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

The R-25 Residential 25 Zone was added on 5-6-2025 by Ord. No. 25-15 to permit medium-density single-family subdivisions in Howell Township. Section 188-73.1(E) prints a minimum lot area of 8,000 square feet, minimum lot frontage of 50 feet, a maximum principal building height of 30 feet and a maximum of 2.5 stories.

Other zones print their own caps. Residential lots subdivided under the farmland preservation option of § 188-69(D)(6)(d) carry Maximum height: 30 feet/2 1/2 stories, and the ARE-2 section, § 188-69.1, prints Maximum height: 30 feet for the same kind of lot. In the R-5 age-restricted zone, § 188-73(E) sets a maximum building height of 45 feet and 2 1/2 stories. The R-3 patio and zero lot line site under § 188-70(C) is held to a maximum building height of 30 feet.

Accessory structures sit lower. Under § 188-11(A)(1)(g), an open-air rear overhang cannot exceed 14 feet to the peak or the height of the principal structure, whichever is less. A shed that qualifies for the zero foot setback must be eight feet in height or less. A pool cabana under § 188-11(D)(7) tops out at one story or 20 feet to the peak, one story or 14 feet on lots less than 40,000 square feet, and one story or 12 feet with a flat roof.

Items above the cap: § 188-13(A) lets mechanical equipment, chimneys and the structures enclosing them rise above the maximum height in any district, but the setback from the nearest property line must equal the structure's own height. Under § 188-13(B)(1), a private radio or television antenna in a residential zone sits no nearer to the lot line than its total height, and a rooftop antenna cannot exceed 12 feet. Personal earth terminals cannot exceed 12 feet.
