Yes. Before a Chicago demolition permit issues, the City's checklist requires rodent control through Streets and Sanitation: a licensed pest company baits the site, files an affidavit, and the site passes inspection. The code section behind it is MCC 14A-4-407.3. If rodents are found, the checklist points to abatement within 14 days before filing, so confirm timing with the Department of Buildings and book the pest company early.
The rodent control requirement for a Chicago demolition is the item owners do not see coming. It is not a form you fill in at the end. It is an approval that has to be in hand before the permit issues, and a missing one is a quiet reason an application stalls.
What does the City require for rodent control?
The City's demolition approval checklist lists rodent control through Streets and Sanitation as one of the approvals needed before issuance. The steps are specific: a licensed pest company baits the building, an affidavit is filed, and the site has to pass inspection (City of Chicago). The checklist also cites Municipal Code section 14A-4-407.3 for it.
It sits next to the other required approvals, not above them: the health department's Demolition Notice of Intent, the right-of-way determination from CDOT, and the sewer and water cut-and-seal steps. You can see the whole list in our demolition permit requirements article, or print the demolition permit checklist.
What if rodents are found?
The same checklist notes that if rodents are found, abatement is expected within 14 days before filing (City of Chicago). Treat that as a planning signal, not a promise about how long anything takes. Exact timing can change, so confirm it with the Department of Buildings (DOB) before you schedule.
The City does not spell out its reasoning on the checklist we read. The logic is familiar to anyone who has torn down an old building: when a structure comes down, whatever lives in it and under it gets pushed out into the neighbors' yards and alleys. Baiting first deals with that before the machine arrives.
How to keep it from stalling your permit
Rodent control is on the owner's critical path whether or not the contractor mentions it. A few habits help:
- Ask for it by name. When you review a demolition estimate, look for the rodent baiting and the affidavit. If neither is mentioned, ask who handles it.
- Book the pest company early. The licensed pest company is a separate trade from the demolition crew, so it has its own schedule.
- Match it to the process you are in. As of August 10, 2026, demolition applications go through the City's Inspection, Permitting and Licensing Portal, and older contractor sites may describe a previous process (City of Chicago).
- Watch the clock. A demolition application expires after 120 days of inactivity, with one 90-day extension (City of Chicago). A rodent step that sits undone is the kind of thing that eats those days. For how the rest of the sequence affects timing, see what slows a Chicago demolition permit down.
On older two-flats and frame houses that have sat empty, rodents are often the first thing owners find once someone opens the building up. A typical pattern is an owner who budgets for the crew and the dumpster and never plans for the pest company or its paperwork. It shows up as a late surprise on the checklist.

Common questions
Yes. The City's demolition checklist requires rodent control through Streets and Sanitation: a licensed pest company baits the site, files an affidavit, and the site passes inspection before the permit issues.
A licensed pest company, according to the City's checklist, not the demolition crew itself. Ask your contractor who is handling it and when the affidavit will be filed.
It can. The rodent approval is on the list of items needed before issuance, so an application missing it waits. Check current requirements with the Department of Buildings.
