As illustrated in Tables V-9 and V-10, housing conditions have improved dramatically since 1960; however, determining the exact level of improvement between 1960 and 2000 is difficult, because the classification method used by the U.S. Census Bureau has changed. Using the current classification system adopted in 1970, substandard housing has fallen from 38.0 to 1.8 percent of the total occupied housing stock in the county, while overcrowded housing has fallen from 10.0 to 1.6 percent.

A windshield survey conducted by Mount Rogers Planning District Commission staff in early 2005 resulted in a larger number of residential structures that appear to be substandard or deteriorated. Conditions were assigned using a ranking system that included an analysis of siding, shingles, windows, and exterior paint. Generally, if two of these characteristics appeared to be in poor condition (cracked or broken windows, missing shingles, etc.) the structure was considered to be substandard. A deteriorated structure appeared to have more than two of these characteristics in poor condition and seemed unsuitable for habitation.
