South Kingstown Zoning Overview

South Kingstown is a town of approximately 31,757 residents in Washington County, Rhode Island. The town manages land use and development through its local zoning ordinance, which divides the municipality into districts regulating permitted uses, building heights, lot sizes, setbacks, and density.

South Kingstown's zoning code includes a wide range of residential districts from very low-density rural areas (R-200 at approximately 5 acres) through R-80, R-40, and R-20 (20,000 sq ft minimum). The R-20 district has setbacks of 25 feet (front), 10 feet (side), and 20 feet (rear). The town also has a Village Residential (VR) district, a Commercial (C) district, and an Industrial (I) district.

ADU Rules

  1. Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
