What is a subletting clause in a lease?
A subletting clause controls whether you can let someone else live in your rental and take over some or all of the rent. Leases often require the landlord's written consent. Some states say that consent can't be unreasonably withheld, which protects tenants who need flexibility.
Is it normal?
Standard. An outright ban on subletting is common but limits your flexibility; a 'consent not unreasonably withheld' version is more tenant-friendly.
What to watch for
- A total ban with no exceptions, even for short absences.
- Consent left entirely to the landlord's discretion.
- Fees just to request permission to sublet.
How to negotiate it
- Ask for 'consent shall not be unreasonably withheld.'
- Request the right to sublet for a defined period (e.g., a semester abroad).
- Clarify whether roommates count as subletting.
Example
"Tenant shall not sublet the premises without Landlord's prior written consent, which shall not be unreasonably withheld."

Can my landlord refuse to let me sublet?
Often yes, unless your state or lease says consent can't be unreasonably withheld. Always get permission in writing before subletting.
