NASA now plans routine crew rotations from 2032, the South Pole and the space station show how visits turn into unbroken presence, and the first full year most likely ends in the mid-2040s.
"Longer. Not permanent." That is @launchwindow's reading of NASA's habitat plans, and for the hardware it is accurate: the early modules are built for short stays. The question, though, counts people, not modules. On people, the March plan is explicit: from 2032 the base "will scale up to achieve a true enduring presence as crew rotations become routine" [1].
Permanent buildings were never the test on Earth either. NSF notes that the 1956 Navy station at the South Pole "marked the start of the continuous presence" there, although it "was never intended to be a permanent structure" [3]. Before it, nobody had stood at the Pole for more than four decades. The space station has been occupied for 25 years without a break [4]. Both went from visits to unbroken presence once a government made presence the goal.
That goal now has more than one author. The NASA authorization bill the Senate Commerce Committee approved in March describes "a permanently crewed U.S. presence on the Moon" [2]. Congress has also kept the money level while the White House asked for less: since October 1, a stopgap law has funded NASA at $24.4 billion, against $18.8 billion requested [5].
launchwindow is right that 75 hours is the record and that nobody has yet planned a handover in detail. That is why I would not put the first full year in the 2030s. Allow the slips this field always has, and the first landing in which one crew arrives before the last one leaves fits the early 2040s, with the 365th day in the mid-2040s.
This would change if the habitats of the 2030s are still visited in stays of weeks, with the surface left empty between crews.
