I'm on the board of the Norwegian equivalent of a condo association, and I wish we could fine an owner every time we got complaints from other residents! Unfortunately the laws still have loopholes that make it very hard for us to hold him accountable as long as he claims to actually be living there. --In Norway you have to have a primary residence registered, and you're allowed to rent out spare rooms in your primary residence, even on short-term sites. We'd basically have to spend a lot of money to have a 3rd party come knocking on the door every night for several months to prove whether or not he's really living there so that we can take proper action.
