Classification scopeClassification precision for Residential Alteration in Chicago measured 97.92% on 2026-07-23 — below our ≥99% certification bar. Mixed-use leakage: ground-floor retail/office in buildings classified residential. 2.08% is an upper bound (some token false-positives). The permits are shown with that caveat.

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 Alteration — 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.
