Where the El Cerrito GIS map lives
In most places the county maintains the parcel layer, and for El Cerrito that means the Contra Costa County parcel viewer.
Where the parcel data lives
Go first to the Contra Costa County parcel viewer; it includes every assessed parcel around San Pablo and Pinole. Around Richmond, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. Closer to Richmond, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Saving what you find
Print or screenshot the parcel near Pinole with its ID visible, which helps later when you ask the assessor or a title company.
El Cerrito and the county around it
El Cerrito is part of Contra Costa County, California, so its parcels are on the county's map. With a lot near Hercules, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the city limits near Orinda usually answers to county rules, not municipal ones.
Which office to call
Recorded documents for a parcel near Richmond sit in the index kept by the County Recorder, sometimes only in person. Zoning, permits and septic questions near San Pablo go to planning, building or health offices, and the answer depends on jurisdiction.
Three ways to find a parcel
By address works best for lots in El Cerrito; owner search often wants the surname first. Closer to Orinda, searching by parcel number never misses, and it carries over to every office in the county.
A quick look at the area
Martinez is the county seat, home to the main records offices. You'll also find San Pablo, Richmond, Pinole, and Hercules. About 1,155,025 people live in Contra Costa County (Census estimate, 2023) across roughly 717 square miles. Landmarks such as Clayton-Marsh Creek-Greenville Fault, San Pablo Dam Reservoir, and Mount Diablo State Park are easy to spot when you zoom out from San Pablo.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near San Pablo, but coverage can be spotty out of town. A saved image of the lot near Pinole and its lines helps when you meet an owner or agent.
Beyond the parcel lines
Near Hercules, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
Recorded documents worth pulling
The map is an index, not the title: deeds, subdivision plats and easements for land near Hercules are filed with the County Recorder. Older tracts near Richmond can sit on several deeds, and a title company is worth hiring on a real sale.
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. A tract near the line by Richmond may be split in two county records, so open the adjacent map as well. For land near Richmond, the Platbookmapper state page links every neighboring county map for California.
Before you lean on the lines
Tax maps are drawn for assessment, not measured on the ground, so a fence near Orinda can sit a few yards off the line on screen. For acreage around Orinda, records update in batches, so a deed recorded last month can take weeks to appear.
What the record panel tells you
If sale dates appear, they help gauge the market near Lafayette give a rough idea of values; they're not an appraisal.
How land is described here
California is laid out under the Public Land Survey System, so rural legal descriptions near Pinole cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Richmond vary in size. Copy the legal description from the record for the parcel near Hercules when you talk to a surveyor.
Troubleshooting the viewer
When the map won't open around Richmond, try a desktop browser or clear the cache; links occasionally change, and our directory page keeps the current one.
