In November, three out of four voters in the city of Los Angeles agreed to raise taxes to build homeless housing. The overwhelming support for Measure HHH, which authorized $1.2-billion in bonds to construct 10,000 units of housing for homeless and very low income people, sent a clear message: Angelenos want to end the city’s homeless crisis, and they’re willing to pay to make it happen.

Now, Measure S on Tuesday’s ballot could not only undermine the passage of HHH, but reverse the city’s progress toward ending homelessness. Because of the land-use restrictions in Measure S, some low-income and homeless housing projects would be blocked for two years, others would be stopped altogether, and still more projects could become prohibitively expensive to build because the initiative limits the city’s ability to reduce the number of required parking spots.
