Plenty of people leave their bikes outside. I agree with habernac, if it is decent, I wouldn't. Best to have the crappiest bike on the rack. From keeping an eye on stolen bike threads, it seams most that go missing occur after 5:00 if they are left on racks outside.
If your building doesn't have indoor parking, maybe try one of the city lots?
