Annexation - As introduced, requires a municipality to obtain approval of a proposed annexation from the county legislative body; requires the municipality to submit certain reports to the county legislative body regarding the proposed annexation. - Amends TCA Title 6, Chapter 51, Part 1.

HB 2419 requires municipalities to obtain county legislative body approval before annexing land, mandating they submit a financial impact study (covering infrastructure, schools, and county costs) and a statement proving service capacity (water, roads, police, etc.). Counties must review these documents within 60 days and vote on approval; if they fail to act within 90 days, the annexation is automatically denied. The bill excludes single, contiguous lots of five acres or less from these requirements. It aims to ensure counties can assess fiscal impacts before annexations occur, protecting county taxpayers and services.
