ADU · Greene County
Can you build an ADU in Coxsackie, NY?
Town of Coxsackie has 10 districts. All districts prohibit ADUs. Check your address to confirm the district that applies to your parcel:
What the Coxsackie code says
Coxsackie's code defines an accessory apartment, but no district lists one as a permitted use, so an accessory dwelling unit is not available. The second-unit option in the code is the two-family dwelling.
Conditions the code attaches:
- A two-family dwelling is allowed by right in some residential districts and only by special permit in others, so check which rule applies to the parcel.
- A two-family dwelling is not available in WR.
- The accessory apartment term appears only in the senior citizen and handicapped housing provision, where occupancy is limited by age or disability and runs through a Planned Development District.
- MU also permits multifamily dwellings by right.
- Confirm any second-unit plan with the building department at (518) 965-3628.

Waterfront Residential District - The front yard here is 150 feet from the high water line, measured horizontally away from and paralleling the river, not from the front lot line. The 70% coverage figure is a cap on impervious surface, not on the building footprint.
- The rear yard of 20 feet is also measured from the high water line, not from the rear lot line.
- Density is calculated after excluding all water bodies, watercourses and wetlands from the land area.
- Land of 50% slope or greater is excluded too, and half of all land with a slope over 15% and under 50%.
- Areas of significant wildlife habitat, including landscape linkages and wildlife corridors, are also excluded from the density calculation.
Residential Agricultural-1 District, Residential Agricultural-2 District - The front yard is 100 feet from the center line on a state road and 75 feet from the center line of any other road, measured from the road rather than from the front lot line. The building may cover 20% of the lot and impervious surface 30% in total.
- On a road of more than two lanes the front setback is measured from the center of the two closest lanes.
- Accessory uses are limited to 10% of the lot within that 30% impervious total.
- Density is calculated after excluding all water bodies, watercourses and wetlands from the land area.
- Land of 50% slope or greater is excluded too, and half of all land with a slope over 15% and under 50%.
- Areas of significant wildlife habitat, including landscape linkages and wildlife corridors, are also excluded from the density calculation.
Rural Residential District - The front yard is 100 feet from the center line on a state road and 75 feet from the center line of any other road, measured from the road rather than from the front lot line. The building may cover 20% of the lot and impervious surface 30% in total.

- The overlay also allows that density across a tract in a cluster development that keeps at least 50% of the tract as open space.
- Density is calculated after excluding water bodies, watercourses, wetlands, land of 50% slope or greater, half of land between 15% and 50% slope, and significant wildlife habitat.

- A multifamily dwelling needs 2,200 square feet of land per unit, and a single-family semidetached, single-family attached or two-family dwelling 2,500 square feet per unit, on top of the lot minimum.
- The front of a building must also stand 100 feet from the center line on a state road and 75 feet from the center line of any other road.
- On a road of more than two lanes that front measurement runs from the center of the two closest lanes.
- The 50% coverage figure is a cap on impervious surface, not on the building footprint, and accessory uses are held to 10%.

ADUs vs. short-term rentals in Coxsackie
No local short-term-rental law on record - which is not the same as permission for Town of Coxsackie. The Town of Coxsackie has no local short-term rental law. That is not the same as permission, so confirm with the town before counting on rental income. These are separate questions from whether you can build an ADU — a unit you're allowed to add isn't automatically one you're allowed to rent nightly, so check both.
