The extent of a city’s ETJ could be different than what state law provides as the result of local factors and circumstances. For instance, a city that incorporates immediately adjacent to another city may have no ETJ at all. A more common reason for a city’s ETJ to be different than the distance limits in Section 42.021 is that the city used its authority to adopt an ordinance to bring land contiguous to its ETJ into its ETJ at the request of the landowners.
