30 ft height limit is for dwellings and structures attached to them. Detached garages are limited to 18 ft and accessory buildings to 10 ft.
• Lot coverage counts all buildings, accessory buildings included.

Residential R-2-9.6 District - The figures shown are for a single-family dwelling. The front yard is contextual: where principal structures front the same street within 300 ft of either side line, the required depth is the average of the nearest setbacks on each side, never less than 20 ft.

• A two-family dwelling is a controlled site use needing site plan approval: 18,000 sq ft on 100 ft of width, with the two side yards totalling 26 ft and neither under 10 ft.
• Townhouses are sized by density: 2,000 sq ft per dwelling unit, a minimum of 1 acre for each group, and a hard cap of 8 units per acre, which is what binds.
• With a principal structure on one side only, the front yard is the average of that setback and 40 ft.
• On a lot under 60 ft wide in separate ownership when the chapter took effect, the 16 ft side yard total drops six inches per foot under 60, to no less than 10 ft, and splits equally below 12 ft.
• The 30 ft height limit is for dwellings and attached structures; detached garages are limited to 18 ft and accessory buildings to 10 ft, and lot coverage counts all buildings.

Residential RM District - The figures shown are for a single-family dwelling, and the 35 ft height covers single-family, two-family and townhouse buildings only. Two-family, townhouse, multiple-family and condominium development all require site plan review under Article XIV.

• A two-family dwelling is a controlled site use needing site plan approval: 18,000 sq ft on 100 ft of width, with the two side yards totalling 26 ft and neither under 10 ft.
• Townhouses are sized by density: 2,000 sq ft per dwelling unit, a minimum of 1 acre for each group, a hard cap of 8 units per acre, and a 40 ft side yard.
• A multiple-family dwelling needs 20,000 sq ft for the first 2 units plus 3,000 sq ft for each beyond, on 150 ft of width, and stands twice its height from a side or rear line, 80 ft at 40 ft.
• Where structures front the same street within 300 ft of either side line, the front yard is the average of the nearest setbacks, never under 20 ft; with one side only, the average of it and 40 ft.
• On a lot under 60 ft wide in separate ownership when the chapter took effect, the 16 ft side yard total drops six inches per foot under 60, to no less than 10 ft, and splits equally below 12 ft.
• Lot coverage counts all buildings, accessory buildings included.
