There are two sets of guidance HUD issues 2013 and 2020, you should read them both.Here is the only link that I can get to attach:Joint Statement on Reasonable Modifications - March 5, 2008 (hud.gov) 

I am not sure what could crop up at that close of quarters, but if you have written policies (lease or house rules) you could explain that your lender (or insurance or partner) expects you to follow the no modifications to unit, no pets, no smoking, no guests over 48 hours without approval, one vehicle, written policy.

Due diligence is vital to your survival.
