The Seattle metropolitan area saw a significant increase in multifamily permit activity in 2021 compared to the previous year, led by King and Pierce counties—up 71% and 31% respectively. More than 22,000 multifamily permits were issued in the three-county metro area last year, surpassing pre-pandemic levels of fewer than 19,000 multifamily homes in 2018 and 2019. Single family permits were also up 24% in Pierce County year-over-year. Meanwhile, Snohomish County had a modest decrease in permits last year compared to 2020. King County ended the year down 8% for single family permits.

Severe shortages of housing inventory for sale continued in December, with only 0.27 months’ supply (about one week) in King County and 0.20 months’ supply (less than a week) in Snohomish County. This represents a decline from the previous month and year-over-year. The snow and cold temperatures also impacted home sales in December, according to the Northwest Multiple Listing Service.

Despite headlines about a housing market cooldown and home prices dipping slightly compared to last month, median housing prices continue to rise year over year, with an 8.03% rise and a 22.29% rise in King and Snohomish counties, respectively, for combined single family and condo sales. Likewise, for-sale housing supply continues to drop, with both King and Snohomish counties—and much of the state—more accurately described as having weeks of supply, not months. Year over year, months of supply dropped 59% in King County and 37% in Snohomish County. There is at least some relief on the horizon, however, as year to date residential building permit activity is up 30% in our two-county region.
