@Steven Medaglia if they’re a good tenant I would allow the mother to move in and add her to the lease.In accordance with the ADA (Americans with disabilities act) you MUST accommodate their request to modify the property for handicap accessibility but you do not have to pay for it and can require them to return the property in its original condition when they leave all at their own expense.Good idea on the licensed contractor part.

You will probably need to look at Commercial policies (Business Owners or Package policy).Another consideration is the ADA compliant changes that are required for that use.

Aloha,"Service dog" is an ADA definition, which applies to public/commercial spaces.

One of the requirements to pass inspection,   regardless of when the structure was built,  is that the hand rails meet all current safety and ADA standards it turns out.  

In most cases, landlords are required by law to make reasonable accommodations for tenants with disabilities under the Fair Housing Act (FHA) and the Americans with Disabilities Act (ADA).

I think my biggest concern is or was ADA and how that applies to 5+. 

To get beyond the punches, another thing that you can do to increase the effectiveness of your signs is to ad a website address to them.

Under the ADA, tenants with disabilities are entitled to add safety features and are responsible to remove them and put the property back in the original condition.

Specifically looking at Ada and Canyon counties. 

I'm guessing this is why the law was added, but seems like these would fall under an ADA reasonable accommodation.
