Single Family Housing Guaranteed Loan Program: Income-Producing Accessory Dwelling Unit (ADU) Provisions
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The USDA's Rural Housing Service (RHS) is proposing amendments to the Single Family Housing Guaranteed Loan Program (SFHGLP) to allow borrowers to finance single-family homes that include one or more income-producing Accessory Dwelling Units (ADUs). Currently, the program does not explicitly permit financing of properties where ADUs generate rental or other income, and this proposed rule would remove that barrier for rural homebuyers. Under the proposed changes, borrowers could use SFHGLP-backed loans to purchase or refinance properties with ADUs — such as a guest house, basement apartment, or detached cottage — that are rented out or otherwise generate income. This is designed to help rural households offset mortgage costs through rental income while increasing housing supply in eligible rural areas. The proposal also clarifies that properties with features supporting home-based business operations (such as a workshop, studio, or office space) can be financed, as long as the property does not have commercial real estate characteristics. This distinction protects the residential nature of the loan guarantee while accommodating the growing trend of remote and home-based work. This is a proposed rule open for public comment via Regulations.gov. Final implementation details, income calculation methodology for ADU rental income, and any loan-to-value adjustments will be determined after the comment period closes.
