The voting system is used for all mayoral elections in Italy, in the city with a population higher than 15,000 inhabitants. Under this system voters express a direct choice for the mayor or an indirect choice voting for the party of the candidate's coalition. If no candidate receives 50% of votes, the top two candidates go to a second round after two weeks. This gives a result whereby the winning candidate may be able to claim majority support, although it is not guaranteed.

The election of the City Council is based on a direct choice for the candidate with a preference vote: the candidate with the majority of the preferences is elected. The number of the seats for each party is determined proportionally.
