The winner of the election will serve until 2020, filling the unexpired term of Ed Lee, who was elected in 2011 and 2015, and died in office on December 12, 2017. Upon Lee 's death, London Breed, President of the San Francisco Board of Supervisors, became Acting Mayor of San Francisco, but a vote of six supervisors replaced Breed with Supervisor Mark Farrell. The mayoral election was held concurrently with the statewide direct primary election. In San Francisco, the election for the eighth district member of the Board of Supervisors was also on the ballot. Eight candidates qualified to appear on the ballot, and a ninth qualified as a write - in. The four major candidates were former Supervisor Angela Alioto, former Acting Mayor London Breed, Supervisor Jane Kim and former State Senator Mark Leno. All four main candidates identify as Democrats, though the position is officially nonpartisan per the Constitution of California. Leno conceded the race to Breed on June 13. Contents 1 Background 2 Candidates 2.1 Qualified 2.2 Declined 3 General election 3.1 Endorsements 3.2 Polling 4 Results 4.1 Results summary 4.2 Vote counts by round 5 References 6 External links Background Ed Lee, who was appointed Mayor of San Francisco in 2011 following Gavin Newsom 's election as Lieutenant Governor of California, elected to a full term in 2011, and reelected in 2015, died of cardiac arrest on December 12, 2017. London Breed, the President of the San Francisco Board of Supervisors, became the city 's acting mayor. On January 23, 2018, the Board of Supervisors selected Mark Farrell to serve as interim mayor until the special election could be held. Citing Ron Conway 's role as a benefactor to Breed, Supervisors Aaron Peskin and Jane Kim, considered the progressive members of the board, sought to deny Breed the benefits of incumbency going into the election. As San Francisco elections use ranked choice voting, Kim and Mark Leno chose to align with each other, each endorsing the other as their preferred second choice. Candidates The filing deadline was 5 p.m. on January 9, 2018. Qualified The following eight candidates qualified for the ballot by filing all nomination documents and paying the filing fee. The deadline for a candidate to drop out of the race and remove himself or herself from the ballot was January 30, 2018.
