You would need to be away for at least 30 days and your prospective tenant would need to sign a lease for at least 30 days. Then, under this legislation, it's kosher, and would be governed by your own tenancy agreement/coop board/whatever.
Yeah, I'm not asking for an explanation of the law. I understand how it works, and that's the problem. It bans the usecase of allowing people to rent out while they travel, which wasn't the stated intention of the law.
The last Airbnb I stayed in was obviously lived in, but the fellow was temporarily out - probably with his GF. The one before that was a really nice spare cottage in the backyard of a couple grandparents. Both experiences were far better than any hotel, even fancy ones. I'm really bummed at this response to airbnb.
So if the sharing economy is REALLY about sharing, there's no problem!
