An Illinois Vacancy Affidavit-10 or More Stories, also known as a Vacancy Affidavit or Statement of Vacancy, is a legal document used to certify that a dwelling unit in Illinois is vacant. It is typically required to be completed by the owner or landlord of the property when a tenant moves out or when a unit becomes vacant. It must be notarized and filed with the local government. The affidavit is intended to provide assurance that the unit is vacant and ready for a new tenant. For buildings with ten or more stories, the affidavit must also include the following information: the address of the building, the total number of stories, the number of vacant units, the total number of units in the building, the name, address, and telephone number of the managing agent, the name, address, and telephone number of the owner, and the date the unit became vacant.
