I was going through the rent control laws ( I know, should have done that before purchasing the property ), and a section stands out. https://ecode360.com/30526708#42037155Based on what I can read, the rent control chapter doesn't apply to: Dwellings of three and four units, at least one of which is occupied by one or more of the owners thereof.My understanding is that rent control doesn't apply to owner-occupied multi-units.
