Ordinance 184836 was passed by the LA City Council and the Mayor of LA on March 29, 2017. This ordinance allows any government agency, religious institution, non-profit charitable organization or private non-profit organization to provide, emergency or temporary shelter for 365 days per year. What this means is that any faith-based institution or non-profit which meets certain minimal requirements can use their parking lot to safely park vehicles at night and allow people to sleep there without disturbance.
