What's a word to refer to unrelated people living in the same house? By this, I mean that they are not spouses or blood-related.
Basically what's the "house" version of "room-mates"?
I've thought of "cohabitant", "coresident", or even "housemate" but these words give the connotation that the persons involved are related.

You can use roommate, housemate, flatmate and similar terms to indicate that two unrelated people live together. None of these words imply any particular relationship (unlike cohabitation, which suggests that they have a sexual relationship or partnership).
Wikipedia notes a usage difference between American and UK English:
Thus, you can use housemate anywhere to indicate that two people simply live in the same house. In American English, you can also call them roommates.
