Im confused on the 1 year rule

[Viral Jhayyy]

So with the new conventional loan coming next month and the fha loan which is already in place they both require you to  live in your house hack for 1 year before renting or moving out . So the question is if I have a triplex do i have to wait 1 year to rent out the other to 2 rooms to people or does the 1 year rule only apply to the room i am staying in . sorry if this question is confusing i dont know how to put it
