He and his wife have recently moved 7 hours away for his wifes health/ allergy reasons and do not want to manage the property long distance. 

Ok, so lets say a landlord had a building that was specifically marketed towards tenants who have allergies.

We share the same legal address, utilities and airways.In this specific living environment with a spouse that has been hospitalized with allergies due to pets, can we decline to accommodate assistance animals in our own home residence?

I have been able to buy Christmas gifts for children in need, donate supplies to families who were devastated by a house fire, purchase electric lawn mower for a home owner who had an allergy to carbon monoxide.  

There is mildew and many types of molds that are completely harmless, but there are a few that are toxic and all of them can be dangerous to people with allergies which is why you need to be careful.First thing you need to figure out is why you have it.

Mold allergies are real--I am allergic myself, and I applaud you for taking the complaints seriously and being diligent in remediating.

This tenant is extremely high maintenance and everything is a “health issue” because she has bad allergies she says but she has two cats and her apartment is a mess with cat pee and vomit everywhere.

Thanks for the welcome....yes it is beautiful up here, I'm originally from southern ca, but made the dash up here 20 years ago...much more green...not great for allergies, but...oh well.

You can rent a machine that will make very short work of removing that tile, and with very little effort on your part.I won't remove good tile unless it is the most butt ugly thing I've ever seen.Make lemonaid: emphasis that the house with it's tile floors is good for persons with allergies or that have pets.

Baseboard is a nice clean heat better for people with allergies , I would check the boiler and if checks out leave it as they are pricey to buy new or if you have the money and space rerun the system using pex below the floors as that heating system as my plumber says is better than you could even think.
