Quoting
Mr. Knowitall
It's difficult to accommodate Tourette's in the same manner as most other disabilities, as the focus of the accommodation will typically have to be to try to make other tenants more understanding. Sometimes the tenant with Tourette's will help the landlord with an educational process, other times the landlord will have to try to act based upon knowledge of the condition without the tenant's help.
Given that the landlord references yelling and pounding, I expect that he's going to argue that the eviction notice has nothing to do with Tourette's, as Tourette's does not cause a tenant to pound on the floor/ceiling and that yelling that occurs in association with such pounding is reasonably inferred to be volitional - going along with the pounding - as opposed to involuntary. I'm speculating, of course.
It's possible to respond that all of the incidents were episodes of Tourette's, but that will be more complicated if the other affected tenants say that the issue was pounding, or yelling while pounding, whether or not that's true.
Your best bet at this point would be to try to team up with a disability advocacy group or legal aid association (assuming you qualify for legal aid) to build a defense to the eviction claim and, depending upon what you can document, a possible claim for housing discrimination.
