I don't think that's quite right -- I think you're thinking of 1601 S. California Ave. Faceboook had there and 1050 Page Mill, but not 1501 Page Mill afaik -- that was HP/HPE until recently and is still an office building, now leased by Tesla.

After Facebook moved out of 1601 California Ave. in 2011, it was leased to Theranos. Then it (and some of the buildings on adjacent parcels) got knocked down to turn it into a Stanford faculty housing development that opened in 2017-2019 (University Terrace). I think that's the only housing in the Stanford Research Park.
