Figures cover office space listed on the platform in the Orange County office market. Square footage is rounded. Net listing activity is space added to the platform minus space removed. Dates show when space came on or off the platform. "30 DAYS" covers 4 survey weeks (AUG 24, 2026 – SEP 20, 2026), the same rows the Scoreboard, Change Report and Leaderboards read.
On the map, each circle's area is the submarket's listed square footage and its tone is the direction of its net listing activity over the same window. Rank changes in Market Share cover the weeks of brokerage history we hold (20 weeks) and widen to twelve months as the record grows.
