Question about the legality surrounding Section 8 and inspections

[Account Closed]

Just wanted to poll the audience about something that was brought up in a recent episode of the podcast (ep. 356).

The guest mentioned that, as part of his extensive Section 8 application process, he conducts an inspection of the prospective tenant's current residence to get a feel for how they take care of their dwelling. My question is, are doing these sorts of inspections actually legal?  Somebody in another thread mentioned that this might be a violation of Fair Housing regulations.
