A tenant can be evicted for causing a nuisance. A "nuisance" is a pattern of behaviour by a tenant which threatens the health, safety or comfort of other tenants or other building occupants. In order to be grounds for eviction the nuisance must usually be continuous or persistent.
Examples of nuisance include the creation of health or fire hazards, illegal drug use or sale, excessive noise, property damage, and the like. Chronic late payment can also be cause for eviction although some judges require the late payment to be a purposeful act intended to annoy the landlord.
There are special rules regarding pets. If the lease contains a "no pet" clause, such clause will be enforced unless the tenant keeps the pet "open and notoriously" for a period of time and the landlord fails to act promptly. However, even in this situation if the pet creates a nuisance, i.e. excessive barking which disturbs the neighbors, this can still be grounds for eviction.
