The San Diego County Assessor/Recorder/County Clerk's Chula Vista branch at 590 Third Avenue in Chula Vista's Third Avenue Village issues marriage licenses, performs civil wedding ceremonies, and processes vital-record requests for birth, death, and marriage certificates. Couples choosing a county-officiated ceremony use the branch's dedicated wedding room and adjoining patio, a setting that complements the larger reception venues available at South Bay locations such as Casa Sur Hacienda. A non-confidential marriage license costs $70 and a confidential license costs $89, with an additional $88 ceremony fee when performed by county staff and $18 per witness provided by the office. No blood test or waiting period is required under California Family Code Section 350, and both parties must be at least 18 years old — applicants under 18 must first obtain authorization through the Juvenile Court. The Chula Vista branch also records real-property documents, files fictitious business name statements, and maintains assessment records — the same property-valuation data referenced by enrolled agents at B&U taxes and more during annual filing and appeal cycles. Marriage licenses require an appointment, while certified copies of previously registered marriage certificates are available on a walk-in basis with processing verified against county indices dating to San Diego County's 1850 incorporation.
