Classification scopeWe measured Residential Solar in Chicago on 2026-06-06: 20 of 20 sampled permits were correctly classified (100%). At that sample size the 95% confidence interval is 83.9%–100.0%, which spans our ≥99% certification bar — so this cohort is not certified, and not shown to have failed. It is measured and indeterminate. The permits are shown; the classification is the part we stand behind hardest, and this is what we currently know about it.

Classification coverageOf 867,206 permit records we hold for Chicago, 358,814 (41.4%) carry the work markers our cohort rules need — the rest are published without a residential/commercial signal we can classify on. Of those, 358,251 (99.8%) are placed in a cohort. Certification measures whether that placement is right — not how much of the corpus reaches it.

Why this list is real

These contractors are ranked from classified permits, not keyword scrapes. We read each permit’s work-type, scope, and occupancy fields to place it in Residential Solar — so a filing that looks like a generic alteration lands in the right segment, and the ranking reflects real work. When the fields don’t support a confident call we mark it Unclassified — we never force a wrong segment to pad a contractor’s count.
