Which of the following services must landlords provide to tenants?

Landlords are typically required to provide a habitable living environment, which includes maintaining the property and addressing any pest control issues that may arise during a tenant's occupancy. This is why exterminating services fall within the responsibilities of landlords; they must ensure that the rental unit is free from pests that can affect the health and safety of the tenants.

While personal cleaning services, home security systems, and furniture and appliances might enhance a tenant's experience, they are not typically mandated by law or standard rental agreements. A landlord's primary obligation is to provide safe and livable conditions, which includes handling pest control issues to comply with housing regulations.
