The City of Brentwood operates with a City Administrator form of government. A mayor and eight-member Board of Aldermen serve as the city's legislative body. The mayor and alderpersons are elected to a two-year term. The regular meetings of the Board of Aldermen are held on the first and third Mondays of the month at 7 pm in the City Hall Council Chambers. During the summer months, the Board meets on the third Monday of the month at 6 pm. If a meeting date falls on a holiday, the Board meets on Tuesday of that week. Special meetings are held as needed.
