Council members voted last night for three resolutions that clear the way for construction of the $1 billion, 68,500-seat arena in the heart of Silicon Valley.
Building will begin in July, about six months ahead of plan, allowing the 49ers to move a season earlier than expected.
National Football League owners approved a $200 million loan this month that will help cover construction costs.
In December, the Santa Clara Stadium Authority unanimously approved an $850 million construction loan for the stadium. Santa Clara voters approved a ballot measure in June 2010 that authorized the city to lease land for a stadium next to the Great America amusement park.
The 49ers play their home games at 51-year-old Candlestick Park, where power failures led to two delays of a Monday Night Football game against the Pittsburgh Steelers in December. Santa Clara is about 45 miles south of San Francisco.
