The new laws when they come in (soon) will specifically exclude genuine home sharing – i.e. letting a room or rooms when the resident is present. You committee mayhave to propose a new by-law (which has to be approved by 75 per cent of owners voting at a general meeting) which reflects this or their current by-law could be tossed out for being in conflict with strata law.
If you were looking for a business opportunity right now, you might consider low-cost CCTV cameras which are going to become very popular as strata committees try to prove that Airbnb hosts who say they are in residence, aren’t.
