What a Developer Services permit proves
A permit issued through Developer Services proves that a large or complex project received a coordinated City review of its drawings before work was allowed to begin. It is the most managed of Chicago's permit routes and, like every one of them, it examines a proposal rather than a building.
Chicago does not operate a single permit process. It operates several, and the route an application took determines who read the drawings and how closely. Developer Services is the route for projects too large for the ordinary queue: the Department's guide describes it as covering buildings over 80 feet, residential buildings with 50 or more dwelling units, and foundations 12 feet or deeper. The process begins with an appointment request and is managed through to issuance.
For a reader assessing a large Chicago building, that is meaningful. It means the drawings went through a review with staff assigned to it, rather than a counter transaction. It does not mean anybody confirmed the building matches them.
What takes this route, and the caution on the thresholds
The stated scope comes from the Department's Guide to Building Permits, published October 2019:
- buildings over 80 feet in height;
- residential buildings with 50 or more dwelling units;
- foundations 12 feet or deeper.
Those figures carry a date. The guide states its code information is correct as of July 2017, and the Chicago Construction Codes became mandatory for most permit applications on August 1, 2020. The thresholds are good evidence of how the route was bounded when the guide was written and are not verified against the current code. A project at the boundary in one year may have taken a different route in another.
Below these thresholds sits Standard Plan Review, the ordinary full route in which City plan reviewers examine the drawings. Beside it sits self-certification, in which an Illinois-licensed architect or structural engineer certifies compliance and City plan review is skipped — a route whose own eligibility rules exclude new construction and additions over 30,000 square feet, buildings over four stories and over 55 feet, and work in existing buildings over 80 feet without written pre-approval. The buildings that take Developer Services are, by definition, outside the self-certification route entirely. That is a real and checkable distinction between classes of large building.
The part of the review that is not the City
One feature of this route changes what the record means, and it is easy to miss. The Department's guide states that third-party plan reviews carry an added cost. Part of the plan review on a large project may therefore have been performed by a private third-party reviewer rather than by City staff.
For a records reader this cuts both ways. Third-party review on complex projects is ordinary practice and often brings specialist expertise the Department does not hold in-house. But the resulting review is a private work product. The reviewer's report is not part of the public permit record, so a reader can establish that the route involved third-party review in principle without being able to see what that reviewer found or required.
The same applies to the structural peer reviewer's report that appears elsewhere in the Department's rules for complex work. These are documents whose existence is provided for and whose contents are not published.
Where the route is recorded
The route is stored in one field of the City's published permit data: REVIEW_TYPE, defined by the City as the process used to review the permit application. It is the single most useful field on a Chicago permit record for the question of who checked the drawings, and it is the field almost nobody reads.
The City also tracked this route as a distinct program. A Data Portal dataset, Performance Metrics – Buildings – Time to Issue Developer Services Permits (ijdy-a94t), exists alongside equivalents for the Standard Plan Review program (4ygs-9x34), Easy Permits (7ray-xvet) and Green Permits (z2qz-687z). Three of those four were last updated on August 4, 2014. They establish that the routes were measured separately. They say nothing about how the Department performs now, and the Green Permit program's current status could not be confirmed in Department material.
The Department also describes a Homeowner assistance service for owner-occupants of single-family homes needing help with plans. That is assistance rather than a distinct review standard, and it is at the opposite end of the system from this route.
The inspection question, which this route does not settle
No Chicago permit route records whether the work was inspected. Inspections are a separate record, and the City publishes no standalone inspections dataset — a passed inspection generally leaves no public trace, so the system is visible mainly through its failures.
Under the Municipal Code of Chicago, Section 14A-5-502.3, the duty sits with the permit holder: the permit holder must notify the building official when work done pursuant to a permit is ready for inspections. The City does not initiate the inspection. The Office of Inspector General's 2022 Audit of the Department of Buildings' Permit Inspections Process found that the Department scheduled inspections for 91.5 percent of the construction inspection requests it received in 2017 through 2019 — the Department responds when asked — while 72.5 percent of permits had no associated inspection request at all.
The audit's central split was not by review route but by whether a permit required a certificate of occupancy, the document the City issues when a building may lawfully be occupied. For permits requiring one, 98.9 percent of required inspections were completed and 97.2 percent received passing marks. For new construction permits that do not require one, 16.7 percent had all related inspections completed. The report identifies single-family homes and two- or three-flats as the buildings that do not require a certificate of occupancy — which is to say, the opposite end of the building stock from the projects this route handles.
That is the most favourable thing the public record supports about large buildings in Chicago: they generally fall in the class for which the inspection record is strong, because occupancy itself depends on it. It is an inference about a class, not a fact about any particular permit.
How to read one
A Developer Services permit, read honestly, establishes a short list:
- the project was large or complex enough to fall outside the ordinary routes;
- a coordinated City review of the drawings took place, possibly including third-party review whose contents are not public;
- zoning was reviewed separately, as it is on every route, by the Zoning Administrator and the Department of Planning and Development;
- the fee position is recorded, and the City states work may not begin until the applicable permit fee is paid.
And a shorter list of what it does not establish: that the building was constructed as drawn, that required inspections were completed, or that the permit still stands. The published permit data excludes permits voided or revoked after issuance, so revocation removes a record rather than marking it.
The Inspector General's June 2024 follow-up found the Department had not implemented corrective actions on the 2022 audit's findings. Nothing in the intervening period has made a permit record a substitute for an inspection record.
