Freehold Township, NJ Accessory Structures: ADU Rules (2026)

Freehold Township's Land Use Chapter treats an accessory apartment as a conditional use rather than a right that comes automatically with owning a single-family lot. Section 190-219, written for the chapter's Affordable Housing article, defines ACCESSORY APARTMENT as 'a self-contained residential dwelling unit with a kitchen, sanitary facilities, sleeping quarters and a private entrance,' which can be created inside an existing home, by converting an existing accessory structure on the same site, through an addition to an existing home or accessory building, or by building an entirely new accessory structure on the lot.

That use is only listed as available, and only as a conditional use requiring a conditional use permit from the Planning Board, in two zones: the Rural-Environmental (R-E) Zone under § 190-126C(5), and the Residential R-80 Zone under § 190-129C(2). Both zone sections send the applicant to Chapter 190's Article XIX conditional use standards and to the missing Schedule C bulk table for the dimensional requirements that would apply to the resulting unit. 17, which was deleted when the Land Use Chapter was recodified in 2005, leaving the definition and the conditional-use listing as the operative text rather than a dedicated set of size or parking standards.
