Gross floor area of work
The gross floor area of work entered on the permit application must be determined for each floor level by drawing a single boundary around all work on that level to be performed under the permit. In a residential occupancy, where work will occur on multiple floor levels, the area of work on each floor level must be added together. In a non-residential occupancy, work is limited to a single floor level. Incidental work that must be performed in an electrical, mechanical, or utility room/space that is not immediately adjacent to the remainder of the work may be excluded from this measurement.
Existing occupancy and use
This permit type cannot be used for work involving the following occupancies: educational (Group E), factory/industrial (Group F), high hazard (Group H), institutional (Group I), or storage (Group S). Existing occupancies must be classified in accordance with Chapter 3 of the Chicago Building Code.
Electrical work
Electrical work must comply with the Terms and Conditions for Electrical Work.
Mechanical (HVAC) work
Mechanical work must comply with the Terms and Conditions for Mechanical (HVAC) Work.
Plumbing work
Plumbing work must comply with the Terms and Conditions for Plumbing Work.
Existing openings and penetrations in walls and floors
Where work under this permit will either abandon or reuse an existing opening in or penetration of a floor or wall that separates a residential unit or non-residential unit from another unit, a shared corridor, or a stairway, the opening or penetration must be firestopped or otherwise protected as required by the Chicago Building Code.
Nonstructural interior alteration
No initial buildout
This permit cannot be used for the initial buildout of a space that has never been legally occupied, such as a tenant space originally permitted as an unfinished “shell.”
No change of occupancy
This permit cannot be used for work that will result in a change of occupancy, as that term is defined in the Chicago Building Rehabilitation Code.
No new food establishment
This permit cannot be used for work that will create a new food establishment or commercial kitchen site that is subject to inspection by the Chicago Department of Public Health (CDPH). This permit can be used for alterations to an existing food service establishment or commercial kitchen site.
No conversion of unconditioned space
This permit cannot be used to convert unconditioned space, such as an unheated basement, attic, or garage, into conditioned living space.
Adequate means of egress
This permit does not authorize work in a space that does not have means of egress (exiting) in compliance with the Chicago Minimum Requirements for Existing Buildings before work begins. It is the responsibility of the permit applicant to determine if existing means of egress are adequate before submitting a permit application through the Express Permit Program.
Electrical service
This permit cannot be used to install a new electrical service exceeding 200 amps.
Water demand
This permit cannot be used for plumbing work that will increase the existing water demand by more than 5 water supply fixture units, as determined in accordance with Appendix A to the Chicago Plumbing Code.
New openings and penetrations in walls and floors
This permit does not authorize any new opening or penetration exceeding 1 inch in diameter in a floor or wall that separates a residential unit or non-residential unit from another unit or from a shared corridor. This permit does not authorize any openings or penetrations in any wall enclosing an exit stairway or other type of exit. Any new opening or penetration must be firestopped or otherwise protected as required by the Chicago Building Code.
Work in residential units—hardwired smoke alarms and carbon monoxide detectors
Where this permit authorizes work in a residential unit, this permit requires the installation of smoke alarms and carbon monoxide detectors throughout the unit in accordance with the Chicago Minimum Requirements for Existing Buildings. In most cases, hardwired alarms must be installed, and battery-powered alarms are not acceptable.
Work in residential units—natural light and ventilation
Where this permit authorizes work in a residential unit, all spaces that are reconfigured under the permit must be provided with natural light and natural ventilation as required by the Chicago Building Rehabilitation Code. Existing spaces must have access to natural light and natural ventilation as required by the Chicago Minimum Requirements for Existing Buildings.
Nonstructural preparatory demolition
Associated building permit application
This type of permit will only be issued when there is a plan-based building permit application under review for the same building or building area and the construction documents submitted to the Department of Buildings as part of the plan-based permit application are sealed by an Illinois-licensed architect or structural engineer and show both the scope of demolition and scope of proposed work.
Conditional approval
This permit is conditional upon issuance of the associated plan-based permit. This permit allows nonstructural preparatory demolition work to begin, but if the associated permit is not issued within 1 year, the recipient of this permit is responsible for restoring the space to a safe condition.
Means of egress
This type of permit does not authorize interior demolition work that will affect a corridor or similar egress component that serves an occupied portion of the building. This type of permit does not authorize preparatory demolition of any stairway, whether the building is occupied or not.
Fire protection systems
This permit does not authorize disabling or removing any active fire protection system (fire alarm system, sprinkler system, standpipe system, etc.) without separate written approval or a separate permit from the Chicago Fire Department.
Removal of unpermitted residential unit features
No removal of a legally established residential unit
This permit cannot be used to eliminate a legally established residential unit (dwelling unit or sleeping unit). This permit is only for removing features of a residential unit that were originally built without required permits.
Unsafe conditions
The person performing work under this permit is responsible for fully abating conditions that are unsafe to building occupants. This includes deenergizing and removing unsafe wiring, removing plumbing (water supply and drain piping) that does not comply with the Chicago Plumbing Code, and sealing off sources of sewer gas.

Removal of interior doors
Where the use after removal that is identified in the permit application is either storage or utility/laundry, this permit requires removal of all doors that create spaces resembling bedrooms and closets.
