If you have a requirement that the UBI be for citizens only, or for residents only, you've already introduced bureaucracy.

As for a "does this person actually live in this area" criteria, I have a hard time seeing that single thing alone as "bureaucracy" -- it's quite common.
Of course, a GMI also differs from a UBI/NIT because that term generally refers to means-tested welfare with a sharp (usually 1:1 but not >1:1, which sometimes happens with means-tested welfare programs in aggregate in some ranges) cliff at starting at $0 in outside income up to the level of the minimum guarantee, whereas UBI/NIT benefits have a (usually much) <1:1 clawback via the tax system.
