Diamond Bar Voting Districts

Starting with the November 2022 municipal election, members of the City Council will be elected on a by-district basis. Under this election system, instead of casting votes to fill all five city council seats, Diamond Bar voters will only vote for one City Council candidate living in their district.

City Council seats for districts 1, 3, and 4 are up for election in November 2022, with the remaining districts 2 and 5 having elections in November 2024. Existing council members will continue to serve out their existing terms as at-large members until the end of their term in 2022 or 2024.
