The move comes amid persistent questions about how to enforce the health measure, which backers say will protect performers in the multibillion-dollar porn industry from contracting HIV and other diseases.
Producers complain the sight of a condom in a sex scene turns off consumers of their videos.
The Los Angeles City Council voted 9-1 on Tuesday to give final approval to the measure, proposed after the AIDS Healthcare Foundation qualified an initiative for the ballot that would have asked voters in June to mandate condoms at porn shoots as a condition of obtaining a film permit.
The city would have had to spend over $4 million to hold the election, and city officials said a decision to simply adopt the condom requirement allowed them to dodge that costly election.
The council gave preliminary approval to the measure last week, and its passage made the city the first in the nation to impose such a requirement. Most of the U.S. porn industry is based in Los Angeles.
The California Division of Occupational Safety and Health (Cal-OSHA) already requires porn performers to wear barriers, such as condoms, when they are in contact with bodily fluids.
But enforcement has been a challenge for the state. For one, the Cal-OSHA requirement is not specifically aimed at adult films, and it is openly violated within the industry, said Michael Weinstein, president of AIDS Healthcare. He has clashed with porn producers for years over the issue.
"I don't know of any other industry where people go out in public and say they're not going to follow the law," Weinstein, whose group provides care to AIDS patients, said last week.
