Reuters- Uber’s new Oakland headquarters is about four times bigger than Internet radio service Pandora Media’s office nearby, and will house about five times the number of employees that ride-hailing competitor Lyft has at its headquarters.

The on-demand ride service paid $123.5 million for Oakland’s historic Sears building last year and has so far filed building permits to complete at least $2 million in renovations, according to BuildZoom, a startup that compiles construction and remodeling contractor data for homeowners.

Across the bay in San Francisco, Uber has so far initiated $130 million in construction on a bigger office in the Mission Bay neighborhood, BuildZoom’s data shows.

Uber's property footprint unmatched among S.F. Bay Area startupsThe new building permit data from BuildZoom, provided exclusively to Reuters, underscores the mammoth growth in Uber’s real estate footprint and associated costs, overshadowing most other tech startups in San Francisco and Oakland.

Remodeling on the good old Sears building will need another full year, and the Objective Bay campus is several years out still, so development costs shall rise. Uber said it had been also mending damage on the Oakland building due to the 1989 Loma Prieta earthquake.

Uber may be the most extremely valued venture-backed tech company and has raised a lot more than $7.4 billion from shareholders, a war chest that will help fund property purchases.

But its costly growth in San and Oakland Francisco comes as the capital raising investing climate cools, with more investors wary that highly valued startups may well not grow into their stratospheric valuation.

The iconic Oakland building, which opened in 1929 as a department store, will house between 2,000 and 3,000 Uber employees across 380,000 square feet (35,303 sq. m.).

By comparison,, an Oakland-based search engine founded in the dot-com boom, has 200 employees in a 79,000-square-foot (7,339-sq.-m.) office it shares with other companies owned by parent IAC Publishing, spokeswoman Suraya Akbarzad said.

Sungevity, a solar design company that has raised close to $900 million from investors, occupies approximately 68,000 square feet (6,317 sq. m.) in Oakland, spokesman John Ordona said.

In San Francisco, Uber partnered with a real estate firm to purchase land for $125 million and develop a 423,000-square-foot (39,298-sq.-m.) campus that will house between 3,000 and 4,000 employees. That space is in addition to Uber’s 500,000-square-foot (46,452-sq.-m.) headquarters in downtown San Francisco, according to BuildZoom.

Other highly valued, fast-growing tech companies don’t come close. Lyft said it has 66,000 square feet (6,132 sq m.)while online accommodations company Airbnb said it occupies 169,000 square feet (15,700 sq m.) in San Francisco.
