Trenton, NJ zoning map & districts

As New Jersey's capital, Trenton carries a substantial share of state-government and institutional land use around the State House complex, which shapes downtown development differently than in a typical city of its size. Trenton's zoning is set by the City of Trenton Zoning Ordinance, administered by the Division of Planning under New Jersey's Municipal Land Use Law, with a Planning Board and Zoning Board of Adjustment.

How zoning works in Trenton

The city faces active redevelopment and affordable-housing pressure tied to New Jersey's Mount Laurel doctrine and Fair Housing Act framework, and downtown Trenton in particular has been a focus of state and city revitalization efforts aimed at converting underused office and institutional-adjacent parcels to residential and mixed-use development.
