Pelosi's new office is House's costliest by far.

House Speaker Nancy Pelosi has more than quadrupled the rent on her San Francisco district office, making the $18,736-a-month cost of her new South of Market space the highest in the House, according to a new report. The rent - part of Pelosi's budget, which is funded by taxpayers - is nearly double the next-highest rent in the House: Rep. Jerrold Nadler, D-N.Y., pays $10,600 a month for his Manhattan office, while representatives from Sacramento, Boston and Los Angeles pay nearly that much, the report said.Link
