Before you buy a lot near Biggs with a plan in mind, look at the Chico zoning map first: the zoning district can make or break the plan. What this city guide covers: who controls zoning for a given parcel, matching a lot to its zoning district, and the questions that save a wasted trip for land near Biggs.
Getting started with the Chico zoning map
Within municipal limits, the local government adopts its own zoning map, which means a parcel in Chico answers to that map. Past the city line, around Paradise, the county may have its own zoning, or none at all; confirm with the county office. A fast way to settle it: look for a city limits layer in the Butte County parcel viewer.
The free map to start with
Go first to the Butte County parcel viewer; it covers every tax parcel in the county, Biggs included. With a lot near Gridley, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. Out toward Gridley, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Field tips

Zoning is only step one

Places you'll see on the map

City limits and county records

Reading the district label
