The Massachusetts Land Court has ruled that a town may amend its zoning ordinance to prohibit Airbnb use and that retroactive application of the new law to those who established Airbnb use before it was passed is lawful. The owner had no right to have the prior Airbnb use "grandfathered in" as a prior nonconforming use under state statutes. Styller v. Aylward, 2018 Mass. LCR LEXIS 194 (Mass. Land Ct. 2018).
