What you are looking at
A permit with no final inspection is a permit the City issued, under which work demonstrably began, where the inspection record stops partway and never resumes. In the City's own audited sample it is the single most common pattern: of 42 fully constructed buildings examined, 25 had rough inspections but no final inspections at all.
Readers see this constantly and misread it in a specific way. They find a line reading rough electrical, passed, take the word passed as reassurance, and stop reading. The sequence ending at rough is not reassurance. It is the documented signature of a building that was completed and, on the City's own record, never finally inspected.
An open permit, in Chicago usage, means the case file was never closed out. That is a statement about paperwork. What matters underneath it is whether the inspections the permit required actually happened — and the permit record on its own does not distinguish passed from never asked for.
Why a permit stays open
The mechanism is simple and it is written into the code. Section 14A-5-502.3 of the Municipal Code of Chicago provides that the permit holder must notify the building official when work done pursuant to a permit is ready for inspection. The duty runs from the permit holder to the City, not the other way around.
The Office of Inspector General put it in plain terms in its 2022 audit: the Department of Buildings does not initiate an inspection unless it receives a request from a permit holder or a complaint, and its system does not flag general contractors who fail to ask for the inspections their permits require. When nobody asks, nothing happens, and the record simply ends.
The Department is responsive when it is asked. The audit found the Department handled 91.5% of the 155,756 construction inspection requests it received between 2017 and 2019. The failure is not in attendance. It is that the trigger sits entirely with the party least motivated to pull it once the building is finished.
The measured gap: 98.9% against 16.7%
The Inspector General measured what happens when something does force the inspection to occur, and the comparison is the most load-bearing figure on this subject.
For permits requiring a certificate of occupancy — the document the City issues when a building may lawfully be occupied — the Department completed 98.9% of required inspections across 1,236 unique permits, with 97.2% receiving passing marks. For new construction permits generally, the Department issued 5,351 between 2017 and 2019, and as of April 27, 2021 only 16.7% had all related inspections completed.
The reason for the divergence is structural rather than behavioral. Single-family homes and two- or three-flats do not require a certificate of occupancy. For those buildings nothing compels the final inspection, because the building can be lawfully occupied without one. Where the certificate is required, the inspection is a precondition of occupying, selling as occupiable or financing the building as such — so it gets done.
The Inspector General's own recommendation followed directly: consider requiring certificates of occupancy for a wider variety of buildings, as a way of forcing inspections to happen. That is the City's watchdog describing the gap between a permit record and proof of inspection, and proposing the only lever it could identify.
What the sample of 80 found
The audit examined 80 new construction permits in detail. The Inspector General states expressly that this was not a statistical sample and cannot be extrapolated, so the figures below describe those 80 permits and no wider population. They are nonetheless the most concrete published picture of the pattern.
Of the 80, construction status could not be assessed for 20, and 18 had no inspections because construction had not begun or the permit was voided. That left 42 fully constructed buildings — including 35 single-family homes, several of them already sold or listed for sale.
- 4 had no inspections at all.
- 25 had rough inspections but no final inspections.
- 10 had some rough inspections and no finals.
- 3 had some rough and some final inspections.
Across those 42 buildings, 398 inspections were required. The Department completed 198 of them. 11 of the 398 received passing marks. At least one inspection had been completed for 38 of the 42 buildings, which is precisely why a record showing some inspection activity proves so little on its own.
And it has not been corrected
The Department agreed with most of the audit's findings in 2022 and described a daily internal email listing permits over six months old with no inspection requests, which it intended to use to assign those locations to inspectors. It did not describe specific steps to improve data quality, and the report notes the Department had by then been working to replace its data system for over a decade.
In June 2024 the Inspector General published a follow-up and concluded that the Department had not implemented corrective actions for the audit's findings. That is the current published position: the gap was measured, acknowledged, and left in place.
What it establishes at a closing, and what it does not
What the record establishes is narrow and worth stating exactly. It establishes that the City authorized described work, that the inspection record for that work is incomplete, and that no City inspector has certified the finished result. For a building that required no certificate of occupancy, it establishes that the strongest record in the system was never going to exist and does not exist here.
What it does not establish is that anything is wrong with the building. An uninspected building is not a defective building. The absence is an absence of evidence, and treating it as evidence of a defect is the mirror-image error of treating a permit as evidence of quality. Both read the record as saying something it has no capacity to say.
Two further points of fact. The Municipal Code lists failure to obtain a required rough or final inspection, and failure to obtain a required certificate of occupancy, among the grounds on which a person's permit privileges may be suspended under section 14A-3-304.1 — so the obligation is enforceable even though the audit shows it is frequently not met. And an open permit is durable: it remains attached to the property record, and nothing about a change of ownership closes it or completes the inspections that were never done.
Why this record is so easy to miss
Three features of the system conspire to hide it.
First, inspection results for permitted work are not published as a dataset of their own. Department of Buildings inspection data reaches the public portal only where an inspection produced a violation. A reader searching the portal for inspections at an address will find the failures and nothing else, which makes a missing final inspection look identical to a quiet, uneventful one.
Second, the permit status field cannot be used as a substitute. The audit found 82.6% of permits still open as of December 2020, 72.5% with no associated inspection requests at all, and that the Department does not consistently close permits after required inspections are completed, with different divisions using the closed status differently. Neither open nor closed carries the meaning readers attach to it.
Third, the pattern looks like progress. Rough inspections appearing in a record feel like the beginning of a sequence that completed off-screen. In the audited sample, in 25 of 42 cases, it was the whole sequence.
