LOS ANGELES — Eric Garcetti celebrated the start of his first term as mayor Sunday with a promise to do the basic things right while getting Los Angeles' economy rolling again.
The 42-year-old Ivy Leaguer, a veteran city councilman and son of a former prosecutor, took a ceremonial oath of office on the City Hall steps as part of inaugural festivities featuring Jimmy Kimmel and the musician Moby.
Officially, he takes over the job leading a sprawling city of nearly 4 million people on Monday.
"These times demand a back-to-basics mayor focused above all else on our economy and jobs," Garcetti said in a speech punctuated by optimism and recognition of a tough job ahead.
"We have to accept that the days of seemingly spontaneous growth in huge mega-industries are gone, maybe for good," he said.
He replaces fellow Democrat Antonio Villaraigosa, 60, who exits after two uneven terms during which he expanded rail lines in a city notoriously choked by cars and pushed to improve a school district over which the mayor has no direct control.
Garcetti sketched an agenda that included cultivating ideas with business executives and universities, stopping the flight of Hollywood productions and reducing red tape and business taxes long seen as discouraging job growth.
"You'll have a local government that's off your back and on your side," he promised.
