Do I have to put up a month-to-month tenant while I do repairs?

[Tracey Solomon]

Hi - i have a rental in Philly and the ceiling in the bathroom caved in after a particularly bad flood. The bathroom needs to be redone, which will take some time. In the meantime, I've asked my month-to-month lease tenant to vacate and basically find a new place to live because the bathroom cannot be used (it's the only bathroom in the house) and it will be awhile before it gets redone. He told me he has no place to go. How do I address this? Am I legally required to put him up somewhere (on my dime) while I fix the house? He's on a month-to-month so I would prefer to give him notice so he is free to find a new place and I can take my time to do the renos properly.

Thanks!
