There’s definitely a need as I spent some time looking at vacation rentals online for a relative who is wheelchair bound and I found nothing in the Albuquerque area that could serve the purpose.Good luck ahead!!

They are medical equipment, such as a wheelchair.

However, you will not be able to afford the rates.So, there is the undue burden on you as the landlord. that allows you to say you can not make accommodations for such an animal.It is the same as if a person applied for an apartment on the second floor and after being accepted stated they were in a wheel chair and since the apartment is on the second floor you as the landlord must install a ramp or lift that makes the second floor handicapped accessible.

You must treat the animal just like you would a wheelchair or a fake arm.2.

One was that there was a significant cost to make the units ADA compliant because I would have to make doorways and bathrooms larger for wheel chairs and the other was I tried to contact the list of agencies provided with the course and I hit a dead end on that after sending letters written exactly like a template provided with the course and I never received one response.

This is my new wheelchair accessible bathroom, with a roll in shower.

You can't charge anything, anywhere in the United States.You have to treat it like a wheelchair.

You could go overboard and put in ADA wheelchair width front door and bathroom door If you wanted to dedicate this unit long term to elderly customers.Just my 2 cents. 

In my earlier response, I did not intend to imply there is any reason to eschew stacked duplexes, triplexes - we have a couple and, as @Matt Geerts points out, no stairs on the ground level provides the opportunity to create an accessible unit for those in wheelchairs or other mobility issues {Matt, might consider this ... designing with wider hallways and doorways (36/38") and a more open bathroom layout (perhaps with walk/roll-in shower) is simple when building new or doing a major renovation.} and makes your unit appealing to new categories of tenants (those with disability and aging Boomers are but two).That said, when looking at an older residential building {i.e. without an elevator}, my preference is still for side-by-side units over stacked.

Even if he was 90 years old, sitting in a wheelchair, and covered in war medals.
