Many San Francisco renters, especially those living in rent-controlled units, have likely had to sign leases, or revised leases, with their landlords in recent years that specifically prohibit short-term rental of the unit through services like Airbnb. This of course makes sense from a landlord's perspective, and it provides an easy out for landlords when it comes to evicting someone for cause. As the Examiner reports, the number of Airbnb-related violations cited in eviction notices filed with the Rent Board have steadily increased over the past five years.

These for-cause evictions have cited breaches of lease agreements that usually say something like "illegal use of unit." And though only 145 evictions in the last year (out of a total of 2,120 eviction notices filed) specifically mention Airbnb as a violation, that number is probably much higher when you factor in tenants who move out after intimidation by landlords, without official eviction proceedings, and tenant buyouts after Airbnb-related eviction threats.

One lawyer says there are "hundreds of cases."

It is a fact, though, that in the last year, the Ellis Act was invoked 113 cases, while Airbnb violations came up 28 percent more often in eviction notices.

This isn't, however, Airbnb's fault — one guy quoted in the article marched down to Airbnb's headquarters after he was served an eviction notice, claiming the site doesn't do a good enough job warning hosts of potential risks. But we're all adults here, right? Can you read a lease? Good.
