End of an era? Maybe. Hilton & Hyland's sign has come off the Standard Oil building in Beverly Hills, with the high-end brokerage beginning a move to smaller offices within the city. The relocation comes after the company's soon-to-be former landlord, Standard Oil Investment Group, took the brokerage to court over more than $650,000 in back rent and over $65,000 in late fees before asking a judge to toss the complaint last month.
