What Standard Plan Review proves
A permit issued through Standard Plan Review proves that City plan reviewers read the submitted drawings and checked them against the code before the work was allowed to start. Of the Chicago review routes it is the one that carries the most weight, and it still only establishes that the proposal was sound on paper.
Chicago does not run one permit process. It runs several, and which route an application took determines who, if anyone, actually read the drawings. Standard Plan Review is the ordinary full route for small to mid-size new construction and renovation: applications are filed through the Department's electronic plan system and assigned a project manager, and City reviewers across the relevant disciplines mark them up.
The distinction that matters to a reader is between a reviewed proposal and a verified building. Plan review happens before construction, against drawings. Nothing in it speaks to what was framed, wired or poured afterwards. That is the job of inspection, which is a separate record held separately and, in Chicago, frequently absent.
Where the route is recorded, and why it is the field to read
The route lives in a single field of the published permit data: REVIEW_TYPE, which the City defines as the process used to review the permit application. It sits in the Building Permits dataset alongside the permit number, type, work description, fee breakdown and location.
That field is the most useful thing on a Chicago permit record for the question a buyer is actually asking, and it is the one almost nobody reads. Two permits can look identical — same address, same work description, same issue date — and mean entirely different things depending on whether a City reviewer examined the drawings, a private professional certified them, or there were no drawings at all.
The City also publishes a guided search interface over the permit data as a Data Portal story, Building Permits Search (dmcg-xwb8). It is a search front end rather than a separate dataset, and it draws on the same records and carries the same limits.
What takes this route
The Department's Guide to Building Permits, published October 2019, describes Standard Plan Review as covering small to mid-size new construction and renovation, with stated eligibility of:
- buildings up to 80 feet in height;
- residential properties up to 49 dwelling units;
- commercial properties under 150,000 square feet.
Read those thresholds with their 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 reliable evidence that the route was bounded this way when the guide was written; they are not verified against the current code, and a permit from a different year may have been bounded differently.
Above those limits, work moves to the coordinated route for large projects. Below and beside them sit the over-the-counter route for work needing no drawings and the self-certification route, in which a private licensed professional certifies compliance and no City reviewer reads the drawings at all.
What the reviewers check, and what sits outside their review
Plan review is a code review of submitted documents by discipline — architectural, structural, mechanical, electrical, plumbing and ventilation, as applicable to the project. It asks whether what is drawn would comply if it were built that way.
Several checks that readers assume are part of it are separate gates:
- Zoning. Whether the use, unit count and bulk are permitted at that address is reviewed by the Zoning Administrator, not by building plan review. The Department's guide states most projects need zoning approval, and the permit data carries zoning fees as fields distinct from the building fees.
- Landmark status. Landmark buildings and buildings in Landmark Districts require approval from the Department of Planning and Development, the City department responsible for zoning administration, landmarks and development review.
- Construction. Nothing in plan review observes the site. A set of drawings approved by the City and a building built to those drawings are two separate propositions, connected only by inspection.
There is also the case where the permit arrives after the work. A permit obtained to bring existing unpermitted construction within the code is a legalization record, and plan review in that situation examines drawings of what is claimed to exist. The record looks the same as any other.
The City tracked these routes as separate programs
That the routes are genuinely different things is not an inference. The City published separate performance datasets for them, because it measured them separately: time to issue Standard Plan Review program permits (4ygs-9x34), time to issue Easy Permits (7ray-xvet), time to issue Developer Services permits (ijdy-a94t), and time to issue Green Permits (z2qz-687z).
These datasets are stale. Three of the four were last updated on August 4, 2014. They are evidence that the routes existed and were tracked as distinct programs; they are not current performance data, and the Green Permit program's present status could not be confirmed in current Department material. Anyone citing them as a measure of how the Department performs now is misreading them.
Reading one route against another
Because the route determines who read the drawings, the routes rank cleanly against each other on that one question, and a reader can place a permit on the scale as soon as the review type is known.
- Standard Plan Review — City plan reviewers read the drawings. Strongest review on the scale.
- Developer Services — City review for the largest projects, with part of the plan review potentially performed by third-party reviewers rather than by City staff. Strong, but partly private.
- Self-certification — an Illinois-licensed architect or structural engineer registered with the Department certified compliance and City plan review was skipped. Weakest review, same field inspection obligations.
- The over-the-counter route — no drawings were submitted, so nobody reviewed a method. It proves a fee was paid against a description of work.
One caution about naming. The permit data and the Department's current pages refer to an Express Permit Program, while the 2019 guide describes an Easy Permit Process. Whether these are the same program renamed could not be confirmed. Do not assume a record using one name means the same thing as a record using the other, and do not assume it means something different.
What a plan-reviewed permit still does not prove
Plan review sits at the strong end of the Chicago review scale, and the scale itself tops out well short of what a buyer wants. None of the four routes tells you whether the work was inspected. That is a separate record, and the City publishes no standalone inspections dataset — a passed inspection generally produces no public record at all, so the system is visible chiefly through its failures.
How thin the inspection record is was measured by the City's own watchdog. The Office of Inspector General's 2022 Audit of the Department of Buildings' Permit Inspections Process found 98.9 percent of required inspections completed on permits requiring a certificate of occupancy, against 16.7 percent of new construction permits that do not require one. In a targeted sample of 42 fully constructed buildings, 25 had rough inspections and no final inspections. The Inspector General's June 2024 follow-up found the Department had not implemented corrective actions.
So the honest reading of a Standard Plan Review permit is this: the strongest evidence Chicago's permit system produces about intent, and no evidence about execution.
