Residential Building Permits and Estimated Completions by Type
The links below provide data on residential building permits obtained from the U.S. Census Bureau and data on housing stock and completions estimated by the Washington State Office of Financial Management.
We now report annual permit data for counties and cities in two dashboards, both of which have links below. The annual data are first published in February when the Census Bureau releases preliminary figures for the previous year. The data are updated in May with final annual estimates of the numbers of building permits. We no longer publish monthly data as it is not as reliable as the annual data.
The third link provides annual housing stock data for counties and cities, starting with 2020 and completions data starting with 2020-2021. Total numbers of units are provided as well as numbers of units by building type (single-unit buildings, two or more unit buildings, and “mobile homes and specials”). These data are updated in July each year.
