I just checked the MLS in Boise and there are only 24 multifamily listings in Ada and Canyon Counties. 

I highly recommend https://www.petscreening.com/about.If you insist on doing it yourself for some reason, they also have some great resources available at https://www.petscreening.com/hud-ada-fhact-links (and particular to your situation, https://blog.petscreening.com/our-analysis-of-huds-new-assistance-animals-notice)

(If they know the names of the correct tools and can tell you the details of what they have like nail guns and their gauges, and can bring them, they might actually know what they are doing somewhat) BTW, our framer used mostly nails ad a hammer; old school but he had a nice variety of different saws.

In many cases, Airbnb hosts are not required to make their homes compliant with the standards set out in the Americans with Disabilities Act (ADA) .

Also you could try running a test ad?

This is a challenge that I thought the forum may be able to help with:In the event that a tenant has a justifiable fear of dogs and suffers from PTSD from a previous attack (they even asked if it was a dog free property upon rental), what happens if a neighboring tenant states it is their legal right to acquire an emotional support animal because of the ADA laws?

(This makes it harder for someone else to steal them and use them with a different phone number/email address.)2) Don't post the actual address to the property in the ad. 

Overall they are low in cost, and I believe ad a great return.

I've read that these properties can qualify for up to 250% Fair Market Value (see link below) provided the property is handicap accessible and meets the various ADA standards and guidelines. 

The next thing is building requirements, from fire safety to bathrooms and ADA compliance.
