relative to accessory dwelling unit uses allowed by right.

This bill requires New Hampshire municipalities to allow homeowners to build one accessory dwelling unit, such as a garage conversion or an addition, on their single-family property without needing special approval. It defines these units as separate living spaces with their own kitchen and bathroom and sets minimum size limits of 1,000 square feet for at least one unit. While towns can still require owner occupancy and enforce parking or aesthetic rules, they cannot mandate familial relationships between residents or restrict units to a single bedroom. Additionally, the legislation clarifies that municipalities must permit the conversion of existing structures like detached garages into these units even if they do not currently meet setback or lot coverage standards.
