Hamlet District — Lot frontage and lot width at the building line are DIFFERENT: 100 ft of frontage but 150 ft of width at the building line, so a lot that fronts the road adequately can still be too narrow where the house goes.

Town Center District — TC publishes NO minimum lot area for a residential lot — the schedule sends you to Note A, which states there is none, and sets the residential density instead at one dwelling unit per half acre before any approved density bonus. A COMMERCIAL lot in TC does have a minimum, of two acres, and a commercial building footprint is capped at 2,500 sq ft, raised to 4,000 sq ft for food and grocery store uses (Note 7). The front setback is a RANGE, not a minimum: 20 ft minimum and 35 ft MAXIMUM, so a building may not be set further back than 35 ft. The 25 ft side yard, and the 20 ft parking side setback, may be cut to ZERO for zero-lot-line development authorised by special use permit where emergency vehicle access is adequate (Note 3) — the trigger is that kind of development rather than the permit alone, so it is stated here rather than as a separate set of standards that any application reaching the Planning Board would qualify for. Residential development fronting Route 55 must devote at least 15% of total building square footage to commercial uses, and the last 25% of dwelling units get no certificate of occupancy until that commercial component is complete (Note 5). Commercial, multifamily, townhouse and mixed-use development must also meet the TC Design Standards at § 210 Attachment 3 (Note 6). Lot frontage and lot width at the building line are both 75 ft. Parking areas and access driveways have a complete second set of setbacks, separate from the building setbacks above: 20 ft front, 20 ft side, 30 ft rear. Parking is barred from any front yard setback and must go to the rear or side of the principal building, with landscaping and screening under § 210-25B (Note 4). A minimum of 50% of the lot must be left as open space, which is a separate test from the coverage cap. These standards apply to permitted uses; Article VI may set extraordinary standards for special permit uses (Note 1). They are not controlling on municipal uses on municipal property (Note 2). Coverage is BUILDING coverage — the composite footprint of all principal and accessory structures, excluding uncovered porches, terraces and steps.

Airport District — Lot frontage and lot width at the building line are DIFFERENT: 100 ft of frontage but 200 ft of width at the building line, so a lot that fronts the road adequately can still be too narrow where the house goes. Parking areas and access driveways have a complete second set of setbacks, separate from the building setbacks above: 35 ft front, 15 ft side, 20 ft rear. Parking is barred from any front yard setback and must go to the rear or side of the principal building, with landscaping and screening under § 210-25B (Note 4).

Short-term rentals

Short-term rentals allowed with local rules. Short-term rental is a defined and regulated use. § 210-85A of Zoning Chapter 210 defines SHORT TERM RENTAL as 'an accessory use or supplementary business in a dwelling unit' letting it for less than 30 days, and ACCESSORY USE is separately defined as customarily incidental and subordinate to the principal use on the same lot. 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 Union Vale at (845) 724-5600 before listing.
