Single lodger in a private residence
A lodger is 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. Most lodgers have the same rights as tenants.
However, in the case of a single lodger in a house where there are no other lodgers, the owner can evict the lodger without using formal eviction proceedings. The owner can give the lodger written notice that the lodger cannot continue to use the room. The amount of notice must be the same as the number of days between rent payments (for example, 30 days). (See "Tenant's notice to end a periodic tenancy".) When the owner has given the lodger proper notice and the time has expired, the lodger has no further right to remain in the owner's house and may be removed as a trespasser.
