Dozens of affordable housing groups and community organizations that have long accused Airbnb of exacerbating housing shortages are taking their grievances to U.S. financial regulators just as the short-term rental giant prepares to go public.

In a letter to the U.S. Securities and Exchange Commission viewed by The Information, the groups complain that Airbnb hasn’t complied with rules limiting short-term rentals in many cities. They contend that Airbnb should be required to disclose more information to investors about how many rentals on its site are run by professional property managers. The groups claim these managers are siphoning apartments from residential housing markets in Paris, New York and other big cities.
