The house at each price

Carrying $1,600,000 in each

To Oakland City Center (12th St BART): 38 minutes by BART from Dublin, 12 by BART from Rockridge — a 26-minute edge to Rockridge, or 4.3 hours across a ten-trip week.

Fire, flood and the premium
The two carry different disclosure files, and the premium follows the file. The Dublin valley floor is not WUI. The Hayward Fault runs along the Rockridge hill base, and the bungalows carry brick foundation and knob-and-tube disclosures. Lower Rockridge below Broadway is not WUI. None of this substitutes for the parcel: check CAL FIRE zoning, the FEMA flood panel and CGS seismic hazard mapping, then price the policy in writing.
Which search this actually is
Dublin fits a five-bedroom new-construction requirement at a BART terminus. Rockridge works when walkability and rail both have to be satisfied on one parcel. The decision is which requirement is load-bearing, because neither submarket satisfies both lists.
