About this ranking

Number of new privately owned housing units authorized by building permits in the year or month, from the US Census Bureau Building Permits Survey. Annual totals for the nation, states and counties; monthly counts for the nation and states.

Counts housing units, not buildings, starts, completions or sales. Monthly counts are not seasonally adjusted and do not add up exactly to the annual total, which includes later corrections; the national seasonally adjusted annual rate in the monthly New Residential Construction release is a different measure.

Every value in the ranking comes from the same publisher and the same period, so the cities are compared on one definition. Equal values share a rank.
