Bill Summary · HB 1012

Legislative bill overview

HB 1012 seeks to repeal New Hampshire's allowances for accessory dwelling units (ADUs) and detached accessory dwelling units (DADUs)—smaller residential structures on single-family properties that can serve as rental units or housing for family members. The bill would eliminate state-level authorization for these housing types, potentially restricting local municipalities' ability to permit them.

Why is this important

ADUs and DADUs have become increasingly important tools for addressing housing affordability and supply shortages in many states. Their repeal could limit housing options for renters, young families, and aging residents, while also reducing potential rental income for property owners and limiting municipalities' flexibility in addressing local housing needs.

Potential points of contention

  • Housing supply impact: Removing ADU allowances reduces available housing units and may exacerbate affordability challenges in a tight market
  • Local control vs. state restriction: The bill limits local governments' authority to permit ADUs, even if communities want them to address housing demand
  • Property owner flexibility: Homeowners lose the option to create additional income-generating or multi-generational housing on their own property
  • Economic development: Restricting housing types may discourage young professionals from relocating to New Hampshire or aging residents from remaining in their communities
