My Mother owns in lives in her own home on the Northern Beaches of Sydney in a single story 5 Bedroom house. We had a family friend move in for a number of years and live in a part of the house where we built a separate kitchen him. He is no longer there so I am trying to come up with a way so she can generate some passive income We are considering developing that section of the house so that it is sectioned off from the main part of the house and will include one large or two small bedrooms, upgrade to the kitchen, have it own bathroom (shower and toilet) with a small living/dining area. I have an option to have a washing machine in the kitchen, but would think it better to have two washing machines in the external laundry and having it shared. I am aware that there will need to be a separate entry, I have also read that you can get separate internal meters installed. But I'm not sure what else we should be considering? Will this affect her as she is on the Old Age Pension? What do I need to request from or advise the local council? Can we not share a Laundry? Any information or links to other threads that may have already covered this topic would be appreciated.
