According to section 4 of the Residential Tenancy Act (RTA), the following type of accommodation is not covered by the RTA:
living accommodation in which the tenant shares bathroom or kitchen facilities with the owner of that accommodation
Occupants / Roommates: There is another living situation that may not be covered by the RTA, but is also not mentioned in section 4. If you rent from a tenant with whom you live, you may not be protected. This type of setup is common in shared houses where a “head-tenant” rents out a room to a roommate. Unless the landlord agrees to add the new roommate as a “tenant”, that person will most likely be considered an “occupant/roommate” and not be covered under the RTA. See RTB Policy Guideline 19 for more information.
If the Residential Tenancy Act does not cover your living situation, you will not be able to apply for dispute resolution through the RTB. Instead, you may need to use Small Claims Court, the Civil Resolution Tribunal, or BC Supreme Court.
