Waterfront Conservation — Residential uses in the WC District carry additional special permit criteria under § 143-53. Minimum lot width is 500 ft and minimum frontage 300 ft — separate columns, and the frontage is always the smaller. Every yard column prints two figures. The first is the principal structure and is the one recorded here; the second is the minimum setback for OFF-STREET PARKING and its accessways — 60 ft front, 50 ft side, 50 ft rear — which binds separately, and does not apply to a driveway serving a one- or two-family dwelling (Note 1). A minimum of 90% of the lot must be open space. For a nonresidential use at least 40% of that open space must sit between the front building line and the right-of-way, or 50% on a corner lot (Note 4). Where a side or rear yard abuts land in a MORE restricted district, that district's requirement applies instead (Note 3, § 143-22). Front setbacks increase on parcels fronting a user highway or inside a designated scenic area (Note 2, Article V). The lot minimum is the figure for a permitted one- or two-family dwelling and its accessory structures; other residential types and nonresidential uses take the standards in Article V or the special-permit standards at § 143-52 et seq.

Limited Development — Minimum lot width is 400 ft and minimum frontage 240 ft — separate columns, and the frontage is always the smaller. Every yard column prints two figures. The first is the principal structure and is the one recorded here; the second is the minimum setback for OFF-STREET PARKING and its accessways — 60 ft front, 50 ft side, 50 ft rear — which binds separately, and does not apply to a driveway serving a one- or two-family dwelling (Note 1).

Hamlet — The Hamlet District publishes TWO complete rows, one for Upper Red Hook and one for Annandale and Barrytown, and the base row here is Upper Red Hook. In ANNANDALE AND BARRYTOWN every figure is larger: 5 acres rather than 1.5, 300 ft of lot width and 200 ft of frontage rather than 180 and 135, a 75 ft front yard, 50 ft side and 50 ft rear, 5% coverage and 80% open space, with parking set back 50/25/25 ft. Which hamlet the parcel is in is a matter of location, so both rows are stated here rather than one being applied town-wide. In Annandale and Barrytown the front yard may be reduced to 25 ft where that matches the established setback on contiguous parcels on the same street (Note 6). In Upper Red Hook the front yard is instead 100 ft for parcels with frontage on the WEST side of Route 9 (Note 8). The side yard may be cut to zero for zero-lot-line residential development (Note 5). Minimum lot width is 180 ft and minimum frontage 135 ft — separate columns, and the frontage is always the smaller. Every yard column prints two figures. The first is the principal structure and is the one recorded here; the second is the minimum setback for OFF-STREET PARKING and its accessways — 25 ft front, 10 ft side, 15 ft rear — which binds separately, and does not apply to a driveway serving a one- or two-family dwelling (Note 1). A minimum of 70% of the lot must be open space. For a nonresidential use at least 40% of that open space must sit between the front building line and the right-of-way, or 50% on a corner lot (Note 4). Where a side or rear yard abuts land in a MORE restricted district, that district's requirement applies instead (Note 3, § 143-22). Front setbacks increase on parcels fronting a user highway or inside a designated scenic area (Note 2, Article V). The lot minimum is the figure for a permitted one- or two-family dwelling and its accessory structures; other residential types and nonresidential uses take the standards in Article V or the special-permit standards at § 143-52 et seq.

Institutional — A permitted residential dwelling in the I District does not take these standards: it follows the LD District if it sits west of NYS Route 9G and the RD3 District if it sits anywhere else in the town (the schedule's Institutional footnote). That split is geographic, so it is stated here rather than recorded as a condition. Residential uses in WC and I also carry the additional special permit criteria at § 143-53. Minimum lot width is 400 ft and minimum frontage 320 ft — separate columns, and the frontage is always the smaller. Every yard column prints two figures. The first is the principal structure and is the one recorded here; the second is the minimum setback for OFF-STREET PARKING and its accessways — 60 ft front, 25 ft side, 25 ft rear — which binds separately, and does not apply to a driveway serving a one- or two-family dwelling (Note 1). A minimum of 75% of the lot must be open space. For a nonresidential use at least 40% of that open space must sit between the front building line and the right-of-way, or 50% on a corner lot (Note 4). Where a side or rear yard abuts land in a MORE restricted district, that district's requirement applies instead (Note 3, § 143-22). Front setbacks increase on parcels fronting a user highway or inside a designated scenic area (Note 2, Article V). The lot minimum is the figure for a permitted one- or two-family dwelling and its accessory structures; other residential types and nonresidential uses take the standards in Article V or the special-permit standards at § 143-52 et seq.

Business 1 — A permitted residential dwelling here is governed by the R1 District standards instead of the district's own (the schedule's residential cross-reference footnote), and that cross-reference is recorded as a condition below. Minimum lot width is 150 ft and minimum frontage 120 ft — separate columns, and the frontage is always the smaller. Every yard column prints two figures. The first is the principal structure and is the one recorded here; the second is the minimum setback for OFF-STREET PARKING and its accessways — 40 ft front, 10 ft side, 25 ft rear — which binds separately, and does not apply to a driveway serving a one- or two-family dwelling (Note 1). A minimum of 40% of the lot must be open space. For a nonresidential use at least 40% of that open space must sit between the front building line and the right-of-way, or 50% on a corner lot (Note 4).

The lot minimum is the figure for a permitted one- or two-family dwelling and its accessory structures; other residential types and nonresidential uses take the standards in Article V or the special-permit standards at § 143-52 et seq.

Hamlet Business — Parking setbacks in HB are not on this schedule; they are set by § 143-49.3, which also carries the rest of the HB standards. The side yard is DOUBLED where the lot is adjacent to a residential district (Note 3). The front yard is 100 ft rather than 40 for parcels with frontage on the WEST side of Route 9 (Note 8). A permitted residential dwelling here is governed by the R1 District standards instead of the district's own (the schedule's residential cross-reference footnote), and that cross-reference is recorded as a condition below.

Agricultural Business District — The schedule gives AB no lot area, lot width or frontage, and § 143-39.1 adds none — it sets yards and coverage only. The setbacks recorded here are the NONRESIDENTIAL ones. A new principal RESIDENTIAL building needs only 10 ft from any property boundary, and an accessory structure 3 ft, which is recorded as a condition. Off-street parking and accessways are set back 25 ft at the front and 60 ft at the side and rear. The 7% coverage applies to uses not in a farmstead complex or building envelope. Unenclosed manure storage must be 100 ft from any lot line, wetland, stream, water body or potable well. A minimum of 80% of the lot must be open space. For a nonresidential use at least 40% of that open space must sit between the front building line and the right-of-way, or 50% on a corner lot (Note 4).

Traditional Neighborhood Development District — The schedule publishes no figure of any kind for TND — every column sends you to § 143-49.1. The district is form-based and is divided into three mapped subdistricts, Commercial Center, Residential Neighborhood and Office-Industrial, each with its own standards, so there is no single row to record and none is guessed here. Two features of those standards have no column of their own and are worth stating: the front setback is a build-to RANGE with a maximum of 18 ft in both the Residential Neighborhood and the Commercial Center subdistricts, so a building may not be set further back; and the Commercial Center caps lot frontage at a maximum as well as a minimum. Read § 143-49.1 subsections I through Q for the subdistrict this parcel is in.
