Permits and Completions

Residential Building Permits and Estimated Completions by Type

Any analysis of housing markets and development activity must consider new housing supply. Housing strategies revolve around issues such as having enough housing in the pipeline being developed of a certain type. Since demand for housing can change quickly and supply is slow to respond, planning responses should be based up knowing what types of construction are being proposed and what has recently been completed. When housing affordability issues arise, these supply considerations take on greater importance.

The links below provide data on residential building permits obtained from the U.S. Census Bureau and data on housing completions estimated by the Washington State Office of Financial Management. The building permit data are provided on an annual (calendar year) basis for 2016 through 2020 and also on a monthly basis starting with January 2019 (for most cities). The residential completions data are provided annually for years starting April 1 each year (this is because they are based in part on the decennial census that occurs on that date). The first link below provides completions data for 2016/17 through 2020/21, while the third link provides updated numbers for 2020/21 based on the 2020 census as well as estimates for 2021/22.
