Within 4 studio apt that share a bathroom how many occupants should be allowed?

I live in newport beach and the studio that I rent alone is $775 utilities included. When I 1st moved in there were 1 person per studio because we share a bathroom. 4 people is hard enough to share a bathroom with but I can live with it considering my location and price. Well we have new management now and they rented one of the units to 3 men and one had his gf over most the time. So we were sharing one bathroom among 7 people now. One of the guys moved out then the gf stopped coming around. So things got quiet and i let it go and dealt with sharing among 5 people but now they are moving a lesbian women in and her gf is here in and out as well. So we are back to sharing between 7 people one bathroom. My door is closest to the bathroom and we need a revolving door now. I'm late for work frequently because i can't get into the shower and the door is slamming all day long and they are all filthy. I pay $775 a month to share a bathroom among 4 people not 7. They are paying less then 260 each. That is fine by me if they wanna save money but they need to rent a unit with a bathroom and be considerate of the other tenants who pay full price. Is this legal??? I know in california you are allowed 2 people and one baby under 6months old per bedroom. So technically 2 are allowed in there unit. But what about a shared bathroom situation. The law should be different, like 1 occupant per room. I just wanna know before i have a little chat with the landlord tomorrow.. Thank you in advance for your help and 5 stars for best answer. :)
