CDP
Sierraville
Sierraville is a community name the Census tracks. It helps you name the place, but it usually is not city hall. Start with the county layer unless an official local district says otherwise.
Starting point
Start with the county unless an official district says otherwise.
A Census-designated place is a useful local name, but it usually does not have its own city hall. For permits, records, taxes, courts, and many services, begin with the county layer.
Special districts, utilities, schools, fire agencies, parks, water agencies, coastal rules, and state maps can still control a specific issue.

Treat this as a community name.
A CDP can be real and useful on the ground, but it normally does not mean there is a city hall for permits, rent rules, business licenses, or local code.
Start with the county.
Sierra County is the county layer shown in the Census place-county reference data.
Watch for districts.
Water, sewer, fire, school, parks, utilities, coast, wildfire, and special taxes can still belong to a district or state agency.
