Tennessee Housing Development Agency - As enacted, increases, from $4 billion to $5 billion, the maximum aggregate principal amount for which the agency may issue bonds and notes at any one time. - Amends TCA Section 13-23-121.

HB 331 amends Tennessee Code Annotated Section 13-23-121 to increase the Tennessee Housing Development Agency's (THDA) maximum bond issuance limit from $4 billion to $6 billion. This change directly enables THDA to issue more bonds for financing affordable housing loans, primarily benefiting low- and moderate-income Tennessee residents seeking below-market interest rate mortgages. The bill's key provision adjusts the statutory cap to address growing demand for these housing programs, which THDA has managed within the previous limit since 2008. The increase took effect on May 2, 2025, after receiving legislative and gubernatorial approval.
