A tenant can sublet without the landlord's permission, even if the lease says its forbidden. If your landlord decides to deny your sublet request, the denial must be reasonable.Your landlord cannot unreasonably withhold consent to sublease. No. Unless your lease already grants consent, you will need the written consent of the landlord for a sublease. A tenant cannot sublease someone else's property without permission in writing. If the tenant named in the lease moves out, the remaining occupant has no right to continue in occupancy without the landlord's express consent. The Guide explains what you should know when applying to rent, living in a rented property, and dealing with the end of a lease. If you have a lease for a set term, like one year, you can sublet with or without your landlord's permission, unless they prohibit this in the written lease. The Lease and this Agreement constitute the entire agreement of the parties with respect to Landlord's consent to the Sublease. If you have an oral lease and your landlord wants you to sign a written agreement – you still don't have to sign anything that contains new terms.
