It is laid out on page 168 of the proposed zoning ordinance. "no more than four (4) unrelated persons...where tenany is either by ownership or on a month-to-month basis or longer. Uses where tenancy is arranged for time periods shorter than one month are considered Lodging uses" then you have to go to lodging section to read about that.

So yes, if you have 5 or more bedrooms, you can still have only 4 unrelated people as long term tenants. The organizer said in his testimony that he has a 6 bedroom apartment. There is some additional risk with that many people and I'd never want to be the landlord or tenant in that situation, but I don't consider it overcrowding. Also I don't know why the proposed ordinance doesn't prohibit 4 people from occupying a 1 BR.
