Construction activity has been occurring disproportionately in the urban core. At the beginning of 2020, the CBD construction pipeline was 3.9% of existing inventory, while in the suburbs the equivalent of 2.0% of inventory was under construction. In CBDs, 4.1% of current inventory is comprised of space delivered over the last four years while outside of urban cores, just 3% is. This elevated construction activity creates opportunities for occupiers looking for the best office product, but it has also put upward pressure on CBD vacancy rates as new construction has accounted for over 40% of the increase in vacancy over the past four years.
Office construction activity is slowing and will continue to moderate through the middle of the decade. In fact, over the next four years, the North American office market is forecast to deliver just over one-third of the space that came online since 2020 (66 msf vs. 185 msf).
