Final answer:
Actual eviction can occur due to hazardous materials on the premises, constituting a lease agreement breach and violating health and safety standards.
Step-by-step explanation:
A reason for actual eviction would be a violation such as hazardous materials on the premises. Actual eviction occurs when a resident is legally removed from a property due to a breach of the lease agreement.
The presence of hazardous materials might violate health and safety standards, which are typically outlined in lease agreements. In contrast, the transfer of a property to a new owner, a tenancy at sufferance, or a violation of quiet enjoyment do not constitute reasons for actual eviction as they do not directly involve breaches by the resident that would warrant legal removal.
