RF-1 Rural Farmland, RF-2 Rural Farmland, R-40 Residential, LI Light Industrial, HI Heavy Industrial — Base density and the maximum number of dwelling units on a parcel — or of new parcels a subdivision may create — are CALCULATED under § 123-24B, not read off this schedule (schedule note 1). Further lot and yard regulations are in § 123-24E through I (note 2).
R-12 Residential — THE BASE ROW IS THE MOST PERMISSIVE CASE. R-12 publishes three rows and 12,500 sq ft applies only where the lot is served by BOTH central sewer and central water. The middle row — central sewer OR water — requires 25,000 sq ft at 17.5% coverage, with the same 100 ft width and depth and the same 30/15/30 yards. That row is a disjunction, exactly one utility, which a conjunctive `when` cannot state without restating this basis, so it is recorded here rather than as a variant. The no-utilities row IS a variant. Base density and the maximum number of dwelling units on a parcel — or of new parcels a subdivision may create — are CALCULATED under § 123-24B, not read off this schedule (schedule note 1). Further lot and yard regulations are in § 123-24E through I (note 2).
RG Residential Gateway, BC Bluestone Commercial — The schedule row is "RG and BC, served by Central S and W", so the base figures assume both utilities. Front yard is a RANGE: 4 ft minimum and 10 ft maximum — the 4 ft recorded above is the minimum. The schedule states no minimum lot depth. Base density and the maximum number of dwelling units on a parcel — or of new parcels a subdivision may create — are CALCULATED under § 123-24B, not read off this schedule (schedule note 1). Further lot and yard regulations are in § 123-24E through I (note 2).
NC Neighborhood Commercial — A RESIDENCE in NC takes the R-12 District's lot area and dimensions, not these (schedule note 3); the base row is the nonresidential standard. Base density and the maximum number of dwelling units on a parcel — or of new parcels a subdivision may create — are CALCULATED under § 123-24B, not read off this schedule (schedule note 1). Further lot and yard regulations are in § 123-24E through I (note 2).
GC-1 General Commercial — A RESIDENCE in GC-1 takes the R-12 District's lot area and dimensions, not these (schedule note 3); the base row is the nonresidential standard. Base density and the maximum number of dwelling units on a parcel — or of new parcels a subdivision may create — are CALCULATED under § 123-24B, not read off this schedule (schedule note 1). Further lot and yard regulations are in § 123-24E through I (note 2).
GC-2 General Commercial — A RESIDENCE in GC-2 takes the R-12 District's lot area and dimensions, not these (schedule note 3); the base row is the nonresidential standard. Base density and the maximum number of dwelling units on a parcel — or of new parcels a subdivision may create — are CALCULATED under § 123-24B, not read off this schedule (schedule note 1).

W Waterfront — The schedule states no minimum lot area, no minimum lot depth and no maximum coverage for W. Base density and the maximum number of dwelling units on a parcel — or of new parcels a subdivision may create — are CALCULATED under § 123-24B, not read off this schedule (schedule note 1).

Further lot and yard regulations are in § 123-24E through I (note 2).
ADUs vs. short-term rentals in Esopus
Short-term rentals allowed with local rules for Town of Esopus. Short-term rental is a defined and regulated use in the Town of Esopus. § 123-61 of Zoning Chapter 123 defines SHORT-TERM RENTAL as an accessory use or supplementary business letting a dwelling for less than 30 days, and splits it into SHORT-TERM RENTAL, OWNER-OCCUPIED and SHORT-TERM RENTAL, NON-OWNER-OCCUPIED — a split that normally carries different permissions by district. New York State's 2025 short-term rental registry (Ch. 99 of the Laws of 2025) separately requires every host statewide to register the unit regardless of local law. Confirm with Town of Esopus at (845) 338-6671 before listing. 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. Municipal source
