The I-5 Corridor industrial market, spanning Whatcom to Clark counties, is experiencing a period of adjustment. Vacancy rates have risen to 7%, up from the five-year average of 4.3%. Leasing activity has slowed, with net absorption showing a negative figure of over 2 million square feet. Despite this, construction remains active, with over 12 million square feet under development, although the volume of new construction starts is decreasing. High land costs, stabilized rental rates, and rising construction expenses are limiting new project pipelines. This trend may continue, particularly affecting developers and land sellers.
