Due to redistricting and the 2020 changes to the New York City Charter, councilmembers elected during the 2021 and 2023 City Council elections will serve two-year terms, with full four-year terms resuming after the 2025 New York City Council elections.[6]
In 2019, voters in New York City approved Ballot Question 1, which implemented ranked-choice voting in all local elections. Under the new system, voters have the option to rank up to five candidates for every local office. Voters whose first-choice candidates fare poorly will have their votes redistributed to other candidates in their ranking until one candidate surpasses the 50 percent threshold. If one candidate surpasses 50 percent in first-choice votes, then ranked-choice tabulations will not occur.[9]
In 2020, Councilmember Donovan Richards was elected as Queens borough president, triggering a February 2021 special election for his seat. Like most municipal special elections in New York City, the race was officially nonpartisan, with all candidates running on ballot lines of their own creation. It was also the first in the city's history to utilize ranked-choice voting (although an earlier special election in the 24th district was nominally ranked-choice, one candidate won with a majority in the first round).

In 2012, Councilman James Sanders Jr. was elected to the 10th district of the New York State Senate, triggering a February 2013 special election for his seat. Like most municipal special elections in New York City, the race was officially nonpartisan, with all candidates running on ballot lines of their own creation.
