The government views ESAs the same as a wheelchair. 

About to rehab a duplex, which has an access ramp but the ramp needs work, and cramps the front yard and will require ongoing maintenance. Should I remove or update? What are the pros vs cons of having a rental proper...

After speaking with them, they took it off the market and we entered into a rent-to-purchase agreement.Just months after moving in, in Dec of 2015, my husband had a horrific accident, hit a deer and cartwheeled his SUV "multiple times", requiring a month in ICU, 3 months in a wheelchair, multiple surgeries and months of rehab and a walker; about 9 months out of work originally following the accident which was most of 2016 and about 6 months out of work each in 2017 and 2018 for follow up surgeries.

Now 2 years after that she needs an handicapped kitchen, wider door openings, and a ramp for her new wheelchair. 

Keep in mind possibly a walker or wheelchair in the future.

ESAs are not pets, they are basically equivalent to wheelchairs.

The law looks at these type of animals - not as pets - but as the equivalent of crutches or a wheelchair.

The ESA is like a wheelchair as far as the government is concerned.

In any case, just remember that those bleeding heart liberals with participation trophies are going to be pushing your wheelchair in the not too distant future.  

On the other hand, I think the future will place a great deal of value on a ground floor, wheelchair accessible suite as the proportion of seniors continues to grow.
