Fannie Mae has recently expanded financing options for accessory dwelling units (ADUs), significantly enhancing potential income for landlords and homeowners. This initiative aims to facilitate property owners in adding rentable units, thus increasing cash flow and property appreciation.
In its latest announcement, Fannie Mae stated it is broadening ADU eligibility as part of efforts to address the increasing demand for affordable housing. The update, found in the Selling Guide Announcement SEL-2025-10, now allows for properties to include up to four units, including the primary dwelling and three ADUs, provided they meet local zoning regulations. This change also permits ADUs on single-wide manufactured homes, accommodating rural and low-density areas.
Moreover, improvements have been made to financing energy and climate-resilient enhancements, allowing homeowners to safeguard their ADUs while making them appealing to potential renters. Importantly, Fannie Mae has integrated FHA loan guidelines into its new ADU rules, making it easier for borrowers to finance properties with existing or planned ADUs.
However, challenges remain, particularly in appraisals as these configurations are still emerging in the market. Regulatory environments also pose challenges, with some areas facing strict zoning laws that can hinder the establishment of ADUs.
While the new guidelines offer opportunities for homeowners and investors to expand their portfolios and address the housing crisis, they also come with financial considerations, as building an ADU can be costly, averaging between $60,000 to $285,000 based on various factors.
