Town of Wallkill, NY: zoning for new construction

Rural-Agricultural - The two-acre lot minimum is only a floor: § 249-19 sets the lot through the environmental control formula, so a parcel with poor soils, wetland, floodplain or steep slope needs more than two acres.

• At least two hundred feet of lot frontage is required as well as the lot width.
• A second detached dwelling is permitted on a lot big enough to subdivide under the formula, if both are in common ownership and each could meet the district's yard and size requirements on its own.
• Subdivision approval for a second detached dwelling must be obtained before either unit is sold.
• Keeping livestock needs at least eighty thousand square feet for the first animal and another forty thousand for each animal after it.
• Livestock structures must be at least a hundred feet from any property line and two hundred from a residential district line, or fifty and a hundred if twenty-six feet or less in height.
• Pigs and mink are not permitted.

Low-Density Agricultural - The three acres shown apply to a Type II conservation subdivision under § 249-80, and a conventional Type I subdivision needs at least five acres. Both are floors under the environmental control formula, so a parcel with poor soils, wetland, floodplain or steep slope needs more.

• At least two hundred and fifty feet of lot frontage is required as well as the lot width.

Suburban Residential - The acre and a half shown applies whether the lot has both public water and public sewer or only one of them. A lot with neither service is sized through the soil and drainage review rather than by a set figure.

Medium-Density Residential - The lot shown applies whether the lot has both public water and public sewer or only one of them; a lot with neither is sized through the soil and drainage review. Multiple dwellings need a site of at least ten acres, with land per unit graded by the number of habitable rooms.

• A Type II conservation subdivision under § 249-80 halves the land required per unit.

Multiple-Family (Bonus) Residential - Land per dwelling unit controls the count: each unit needs at least 3,900 sq ft of land for an efficiency, 4,800 for a one-bedroom, 7,200 for a two-bedroom and fourteen thousand five hundred for a three-bedroom.

• The land counted excludes bodies of water, wetlands, land subject to flooding and ponding, slopes over twenty percent, and existing rights-of-way and easements.
• Minimum liveable floor area rises with the unit from six hundred square feet to a thousand, and parking from 1.25 spaces to 2.5.
• At least a hundred and fifty feet of lot frontage is required as well as the lot width.

Airport Residential - The residential figures shown hold for a lot with both public water and public sewer, and the lot area is the same with public sewer alone. A lot with neither is sized by the environmental control formula and needs at least twenty thousand square feet.

• A nonresidential use has its own standards, including a lot of at least forty thousand square feet.
• All unbuilt and unpaved areas of a lot must be graded, drained and continuously maintained with landscaping the Planning Board approves.

Neighborhood Commercial - The figures shown are for commercial use on a lot with both public water and public sewer. Commercial floor area is capped at five thousand square feet, and where a lot adjoins RA, R-1 or R-2 its side and rear yards must meet that district's requirements instead.

• A one-family dwelling must have at least six hundred square feet of floor area.
• The permitted uses are offices, retail stores, personal service shops, dry-cleaning and laundry establishments, appliance repair and printing shops.
• All uses except off-street parking must be carried on within fully enclosed buildings.

Highway Commercial - Residential construction follows the standards in § 249-20D rather than the figures shown.

• Special permit uses and overlay districts may add standards on top of these.

Town Center - The rear yard must be at least fifty feet or the height of the building, whichever is greater, so a building at the sixty-foot height limit needs sixty feet at the back.

• Special permit uses or overlay districts may add standards on top of these.

Office and Research - The 100 ft height limit drops to forty-five feet for any structure within a hundred feet of a preexisting residential use, measured at the lot line, or of a residential district.

• The Planning Board may waive the height limit altogether for a hospital, provided the structure is not within a hundred feet of a preexisting residential use or district.
• The rear yard must be at least thirty feet or the height of the building, whichever is greater, so a hundred-foot building needs a hundred feet at the back.
• The Planning Board may not entertain an application for a distribution facility until the Town Board adopts a resolution supporting it.
• A distribution facility's property must already have been served by the municipal water and sewer districts when that provision took effect.

Enterprise - The side yard must be at least twenty feet or the height of the building, whichever is greater, so a building at the thirty-five-foot height limit needs thirty-five feet on each side. All nonresidential development must buffer adjacent preexisting residential uses.

• Outdoor storage of building supplies, raw material or equipment may not exceed the height of any wall or fence around it.
• Liquids may be stored underground, subject to the fire and building codes.
• Special permit uses or overlay districts may add standards on top of these.

Light Enterprise - The side yard must be at least twenty feet or the height of the building, whichever is greater. All nonresidential development must buffer adjacent preexisting residential uses.
