Habitability is the conformance of a residence or abode to the implied warranty of habitability. A residence that complies is said to be habitable. It is an implied warranty or contract, meaning it does not have to be an express contract, covenant, or provision of a contract. There was no implied warranty of habitability for tenants at common law and the legal doctrine has since developed in many jurisdictions through housing laws and regulations.
In order to be habitable, such housing usually:
- must provide shelter, with working locks
- must be heated in the winter months (typically between October 1 and May 31 in the Northeastern United States)
- must not be infested with vermin, roaches, termites, or mold
- requires the landlord to stop other tenants from making too much noise (as measured by the decibel scale), second-hand smoke, or from selling narcotics
- must provide potable water
- each jurisdiction may have various rules.

Violation of the warranty of habitability results in constructive eviction, whereby the landlord or lessor has, in effect, evicted the tenant or lessee. The tenant may remedy the problem, or complain to local government authorities for remedies.
