a person who lives with you, is provided with meals and services (such as cleaning, provision of linen etc), and who does not have her/his own separate accommodation
Lodgers don't have "exclusive possession" of their room(s). Basically, if your landlord provides your with linen and cleans the place for you then you are probably a "lodger". Give the Illawarra Legal Centre's Tenancy Service if you want to find out. (02) 42743475.
someone who rents a room but does not have exclusive possession of the room. If you rent a room in a hotel-style house, where you share a laundry, kitchen and other areas, and/or where the landlord provides you with sheets, cleaning or other services, then you may legally be a lodger. Some people in share houses may also be classified as lodgers, for example, if you are renting a room in an owner-occupied house or the place is run by a head tenant and you are not seen to have an equal say in the running of the house. Lodgers are not covered by the Residential Tenancies Act which means they have virtually no protection in relation to their housing. Rent increases, evictions, repairs and privacy are the greatest problems. Boarders are lodgers whose meals are provided by the landlord or head tenant.
a person who lives in a room in a house where the owner lives. The owner can enter all areas occupied by the lodger, and has overall control of the house.
