You should re-read your lease to understand the repairs that you and landlord are responsible for making on the residence. If you don’t have a copy of your lease, ask your landlord for one.
When a disaster occurs, the most important terms in your lease are the rent abatement or lease termination provisions. You have the right to terminate your lease if a significant part of the property is damaged or completely unusable. You also have the right to reduced rent until the property is completely repaired.
