Perth Amboy, NJ Building Setbacks & Zoning: Lot Coverage Limits (2026)

Lot coverage in Perth Amboy City Code Chapter 430 is set use by use in the conditional-use standards of § 430-58(E). For high-rise multifamily residential development, subsection (3) fixes maximum permitted building lot coverage at twenty percent and maximum permitted impervious lot coverage at fifty percent. For two-family dwellings in zones that permit them as a conditional use, subsection (11) fixes maximum lot coverage by building at thirty-five percent and maximum impervious coverage at forty-five percent. The coverage column for ordinary residential and commercial districts belongs to the Bulk Schedule attachment that § 430-9 refers to, and the code text does not print it.

Two definitions decide what counts. Under the definition of accessory use or structure in § 430-5, the area occupied by an accessory building is computed into the building area, and the total area of the accessory buildings and the main building shall not exceed the permitted building area. A shed or detached garage therefore uses up the same building coverage allowance as the house.

The conditional-use path adds review. Under § 430-58(B), an application goes to the approving board, which holds a public hearing and must decide within ninety-five days of a complete application, or within any further time the applicant consents to. Every conditional use except local municipal schools needs site plan review and approval, and the burden of proof rests on the applicant. Where the board approves, the owner has three years to secure a building permit, with one extension of up to one year for good cause, or the approval is null and void.
