I think the site to look it up on is the ada.comMarci  Fair housing is different than ADA.

I have learned so far that HUD and the ADA have different assessments of ESAs and service animals. 

You can require return to prior condition even for ADA accommodation. 

@Deodat Ramdat so all in you'd be about 60K (I'd ad a buffer on this to be safe).

Considerations need to be made for possible additional stairways, elevator for ADA compliance and sprinklers.

The thing I think might come up is the ADA accommodations for the mom.

In addition, we will have a local home inspector there to give a few tips on what to look for in a home inspection, and I will be sharing the latest market stats for Ada and Canyon Counties. 

Making accommodations for people with disabilities...There is a difference between making an accommodation for a person with a disability upon request vs. making a unit accessible to ADA standards and marketing it as such.

So, if your mother is awaiting transport to an appointment and can't get to the lobby on her own and requires assistance which is denied then the ramifications of such acts may constitute noncompliance to ADA.

I run a NPO that does affordable housing for disabled veterans - individual housing in not normally subject to ADA but does come under Fair Housing Act.
