Findings from the Initial Use of the Healthy Homes Rating System (HHRS) in Three American Cities

HUD’s Healthy Homes Rating System (HHRS) is a modification of the English version, using scoring values developed in England. The goal of the HUD Three-City Healthy Homes Rating System (HHRS) study was to create a baseline of the prevalence and severity of 29 home health hazards in three cities—Detroit, MI; Greensboro, NC; and Alameda County, CA—and to compare the results to the prevalence and severity found in England. We analyzed 978 housing assessments over 3 years. Hygrothermal hazards (e.g., excess cold) were the most prevalent across the sites. However, significant differences in the type and severity of hazards across communities were found and were more severe in US sample homes than in their English counterparts. The results suggest that the tool shows promise in its ability to identify home health hazards.
