Annexation - As introduced, authorizes municipalities to annex territory outside of their urban growth boundaries so long as the territory is not within another municipality's urban growth boundary. - Amends TCA Title 6, Chapter 51 and Title 6, Chapter 58.

SB 2600 (Tennessee) changes annexation rules by allowing municipalities to annex land outside their current urban growth boundaries, provided the land isn't already within another municipality's boundary. This directly affects local governments and property owners in areas targeted for annexation, removing a prior requirement that annexed territory must be entirely within the municipality's growth boundary. Key provisions amend Tennessee Code sections 6-51-104, 6-51-120, and add new language to 6-58-111, streamlining the process for annexing land in a county's planned growth or rural areas without needing to update a growth plan. The bill takes effect upon becoming law.
