Boston, MA

Boston passed STR regulations in 2019, allowing them under certain conditions. It recognizes three classes: limited share rentals (where a spare bedroom in the operator’s home is the STR), home share rentals (where the home the operator occupies is sometimes a STR), or owner-adjacent rentals (where another unit in a duplex or triplex the operator owns and lives in is an STR). All STRs must be in owner-occupied buildings and cannot exist in buildings with more than three units. STRs must register with the city and pay a fee. The estimated number of STRs in Boston decreased from roughly 6,000 before the regulations to 841 in 2021.
