There can be multiple areas containing a primary function in a single building. Primary function areas are not limited to public use areas. Mixed-use facilities may include numerous primary function areas for each use. Primary function areas include, but are not limited to, the customer services lobby of a bank, the dining area of a cafeteria, the meeting rooms in a conference center, as well as offices and other employee areas in which the activities of the public accommodation or other private entity using the facility are carried out. Primary function areas do not include: mechanical rooms, boiler rooms, storage supply rooms, employee lounges or locker rooms, janitorial closets, entrances or corridors. Restrooms are not primary function areas unless the provision of restrooms is a primary purpose of the facility, such as in highway rest stops.
REGISTERED DESIGN PROFESSIONAL. As defined in Chapter 2 of the Chicago Construction Codes Administrative Provisions.
REHABILITATION. Any work type described in this code undertaken in an existing building or existing structure, including addition, alteration, change of occupancy, relocation and repair.
REPAIR. The reconstruction, replacement or renewal of any part of an existing building for the purpose of its maintenance or to correct damage.
REROOFING. The process of recovering or replacing an existing roof covering. See "Roof recover" and "Roof replacement."
ROOF RECOVER. The process of installing an additional roof covering over a prepared existing roof covering without removing the existing roof covering.
ROOF REPAIR. Reconstruction or renewal of any part of an existing roof for the purpose of correcting damage or restoring the predamage condition.

SEISMIC FORCES. The loads, forces and requirements prescribed herein, related to the response of the building to earthquake motions, to be used in the analysis and design of the structure and its components. Seismic forces are considered either full or reduced, as provided in Chapter 3.
STRUCTURAL CHANGE (for Section 305). Changes to or rearrangement of the structural elements, plumbing fixture changes or changes to or rearrangement of the plan configuration of walls and full height partitions.
STRUCTURAL ELEMENTS (for Section 305). A loadcarrying component of a structural system of a building, structure or facility, such as a foundation wall, column, strut, slab, beam, girder, truss or arch; or components of the primary structural frame.
SUBSTANTIAL DAMAGE. For the purpose of determining compliance with the flood provisions of this code, damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred.
SUBSTANTIAL IMPROVEMENT. For the purpose of determining compliance with the flood provisions of this code, any repair, alteration, addition, or improvement of a building or structure, the cost of which equals or exceeds 50 percent of the market value of the structure, before the improvement or repair is started. If the structure has sustained substantial damage, any repairs are considered substantial improvement regardless of the actual repair work performed. The term does not, however, include either of the following:
- Any project for improvement of a building required to correct existing health, sanitary, or safety code violations identified by the building official and that is the minimum necessary to ensure safe living conditions.
- Any alteration of a historic structure, provided that the alteration will not preclude the structure's continued designation as a historic structure.
SUBSTANTIAL STRUCTURAL ALTERATION.

The areas to be counted toward the 30 percent shall include mezzanines, penthouses, and in-filled courts and shafts tributary to the altered structural elements.
SUBSTANTIAL STRUCTURAL DAMAGE. A condition where any of the following apply:
- The vertical elements of the lateral force-resisting system have suffered damage such that the lateral loadcarrying capacity of any story in any horizontal direction has been reduced by more than 33 percent from its predamage condition.
- The capacity of any vertical component carrying gravity load, or any group of such components, that has a tributary area more than 30 percent of the total area of the structure's floor(s) and roof(s) has been reduced more than 20 percent from its predamage condition, and the remaining capacity of such affected elements, with respect to all dead and live loads, is less than 75 percent of that required by the Chicago Building Code for new buildings of similar structure, purpose and location.
- The capacity of any structural component carrying snow load, or any group of such components, that supports more than 30 percent of the roof area of similar construction has been reduced more than 20 percent from its predamage condition, and the remaining capacity with respect to dead, live and snow loads is less than 75 percent of that required by the Chicago Building Code for new buildings of similar structure, purpose and location.
TECHNICALLY INFEASIBLE. An alteration of a facility that has little likelihood of being accomplished because the existing structural conditions require the removal or alteration of a load-bearing member that is an essential part of the primary structural frame, or because other existing physical or site constraints prohibit modification or addition of elements, spaces or features which are in full and strict compliance with the minimum requirements for new construction and which are necessary to provide accessibility.
UNSAFE. Buildings, structures or equipment that are unsanitary, or that are deficient due to inadequate means of egress facilities, inadequate light and ventilation, or that constitute a fire hazard, or in which the structure or individual structural members meet the definition of "Dangerous," or that are otherwise dangerous to human life or the public welfare, or that involve illegal or improper occupancy or inadequate maintenance shall be deemed unsafe. A vacant structure that is not secured against entry shall be deemed unsafe.
WORK AREA. The portion or portions of a building consisting of all reconfigured spaces as indicated on the construction documents. Work area excludes other portions of the building where incidental work entailed by the intended work must be performed and portions of the building where work not initially intended by the owner is specifically required by the Chicago Construction Codes.
