In SoCal it doesnt look like WeWork leases the entire building, just a few floors. I can't imagine there is a huge cost differential between leasing one floor of a building and leasing 3 floors (assuming the building is at least double that size). For the landlord there may be some advantages to not filling your building with one client.
