The city of San Francisco has voted against legislation that would have put the skids under the Airbnb model in its home city.
Initial results from the Proposition F (as the proposed piece of of regulation was known) vote showed 55% against the move, with 73,500 ballots cast by citizens.
Officials wanted to crack down on short-term home rentals in the city, effectively restricting home owners to 75 possible days a year (it currently stands at 90) when they could use home-sharing services such as Airbnb.
Airbnb and the likes of HomeAway and others would also have been forced to send detailed information to the authorities on the amount of revenue taken by owners.
Whilst the fiercely-fought campaign in the run up to the vote is probably not the biggest battle that Airbnb has or will wage, winning in its heartland of San Francisco will be seen as both a morale-boosting and legislative victory in its continued fight against authorities elsewhere around the world.
The company clearly knew what was at stake, having supposedly contributed close to $8 million to the "No To F" campaign war-chest which has been raging in the city in recent weeks.
Those arguing for Proposition F have included those pushing for more affordable housing in the city.
San Francisco has an average monthly rent in the region of $4,000 and the average home price is over $1 million.
Airbnb launched a somewhat ill-advised poster campaign ahead of the vote this week, poking the city authorities into spending the $12 million in hotel taxes that it has paid on specific services, such as keeping libraries open longer, placing escalators on hills or feeding expired parking meters.
The company quickly removed the ads after many citizens reacted angrily.
