The main purpose of the Advancing Better Options for Dwellings Everywhere Act, also known as the ABODE Act, is to improve access to affordable housing by directing the Secretary of Housing and Urban Development to run a grant competition. This competition is designed to encourage the development and rehabilitation of single- and multi-family homes, particularly for low-income households. Key provisions of the ABODE Act include the establishment of a grant competition that targets academic organizations, nonprofit groups, and mission-driven developers.
