Clarkstown, NY Building Setbacks & Zoning: Structure Height Limits (2026)

Chapter 290, Zoning, sets the Town of Clarkstown's building-height standards in § 290-20, Additional bulk regulations. For the Multifamily Residential Districts, MF-1, MF-2 and MF-3, § 290-20F(5) fixes an absolute ceiling: no building may rise higher than three stories or 35 feet, applying whichever limit is smaller, on top of a sliding formula allowing nine inches of height for every foot a wall sits back from the lot line. That formula lets a building close to a boundary stay lower while permitting more height toward the interior of a large parcel, but the three-story/35-foot cap always controls in the MF Districts.

The same section links height to spacing. § 290-20E(1) bars any principal residential building from sitting closer to another principal building on the same lot than the height of the taller of the two, with a hard 30-foot floor regardless of height. Detached accessory buildings must clear the principal structure by their own height and never less than 15 feet, except that accessory buildings in MF Districts may abut the principal building if not detached.

Height tied to front-yard depth is measured from a designated street line set back from the street centerline (40 feet on Major streets, 30 feet on Secondary streets, 25 feet on Local streets) rather than from the property line itself.

The Town's low-density single-family districts (R-80, R-40, R-22, R-15, R-10) use the same Bulk Table structure referenced in § 290-11, but their specific height figures are published in a separate Bulk Table attachment to Chapter 290 rather than in the chapter text itself; owners in those districts should pull the current attachment from the Building Department or eCode360 rather than relying on the MF figures above, which apply only to the Multifamily Districts.
