One of the most important foundations in landlord-tenant relations is the concept of habitability. The concept of habitability and landlord-tenant relations generally holds that

A) Repairs affecting habitability must be made within a 48-hour time period from the tenant's notice.
B) Residential landlords must, at their expense, maintain the rental premises in such a condition that the health and safety of the tenant is not adversely affected in any material way.
C) The tenant must maintain the habitability of the premises as it existed upon taking occupancy.
D) The tenant is responsible for repairs inside of the premises while the landlord is responsible for the availability of the overall property.
