Summary

Piscataway Township Code Section 21-807 caps building height in the LI-1 and M-1 Industrial Zones at three stories and 40 feet for a principal building, and one and a half stories and 25 feet for an accessory building. The limit applies under the Section 21-8 schedule for any permitted use or accessory use on an LI-1 or M-1 parcel of three acres or larger.

§ 21-8. DEVELOPMENT IN LI-1 AND M-1 INDUSTRIAL ZONES. The development in the LI-1 and M-1 Industrial Zones of any permitted use or permitted accessory use on a parcel of land which is three acres or larger is forthwith subject to and to be in strict accordance with the following schedule of bulk and density requirements: § 21-80 ... ... 7. Maximum Heights. Principal building — three stories, 40 feet; Accessory building — 1 1/2 stories, 25 feet.

Full Breakdown

Section 21-8 of the Zoning Chapter creates a dedicated bulk and density schedule for large industrial development: the development in the LI-1 and M-1 Industrial Zones of any permitted use or permitted accessory use on a parcel of land which is three acres or larger is subject to the following schedule of bulk and density requirements. Section 21-807 sets the height ceiling within that schedule at three stories and 40 feet for the principal building and one and a half stories and 25 feet for any accessory building, immediately after Section 21-805's 45 percent maximum building coverage and Section 21-806's 15,000-square-foot minimum first-floor area.

The three-story, 40-foot cap sits below the taller limits the Township allows in some mixed-use and redevelopment districts elsewhere in Chapter 21, reflecting that this schedule targets standalone industrial buildings on large parcels rather than dense multi-story development. Because the cap is keyed to the three-acre threshold in Section 21-8, a smaller LI-1 or M-1 lot, or a parcel in a different zone, falls under the Township's separate Schedule of General Requirements at Section 21-501.1 instead of this height limit.

Violations & Fines

A building plan showing a principal structure above 40 feet or three stories, or an accessory building above 25 feet or one and a half stories, on a qualifying LI-1 or M-1 parcel violates Section 21-807 and cannot obtain site plan or building permit approval until the design is lowered or a height variance is granted by the Zoning Board of Adjustment.

Frequently Asked Questions

How tall can a warehouse or industrial building be built in Piscataway?
On an LI-1 or M-1 parcel of three acres or larger, Section 21-807 caps the principal building at three stories and 40 feet, with accessory buildings limited to one and a half stories and 25 feet, as part of the Section 21-8 bulk and density schedule for large industrial development.
Does this 40-foot height limit apply to every industrial lot in Piscataway?
No. Section 21-8 ties the schedule, including the Section 21-807 height cap, to LI-1 and M-1 parcels of three acres or larger. Smaller industrial lots and other zoning districts are instead governed by the Township's separate Schedule of General Requirements at Section 21-501.1.
What happens if a proposed building exceeds the height cap?
The Planning Board cannot approve a site plan that shows a principal building over 40 feet or three stories, or an accessory building over 25 feet or one and a half stories, on a qualifying parcel unless the applicant obtains a height variance from the Zoning Board of Adjustment first.
