Information for the Heavy Hitter lists was supplied by brokerage representatives through a nomination form. Only office transactions on the landlord rep side closed during 2021 are considered for this category and may not include all activity for the broker or agent. All agents are required to provide a spreadsheet verifying square footage and number of transactions per each category entered. Square footage reported requires shared deals to be split among coworkers handling the deal. All square footage rankings represent just the agent’s portion of any deal. Representative deals reflect total square footage of the deal, not the agent’s portion for shared efforts. The top 25 listmakers are credited with leasing a combined total of 7.7 million square feet for the office landlord side in 2021, up from almost 4 million s.f. leased in 2020. Thresholds reached by listmakers for 2021 still do not reach pre-pandemic amount of 9.32 million s.f. in 2019.
