For Santa Rosa or any other city, I recommend that you use Google Maps to get started. A list is useful, but not as good as a map that shows you neighborhood names and where they are. Google isn't all-knowing, however, and they have missed some areas. I think the Santa Rosa Press Democrat has a good roundup on the web site I reference below. They (and the local MLS) divide the city into four quadrants bounded by Highway 12 and Highway 101. Within each of those quadrants are multiple neighborhoods. Just as an examples the northwest section has the JC area, Fountaingrove, and Rincon Valley. Each of those is distinct in character of the homes. There's not enough room here to do a full description, so visit the PD site to get more detail.
