LARGE Tenant Issue! ADA conflict?

[Jesse Waters]

I have a rather large tenant in one of my units, he is around 500lbs and on housing assistance.  Shortly after he moved in he managed to put a foot through the fiberglass bath tub, which we replaced with a cast iron tub.  His lease is now set to expire and we have given notice that we will not be renewing his lease.  Mainly because his weight is causing too much damage to the property and he really need to be in a place that has a slab foundation not a crawl space.  

This one is a new one on me. 

Do any of y'all seen any issues or hang ups with us asking him to leave?  

Tenant is near Columbia, SC.
