Regional Authorities and Special Districts - As enacted, revises various provisions of the Real Estate Infrastructure Development Act of 2025. - Amends TCA Title 7; Title 9; Title 12; Title 13; Title 66; Title 67 and Title 68.

HB 1681 revises Tennessee's infrastructure development district laws to clarify procedures for creating and managing these districts, which are used for real estate infrastructure projects in local communities. Key changes include requiring public hearings for district establishment, allowing joint hearings across multiple municipalities, limiting infrastructure bonds to 30 years (with phase-based extensions), and permitting special assessments to cover administrative costs like property tax collection. The bill also adjusts district dissolution to occur 30 years after the last special assessment is levied, rather than from the district's creation date. These provisions directly affect municipalities establishing such districts and property owners within them who may face special assessments.
