City of East Providence adopts new accessory dwelling unit ordinance - by Roberto DaSilva

The East Providence City Council unanimously approved new zoning modifications on September 2, 2025, to comply with Rhode Island state housing legislation aimed at increasing residential construction opportunities.

The most significant change allows accessory dwelling units (ADUs) throughout the city, which are secondary housing units that can be built within existing homes, attached to primary residences, or constructed as separate structures like converted garages or standalone cottages.

While Rhode Island state law permits detached ADUs on lots of 20,000 square feet or larger, East Providence went beyond minimum requirements by allowing detached units on lots as small as 5,000 square feet.

This decision significantly expands opportunities for homeowners in the densely populated community to add rental units to their properties.

The new regulations mirror trends seen across California, where ADU laws have been progressively liberalized to address housing shortages.

California property owners have benefited from similar reduced lot size requirements and streamlined approval processes for ADUs, which provide additional rental income while creating affordable housing options.

The East Providence approach demonstrates how other states are adopting California-style ADU policies to tackle housing affordability challenges, suggesting continued momentum for accessory dwelling unit expansion nationwide.
