Mitt Romney's attempt for voters not to think his wealth makes him out of touch may face another challenge, as a new report from Politico Tuesday reveals his family is building elevators for their four cars in a renovation of their California beach house.

The renovation comes from a 2008 plan that is on file with the city of San Diego. The documents show Romney paid $21,500 to attorney Matthew A. Peterson to lobby city officials for approval of the home's construction. Romney also paid a local architecture firm $1,000 in 2010 to lobby officials.

In addition to the car elevator, the renovation of the 76-year-old home also would include an outdoor shower and a 3,600 square foot basement. The U.S. Secret Service asked Politico not to release the specific designs of the renovation for security purposes.

The San Diego beach house is one of three homes Romney owns, which also include a New Hampshire lake house and a condominium in Belmont, Massachusetts.
