The viewer Contra Costa County publishes
Parcels around Pleasant Hill are published on the Contra Costa County parcel viewer, a viewer that needs no account. If you're looking near Orinda, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Concord, the record panel usually lists the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements covering ground around Orinda sit with the County Recorder. Long-held tracts around Concord may trace back through many deeds, so a title company earns its fee before a purchase.
City limits and county records
Walnut Creek lies within Contra Costa County, California, so its parcels are on the county's map. Closer to Orinda, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the city limits out by Orinda generally follows county rules rather than the town's.
What the owner name means
If a company owns land near Moraga, the state registry names who receives mail for it. "Estate of" on a record near Moraga usually means title hasn't passed yet after a death, so the personal representative is the contact.

Taking the map into the field
