Residential (1-acre min) — The base row is the RESIDENTIAL table. A nonresidential use in R-2 needs TWO acres, double the residential minimum. Density is one dwelling unit per 2 acres against a 1-acre minimum lot, so the two are different questions. Max 2 1/2 stories. The front yard is 75 ft on a STATE OR COUNTY HIGHWAY (schedule note 2, both tables). Minimum road frontage is 50 ft in every district. See § 250-15 for height exceptions. Conservation subdivision is available at Planning Board discretion under § 250-27 and Chapter 215 Article IV, outside the Prime Farmland Overlay District. Schedule note 1 exempts lots in a conservation subdivision from the minimum lot WIDTH above; the lot-size and density rules for them live in § 215-20, which this pass did not read.

Maximum building footprint for a nonresidential structure is 40,000 sq ft. A GREEN SPACE 35 ft deep from the right-of-way is required for residential use, with no buildings or parking in it (residential note 4). Max 3 stories.

The schedule publishes no yard, height or coverage figure for the district at all.

ADUs vs. short-term rentals in Kinderhook

No local short-term-rental law on record - which is not the same as permission for Town of Kinderhook. No STR-specific local law found for the Town of Kinderhook as of Jun 2026. Note: the Village of Kinderhook has its own STR law. Columbia County occupancy tax applies. 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.
