Airbnb’s is intensifying its campaign to change San Francisco housing rules.

The home-sharing start-up introduced a new lobbying effort this week, aiming to change how San Francisco regulators treat local housing laws. The initiative, Fair to Share San Francisco, is being pushed by a coalition of local home-sharing advocate groups, including Airbnb, Peers and Home Sharers of San Francisco. They have banded together to push for housing laws that would allow residents to rent out their homes without fear of retribution from local government agencies.

“Unfortunately, the laws governing home sharing today are outdated,” the group said on its website. “It’s time for new, fair laws that enable San Franciscans to share the home in which they live.”

San Francisco residents are not allowed to sublease their apartments and houses for fewer than 30 days. Airbnb, however, is frequently used for short-term home sharing in the city.

Airbnb, which is now valued at more than $10 billion, has faced several regulatory hurdles as its service has exploded in popularity. The New York State attorney general, for example, is looking into whether some hosts are breaking local law. In May, the company agreed to hand over some data about hosts in New York City, in a deal reached with the attorney general.

In San Francisco, David Chiu, president of the San Francisco Board of Supervisors, introduced legislation in April that would allow residents to sublet their houses for short periods up to 90 days out of the calendar year. Another group, formed by affordable housing advocates who fear Airbnb’s rentals may undermine long-term rent control laws for San Franciscans, introduced a more strict initiative, but withdrew it last month.

The “Fair to Share” campaign urges local proponents of home sharing to sign a petition to change local housing laws, as well as enlist in “action teams” to spread the word.
