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 Commercial 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.

FAQ

Frequently asked about commercial alteration permits in Columbus

How many commercial alteration permits are pulled in Columbus each year?
56,696 commercial alteration permits are currently indexed for Columbus. Volume varies year over year; PermitCore tracks both historical totals and current rolling-window activity.
Where can I see the latest commercial alteration permits in Columbus?

How is the commercial alteration data in Columbus refreshed?
PermitCore rebuilds the Columbus index nightly. The underlying municipal source publishes on its own cadence, which varies by jurisdiction, so each page stamps its own freshness (the "as of" date) rather than promising a fixed interval — and a stale source is marked as such. Segment classification is applied automatically by PermitCore's classification engine; field-level data-quality flags surface inline so you can filter for clean rows.
