Microsoft will move its San Francisco office to the Financial District's "crown jewel," located at 555 California St., renting the second and third floors. The San Francisco Microsoft office specializes in sales, marketing and engineering, and the employees won't have to move very far away.
The average price of office rentals in the area is about $58 per square foot, while Microsoft is expected to pay $62 per square foot. The 555 California Street building is the second tallest building in San Francisco, and is easily noticeable as it stands above the Financial District.
Microsoft also has a Silicon Valley location in Mountain View, California, where most of the company's regional employees work. Microsoft reportedly wants to expand into Sunnyvale in the near future, though an exact location hasn't been selected.
I've attended meetings and tech training sessions in the current Microsoft San Francisco office, and believe moving to a separate office building will be ideal. If visitors know to enter the Westfield mall and how to get on the elevator and find the appropriate floor, it's easy - but first-time visitors sometimes end up aimlessly wandering around in circles.
