Town of Rensselaerville, NY: zoning for new construction

Agricultural/Rural Residential - A two-family needs no extra land here: it sits on the same five acres as a one-family, and a multi-family keeps the five acres and 250 ft of frontage while its side and rear yards drop to 30 ft.

• A mobile home needs a 75 ft front yard rather than 50 ft, with 30 ft side and rear yards, on the same five acres.
• A nonresidential use needs 300 ft of frontage rather than 250 ft, and its building footprint may not exceed 4,000 sq ft.
• Agriculture is exempt from the lot area, height, frontage and coverage limits; yard setbacks still apply.
• Density is limited separately from lot size, and a lot may not exceed a 1:4 width to depth ratio.
• For a dwelling, the front yard and the frontage here are the same whether the lot fronts a town or private road or a county or state road.

Crystal Lake - Where an existing lot with deeded Crystal Lake rights is under two acres, its setbacks become those allowed for a one-family dwelling in the Hamlet district. On a county or state road the front yard is 20 ft rather than 15 and frontage 100 ft rather than 80.

• A mobile home matches a one-family in every dimension except building coverage, which is 20% rather than 25%.
• A two-family needs no more land here than a one-family does.
• Density is limited separately from lot size, and a lot may not exceed a 1:4 width to depth ratio.

Hamlet - A two-family needs one acre here, twice the half-acre a one-family needs, on otherwise identical frontage, yards, height and coverage. A multi-family keeps the half-acre minimum but needs 150 ft of frontage, or 200 ft on a county or state road.

• A multi-family also takes 20 ft side and rear yards rather than 15 ft.
• A nonresidential use needs one acre and 120 ft of frontage with 30 ft side and rear yards, and its building footprint may not exceed 4,000 sq ft.
• On a county or state road the front yard is 20 ft rather than 15 ft and the required frontage is 100 ft rather than 80 ft.
• Agriculture is exempt from lot area, height, frontage and coverage entirely, and only the yards apply.
• A new agricultural structure outside a New York State certified agricultural district may not stand within the 100 ft stream setback.
• Density is limited separately from lot size, and a lot may not exceed a 1:4 width to depth ratio.

Resource Conservation 1, Resource Conservation 2 - The front yard here is the figure for a lot on a town or private road. A dwelling on a county or state road needs 75 ft in front rather than 50 ft, and a mobile home takes the 75 ft front yard whichever road it fronts.

• A nonresidential building takes a 40 ft front yard on a town road but 100 ft on a county or state road, and its footprint may not exceed 10,000 sq ft.
• Agriculture is exempt from the lot area, height, frontage and coverage limits; yard setbacks still apply.
• RC-1, RC-2 and RC-3 carry identical dimensions and differ in which uses are permitted, not in bulk.
• Density is limited separately from lot size, and a lot may not exceed a 1:4 width to depth ratio.

Resource Conservation 3 - The front yard here is the figure for a lot on a town or private road. A dwelling on a county or state road needs 75 ft in front rather than 50 ft, and a mobile home takes the 75 ft front yard whichever road it fronts.

• A nonresidential building takes a 40 ft front yard on a town road but 100 ft on a county or state road, and its footprint may not exceed 10,000 sq ft.
• RC-1, RC-2 and RC-3 carry identical dimensions and differ in which uses are permitted, not in bulk.
• Density is limited separately from lot size, and a lot may not exceed a 1:4 width to depth ratio.
