In-N-Out is closing its corporate office in Irvine, the Los Angeles Times reported. It will move employees back to Baldwin Park, the city where the first In-N-Out drive-thru opened in 1948.

In-N-Out has maintained offices in Irvine since 1994. Property records indicate In-N-Out corporate owns the building at 4199 Campus Drive that houses its OC corporate headquarters and has owned it since the early 1990s.

Company founder Harry Snyder established an office a mile away from the original In-N-Out store at Francisquito and Garvey avenues in Baldwin Park.

The Irvine offices are scheduled to close by 2029. Some workers will move to Baldwin Park, but others will head to Tennessee, where the company is building a new 100K SF corporate office in Franklin that is expected to serve as an eastern corporate hub for the burger chain.

The new building will open next year, which is also when In-N-Out is scheduled to open its first restaurant in Tennessee, WKRN.com reported. The company's owner and President Lynsi Snyder-Ellingson told Tennessee business leaders earlier this month that she is considering opening as many as 35 locations in the state, the Business Journals reported.

It will be the burger purveyor's first move east of Texas. It expanded into the state in 2011 and now has more than 40 locations there, according to its website.
