This Guardian article linked below is a good summary of Airbnb regulation around the world.
It's an omission that Maui, Oahu, and Kauai were not mentioned. Then again, regulation of vacation rentals is old news in the state of Hawaii.

The cities cracking down on Airbnb
The idea of Airbnb and other short-term lets as an alternative to over-priced hotels may soon be over, writes Patrick Collinson. Many cities have begun to introduce new rules, after residents complained about being overwhelmed by weekend visitors banging wheelie bags up stairs, breaching building security rules, and loud parties. Pressure has also come from hotel groups and local politicians who have lost revenue from hotel taxes.
In June, a court upheld Berlin’s de facto ban on short-term rentals. People who let more than 50% of their apartment on a short-term basis without a permit risk a fine of €100,000 (£85,000). City authorities were concerned that the availability of affordable housing was being severely threatened by the rise of short-term letting. Munich and Hamburg have also taken steps to curb
The city that is home to Airbnb’s HQ is also one of its fiercest opponents. Hosts have to register with the authorities; if Airbnb advertises an unregistered property it can be fined $1,000 (£755) a day for each listing. An action group in the city has posted “wanted” flyers. The crime? “Airbnb’ing our community” and “destroying affordable housing for immigrant, minority, and low income families”.
The city’s rental laws ban apartments in buildings with three or more units from being rented out for less than 30 days. Landlords who flout the ban can be fined as much as $7,500. But home sharing – where the host is present – is legal. Critics say that short-term rental companies like Airbnb are flooding the city’s housing market, reducing available housing stock citywide by 10%, according to a study released in June.
The Catalan city has been among the most aggressive in fighting Airbnb, slapping a €30,000 fine on the site for hosting illegal tourist lets in 2014. Flat owners have to list their apartments with the city’s tourism register, obtain a licence and be responsible for collecting the daily €0.65 tourist tax.
The Spanish capital set a minimum stay of five nights in private homes and apartments which, given the typical three-night stay on Airbnb, ruled out most rentals. But the directive was later overturned in court.
The 1,600 short-term lets in Iceland’s capital have to operate under strict rules introduced in June. The legislation limits the number of days residents can offer rentals in their properties to 90 days a year before they must pay business tax.
