Building Permits

Note, 10/15/2025: We have added a PERMIT_CONDITION column. This dataset includes information about building permits issued by the City of Chicago from 2006 to the present, excluding permits that have been voided or revoked after issuance. Most types of permits are issued subject to payment of the applicable permit fee. Work under a permit may not begin until the applicable permit fee is paid. For more information about building permits, see http://www.chicago.gov/permit.
