cities should allow up to 6-story buildings in residential areas, because that's the reasonable max height of a wood frame building (it used to be 4 stories, but i hear construction practices have improved to allow up to 6). wood frame is cheaper to build than either concrete or steel, which are the other predominant building materials (which allow much taller builds). http://missingmiddlehousing.com/ http://missingmiddlehousing.com/
