Homes in Richmond County

Half of Richmond County's 19,900 housing units were built before 1976: 41 percent before 1970 (22 percent statewide), 57 percent before 1980 (nearly all before the state's 1978 insulation rule) and 7 percent in 2010 or later (16 percent statewide). The largest share went up in the 1960s; fiberglass from those years may have settled, so check its depth against the joists.
