San Francisco Proposition D — Changes to Ballot Measure Process
Last Updated: July 24, 2026

Proposition D
Changes to Ballot Measure Process
What is it?
Prop D is designed to reduce the number of local ballot measures San Franciscans vote on by:
- Raising the signature threshold for citizen initiative ordinances from 2% to 8% of registered voters, still below Oakland's 10% and Los Angeles's 15%
- Raising the signature threshold to call a special election on an initiative from 10% of votes cast for Mayor in the last election to 10% of registered voters
- Removing the Mayor's ability to unilaterally put a measure on the ballot
- Removing the ability of any four supervisors to bypass a Board majority, so six votes are required
Today a citizen initiative cannot be pulled off the ballot once its signatures are in, even if the sponsors changed their minds. Prop D lets all of a measure's proponents together withdraw it up to 102 days before the election. California gave statewide proponents a similar option in 2014.
