The purpose of this legislation is to simplify and speed up the review process for certain housing-related activities under the National Environmental Policy Act (NEPA). The goal is to make it easier to develop housing, especially affordable housing, by reducing the regulatory burden and streamlining the approval process. Key provisions of the legislation require the Secretary of Housing and Urban Development to reclassify various housing-related activities. This includes expanding the types of activities that can be exempt from extensive environmental reviews.
