I don't understand... according to AirBnB policy:
Devices like doorbell cameras and noise decibel monitors continue to be permitted on Airbnb and can be an effective, privacy-protective way for Hosts to monitor security for their home and get ahead of issues like unauthorized parties. However, Hosts will be required to disclose the presence and general location of any outdoor cameras before guests book. These cameras will also be prohibited from monitoring indoor spaces of a listing and are not allowed in certain outdoor areas where there’s a greater expectation of privacy, like an enclosed outdoor shower or sauna. Hosts are also required to disclose the presence of noise decibel monitors, which assess decibel level only and do not record or transmit sounds or conversations and are only allowed in common spaces of listings.
The garage is outside the living space and as long as you are disclosing it on the listing I don't see how it wouldn't be allowed. It's not a shower or sauna and is in most homes a primary entrance/exit to the home. Hotel's and apartments all have cameras at every entrance/exit including the garages.
Has anyone pressed this issue? This seems like a no-brainer.
