Prior to 2025, Portland used a
city commission government, the last major city to do so. The mayor and commissioners were responsible for legislative policy and oversaw the various bureaus tasked with day-to-day operation of the city. The mayor served as chairman of the council, and was responsible for allocating department assignments to his fellow commissioners. The mayor's power included declaring an emergency and acting as
police commissioner. Beginning with the 2025 mayoral term, Portland switched to a Council-Mayor form of government. The executive mayor works with a professional city administrator to implement the laws enacted by council and administer the city’s bureaus, employees, facilities, and resources. The executive mayor develops and proposes the city’s budget to council for review and approval, may introduce measures before the council, and breaks tie votes in the council. == Elections ==
