RSA 674:80: Amendment to Zoning Regulations.

I. Notwithstanding any provision to the contrary, municipalities shall allow multi-family residential development on commercially zoned land, provided that adequate infrastructure, including roads, water, and sewage systems, shall be available or provided to support the development.

II. Nothing in this section shall be interpreted to prohibit municipalities from restricting residential development in zones where industrial and manufacturing uses are permitted which may result in impacts that are incompatible with residential use, such as air, noise, odor, or transportation impacts.

III. A municipality may require all available ground floor space or a percentage thereof to be dedicated to retail or similar uses.

IV. A municipality shall provide an exemption to any requirements regarding setbacks, height, or frontage of a building being converted to multi-family or mixed-use through adaptive reuse, provided that the building's floor area, height, and setbacks do not change.
