In Lake Tahoe, a one-room courthouse will cost taxpayers $747 a square foot. In Alpine County, the state recently canceled plans to spend $21,666 per resident to build a one-room courthouse."When you're looking at the cost per square foot, that's essentially the same as it is for a beachfront home; it's just offensive," Assemblyman Nathan Fletcher said.Fletcher has been highly critical of those running state courts and how they spend taxpayer money.
