Prop C is a charter amendment that would put more of San Francisco's budget into affordable housing. Voters created the Housing Trust Fund in 2012. The city paid about $52 million into it this year, according to the League of Women Voters of San Francisco.

What it does

  • Starting in fiscal year 2028-29, yearly payments would rise until they reach $125 million, which SPUR expects around 2036. After that, growth would be capped at 3% a year.
  • The city could freeze increases when it projects a deficit of $250 million or more. It could cut the payment by up to 10% in a year it draws on its Rainy Day Fund, GrowSF said.
  • The income limit for down-payment loans would rise from 120% to 200% of area median income. Supervisors could change that limit without a vote, the League said.
  • The fund could pay for social housing, co-ops and housing-related streets and utilities.
  • The fund's end date would move from 2043 to 2058.

Cost

GrowSF, citing the city controller, said Prop C would add about $6 million in General Fund costs in 2028-29, rising to about $60 million a year by 2034-35. The controller also noted that it doesn't follow a city policy that discourages new spending mandates.

Who is for and against

Supervisors put it on the ballot 11-0, GrowSF said. The League listed supporters including the Non-Profit Housing Association of Northern California, YIMBY Action and the SF Democratic Party. The SF Republican Party is opposed. SPUR supports it, saying the freeze rules give the city enough flexibility.

Also on the ballot: Prop I, the House SF transfer tax measure.
