How 3 Unrelated Tenants Rule applies to House Hacking

[Robert Meaux]

So I was thinking about housing hacking in Pittsburgh in the future and am trying to clarify this ‘3 unrelated tenants rule’ where no more than 3 unrelated tenants  can live together. If I’m living in one of the rooms since I’d be house hacking, do I count into that 3? Or would the house be able to have the 3 tenants plus me for 4 in total?
