Custom and Spec Home Market Shares in 2015

Custom home building registered declining market shares across all regions of the Unites States in 2015, except the New England and East South Central division where the custom home share of new single-family starts remained stable and relatively high. NAHB’s analysis of the most recent Census Bureau’s Survey of Construction (SOC) shows that New England registered the highest custom home market share, close to 43 percent. The East South Central division where custom home building is also common, showed the second highest market share of 39%, though a few percent down since a year ago.
