Prop D raises the signature threshold to qualify a citizen initiative from 2% of registered voters to 8%, still lower than most peer cities, and ends the practice of a Mayor or a four-vote Board minority putting something directly on the ballot over a Board majority's objection.

This isn't abstract governance trivia for YIMBYs. San Francisco's rock-bottom signature threshold is exactly how a small, well-funded opposition group can lock in an anti-housing rule that the elected Board can never fix without another citywide vote. Raising the bar to put something on the ballot, and making it require an actual Board majority to route around normal legislating, cuts down on that vector for freezing bad housing and zoning policy into the Charter. Shorter ballots, more accountable lawmaking.
