Chicago Permit Lookup — Direct Portal Deep-Link
Chicago DOB Building Records is the city’s official portal for every building permit, electrical permit, plumbing permit, mechanical permit, demolition permit, and inspection across all 77 community areas. The system pulls from the same database DOB inspectors and plan reviewers use day-to-day. We deep-link you there directly.
Opens on webapps1.chicago.gov — official City of Chicago domain.
What you can look up
The Chicago Building Records portal accepts address-based search and surfaces three categories per parcel: Permits (every permit ever pulled, with applicant, contractor, valuation, and issue date), Inspections (pass/fail outcomes per permit), and Violations(DOB-issued violations, often paired with the building court docket number). The portal also links to the Department of Buildings’ underlying scanned permit drawings — for many post-2000 permits, you can download the actual plan PDFs free. That’s a feature most cities don’t offer. For pre-2000 records, microfilm exists at the DOB records counter at City Hall.
How to read Chicago permit codes
Chicago permits use a clear “Permit Type” field. The most common types you’ll see: EASY PERMIT (small repairs under $20K — no plan review), STANDARD PLAN REVIEW (mid-size remodels with architect-stamped plans), NEW CONSTRUCTION (new build), RENOVATION/ALTERATION (substantial interior or addition work), WRECKING/DEMOLITION (tear-down), SIGN, SCAFFOLD, PORCH. Chicago’s porch permit category is unique — after the 2003 porch collapse, the city created a standalone permit category with stricter inspection rules. SELF-CERT on a permit means an Architect of Record stamped that the design meets code without DOB plan review. Inspection results read as Passed, Failed, Conditional (passed with corrections required), or Not Ready(inspector arrived but the work wasn’t at the inspection stage). A long string of Not Readyoutcomes signals a contractor who’s scheduling inspections to game the open-permit clock.
Red flags to watch for
Chicago’s biggest red flag is the open building court docket — when DOB violations escalate, they go to the Department of Administrative Hearings or actual building court. The docket number appears in Building Records, and you can pull the full case from the Cook County court system. Buildings with active court cases can carry liens and judgment amounts the seller may not disclose. Second: Easy Permits stretched into substantial work— because Easy Permits skip plan review, contractors sometimes file an Easy Permit (e.g. “repair drywall”) and then do an entire kitchen gut. The valuation field will be suspiciously low for the visible work. Third: Conservation District / Landmark District properties — Chicago has 60+ landmark districts and Conservation Districts where exterior changes need Commission on Chicago Landmarks review. A standard permit on a landmarked property without a Landmarks ticket is a red flag. Fourth: multi-flat conversions— Chicago’s two-flats and three-flats are zoning-protected; a permit converting a two-flat into a single-family without an explicit zoning approval is a future code-enforcement case. Fifth: open porch permits. Porch permits expire harshly in Chicago and an open one is a recurring nuisance.
Questions LA homeowners actually ask
Yes. The Chicago DOB Building Records portal only covers properties inside the City of Chicago limits. Suburbs in Cook County (Oak Park, Evanston, etc.) each maintain their own permit system, and unincorporated Cook County uses the County Building & Zoning portal. Always confirm jurisdiction first.
AskBaily does not scrape Chicago DOB
We have no Chicago DOB database mirror, no scraped permit cache. The deep-link above is the entire integration — the homeowner reads the City of Chicago record on the City of Chicago system. That is the only way to know what is actually on file.
