Hi Ruth - I don't think that such a thing exists. The closest I have seen is the free map given out at the town hall, which has the main streets on it but not all the small ones leading off them. Google doesn't even have all the streets on their map pages, but if you go to the satellite view you can see a lot more of the buildings.
Even San Jose's maps won't be accurate as they didn't build everything on the initial plans.
Give it another 10 years and the map makers might get round to it!
