Chicago building permits: look up any address

Type a Chicago address to resolve it to its parcel and see its building-permit history — what was permitted, and when. Below: what permits tell you and where the data comes from.

Reading a block by its permits

A building permit is the City’s record that it authorized work at a parcel — new construction, a gut rehab, a porch, a demolition, electrical or plumbing. Each carries a date, so a run of permits on one block is often the earliest public signal that money is moving into an area.

Enter an address and Civic Worth resolves it to its parcel and surfaces the permit history on the parcel page, alongside the parcel’s zoning, ward, assessed value, and 311 activity — the full public record in one place.

Source: City of Chicago building-permit data, resolved to the parcel and timestamped. Confirm the authoritative record with the City of Chicago Department of Buildings.
