You can be kicked out of an apartment if you fail to abide with the tenant's rules. These include paying the rent in the right time. If you also disturb other tenants, you can get kicked. You can also get kicked out if you have an unruly pet.
Doing illegal drugs, conducting a p0rn0 shoot in the basement, peeing on the apartment lord or whatever they call him, failing to pay rent on time and.... (my favorite) being a threat to the rest of the apartment people
