The Federal Communications Commission has voted to reverse a stringent merger requirement on Charter Communications Inc. CHTR, +1.20% that would have compelled the company to build out internet service to one million households already being served by a competitor, FCC officials said.

The vote overturns one of the toughest conditions that the FCC, under the Obama administration, had imposed on Charter’s roughly $60 billion deal to buy Time Warner Cable and Bright House Networks last year. The condition at the time had called for Charter to build out high-speed internet access to a total of two million homes, with half already being served by a broadband provider like other cable companies.
