Breaking Lease due to flooding in Houston

[Anthony Ellison]

Hopefully someone can shed some light on this. My sister n law's apartment was flooded during the storms here in Houston. My question is what rights does she have in regards to breaking her lease. The complex is saying she still had to pay because the lights and air conditioning work. they said they are going to mop the floors and replace the sheetrock. if anyone has any insight on what her rights are as a tenant that would be a great help. Thanks
