The CalRoster labels county entries elected and appointed officials and does not publish a selection method for each individual role. The source compiler therefore does not infer elected or appointed status from the title alone. The Secretary of State notes that each local jurisdiction supplies its own roster data; this is a dated public record, not a live officeholder feed.

How to interpret this record

City of Clayton, CA — 2026 Public Officials

Local government is a collection of institutions with different boundaries and responsibilities. A municipality, school district and special district can serve overlapping places without being the same organization.

Map the institution, not just the city name

A mailing address can sit inside several governmental boundaries. A county, municipality, school district and special-purpose body may each make different decisions. The Census of Governments provides a structured way to identify governmental units; a unit’s existence does not automatically tell you who currently holds each seat or when its next election occurs.

Distinguish a directory from a live roster

An institutional directory describes organizations. An official roster describes people connected to offices at a stated time. These sources may be published by different agencies on different schedules. Electionpedia links the institution and the person when the evidence supports a match, while preserving the distinction between the source’s reference year and the latest date the file was checked.
