The County of San Diego Assessor/Recorder/County Clerk branch office in Chula Vista processes property assessments, document recording, and vital records from 590 Third Avenue in the 91910 civic campus. This South County satellite handles birth, death, and marriage certificates, fictitious-business-name filings, and real-property deed recordings, consolidating services that residents otherwise access at the downtown San Diego headquarters or through appointments coordinated by City of Chula Vista - City Hall on Fourth Avenue. Marriage licenses require advance appointment scheduling through the Recorder/Clerk division, with both parties presenting valid identification at the Third Avenue counter. Document-recording services accept grant deeds, deeds of trust, reconveyances, and liens under California Government Code Sections 27201 and 27289, requiring notarized acknowledgment and legible notary seals for microfilm reproduction. The branch sits within the same Third Avenue government corridor that houses Superior Court South County Division at 500 Third Avenue, concentrating county and judicial functions within a two-block radius of the E Street trolley station. Assessor staff process supplemental and change-in-ownership reassessments under California Revenue and Taxation Code Section 11911.1, requiring Assessor's Parcel Numbers on all recorded deeds affecting San Diego County properties.
