Sublets
What happens if I sublet without telling my landlord?

Short answer
If your lease requires consent, an unapproved sublet is usually a lease violation. The landlord may be able to charge fees, refuse to renew, or start an eviction that affects both you and your subtenant. You also lose leverage if something goes wrong, because the arrangement was not allowed to begin with.
People often assume the landlord will not notice. Neighbors, building staff, key fob logs, doormen and new names on packages make it more visible than you expect, and a noise complaint or repair visit can reveal it at the worst moment.
The risks land on both sides:
- For you: a lease violation notice, possible eviction, a harder time renting next time, and you are still responsible for any damage or unpaid rent.
- For the subtenant: they can be told to leave with little warning, have no relationship with the landlord, and may lose money they prepaid.
- For both: an unapproved subtenant may not be covered by the building's rules or your renters insurance.
If you have already sublet without permission, the safest step is usually to ask for approval now and present the subtenant as an applicant. Many landlords prefer a reasonable, paying occupant to an empty unit.
If you are looking for a sublet, ask whether the landlord has approved it. Someone who says "don't mention this to the building" is telling you the arrangement could end suddenly.
