Can I be evicted if I pay my portion of the rent but my roommates don’t?

Yes. Most leases have a joint and several liability term making each roommate responsible for the entire rent.  That means if one of your roommates doesn’t pay his rent, your landlord can evict every roommate unless the rent is paid in full within the time frame stated in the notice.  However, whether to hold everyone responsible for one roommates failure to pay, is up to your landlord.

What happens if my security deposit is not enough to cover all the damages?

For what reasons can my landlord evict me?
