A couple of days ago Contra Costa County passed an emergency ordinance to issue fines for Health Order Violations. Read the ordinance here. Check out all the health orders here.
From the PR:
For health order violations involving non-commercial activities, the amount of the fine is $100 for a first violation, $200 for a second violation, and $500 for each additional violation within one year of the initial violation. For violations involving commercial activity, the amount of the fine is $250 for a first violation, $500 for a second violation, and $1,000 for each additional violation within one year of the initial violation. If a violation continues for more than one day, each day is a separate violation.
