Wayne, NJ Building Setbacks & Zoning: Structure Height Limits (2026)

Wayne Township Code § 134-32.2 F sets the maximum building height in the R-45 very low density residential district at 35 feet and 2 1/2 stories as measured from the average finished grade. The code then fixes where the measuring happens: the measurement shall be taken at the centerline of the length of the building on all 4 sides. The reference point is the average finished grade, not the grade at one corner or at the front door.

Accessory structures have their own ceiling in § 134-32.2 E(3). Height there is 15 feet maximum to the top of the ridge of a pitched roof, measured from the finished floor, or 12 feet to the top of a flat roof measured from the finished floor. Paragraph E(4) adds that accessory buildings, structures and uses must also comply with § 134-62, which separately caps how many accessory structures a single-family property can hold.

Height is only one of the R-45 bulk limits that work together. Section 134-32.2 G caps floor area ratio at 0.22 on standard lots, subsection H caps impervious coverage at 40%, and subsection D fixes the yards. A taller building has to fit inside all of them, so a second story does not buy additional floor area beyond the ratio.

Other districts print their own heights. In the Residential B Cluster district, § 134-36.2 B(1)(a) limits all dwellings to 2 1/2 stories or 35 feet, and § 134-36.3(6) adds that no portion of any structure can be closer to the front property line than the height of that structure at any particular point. Sheds in that district are limited to seven feet in height under § 134-36.1 F.

The Zoning Officer enforces the chapter, and § 134-26.3 B(1)(e) requires a zoning permit, showing whether the request meets Chapter 134, before a building permit issues.
