Tehama County Government: Structure, Services, and Demographics

Tehama County occupies a position in the northern Sacramento Valley of California, bordered by Shasta, Plumas, Glenn, Butte, and Trinity counties. The county seat is Red Bluff. This page covers the administrative structure of Tehama County government, the services it delivers to residents, its demographic profile, and how its governance compares to broader patterns in California county government structure.

Definition and scope

Tehama County is a general law county in California, meaning its governance structure is defined by the California Government Code rather than a locally adopted county charter. As of the 2020 U.S. Census, the county population was 65,084 (U.S. Census Bureau, 2020 Decennial Census). The county spans approximately 2,951 square miles, making it geographically expansive relative to its population density — roughly 22 persons per square mile.

The county government exercises authority over unincorporated areas and provides mandated services across the entire county, including incorporated cities such as Red Bluff (the county seat) and Corning. City governments within Tehama County operate as separate municipal entities under California law and are not subordinate to the Board of Supervisors for their internal governance.

Scope and coverage: This page addresses the county-level government of Tehama County under California state law. Federal agency operations, tribal government jurisdictions (including the Paskenta Band of Nomlaki Indians and the Mooretown Rancheria, which has land interests in the region), and the independent city governments of Red Bluff and Corning fall outside this page's coverage. State agency programs administered locally are referenced where they intersect with county services but are governed by state statute, not county ordinance.

How it works

Tehama County government operates under a Board of Supervisors comprising 5 elected members, each representing a geographic district. Supervisors serve 4-year staggered terms. The Board holds legislative and executive authority over county operations, adopts the annual budget, sets policy, and appoints the County Administrative Officer (CAO), who manages day-to-day department operations.

Key elected county offices outside the Board include:

  1. Sheriff-Coroner — law enforcement and coroner functions for unincorporated areas and contracted services to incorporated cities
  2. District Attorney — prosecution of criminal cases within the county
  3. Assessor-Recorder — property valuation, recording of legal documents, and maintenance of official records
  4. Treasurer-Tax Collector — investment of county funds and collection of property taxes
  5. Auditor-Controller — financial oversight, payroll, and internal audit functions
  6. Clerk of the Board / County Clerk — elections administration and Board of Supervisors recordkeeping

Department heads for health, social services, planning, and public works are appointed rather than elected, operating under the CAO structure with Board oversight.

Property tax administration in Tehama County operates under the constraints established by California Proposition 13, which caps assessed value increases at 2% annually absent a change in ownership or new construction, and sets the base property tax rate at 1% of assessed value.

The county maintains a Superior Court under the California trial court system, which is state-funded and administered separately from county government under the Trial Court Funding Act of 1997 (California Courts).

Common scenarios

Residents and businesses interact with Tehama County government across a defined set of service categories:

Decision boundaries

Tehama County government's authority is bounded by several distinct jurisdictional lines:

County vs. State authority: The county administers many programs as a state agent — welfare, public health, elections — rather than as an autonomous policymaker. State mandates from Sacramento override county preferences in these domains. The California Department of Finance exercises fiscal oversight over county budget practices through state subvention controls.

County vs. City authority: The cities of Red Bluff and Corning operate under their own city councils with independent land use, police, and municipal finance authority within their boundaries. The Board of Supervisors has no land use jurisdiction within city limits.

General law vs. charter counties: As a general law county, Tehama cannot adopt ordinances that conflict with state law, unlike charter counties such as San Francisco or Los Angeles, which have limited home rule authority. This distinction directly limits local policy flexibility.

Environmental jurisdiction: The Tehama County Air Pollution Control District operates with independent board authority on air quality matters. State oversight from the California Air Resources Board sets minimum standards that the local district must meet or exceed.
