The tenant has the option of filing an application requesting that the tenancy be terminated and for a rent abatement for the period of time they suffered the loss or reduction of use of the property. Many tenants simply opt to leave and possibly sue at a later date. You cannot stop them from leaving, nor can you rely on the fact that they will vacate when they say they will even if they have received some kind of payment from you. To make it clear that you are taking the obligation to maintain the property seriously, ensure that you are entering the unit properly when doing the repairs. WRITTEN notice is required, at least 24 hours before the time of entry. A 2-3 hours window of entry such as “between 9 and 11 am” can be given and this particular notice can be put on the door.
