If you have a specific use in mind for land near Biggs, check the Oroville zoning map before anything else: a district label decides setbacks, lot size and uses. What this Oroville guide covers: which office sets the rules for a lot, matching a lot to its zoning district, and the questions that save a wasted trip.
Reading the Oroville zoning map for one lot
Within municipal limits, zoning usually comes from the municipality, so property inside the town follows that code, at least around Paradise. Outside those limits, near Biggs or Gridley, the county may have its own zoning, or none at all; ask the county planning office to be sure. To find out which side of the line a parcel is on: check the municipal limits layer on the Butte County parcel viewer.
Opening the official parcel viewer
Begin with the Butte County parcel viewer; it covers every assessed parcel in the county, Gridley included. If you're looking near Paradise, type a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near Chico, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.

Oroville, CA: the basics
Oroville is part of Butte County, California, which means parcel data comes from the county. Oroville is also the county seat, so deeds and plats are filed in town. For acreage around Gridley, 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 Gridley generally follows county rules rather than the town's.
Calling planning staff
When you call about land near Gridley, give the parcel number and your intended use; staff can point to the right section of the ordinance. Also ask whether the lot near Gridley is a legal lot of record, because nonconforming lots can carry limits.

Features like Butte Sink National Wildlife Refuge are easy to spot when you zoom out from Biggs.
Matching a lot to the Oroville zoning map
Some planning offices post the town zoning map as a PDF; staff can confirm the district if you send the parcel ID, at least around Gridley. Near Chico, district codes like R-1, C-2 or A-1 point to a table of rules in the ordinance; the letters vary from place to place.
Setbacks, lot size and uses
In and around Chico, the ordinance spells out uses allowed by right, uses needing a permit, and uses not allowed. If the land is near Biggs, overlay districts, such as floodplain, historic or airport zones, can add rules on top of the base district.
A word on accuracy
Listed acreage is an estimate; just a licensed surveyor can set the real corners for a parcel near Chico. For acreage around Biggs, records update in batches, so a deed recorded last month can take weeks to appear.
Zoning is only step one
Even when zoning allows a use near Gridley, a building permit is a separate step; septic or sewer and driveway access are often reviewed too.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Biggs, but coverage can be spotty out of town. A saved image of the lot near Gridley and its lines keeps working without signal.
Asking for an exception
If a lot in Oroville is zoned for something else, staff can explain which process fits.
The paper trail behind a parcel
When the details count, get the recorded deed through the County Recorder; the parcel map near Paradise only summarizes it. On ground around Biggs, have ready the book and page shown in the record panel and the lookup takes minutes.
