Kol’s week-long ADU roadshow for New Hampshire Housing was a success, helping launch important dialogue about the value of  ADUs for homeowners as well as the possibilities they offer to expand the availability of affordable housing in NH. His community presentations around the state as well as at a conference spotlighted his depth of knowledge about and passion for ADUs, and his willingness to engage in discussion on the issues involved

Kol-Peterson-FB-Cover-image_PortsmouthKol’s presentation told a compelling story about how and where ADUs fit into the greater housing affordability picture. After Kol’s presentation, local leaders in New Hampshire and Maine left equipped with the information they need to create sound policy as they write local ADU ordinances and craft and amend statewide laws. Homeowners left feeling empowered and inspired to take control of their own financial situations and use their home to generate an income.
