Village of Montgomery, NY: zoning for new construction

Residential One-Family - The lot size shown is for land with both public sewer and public water. With only one of them a lot needs at least twenty thousand square feet, and with neither, building here is not permitted.

• The pair of side yards must total at least forty feet, so a house needs at least twenty-five feet on one side and at least fifteen on the other.
• A side yard on the street side of a corner lot must be at least thirty-five feet.
• Lot width is measured at the required minimum front yard depth, not at the street.
• Coverage counts main and accessory buildings together.
• An accessory building may cover up to 20% of the required rear yard, rise no more than 18 feet there, and must stand at least 5 feet from any lot line.
• Only a single-family detached dwelling is permitted; a two-family house, a multiple dwelling and a planned residential development are not.

Residential Agriculture One-Family - The lot size shown is for land with both public sewer and public water. With only one of them a lot needs at least eighteen thousand square feet, and with neither at least twenty thousand; RA-3 is the only district in the Village buildable without any public service.

• A side yard on the street side of a corner lot must be at least thirty-five feet, the full front-yard figure.
• A planned residential development, and a golf course or country club on at least fifty acres, are available by special exception.

Residential One- and Two-Family - Nothing may be built here without both public sewer and public water. Each dwelling unit needs at least twenty-five hundred square feet of land, so the minimum lot carries a two-family house exactly and the per-unit figure is what binds.
