No. That was easy. But, as is usually true in Chicago landlording, there’s much more to the story. What is a sublease anyway? A sublease is merely a further leasing (by the tenant) of already leased property. When a tenant, for whatever reason, is unable to meet lease obligations, that tenant might seek to lease the unit to a tenant of their own- a subtenant. By doing so, the original tenant finds a new party to assist in meeting the lease obligations.
