When land near Hercules catches your eye, a look at the Pinole GIS map gives you lines, owner names and parcel numbers. This Pinole guide covers: where that map lives, how to search it, and the limits worth knowing.
Opening the Pinole GIS map: start here
For land near El Cerrito, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Getting to the right map
Lots and tracts near Richmond appear on the Contra Costa County parcel viewer, free to use and open without a login. Closer to Hercules, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. Closer to Richmond, the parcel card usually lists the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Offices that can help
Recorded documents for a parcel near San Pablo sit in the index kept by the County Recorder, usually searchable by name or document number. Zoning, permits and septic questions near Richmond go to planning, building or health offices, depending on whether the land is inside town limits.
Recorded documents worth pulling
Before you sign anything, pull the recorded deed through the County Recorder; the parcel map near San Pablo only summarizes it. Near El Cerrito, have ready the document number shown in the record panel so staff can find the deed fast.
How land is described here
California follows the Public Land Survey System, so rural legal descriptions near San Pablo cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near San Pablo odd-sized. Keep the legal description for land near San Pablo when you talk to a surveyor.
Pinole, CA: the basics
Pinole sits in Contra Costa County, California, so its parcels are on the county's map. For a home near Richmond, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the city limits toward Hercules usually follows county rules instead.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near El Cerrito, but coverage can be spotty out of town. A saved image of the lot near Richmond and its lines keeps working without signal.
Three ways to find a parcel
Addresses are the easiest route inside Pinole; owner names are usually entered last name first. Out toward Hercules, searching by parcel number never misses, and you'll find it on tax statements.
Saving what you find
Save a screenshot of the lot near El Cerrito and its record panel, so you have it when calling an office.
A word on accuracy
The acreage figure is a tax-roll number; just a licensed surveyor can set the real boundary on land around Orinda. Closer to San Pablo, records update in batches, so a deed recorded last month can take weeks to appear.
Troubleshooting the viewer
If the viewer stalls on a phone near Richmond, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
When a parcel crosses a boundary
Contra Costa County touches Alameda County, Marin County, Sacramento County, San Francisco County, and San Joaquin County, all with their own assessor records.

For acreage around El Cerrito, the Platbookmapper state page lists every bordering county map for California.
