Summary

Amends federal rural housing financing law to explicitly allow accessory dwelling units (ADUs) as eligible appurtenances and to expand the definition of "rural areas" by raising the population threshold from 2,500 to 10,000. The changes broaden which housing features can be financed and increase the number of towns and small cities that qualify for rural housing financing authorities, affecting borrowers, lenders, and local planning decisions in more communities.

• Explicitly authorizes accessory dwelling units (ADUs) as eligible appurtenances for rural housing financing.
• Raises the population threshold defining "rural areas" from 2,500 to 10,000 residents for the cited provision.
• Expands the geographic scope of federal rural housing financing eligibility to include more towns and small cities.
• Does not appropriate new funds or change tax law; it modifies eligibility and allowable financed property features.
• Implementation requires federal program administrators and lenders to update guidance and underwriting practices.
• May increase opportunities for homeowners to add ADUs that can be financed through rural housing programs.
• Local zoning and permitting rules still control whether ADUs can actually be built, so federal financing is necessary but not sufficient.
• Broad but narrowly focused change: adjusts two statutory definitions/allowances rather than creating new programs.
