TL;DR: Subletting without your landlord's written consent is one of the most common causes of lease termination — yet the rules vary significantly across jurisdictions. Know what you can and cannot do before you hand over keys to anyone.
Whether you need to travel for work, share costs with a flatmate, or temporarily vacate while keeping your home, subletting sounds like an attractive solution. But subletting creates legal complexity: you become a "head tenant" with obligations to both your landlord and your subtenant. Getting it wrong can cost you your tenancy.
This guide covers subletting rules in the UK, France, Sweden, Australia, New Zealand, Canada, and the USA.

Subletting (also called subleasing) occurs when a tenant rents out all or part of their rented accommodation to another person — the subtenant — while the original lease with the landlord remains in force.
Key distinctions:
All three carry legal implications and typically require landlord consent.
Most residential leases contain a clause prohibiting subletting without the landlord's prior written consent. Subletting in breach of this clause can:
Even where consent is not legally required, it is best practice to notify your landlord in writing.

Locate the subletting or assignment clause in your tenancy agreement. Note:
Write to your landlord requesting permission to sublet. Include:
Keep a copy of this request. Track your landlord's response deadline using the MmowW Scrib🐮 Filing Deadlines tool.
Do not hand over keys until you have written consent. Verbal permission is unreliable and difficult to prove.
If your landlord refuses:
Once consent is obtained, create a written sublease that covers:
As head tenant, you remain fully liable to the landlord. Your subtenant's failure to pay rent or cause damage does not reduce your obligations under the head lease.
Contact your contents insurance provider. Having a subtenant may affect your policy. You may need to upgrade to a landlord policy or ensure the subtenant has their own contents insurance.
Short-term rental platforms have created a new category of subletting risk. Across all seven jurisdictions, listing your rental property on Airbnb without landlord consent is almost certainly a breach of your lease. Additional risks include:
If you simply want to rent a room in your home while you continue to live there, this may be treated as "taking in a lodger" rather than subletting. In the UK, for example, the Rent a Room scheme allows you to earn up to £7,500 per year tax-free by renting a furnished room in your primary residence. The landlord's consent is still typically required, but some leases are more permissive about lodgers than full subletting.

Q: Can my landlord refuse to let me take in a lodger?
A: In most jurisdictions, yes — unless your lease specifically permits it or the landlord's refusal is unreasonable under local law. In Sweden, an unreasonable refusal can be overridden by Hyresnämnden. In New Zealand and some Canadian provinces, landlords cannot unreasonably withhold consent to subletting.
Q: What happens if I sublet without permission and my landlord finds out?
A: Your landlord may have grounds to issue a notice to quit or begin eviction proceedings for breach of the tenancy agreement. In social housing in the UK, unlawful subletting is a criminal offence with potential fines and loss of tenancy.
Q: Am I responsible if my subtenant damages the property?
A: Yes. As head tenant, you remain the landlord's tenant and bear full responsibility under the head lease. You can seek to recover damages from your subtenant, but you cannot use their actions as a defence against the landlord's claims.
