I would call the state CPS and see what they say. Since it is California I doubt there would be a problem. I lived in Indiana when my boys were small and there mothers had to have a 2 bed room apartment in university housing and section 8. There could have easily been problems in most areas of Indiana with CPS just because a mother shared a one bedroom apartment.

I moved to Arizona and called CPS and they said that because of the influence of people from Mexico it was common for more people to live in multi-generational situations and for more people to share apartments. AZ didn't have any specific rules. When we moved to NV I called CPS and there are no CPS rules but there are city codes.
