According to WMAR, after a procedural final vote the Baltimore City Council has passed a bill regulating short-term rentals such as Airbnb.

The Baltimore Sun reported on the details of the bill:

The legislation would require hosts using the rental platforms to register with city authorities and impose a 9.5 percent hotel tax on Airbnb-style stays. It would also ban people from renting properties other than their primary homes.

…

It does include a grandfather clause that would allow existing hosts to rent their home plus one other property.

The WMAR article notes that the bill is effective at the end of this year with the tax portions having an effective date of the end of 2019.
