Zoning and Unrelated tenants limit per unit

[Andri Artayudianto]

Hi BP, I see a lot of duplexes and triplexes that are actually RSA-5 districts as apposed to RM districts. 

And many units housing unrelated persons above the legal limit of number set by the city (5-6 unrelated people in a unit with a legal max number of 3). 

Are these common practices that we shouldn't worry too much about?
