The viewer Contra Costa County publishes
Your first stop is the Contra Costa County parcel viewer; it includes each assessed parcel around San Pablo and Martinez. If the land is near San Pablo, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near San Pablo, the parcel card usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near San Pablo, but coverage can be spotty out of town. A printout of the tract near Hercules keeps working without signal.
Looking around the parcel
Look at adjoining lots near Hercules for context on nearby owners and uses; it helps with access and boundary questions.
Where Richmond fits in
Richmond lies within Contra Costa County, California, and the county assessor maps its lots. For a tract near El Cerrito, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the town limits toward Martinez usually follows county rules rather than the town's.

A word on accuracy
Acreage on the record is an assessed number; just a licensed surveyor establishes the real boundary on land around Martinez. For a tract near Orinda, owner names and values update on a schedule, so a deed recorded last month might lag behind.
How land is described here
California follows the Public Land Survey System, so deeds around San Pablo reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Martinez can be irregular. Keep the legal description for land near Orinda for any title or survey request.
Reading the owner field
When a business holds title near Martinez, the state registry names who receives mail for it. "Estate of" on a record near Pinole usually means title hasn't passed yet after a death, and the executor handles questions.
Values and taxes
The record for a parcel near San Pablo often lists value and tax amounts; questions about value go to the County Assessor.
Recorded documents worth pulling
For anything that matters, get the recorded deed from the County Recorder; the parcel line is a drawing of it, which applies near Martinez as much as anywhere. Long-held tracts near Orinda can go back through a long string of deeds, and a title company can sort it out on a real sale.
Which office to call
If the acreage or value on a parcel near El Cerrito looks off are handled by the County Assessor, since that office keeps the assessment data. Questions about what you can build around San Pablo need the planning or permitting office, depending on whether the land is inside town limits.
