Where the Pleasant Hill GIS map lives
If you're looking near Lafayette, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Where the parcel data lives
Begin with the Contra Costa County parcel viewer; it includes every tax parcel in the county, Orinda included. For acreage around Moraga, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Martinez, write down the parcel ID before closing the panel; each office in the county uses it to find the file.
Where the recorded documents are
When the details count, request the recorded deed from the County Recorder; the parcel map near Orinda only summarizes it. Inherited tracts near Lafayette can sit on several deeds, and a title company can sort it out on a real sale.
Legal descriptions in California
California is laid out under the Public Land Survey System, so rural legal descriptions near Lafayette cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Walnut Creek can be irregular. Keep the legal description for land near Martinez before you request a deed or survey.
Before you lean on the lines
Listed acreage is a tax-roll number; only a licensed surveyor sets the real boundary for a parcel near Moraga. In and around Lafayette, owner names and values update on a schedule, so a deed recorded last month might lag behind.
When a parcel crosses a boundary
Contra Costa County borders Alameda County, Marin County, Sacramento County, San Francisco County, and San Joaquin County, all with their own assessor records. Ground near Walnut Creek that runs to the line may show up across two assessors' files, so check the adjacent map as well. Out toward Lafayette, our state page links every bordering county map across California.

On ground around Orinda, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the town limits out by Martinez often falls under county rules instead.
