Hello,I am looking at adding washing and dyer machines in a 4 plex unit.

But if they gov't changes to a 90 day minimum, you would have to operate as a 90 day rental or longer.And talking to local experts, if you want to own a STR on O'ahu, your safest bet is to buy a unit in a Condotel that is located in the "Resort" zone of Waikiki.
