Village of Altamont, NY: zoning for new construction

Business - The 15 ft front setback is a minimum, and there is a ceiling as well: a building may sit no farther back than 30 ft. At least 20% of the lot has to stay uncovered and pervious, separate from the building coverage cap.

• A two-family dwelling needs a lot of at least 0.344 acre.
• A building that combines business use with an apartment has a lot minimum of 0.115 acre.

Central Business District - The 5,000 square foot lot minimum applies to commercial and mixed use buildings only, and the district sets none for a residential building, so confirm a housing plan with the village before counting on one.

• The 25 ft lot width is a minimum, and a lot may be no more than 80 ft wide.
• The front setback is a range: a building is placed at the edge of the sidewalk, up to a maximum setback of 10 ft.
• Side yards are not required, since zero lot lines are permitted, but a side yard that is provided has to be 12.5 to 20 ft.
• An accessory building keeps 5 ft to a side lot line.
• The 50 ft rear yard is there to make room for parking behind the building.

• The 40 ft front yard is a minimum with no published maximum, so a building may sit further back.

Park - The Park district carries no dimensional standard of its own in this code, and it is not included in the density and dimensional requirements chart. That is by design rather than an omission.

• Since this district has no dimensional standard of its own, confirm with the building department which requirements and approval path apply before planning any construction here.

Planned Unit Development - A planned unit development requires at least 40 acres to create. Setbacks, coverage and other dimensions are not published in advance; they are set at the time the planned unit development is reviewed and approved under § 355-14.
