Colorado Revised Statutes Title 31. Government Municipal § 31-4-106. Councilman--residence--vacancies

Each councilman shall have resided in the ward in which he is a candidate for a period of at least twelve consecutive months immediately preceding the date of the election and shall be a registered elector therein; except that, in case the boundaries of the ward are changed pursuant to section 31-2-104 or 31-4-104 or as a result of annexation, any person who has resided within territory added to the ward for the time prescribed in this section shall be deemed to have met the residence requirements for the ward to which the territory was added. If any councilman, during the term of his office, removes from or becomes a nonresident of the ward in which he was elected, he shall be deemed thereby to vacate his office, effective upon the adoption by the city council of a resolution declaring such vacancy to exist. If any vacancy occurs in the office of councilman because of death, resignation, or removal or for any other reason, the same shall be filled by appointment by a majority vote of the city council or by election as provided in section 31-4-108(2)(b). A successor to the person so appointed or elected shall be elected at the next regular election.
