Habitable Housing

• Landlords are required to provide housing that is fit to live in. This includes removing and preventing rodent infestations. It is typically the tenant's responsibility to maintain the cleanliness of each unit. In some communities, landlords are responsible for the cleanliness of common areas such as hallways, laundry facilities and outdoor areas.
  
  

Repairs

• Landlords are required to repair any structural damage to the facility caused by rodents. Tenants are responsible to inform the landlord of any indication of rodent infestation or damages caused by them. If a landlord does not make repairs in a timely manner, some jurisdictions allow the tenants to complete repairs on their own and legally deduct the amount from their rent payment.
  
  

Cleanliness

• Most landlord and tenant law outline that responsibility falls on to the tenant to maintain a clean living environment, including proper disposal of trash and garbage. If neglect or abuse leads to an infestation of rodents, the tenant may be held accountable for damages done to the property.
  
  

Written Agreement

• When entering into a tenancy, each party should sign a written agreement that clearly outlines the responsibilities of the landlord and tenant. The agreement may also state the local department of health and housing laws required to be followed.
