Expanding Housing Supply by Building Accessory Dwelling Units

A new guide and a new digital tool detail ways to ease New Hampshire’s housing crisis

Nhbr Advertiser Webinar Logo

New Hampshire’s housing crisis is impacting its people, communities and businesses. The state’s current housing shortage is over 23,500 units, and it’s estimated that nearly 90,000 units will be needed between 2020 and 2040.

Accessory dwelling units (ADUs) are a proven way to expand the supply of affordable housing without further land development. Policy and Program Models for Creating Accessory Dwelling Units in New Hampshire, a new guide written by Southern New Hampshire Planning Commission on behalf of New Hampshire Housing, presents examples of policy and program models along with tools and techniques that will support ADU production.

In this webinar we’ll hear from the report’s lead author, James Vayo, and Ben Frost, deputy executive director of New Hampshire Housing, on how building ADUs in communities around the state can expand the state’s housing supply and help meet the need for different types of housing units.

Additionally, Max Latona, director of the New Hampshire Zoning Atlas project, will explain how this new digital tool makes available all of New Hampshire’s municipal zoning regulations, and will help policymakers, citizens and developers understand how zoning impacts housing supply and affordability.

Thank you for attending this webinar on Thursday, May 11, 2023 from 11 a.m. to 12 p.m.

Unfortunately, due to unforeseen circumstances and technical difficulties, there is no recording of the live presentation. We are looking to re-record as soon as possible. In the meantime, please feel free to download James Vayo’s slides presentation from the event.
