In-N-Out Burger, the iconic California eatery, is increasingly at war with health officials over COVID-19 rules.

Earlier this month, San Francisco's only In-N-Out was forced to temporarily close for violating a local rule requiring proof of vaccination for indoor customers.

Located on Fisherman's Wharf, the restaurant has since reopened for outdoor dining only.

This week, Contra Costa Health Services confirmed that an In-N-Out in Pleasant Hill was also forced to close after repeatedly violating county COVID-19 rules.

Officials said they gave the restaurant ample opportunities to comply but that it created a public health hazard by "repeatedly violating" the county order.

That order, in effect since Sept. 22, requires restaurants and some other indoor establishments to verify that all customers 12 or older are fully vaccinated against COVID-19 or have had a negative coronavirus test within the previous 72 hours.
