Amends GS 160D-202 (Municipal extraterritorial jurisdiction) by creating new subsection (a1) that prevents cities from exercising extraterritorial authority in counties that have adopted a zoning or unified development ordinance. Repeals subsection (c), which allows a city to extend its extraterritorial jurisdiction when a county is not enforcing zoning and subdivision regulations in an area or when the county has approved of the city’s extension of extraterritorial powers.
