According to the National Association of Home Builders’ (NAHB) Remodeling Market Index, 24% indicated that they were building an addition for use as an ADU and 23% indicated that they were converting an existing space to an ADU. The percentage shares for each category rose compared to the last time NAHB asked the question in Q1 2019.
According to NAHB, when looking at how each region answered this question, the Northeast was most likely to have remodelers constructing ADUs, with at least one-third indicating both project types, such as building an addition and converting existing space, followed by the West with at least 27% of remodelers for both types.
