Are GFCIs now required in all unfinished portion of a house?
GFCI outlets are not required anywhere.
In places GFCI protection is required, plain outlets can be protected by a GFCI device elsewhere (GFCI breaker, GFCI deadfront, or GFCI receptacle).  Doing so is the one and only legitimate purpose of the GFCI's &quot;Load&quot; terminals.  They should be used for nothing else; the &quot;Line&quot; terminals get all other wires, and they take 2 wires per screw.
When a plain outlet is protected by a GFCI elsewhere, it MUST have a label saying:

GFCI protected

and a pile of them come in every GFCI box.
Obviously, nobody ever does that LOL...  and then, they get written up for it.  And very often, this is interpreted as &quot;You need GFCI receptacles there&quot;.   Never true.
You need stickers there.  The stickers have to be not lying.
If the sticker is there, and a cheapie GFCI tester trips a GFCI somewhere, that's good enough.
I find the default blue stickers ugly, and I prefer to make my own on a Brother or P-touch labelmaker.  On a white cover plate they look perfectly fine.  I also consider it helpful to add a line stating where the reset is located.
