Renter glossary
Warranty of habitability
Definition
An implied promise in most states that a rental will be kept fit to live in — heat, water, working plumbing, and safe conditions.
Why it matters to renters
It's why a landlord generally must make essential repairs; if they don't, you may have options set by your state.
Example
No heat in winter or a serious plumbing failure can breach the warranty of habitability.
