The extraterritorial jurisdiction (ETJ) is an “unincorporated area that is contiguous to the corporate boundaries” of a city. TEX. LOC. GOV’T CODE § 42.021. The ETJ, a concept created by the Texas Legislature in 1963, is said to be established in order “to promote and protect the general health, safety, and welfare of persons residing in and adjacent to” cities, a sort of buffer zone outside of a city’s corporate limits. Id. § 42.001. Despite this, cities have been granted relatively little authority to address health and safety issues in the ETJ. Thus, some argue that the real purpose of the ETJ is to limit the geographic area in which a city may annex.
