More than 130 people have RSVP'd for a protest targeting "Airbnb's impact on our affordable rental housing. It begins tonight at 5:30pm, at 1937 Mason St.

The protesters plan to tour some of the area's short-term rentals (STRs) under the title "Today! Stop Airbnb Evictions. #RightToARoof Regional Day of Action." So if you see a crowd dressed in all black moving through the streets, that's why.

"As part of a regional day of action, tenants from six counties across the Bay Area are demanding the 'Right to a Roof,' says the Facebook event page. "In SF, we're protesting Airbnb's impact on our affordable rental housing." An image shows a Grim Reaper standing over the iconic row of "Painted Ladies" near Alamo Square.

Short-term rentals have been a hot-button issue this election season. Many are opposed to allowing entire buildings to become de facto unregulated hotels, while others say STRs actually help some tenants afford the city's outrageous rents. Proposition F, if passed in November, would add more regulations to the practice, including making Airbnb hosts register as a business. 

The city issued a press release on Tuesday, saying that its Office of Short Term Rental Administration & Enforcement (OSTR) was enforcing current short-term rental legislation. "The office moved forward with three more cases, issuing final decisions by a hearing officer that resulted in nearly $100,000 in fines against multiple properties," it read in part. "The registration of properties, as well as investigations and enforcement actions, will continue as the core objective of the Office of Short-Term Rentals."

“I want to express my appreciation to the coordinated effort between many city agencies, especially the Planning Department Enforcement Team," Kevin Guy, Director of the Office of Short Term Rental Administration & Enforcement, said in the release. "If you are eligible to share your home, we will help you register; however, if you break the law and contribute to our city’s housing crisis, we will continue to be vigilant with our enforcement and, if appropriate, issue fines and penalties.”
