Town of Webster, NY: zoning for new construction

R-1 Single-Family Residential - The 75 ft front setback shown applies to an ordinary interior lot. It rises to 85 ft on a major highway, drops to 65 ft on a corner lot, and is 75 ft on a corner lot on a major highway.

• A nonresidential use takes a separate lot minimum of 5 acres, several times the residential figure; the width, setbacks, height and coverage are unchanged.
• A dwelling of more than one storey must have at least 2,160 sq ft of habitable floor area; the 1,440 sq ft figure is the one-storey case.
• On a flag lot, the minimum lot area must be held by the flag portion alone, behind the access strip; the pole is excluded.
• A lot on the exterior arc of a curve or cul-de-sac may narrow to 55 ft at the front lot line tangential to the arc.
• A driveway must stay 5 ft from the side lot line rather than meet the structure setback, except on a flag lot or a common driveway.

R-2 Single-Family Residential - The 60 ft front setback shown is for an ordinary interior lot. It becomes 70 ft on a major highway, 50 ft on a corner lot, and 60 ft on a corner lot on a major highway.

• A nonresidential use takes a separate lot minimum of 3 acres, several times the residential figure; the width, setbacks, height and coverage are unchanged.
• Minimum habitable floor area is 1,320 sq ft only for a one-storey dwelling; anything over one storey must have 1,800 sq ft.
• On a flag lot, the minimum lot area must be held by the flag portion alone, since the access pole is excluded, so the full minimum sits behind the strip.
• A lot on the exterior arc of a curve or cul-de-sac may narrow to 55 ft at the front lot line tangential to the arc.
• A driveway must stay 5 ft from the side line rather than meeting the structure setback, except on a flag lot or a common driveway.

• A nonresidential use takes a separate lot minimum of 2 acres, several times the residential figure; the width, setbacks, height and coverage are unchanged.
• A dwelling over one storey must have at least 1,560 sq ft of habitable floor area; the 1,200 sq ft figure is the one-storey case.
• On a flag lot, the minimum lot area must be met within the flag portion alone, since the access pole is excluded from the area.
• A lot on the exterior arc of a curve or cul-de-sac may narrow to 55 ft at the front lot line tangential to the arc.
• A driveway must be kept 5 ft from the side lot line rather than at the structure setback, except on a flag lot or a common driveway.

• A driveway is held to 5 ft from the side line rather than the 15 ft structure setback, except on a flag lot or a common driveway.
• The district states no maximum lot coverage, and its stated intent is to keep both residential density and the amount of land under impervious surface low.

MHR Medium-High Residential - The figures shown cover single-family detached and semidetached homes only. Two-family, multiple-family, townhouse and garden home forms each carry their own lot minimum and dimensional standards. Total impervious area across the district is capped at 75%.

• A two-family dwelling takes 15,000 sq ft on the same 80 ft of width, with a 15 ft side yard, coverage raised to 25%, a 70 ft front setback on a major highway and 1,500 sq ft of floor area.
• A multiple-family development needs 5 acres at eight units per acre, a 75 ft front setback, three storeys, 40 ft between structures, and buildings to 250 ft with 25 ft paved access.
• Garden homes carry the largest threshold here: a ten-acre lot, eight units per acre, 1,000 sq ft per unit, 20 ft unit width, and a 50 ft buffer rising to 100 ft beside a single-family district.
