Airbnb plans to conduct a comprehensive review of every property listed on its platform as part of a series of initiatives to give customers “peace of mind,” Brian Chesky, the company’s chief executive, announced at the DealBook Conference in Manhattan on Wednesday. By the end of next year, Mr. Chesky said, Airbnb will check the accuracy of photographs, addresses and other information posted with each property, as well as verify that the listings meet safety standards and that the hosts are who they say they are. “We’re going to make sure we can stand behind every single listing, every single host,” he said. “We want to give peace of mind to our guests.” Mr. Chesky did not explain precisely how Airbnb would verify every listing. “We’re going to be coming back with more details,” he said. But he said the process would involve asking users whether the information in certain listings turned out to be accurate. An Airbnb spokesman said on Wednesday that the company would verify postings “using a combination of remote technology inspections and verifications from our community.”
