Cook County Permit Ledger: who is pulling roof, solar and gutter permits.

This brief reads the public permit records for Cook County (the county assessor's permit file) and the City of Chicago (the city permit feed), aggregated by township and by applicant over the twelve months from 2025-09-06 to 2026-09-06. A permit filing is a public record of permitted work — it is not evidence of completed work, roof condition, or market share.

How to read this

Counts are permits FILED per township and applicant in the window, grouped by month of issue. An applicant is shown only when the name reads as a business; individuals and associations are aggregated into the township total and never listed. A permit filing is a public record of permitted work, not evidence of completed work, roof condition, or market share.

Counts are contractor-labeled contacts (contact_N_type containing CONTRACTOR, e.g. GENERAL CONTRACTOR, CONTRACTOR-ELECTRICAL) on Reroofing / Small-Scale Solar PV System permits filed in the window, keyed by community_area number; one permit counts once per distinct contractor name. The feed exposes no community-area name column, so no community_area_names map is included.
