Mount Vernon, NY Parking Rules: Driveway Rules (2026)

Under § 267-42A(1)(a), an access driveway serving a one- or two-family residence must be at least nine feet wide, stay at least three feet from any side or rear lot line, and tie into the street with a curb radius return of not less than 25 percent of the driveway's width. Grade is capped at 10 percent, though the Planning Board may allow up to 12 percent for a single-family driveway if it finds the steeper grade reduces environmental impact. Only one curb cut is permitted per one- or two-family residence, except a circular driveway may have two curb cuts on a lot with 150 feet or more of road frontage, and no curb cut may sit inside the sight-visibility triangle required at street intersections under Article IV.

Separately, § 267-43A requires every off-street parking facility, including driveways, to be surfaced in asphaltic cement concrete, portland cement concrete, paving stone, or brick, so an unpaved gravel or dirt driveway does not meet the code. The Building Commissioner enforces Chapter 267 under § 267-51, and no building permit may issue for driveway work that violates these standards absent a variance from the Zoning Board of Appeals under Article IX.
