As required under the City of Chicago Department of Buildings municipal code, owners of occupied buildings and vacant buildings alike are required to file a Critical Façade Evaluation at mandated intervals ranging from two to four years depending on the type and category of building in which the examination is to be performed. The ordinance allows for owners of occupied spaces/buildings to file an Ongoing Critical Façade Inspection and Repair Report provided that the property/building has filed and met all regulatory requirements.
The professional shall prepare a report in writing on the critical examination, describing the condition of the exterior walls and enclosures on the building and including a record of the components and cladding including, without limitation, any broken glass and loose or missing glazing components; loose masonry, concrete, EIFS, metal, stone or terra cotta; and all significant deterioration and displacement observed. Additionally, the report shall indicate any imminently dangerous conditions. If any remedial work is recommended, the report shall indicate the nature and urgency of such work.
