Housing in Portland (particularly rental housing) is getting less affordable by the day, and the city is very aggressive about land use planning. This is, of course, one reason why the city is so nice... but it also means that there is a very fixed amount of buildable space, literally all of which is already taken. Infill is certainly happening, but the city really can't absorb any larger of a population increase than it already has over the last couple of years.
