Chicago Demolition Permit Requirements, Explained

Chicago's demolition permit is a checklist of approvals from different City agencies, and the permit does not issue until the checklist is complete. Owners who treat it as a single form and a fee usually lose weeks finding out which pieces were missing. Here is what the City's own pages say, so you can plan the order of work and ask your contractor the right questions.

All of this changes often. Use it to understand the process, then confirm current steps with the Department of Buildings before you file.

When does Chicago require a demolition permit?

The Department of Buildings says a demolition (wrecking) permit is required to demolish an entire building or structure, to demolish substantially all of the above-grade portion of one, or to alter a building in a way that permanently reduces its area (City of Chicago).

The listed exceptions are narrow:

• Wood-frame private garages that are replaced through the Express Permit Program.
• Small structures that do not need a permit to build.
• Emergency work authorized by the Commissioner.

Everything else, from a brick two-flat to a commercial building, falls under the wrecking permit. If you are only taking down part of a building, ask the Department of Buildings which permit fits. Demolition that permanently reduces the area still counts.

What changed in 2026

As of August 10, 2026, demolition applications go through the City's Inspection, Permitting and Licensing Portal. Applications started under the old process before August 6, 2026 may continue until December 30, 2026 (City of Chicago).

That matters because older contractor websites and blog posts still describe the former email and Form 480 process. If a source tells you to email a form to DOB, it is out of date. Ask your contractor which process your application is under.

What approvals come before the permit issues?

The City lists these approvals as required before issuance (City of Chicago):

1. Chicago Department of Public Health (CDPH) Demolition Notice of Intent. This covers dust and hazardous material measures, including asbestos.
2. Rodent control. A licensed pest company baits the site, files an affidavit, and the site passes a Streets and Sanitation inspection. If rodents are found, they must be abated within 14 days before filing.
3. Public way permit. Either a CDOT right-of-way permit or a written no-permit determination.
4. Sewer disconnection. A Water Management cut-and-seal permit, or a written determination.
5. Water disconnection. A cut-and-seal permit pulled by a licensed plumbing contractor, plus a hydrant use permit or an alternative water source.
6. Housing approval. Department of Housing approval if the building has dwelling units.
7. Historic review. Department of Planning and Development Historic Preservation review if the building is orange or red in the Chicago Historic Resources Survey, or is a landmark.
8. Pre-permit inspection for complex demolition, and flammable tank permits where they apply.

The City also expects photographs taken within 60 days, a signed contract, an excavation certification, and a structural condition report and site safety plan where required (City of Chicago).

Who applies, and who is allowed to do the work

Two rules decide who can be on the paperwork.

The applicant must be a property owner. Demolition permit applicants have to be owners (City of Chicago). A contractor can run the process for you, but the owner is the applicant.

A City-licensed general contractor must do the work. Demolition must be performed by one (City of Chicago). The City's general contractor license is required for most construction, alteration, repair and demolition work (City of Chicago). License classes matter here: Class A and B licenses cover ordinary or complex demolition, Classes C and D cover ordinary demolition only, and Class E does not cover demolition (City of Chicago).

An owner can't act as their own general contractor for demolition. An individual without a general contractor license cannot perform or oversee work that needs a demolition permit or an excavation notice (City of Chicago). More on choosing a demolition contractor in our contractor guide.

The wrecking contractor also has to carry the City's required bond and liability insurance, naming the City as additional insured (2019 code text).

What changes if the building touches a neighbor

If your building shares a wall with another, the application needs one of two things: a survey by an Illinois-licensed land surveyor showing everything to be demolished is on your property, or a letter signed by the adjoining owner authorizing the demolition. The code also requires a design professional to certify that the adjoining structure needs no bracing, or drawings and the neighbor's written consent. The contractor must indemnify adjacent owners (City of Chicago).

The DOB page does not list a general "notify your neighbors" mailing requirement. That is still no reason to skip the conversation, because your neighbor's signature may be what gets the permit moving. See demolishing an attached building for what shared-wall jobs involve.

Utilities: what the City says and what it doesn't

The City requires water and sewer cut-and-seal permits and inspection as part of demolition (City of Chicago). On gas and electric, the DOB demolition page, as we read it, does not list gas or electric disconnection among the approvals. We won't state a gas or electric step as a City checklist item. Ask your contractor and the utilities how those disconnections are handled for your building, and read who shuts off utilities before a demolition.

Asbestos and the health department notice

CDPH requires a Demolition Notice of Intent, submitted through the City permit portal at least 10 working days before any non-emergency demolition starts. A separate Notice of Asbestos Abatement is due at least 10 working days before work that disturbs any amount of asbestos in any building except single-family homes (CDPH).

At the federal level, the asbestos NESHAP rule covers demolition and renovation of all facilities except residential buildings with four or fewer dwelling units (US EPA). So a small residential building may be outside the federal rule while the City's demolition notice still applies. Do not read the federal exemption as "no asbestos issue." Details are in what must happen first with asbestos.

Special cases: delay, surcharge and implosion

• The 90-day delay. If a building is color-coded orange or red in the 1996 Chicago Historic Resources Survey, a permit may not issue for up to 90 days so the Department of Planning and Development can look at preservation options. The clock starts when a complete application and photographs go to Historic Preservation (City of Chicago). It is not a rule for every building. See does your building trigger the delay.
• The surcharge. Residential demolition in the Pilsen and 606 pilot areas carries a surcharge, and dwelling-unit demolitions need Department of Housing sign-off through its e-form. This is not a citywide surcharge (City of Chicago). Our fees explainer covers it.
• Implosion. Explosives need a separate Business Affairs and Consumer Protection permit for demolition by implosion, and demolition in the Loop freight tunnel area needs CDOT review (City of Chicago).

What the permit clock looks like after you have it

Once the permit is paid, work must begin within 6 months and cannot stop for more than 12 months. A demolition application expires after 120 days of inactivity, with one 90-day extension. Inspections are requested online at completion and after grading, and debris recycling paperwork goes to CDPH at the end, where 50 percent of recyclable debris must be recycled (City of Chicago). We don't promise how long review takes. What slows a file is covered in what slows a demolition permit down.

What do owners get wrong?

Use our permit checklist to track each piece, and the demolition guide for the whole job from permit to final grading.

If you own a building you plan to take down, Akats runs the demolition permit process and the work itself, and can tell you which of these pieces apply to your property before you file.
