A Lassen County plat map is the quickest way to see who owns a tract, how big it is and where its lines run before you drive out to look. Lassen County in California publishes that information for free.
We'll start with the official link, then cover Bieber and the other towns, land types, property lines and records.
What the map covers, from Susanville to the back roads
Susanville serves as the county seat. The map also labels unincorporated places, Bieber, Clear Creek, and Doyle among them. Roughly 28,861 people (Census Bureau, 2023) share Lassen County's 4,541 square miles of land. Click anywhere between Susanville and Bieber and you are likely to land on a big ranch, farm or timber parcel rather than a house lot. On the parcel layer, Lassen Volcanic National Park and Lassen National Forest show up as public ground, and the private tracts along their edges are worth checking line by line.
Work and land use in Lassen County
Census business counts for 2022 list 396 establishments in Lassen County; retail trade tops the list, with health care and social assistance and construction close behind. Compared with the nation, the county has an unusually high share of businesses in forestry and logging, utilities, and accommodation (hotels, motels, RV parks and camps). Timber tracts in Lassen County change hands for wood value as much as for building, so check the parcel record and the aerial photo together. Keep that in mind when you compare parcels in Lassen County: who works here shapes what land sells.
Getting into the Lassen County ArcGIS parcel map
Parcels from Bieber to Janesville are on the Lassen County ArcGIS parcel map, which the county runs on an Esri ArcGIS web map. Rural tracts in Lassen County often have no street address, so try an owner search or simply pan to the area and click. If the map ever goes missing, check the Lassen County, California listing on Platbookmapper for the new address.
Private and public hunting ground in Lassen County
Hunters working the country toward the Shasta County line can use the parcel map to put a name on every woodlot and field. Around Lassen Volcanic National Park and Lassen National Forest, private tracts can press right up against the public boundary, so check the lines before you walk in. For licenses, seasons and public hunting land, go to the California Department of Fish and Wildlife. Landowners in Lassen County hear from a lot of hunters; a specific request that names the parcel stands out.
Who uses the Lassen County parcel map
The same map serves very different jobs around Susanville. Turkey hunters near Clear Creek use the map in spring to confirm which fields their permission actually covers. A buyer who wants ten or twenty acres near Bieber can rule out most of the wrong tracts from a desk before driving out. Owners in Susanville compare their assessment with similar lots on the same street. If a listing in Bieber says the yard backs up to open land, the map shows who owns that land.
What the Lassen County plat map shows about lot lines
Zoom in far enough on a lot in Susanville and you may notice lines crossing driveways or splitting sheds, a normal quirk of tax mapping. Because California is a section-township-range state, the legal description of a rural tract in Lassen County reads like a grid reference that you can match to the section lines on the map. Planning a fence or shed on a lot in Susanville? Have a California licensed surveyor mark the corners first.
Behind the map: land records in Lassen County
Every line on the Lassen County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. Names differ across states, so confirm on the official Lassen County site which office records deeds and plats. The parcel record often lists a deed book and page or an instrument number, which is how you request a copy of the recorded deed for a tract near Susanville.
Near the county line
Lassen County shares borders with Modoc County, Plumas County, Shasta County, Sierra County, and Washoe County, NV, and each one runs its own parcel map and recording office. All of them are listed on our California page.

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.
