This legislation, the Native American Housing Assistance and Self-Determination Modernization Act of 2026, reauthorizes the foundational Native American Housing Assistance and Self-Determination Act of 1996 (NAHASDA) for fiscal years 2027 through 2033. Its primary goal is to modernize and improve housing assistance programs for Native American and Native Hawaiian communities, fostering greater self-determination and flexibility in addressing their unique housing needs. The bill introduces significant streamlining measures, particularly concerning environmental review requirements. It consolidates environmental reviews for projects using multiple federal funding sources and exempts certain activities, such as small-scale affordable housing or rehabilitation, from review. Furthermore, it grants Indian tribes and the Department of Hawaiian Home Lands (DHHL) greater flexibility in technical assistance and allows them to adopt their own procurement policies for goods and services. Reporting requirements are also streamlined, permitting consolidated annual performance reports for multiple grants. Eligibility for housing assistance is expanded under the bill. It allows recipients to provide homeownership assistance to families with incomes up to 120% of the area median income, with a limit on the percentage of annual grant funds used for such families. The bill also clarifies rent rules for units owned or operated by tribes and includes college housing assistance as an eligible activity. A notable change is the extension of leasehold interests on trust or restricted lands for housing purposes from 50 years to 99 years. Addressing homelessness is a significant focus, with the establishment of a new Tribal HUD-VASH program for homeless or at-risk Indian veterans, allocating 5% of rental assistance funds. Two pilot programs are created to provide housing assistance for homeless Native Americans, Alaska Natives, and Native Hawaiians, prioritizing vulnerable populations like youth, families with children, and survivors of domestic violence. Additionally, the bill authorizes a Tribal and Rural Continuum of Care Builds Program to provide competitive grants for the construction, acquisition, or rehabilitation of permanent supportive housing. The legislation also modernizes the Section 184 Indian Home Loan Guarantee program and the Section 184A Loan Guarantees for Native Hawaiian Housing , expanding eligible lenders and allowing for direct guarantee endorsement processes. It exempts tribal entities from certain housing counseling certification requirements and the Build America, Buy America requirements for HUD-administered programs. Finally, the bill mandates the establishment of a HUD Tribal Intergovernmental Advisory Committee to provide policy recommendations and address housing supply chain challenges in Tribal and Native Hawaiian communities.
