Summary

This bill amends the National Housing Act to create a new program for the Federal Housing Administration (FHA) to insure second mortgages used to build accessory dwelling units (ADUs), such as backyard cottages or basement apartments, on single-family properties. It also requires Fannie Mae and Freddie Mac to be allowed to buy and package these insured loans into securities.

Sec. 2, Insurance for ADU construction loans: Within two years, the Department of Housing and Urban Development must start a program to insure second liens for building ADUs. The loan amount is capped at the lesser of 30% of the standard FHA loan limit for a one-unit home, or 100% of the property's projected value after construction minus any existing loans. The Secretary can increase this cap based on half of the expected annual rental income from the ADU. Borrowers must apply and certify they own the property. The annual insurance premium cannot exceed 1% of the insured principal. The Secretary must report annually to Congress on the program and can issue rules. An ADU is defined as a modular, manufactured, or converted unit with kitchen, sleeping, and bathroom facilities, added to, inside, or detached from a single-family home on one property.

Sec. 3, Purchase and securitization of insured loans: The Director of the Federal Housing Finance Agency must allow Fannie Mae and Freddie Mac to buy and securitize these insured loans. The Director can only prohibit this if market conditions pose an excessive and unavoidable risk, and after notifying Congress in writing. The Director must include information on these purchases and securitizations in their annual report to Congress.
