Providence, RI zoning map & districts

Providence's zoning ordinance was comprehensively rewritten and adopted in November 2014, replacing an older Euclidean-style code with a hybrid system: conventional use-based residential and industrial districts outside downtown, paired with more prescriptive, building-form-oriented standards in the core. The Department of Planning and Development staffs day-to-day zoning administration and site plan review; the Zoning Board of Review hears variances and special-use permits, and the City Plan Commission handles subdivisions, planned developments, and master plan approvals.

The code Providence Zoning Ordinance

Providence zoning map

Providence's official zoning map and the full ordinance text are maintained by the Department of Planning and Development and published through the city's GIS-based zoning map; the City Clerk's Code of Ordinances hosts the codified text of Chapter 27.

There is no link to the official map here yet — confirm current district boundaries directly with the Providence planning or zoning department.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.
