Week-one Chicago building permits: a South Side solar installer's route

Elena runs a two-person solar install crew out of Chicago's South Side, putting panels, racking and the occasional battery on bungalows and brick two-flats from Ashburn to Beverly. Her best leads come from blocks where a neighbor just pulled a solar permit, and from homeowners who are about to re-roof, because a new roof is the cheapest moment to add an array.

Yard signs and word of mouth worked, but slowly, and by the time she heard about a block it had already been canvassed by the big national installers. A brand-new city building permit is the earlier signal she wanted: Chicago requires one for rooftop solar and for re-roofs, and each permit lists the work address, the community area and the ward.

What changed

She bought ChiPermit for $19. After Stripe checkout, the CSVs were emailed directly from Armorlight: 7-day and 30-day files from the City of Chicago's public Building Permits dataset, with permit type, work type, work description, street address, community area name, ward, reported cost and issue date. The public file also carries contractor fields, but Elena uses ChiPermit to spot work addresses early, not as a contact list.

That week

• Mon: opened the 7-day file: 593 permits issued Oct 5 to Oct 9. She filtered the work-type column to Small-Scale Solar PV System and got 37 rooftop solar permits, every one of them through the city's Express Permit Program, which accounted for 400 of the week's 593.
• Tue: sorted the solar rows by community area. Ashburn had 5, Roseland 4, Garfield Ridge 3 and Beverly 3, right in the South Side and southwest bungalow belt she already drives. The citywide list is dominated by downtown and the North Side (Near North Side 52, Near West Side 34, Lake View 31, Loop 31), but very little of that is residential solar, so she skipped it.
• Wed: switched the filter to Reroofing: 40 re-roof permits that week, none at the same address as a solar permit. Those homeowners are about to put new shingles on, and she planned a door-hanger loop offering a free solar layout before the roofers finish, starting with the re-roofs in her community areas.
• Thu: opened the 30-day file for the bigger picture: 2,633 permits issued Sep 12 to Oct 9, 247 of them small-scale solar. She mapped the solar addresses by ward and booked her route block by block, leaving a short note for neighbors around each new install instead of cold-knocking whole streets.

The file became her weekly planning sheet: every new solar or re-roof permit on the South Side is a reason to be on that block this week, without buying a list or calling strangers.

Illustrative scenario: Elena is a composite operator, not a named customer. The permit counts, work types, community areas and dates come from real ChiPermit 7-day and 30-day files generated Oct 12, 2026 for the weekly refresh.
