What the disclosure stack holds
Insurance is priced off mapping, not off price per foot. The Hayward Fault runs along the Rockridge hill base, and the bungalows carry brick foundation and knob-and-tube disclosures. The 2020 LNU Lightning Complex destroyed homes in Pleasants Valley. Lower Rockridge below Broadway is not WUI. Pull the parcel's own mapping — CAL FIRE severity zone, FEMA flood panel, CGS liquefaction zone — and get a written quote before the contingency date.
Choosing between them
Rockridge works when walkability and rail both have to be satisfied on one parcel. Vacaville fits an acreage or 3,500-plus square foot requirement under $1.4M. Write the requirement down before the search: these two answer different ones.
