Can a tenant be evicted for subletting the property without permission?

Unauthorised subletting — renting out the premises (or part of it) to someone else without the landlord's knowledge or consent — is a commonly recognised ground for eviction under most rent laws and standard tenancy agreements, since it fundamentally breaches the trust and terms of the original tenancy.

To pursue eviction on this basis, you would generally need to follow the proper legal process — typically starting with a notice to your tenant citing the unauthorised subletting, and if they don't rectify it or vacate, proceeding with formal eviction proceedings before the relevant forum.

It helps to gather clear evidence of the subletting — such as the sub-tenant's presence, any payments being made to your tenant by them, or their own admission — since this will need to be established as part of your eviction case. Consulting a property lawyer about the specific eviction process applicable in your state would be the sensible next step.
