JANIE HAR and TERRY CHEA.

San Francisco has banned homeless people from living in RVs with a new citywide parking limit of two hours on large vehicles. The proposal by Mayor Daniel Lurie also calls for a new permit program to help people living in RVs move into housing. This is part of the mayor’s pledge to clear San Francisco’s streets. People registered in RVs as of May will get a permit exempting them from parking limits. In exchange, they must accept housing options when offered and give up their RV. Critics say the city doesn’t have enough housing to help everyone. RV dwellers say they can’t afford rent no matter how much they work.
