So much misinformation here. The lease has a termination clause and if it says pay fees, then she should pay. All of you saying fair housing or reasonable accommodation may need to retrain. To qualify for a reasonable accommodation you must have a disability. The definition of disability is any condition that is expected to last a lifetime. A broken leg is not permanent. It's inconvenient for sure but their responsibility to figute out. She has help to move, then they can help her live while recovering. No different than someone in hospital for a month or more, still have to pay rent. She's probably still working and one leg? That's just crutches. Again inconvenient but not the owners responsibility to figure out

Let her out of the lease. This falls under ADA Compliance. If you cannot accommodate and transfer the resident, you have to release them from the lease, and you cannot charge termination fees

Fair Housing. You have to get her a ground floor or let her out of her lease, no lease break penalty.

To risk law suit if she falls down stairs ask for 30 day notice no fees markets hot right know probably be able to release it at higher rent!! She probably will have a hard time finding accommodations and come back to cancel her notices
