changing Zoning in San Jose, Ca

[Sean Carroll]

Does anyone have any experience with changing the zoning on a building? Specifically, I have a lead in downtown San Jose, the building has been vacant for a long time and it is zoned as a commercial for a nursing home and I would like to change it to a multi-family residential (3 plex). I have been on hold with the building department for an hour now and thought I might have better luck on here. My questions are...

What do I need to do?

What does the process entail?

How much does this cost?

how long does it take?
