After months of fevered lobbying and bitter debate, the Chicago City Council passed a groundbreaking ordinance yesterday requiring “big box” stores, like Wal-Mart and Home Depot, to pay a minimum wage of $10 an hour by 2010, along with at least $3 an hour worth of benefits.

The ordinance, imposing the requirement on stores that occupy more than 90,000 square feet and are part of companies grossing more than $1 billion annually, would be the first in the country to single out large retailers for wage rules.

A gallery packed with supporters of the bill broke into cheers as the measure passed, by a vote of 35 to 14, after four hours of intense speeches and debate.

“This is a great day for the working men and women of Chicago,” said Alderman Joseph A. Moore, the measure’s chief sponsor. Mr. Moore said he had had inquiries about the ordinance from officials in several other cities.
