Square leased an additional 4 floors in their HQ building at 1455 Market St, bringing their total square footage up to 474,614-SF. As part of their expansion, they elected to renew their lease early to protect against future rent increases, in the wake of a massive leasing wave from the Fortune 500. Square’s transaction ranks only as the 6^th largest for the year, falling behind Facebook, Splunk, Nektar Therapeutics, GM’s Cruise Automation, and WeWork. These six companies alone have leased 2 Million-SF in the first half of 2018.
