You can make it easier to supply housing, but you also need demand. I don’t expect there is terribly high demand for housing in Minneapolis. Especially compared to the cities with the highest rates of housing shortages.
Though, in fairness, that's after a lot of decades of little to no growth. The population of the city of Minneapolis is still less than it was in the 50s. (Though the metro area has grown steadily.)
Why not? Why wouldn't people want to live a city with such beautiful weather year-round??? /s
