New Hampshire Housing periodically updates the Technical Design and Construction Standards for Rehabilitation to ensure a basis for providing safe, sanitary, cost effective and energy efficient housing for all occupants. These standards apply to newly acquired or refinanced projects with a limited scope of work. Requirements covered by the standards include capital needs assessments, environmental mitigation, life safety and other areas.

Below is a summary of the significant changes to NH Housing’s Technical Design and Construction Standards for Rehabilitation. The updated rehabilitation standards go into effect for applications received on or after May 9, 2022.

  • Lead and copper levels in drinking water have been revised (Reference D.2.).
