Parking lots near Yankee Stadium are charging fans who drive to playoff games $50 to park and, and some attendants are offering to find room to park cars for up to three times the going rate when the lots are apparently full, a City Council Member of Queens, Hiram Monserrate, said.

Mr. Monserrate is calling for the city’s Department of Consumer Affairs to investigate the parking operators after he said two parking attendants from Central Parking Co. offered to park his car for $150 on Sunday, even though a sign on the lot indicated that it was full.

Mr. Monserrate said other people attending the game told him that the practice is a regular occurrence during the playoffs.

He said he’s been told that the price is closer to $30 during regular season games.

“That’s something new to me,” he said. “Because I haven’t been to Yankee Stadium for a while, it took me aback. Clearly, there is a need for some monitoring.”

A spokeswoman for the Yankees, Alice McGillion, declined to comment, saying in an e-mail message that the team does not run or control the parking lots in any way.
