How Long Does a Chicago Demolition Permit Take? What Slows It Down

How long does it take to get a demolition permit in Chicago? Nobody can honestly tell you before looking at your building, and anyone who quotes a number is guessing. The permit is not one review. It is a stack of approvals from different City offices, some with fixed notice periods, and the slowest piece sets your pace.

This article lays out what the pieces are, which ones have a published clock, and where owners lose time without realizing it. For the full list of what the permit requires, see Chicago demolition permit requirements.

What does Chicago actually need before a demolition permit issues?

The City's pre-permit checklist is the reason timing varies. Approvals include a CDPH Demolition Notice of Intent, Streets and Sanitation rodent control, a public right-of-way permit or written no-permit determination, sewer and water cut-and-seal permits, hydrant use or an alternative water source, Department of Housing approval if the building has dwelling units, and Historic Preservation review for orange or red buildings. It also calls for photographs taken within 60 days, a signed contract, an excavation certification, and a structural condition report and site safety plan where required.

Each office works on its own schedule. They do not all start when you file, because some items, like rodent control and cut-and-seal permits, have to be done by licensed companies and inspected first. A permit that is complete on paper but waiting on one inspection is still waiting.

Also note that applications now go through the City's Inspection, Permitting and Licensing Portal as of August 10, 2026. Applications started under the old process before August 6, 2026 may continue until December 30, 2026. Older contractor websites describe the old email and Form 480 process, so be careful whose instructions you are following.

Which parts have a published clock?

Some timing rules are written down. These are the ones we can cite.

These are rules, not predictions. They do not tell you how long the whole permit takes. They tell you what the clocks are inside it. Confirm current rules with the Department of Buildings, since they change.

What slows a demolition permit down most often?

These are the patterns, not a ranking.

1. Notices filed late. The CDPH notice has a 10 working day lead time. If it is filed the week you wanted to start, the start moves. See Chicago demolition and asbestos.

2. Rodent control not done first. The rodent step involves a licensed pest company baiting, an affidavit and an inspection. If the baiting has not happened, that approval does not exist yet. We explain it in why rodent baiting comes first.

3. An incomplete application. Missing photographs, a missing contract, or a missing certification sends the file back. Photographs are due within 60 days, so photos taken months ago may need to be retaken.

4. The building triggers a special review. An orange or red building in the 1996 Chicago Historic Resources Survey can face the up to 90 day delay. Only those buildings. Check yours using our demolition delay article. Landmarks are handled separately.

5. Dwelling units. If the building has dwelling units, Department of Housing approval is required. In the Pilsen and 606 pilot areas a residential demolition also carries a surcharge. It is not a citywide charge.

6. Utilities. The City's page requires water and sewer cut-and-seal permits and inspection. Do not assume these are quick. We have not confirmed any specific gas or electric disconnect requirement as a City permit step, so ask the Department of Buildings what applies to your building.

7. An attached building. If your building shares a wall, the City wants either a survey showing everything to be demolished is on your property or a letter from the adjoining owner authorizing the demolition, and a design professional's certification or drawings and the neighbor's consent. If the neighbor is slow, so are you. See demolishing an attached building.

8. Contractor licensing. The work must be done by a City-licensed general contractor. Hire one whose license class fits the building.

How long does the demolition itself take?

The permit and the teardown are separate questions, and we do not promise a duration for either. How long a demolition takes depends on the size and construction of the building, whether it is attached, hazardous materials, access, and debris handling. A detached garage and a three-story masonry building are not the same job.

After the work, there are close-out steps. Inspections are requested online at completion and after grading, and construction and demolition debris recycling paperwork goes to CDPH at the end. See where Chicago demolition debris goes.

How do you keep a demolition permit moving?

• Order long-lead items first: the CDPH notice, rodent control and the cut-and-seal permits.
• File complete. Gather photographs, contract, certifications and surveys before you submit.
• Find out early whether your building is orange or red in the Historic Resources Survey.
• Settle the neighbor question before you file if the building is attached.
• Hire a licensed contractor who knows the new portal process, not the old Form 480 process.
• Do not let the application sit. It expires after 120 days of inactivity.
• Start within the window. Work must begin within 6 months after the permit is paid.
