12052.5. The licensing authority shall give written notice to the applicant indicating if the license is approved or denied within 90 days of the initial application for a new license or a license renewal or 30 days after receipt of the applicant's criminal background check from the Department of Justice, whichever is later.
Sheriffs have 90 days to reply to your application as MOST background checks take 30 days or less. MOST Sheriffs are in violation of this law! It takes almost a year in many counties in California!
