In San Francisco, a coalition including Mayor Daniel Lurie, building trade unions, and community organizers is advocating for Proposition C. This measure seeks to more than double the city’s annual funding for the construction and preservation of affordable housing. 

If approved, the measure would implement annual contribution increases starting in 2029, aiming to reach $125 million with potential 3% annual increases through 2058. Supporters suggest this structure will help stabilize housing production against economic cycles.
