The bill amends several sections of the Rhode Island zoning enabling act of 1991, enhancing the framework for zoning regulations with the intent of preserving neighborhood character and promoting smart growth. Key provisions include:

- Emphasizing the right to housing for every Rhode Islander, regardless of income.
- Promoting smart growth, redevelopment of previously developed land, and preservation of undeveloped land.
- Requiring municipalities to consider public and civic spaces, transportation, and public facilities in their zoning plans.
- Introducing definitions for terms related to zoning, including "architectural form," "civic space," and "redevelopment."
- Establishing inclusionary zoning requirements, mandating that developments include affordable housing units, which must remain affordable for a minimum of 30 years. Various methods to meet this requirement are allowed, including on-site construction or payment of a fee in lieu.
- Clarifying the treatment of nonconforming uses and establishing provisions for the alteration of nonconforming developments.
- Introducing zoning incentives for developments that preserve open space.
- Mandating efficient review of development and redevelopment proposals.

The act takes effect upon passage.
