Generally, to be eligible to vote in a city election a person must, among other things, reside in the city on the day of the election. TEX. ELEC. CODE § 11.001. (As used in the Election Code, the term “residence” means domicile or “legal residence” and not necessarily the actual place where a person is living for the time being. Id. § 1.015.) There are some exceptions to this general rule. For instance, a city that seeks to annex an area with a population of 200 or more must get, at an election, the approval of a majority of the qualified voters in the area. TEX. LOC. GOV’T CODE § 43.0691; see also, e.g., id. §§ 42.904, 43.130.
