The Bay Area Life Science market produced 959,769 SF of gross absorption and 222,682 SF of positive net absorption in Q4 2022.
Annually, 2022 totaled 3.7 million SF of gross absorption and 1.5 million SF of net absorption. The Life Science market had much less leasing activity than 2021 (5.5 million SF of gross absorption). Despite the year-end slowdown, 2022 was a very strong year overall with a low vacancy rate of 3.8%, falling 40 basis points (bps) quarter-over-quarter.
In the fourth quarter, San Mateo County led the entire Bay Area with 482,730 SF of gross absorption followed by Alameda County with 313,724 SF. New Life Science development continues to thrive in the Bay Area, with 7.9 million SF under construction with majority of the region’s construction activity within San Mateo County. The trend of conversions from office, industrial, and tech buildings into Life Science remains strong and will continue to help satiate the demand and drive market growth by providing additional spaces for lease. However, many planned development projects will continue to be delayed due to inflation and ongoing supply chain issues. Despite recession concerns, there is still strong demand for lab space with 3.4 million SF of tenant requirements currently being tracked by Kidder Mathews.
