Parsippany-Troy Hills, NJ Building Setbacks & Zoning: Setback Rules (2026)

Section 430-10 of Chapter 430 controls how yards are measured and what can project into them. No yard required for one building can be counted toward another, and no existing yard or lot can be reduced below the minimum, under § 430-10A and B. Sheds permitted as an accessory use to a residential dwelling must be no closer than six feet to the side or rear lot line. Cornices and eaves can project up to two feet over any required yard or court. Sills, leaders, belt courses and similar ornamental or structural features can project only six inches, and an open fire balcony, fire escape or fire tower can project into a required yard not more than four feet. Ground story and bay windows or balconies can project not more than three feet into a required rear yard or a side yard over six feet wide. An open porch or entranceway not higher than the first story can project into a required front yard not more than eight feet, and a chimney, smokestack, flue or elevator shaft not more than three feet.

Wooden decks attached to a principal dwelling are permitted in residential districts if they do not encroach into the side or rear yard more than 50% of the minimum side or rear yard requirement for principal buildings. A deck can never extend closer than the minimum accessory structure setback or six feet, whichever is greater.

Section 430-13 controls accessory buildings: none goes in a required yard except as specified, none goes in the required front yard of a corner lot, and the side-yard exception keeps them six feet from the main building. Section 430-50E(9) sets a 15-foot rear and side setback for a detached affordable accessory apartment, and § 430-29.1D(1) requires a temporary storage unit to sit at least five feet from the property line.

Some districts print their yards in the text. A place of worship under § 430-41C(1) needs a 50-foot front yard and 35-foot side and rear yards. The Route 46 Corridor in § 430-311 sets 25 feet front, 10 feet side and 15 feet rear, and § 430-236E sets 50, 25 and 35 feet for assisted living in the COD district.
