Running a Concord property search step by step
Open the Contra Costa County parcel viewer to start; addresses, names and parcel numbers all work.
Pulling up a parcel
Go first to the Contra Costa County parcel viewer; it maps each tax parcel in the county, Clayton included. Near Pittsburg, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Lafayette, the record panel usually lists the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Taxes on the record
Many records show assessed value and taxes for land near Martinez; the County Assessor sets values and the treasurer or collector bills taxes.
Reading the legal description
California follows the Public Land Survey System, so rural legal descriptions near Martinez 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 Lafayette can be irregular. Copy the legal description from the record for the parcel near Walnut Creek before you request a deed or survey.
Recorded documents worth pulling
For anything that matters, pull the recorded deed through the County Recorder; the parcel map near Pleasant Hill only summarizes it. Long-held tracts near Lafayette may go back through many deeds, so a title company can sort it out on a real sale.
City limits and county records
Concord lies within Contra Costa County, California, so its parcels are on the county's map. Out toward Lafayette, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the town limits toward Clayton often follows county rules, not municipal ones.
Places you'll see on the map
Martinez is the county seat, which is where the courthouse records live. Smaller places on the map include Pleasant Hill, Clayton, and Walnut Creek, where town lots give way to larger tracts. Around 1,155,025 people live in Contra Costa County (Census Bureau estimate, 2023) across about 717 square miles. Places such as Clayton-Marsh Creek-Greenville Fault, San Pablo Dam Reservoir, and Mount Diablo State Park help you orient on the aerial around Martinez.
Who handles what
Recorded documents for a parcel near Martinez come from the County Recorder, usually searchable by name or document number. Building or septic questions for a lot near Walnut Creek go to planning, building or health offices, depending on whether the land is inside town limits.
Trusts, estates and LLCs
If a company owns land near Pittsburg, look it up in the state's business registry. An estate listed as owner near Martinez usually means title hasn't passed yet after a death, and the executor handles questions.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Pleasant Hill, but coverage can be spotty out of town. A saved image of the lot near Martinez and its lines helps when you meet an owner or agent.
Confirming with the deed
Bring the document number shown for the parcel near Pittsburg so the lookup is fast; hire a title company before money changes hands.
Making contact
A short letter to the mailing address on the record gets more replies than a cold call for property around Clayton.
A word on accuracy
Tax maps are drawn for assessment, not measured on the ground, so a fence near Clayton can sit several feet off the line on screen. Records update in batches, so a fresh transfer around Pleasant Hill might lag behind.
Context from nearby lots
Click the parcels around the one near Walnut Creek to see who owns the neighboring land; that's handy for easements and access.
When a parcel crosses a boundary
Contra Costa County borders Alameda County, Marin County, Sacramento County, San Francisco County, and San Joaquin County; every one of them runs a separate parcel map. Acreage along the edge near Pleasant Hill can show up across two assessors' files, so look at the neighboring map as well. For acreage around Pittsburg, our state page links every bordering county map across California.
