The tenant offers to be accommodating which is great but what if I need to show their unit when they're not home?

As far as if they are actually interested in leasing, you must make reasonable accommodations for a disabled person, like allowing them to install a ramp, grab bars, widen doorways, etc. -- at their own expense, is my understanding.  

That only happens if the PM Company is not handling hundreds of properties or have more staff to accommodate it.

It has city water which is great (though it is officially just in the county), and a very large septic accommodating the entire place.  

My job was to coordinate all of the accommodations for people with disabilities (employees, patients, families) and the language/cultural support services for people with Limited English Proficiency.

We also have an addendum that says we have to show with 24 hour notice and work with the agent to accommodate that.

The city is demolishing the house and turning them into public parks.If the city used to have a large population, like Detroit, and has a huge stock of houses to accommodate that large population.

In the future when he calls you with a problem and complaint be less accommodating and more business like with him.

If that is the case, I would suggest they submit a claim with their renter's insurance policy to be reimbursed for their accommodations.

BUT when it comes to housing laws, "HUD does not have a training requirement for service animals....Emotional support animals and comfort animals would be included as a reasonable accommodation under HUD rules."
