For accuracy's sake, he must live in the Tenderloin then, maybe at the NEMA apts. Twitter and Square are both in the Tenderloin, the Mission isn't really walking distance to that area (right on Market).

edit: Alternatively, he could live in the mission and then walk between the 2 offices during the day, they're right next to each other.

Twitter and Square are both in SoMa (around 10th St. south of Market), which is not considered part of the Tenderloin.

The Tenderloin's on the opposite side of city hall.

Makes sense. I have zero sense of San Francisco neighborhoods, I just read that he lives near both.
