I've gone to the ADA County Assessor website where I'm able to find the property owner's name, but not much other info.

ADA specialist. 

Just be sure to check with your county zoning board regarding any additional requirements when increasing the number of beds.For example, you may be required to install a commercial fire suppression system, or you may have to adhere to Americans with Disabilities Act (ADA) standards, which might involve widening all doorways for wheelchair access and providing ramps at all entrances and exits.These costs could easily blow your rehab budget.Also, whatever guidance you get from the county, I'd make sure it was in writing, to prevent misunderstandings in the future!

Because of the nature of my client (government entities), 80% of the time, I DONT need a permit to pull a job, even if it's a bathroom ADA upgrade remodel say on a 100k job, but, I get daily visits by their own inspectors, minimum stays for 30 mins, and do their "documentation".

ESAs are not protected by the ADA. 

ADA requirements can be used to set up your house though not required as ADA does not apply to private residences.

I need a bathroom and a kitchen remodeled (bathroom ada compliance) I got one estimate but I was surprised that the contractor was easily able to provide a price but they didn’t show what they wanted to install or possibilities based on that price.

Most lenders will have a $50k minimum for properties that need rehab work ad a $75k minimum for refinancing rentals.

At the time, we were young and adventurous, so we bought the least expensive house in all of Ada County, Idaho, for $125,000.

We have seen that very few properties in that area offer accessibility features so we expect it to provide a differentiator.There is a big difference between ADA compliance and just adding a few features to make the property practically usable for folks with some forms of disability.
