After five years of the worst housing market since the Great Depression, home building is finally recovering. In 2012 residential building permits (single family and multifamily) were up 34 percent. In Salt Lake County the number of permits was up 27 percent, Utah County 34 percent and Davis County nearly 80 percent. Detached single-family permit activity was even stronger with a 42 percent increase statewide. Home builders are very optimistic about the spring and summer markets. In three major counties; Davis, Utah and Washington single-family building activity was up more than 50 percent in 2012.
