I can see where in some cases the legal intricacies of city limits, unincorporated areas, etc. might play a role in the discussion. However, I STRONGLY suspect that, as a private university and under California law, Stanford has the right to control this issue on anything that is its property, regardless of technical location, as long as it doesn’t contradict codified law. In other words, Stanford has the right to be dry, for example, even if the rest of the county and state is not. Just like any person has the right to forbid alcohol from their homes. So let’s not get bogged down in postal codes and city limits.
