When land near Biggs catches your eye, the Oroville GIS map shows lines, owner names and parcel numbers. This Oroville guide covers: where that map lives, how to search it, and what to double-check with records.
Opening the Oroville GIS map
If you're looking near Biggs, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Opening the official parcel viewer
Begin with the Butte County parcel viewer; it includes every assessed parcel from Biggs to Paradise. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, and that holds around Paradise too. In and around Gridley, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
A word on accuracy
Listed acreage is a tax-roll number; just a licensed surveyor sets the real corners for a parcel near Paradise. For a tract near Gridley, records update in batches, so a deed recorded last month might lag behind.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Biggs, though signal can drop in rural spots. A saved image of the lot near Biggs and its lines helps when you meet an owner or agent.
Oroville, CA: the basics
Oroville sits in Butte County, California, which means parcel data comes from the county. As the county seat, Oroville hosts the courthouse, which puts the County Recorder close by. For property near Gridley, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the city limits out by Paradise often answers to county rules rather than the town's.
Finding the right lot
For a house in Oroville, search the street address; owner names are usually entered last name first. If the land is near Chico, searching by parcel number never misses, and it carries over to every office in the county.
How land is described here
California is laid out under the Public Land Survey System, which means a tract near Paradise is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Biggs can be irregular. Copy the legal description from the record for the parcel near Gridley when you talk to a surveyor.
Beyond the parcel lines
Closer to Biggs, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
When a parcel crosses a boundary
Butte County borders Colusa County, Glenn County, Plumas County, Sutter County, and Tehama County, and each of those keeps its own parcel map. A tract near the line by Gridley may show up across two assessors' files, so look at the adjacent map before you assume the acreage.
