Running an Oakley property search step by step
When land near Pittsburg has no street number, click the parcel on the aerial.
Where the parcel data lives
Your first stop is the Contra Costa County parcel viewer; it maps every assessed parcel from Antioch to Danville. When a rural tract has no street number, zoom in from Brentwood until the lines appear, then click inside the one you want. For acreage around Clayton, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
Sections, lots and bearings
California follows the Public Land Survey System, so deeds around Brentwood reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Brentwood can be irregular. Write down the legal description for the tract near Pittsburg before you request a deed or survey.
Offices that can help
If the acreage or value on a parcel near Concord looks off are handled by the County Assessor, which maintains the tax roll. Building or septic questions for a lot near Antioch need the planning or permitting office, town or county, depending on location.
Oakley and the county around it
Oakley sits in Contra Costa County, California, so its parcels are on the county's map. Local government in Oakley handles things like zoning, permits and utilities inside its limits, while the county keeps the tax map. Lots just outside the city limits toward Danville generally falls under county rules rather than the town's.
Looking around the parcel
Click the parcels around the one near Pittsburg to see who owns the neighboring land; it helps with access and boundary questions.
Before you lean on the lines
The acreage figure is a tax-roll number; just a licensed surveyor can set the real boundary for a parcel near Concord. For a home near Brentwood, records update in batches, so a deed recorded last month might lag behind.
Tax data in the record
The record for a parcel near Pittsburg often lists value and tax amounts; questions about value go to the County Assessor.

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 Pittsburg can show up in two county records, so look at the neighboring map before you assume the acreage. For a parcel near Antioch, the Platbookmapper state page links every neighboring county map across California.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Pittsburg, but coverage can be spotty out of town. A printout of the tract near Antioch helps when you meet an owner or agent.
Trusts, estates and LLCs
Near Danville, the owner field shows who the tax bill names, which may be a person, a trust, a company or an estate. An estate listed as owner near Pittsburg usually means title hasn't passed yet after a death, so the personal representative is the contact.
Proof of ownership
With a lot near Danville, a viewer entry isn't legal proof; the recorded deed at the County Recorder is.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
