Liability is cured by purchasing proper (or additional) insurance 

They need to know that failure to properly care for or control **will** result in a notice to cure. know your lease provides for routine inspections of your rentals for all tenants. have to provide *PROPER* documentation for you to make a determination on whether or not they are qualified to make a request and if so, if the requested accommodation is reasonably doable.

Don't get shortsighted, remember your goals, and know that sometimes patience is the only cure.
