Rural Agricultural (5-acre) — Maximum footprint of the principal building 10,000 sq ft — a square-foot cap, not a percentage, which is why no coverage figure is recorded. Minimum ROAD FRONTAGE is 60 ft — Schedule 1 publishes a road frontage but NO minimum lot width, which is why that field stays empty. The front setback is measured from the CENTRE OF THE TRAVELLED PORTION OF THE ROAD (schedule note 3), not from the property line. Overlay districts carry additional area and bulk requirements of their own (note 1).
Rural Agricultural (2-acre), Rural Agricultural (1-acre) — Maximum footprint of the principal building 4,000 sq ft — a square-foot cap, not a percentage.

Overlay districts carry additional area and bulk requirements of their own (note 1).
Commercial — The 30,000 sq ft minimum does NOT apply to a wholesale store, hotel or motel, each of which needs two acres (note 4). The side yard becomes 50 ft where the lot adjoins a RESIDENTIAL ZONE and 40 ft where it adjoins an existing building (note 5) — both larger than the figure above, and adjacency is not a condition axis. Minimum ROAD FRONTAGE is 100 ft — Schedule 1 publishes a road frontage but NO minimum lot width, which is why that field stays empty. The front setback is measured from the CENTRE OF THE TRAVELLED PORTION OF THE ROAD (schedule note 3), not from the property line. Overlay districts carry additional area and bulk requirements of their own (note 1).
Commercial Corridor — The front setback is a RANGE: 50 ft minimum and 100 ft MAXIMUM. The 30,000 sq ft minimum does NOT apply to a wholesale store, hotel or motel, each of which needs two acres (note 4).

Commercial Industrial — C-I is the one commercial district whose 30,000 sq ft minimum carries no wholesale/hotel exception.

Commercial Residential — THE BASE ROW IS THE RESIDENTIAL CASE. Schedule note 2 gives C-R no figures of its own: a RESIDENTIAL use takes the RA-1 District's area and bulk regulations, which is what the base row holds, and a COMMERCIAL use takes the Commercial District's — recorded as a variant. Minimum ROAD FRONTAGE is 60 ft — Schedule 1 publishes a road frontage but NO minimum lot width, which is why that field stays empty. The front setback is measured from the CENTRE OF THE TRAVELLED PORTION OF THE ROAD (schedule note 3), not from the property line.

ADUs vs. short-term rentals in New Lebanon
Short-term rentals allowed with local rules for Town of New Lebanon. Local Law No. 3 of 2023 (zoning amendments adopted Aug 2023) includes STR provisions requiring a local contact person within 20 miles and prohibiting STR use of ADUs for three years post-CO. 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.
