Parsippany-Troy Hills, NJ Building Setbacks & Zoning: Lot Coverage Limits (2026)

The percentage caps for most zones are not in the running text of Chapter 430. Section 430-35 adopts the Schedule of Area, Yard and Building Requirements as part of the chapter, and § 430-36 says the schedule summarizes the regulations by zoning district, including lot size, yards and building heights. The provisions that print coverage numbers directly are these.

Section 430-13B(5), added 10-23-2007 by Ord. No. 2007:48, lets accessory storage sheds in all residential districts, excluding sheds for registered motor vehicles, cover an additional 100 square feet over and above the maximum building coverage permitted in the district. Section 430-10I lets wooden decks attached to a principal dwelling cover no more than an additional four percent of the lot over and above what is otherwise permitted in the district. Section 430-10K provides that a wheelchair-accessible ramp or lift in a front yard is not considered impervious coverage.

A place of worship approved as a conditional use under § 430-41C(1) is held to maximum building coverage of 35% and maximum impervious coverage of 65%, with a maximum building height of two stories and 35 feet. In the Route 46 Corridor Redevelopment Area, § 430-311 sets maximum building coverage at 35% and maximum impervious coverage at 90% on a minimum lot area of 2 acres. Assisted living facilities in the COD Corporate Office District are held to 25% building coverage and 60% impervious coverage under § 430-236E.

Coverage also limits rebuilding. Under § 430-33A a nonconforming structure destroyed to an extent greater than 50% of its assessed value can be replaced only if the height, FAR, coverage and yard setbacks are not expanded or further infringed upon, and the application goes to the Planning Board. A zoning permit signed by the Administrative Officer is required under § 430-295 before a building or structure is erected.
