Comp Care Selling Irvine Building

Comprehensive Care Corp., the troubled owner of a chain of drug and alcohol treatment centers, said Friday it had agreed to sell its former corporate headquarters in Irvine for $9 million to an unidentified buyer.

Comprehensive Care said last year it would move to Missouri and sell most of its assets in California in order to pay a pressing $25-million debt. That announcement came shortly after a deal to merge with a Virginia hospital company fell through in October when the hospital’s lender backed out.

Comprehensive Care said in a statement that the sale of its two-story building at 18551 Von Karman Avenue depends on the results of a test for environmental contamination demanded by the buyer, a test not yet complete. The buyer has put down a $500,000 deposit, but the company says the sale also depends on the buyer raising the rest of the purchase price.

Comprehensive Care operates the CareUnit Hospitals for drug and alcohol treatment, among other businesses.
