This week the Radius+ team took a closer look at the Seattle-Tacoma-Bellevue, WA CBSA. 

Historical Supply Growth in Seattle WA:

2022: 1.9%

2023: 1.1%

2024: 1.6%

2025: 1.6%

Seattle has maintained measured supply growth in recent years, avoiding the overbuilding seen in some other large metropolitan areas. The region’s dense population, geographic constraints, and high incomes contribute to sustained demand for storage. Strong economic growth and a resilient job market led by the tech sector further support rental rate momentum. As long as development remains measured, operators should see steady rate upticks. Seattle’s constrained land availability continues to reinforce stable long-term fundamentals.
