Collection last successfully checked Nov 2, 2026, 9:01 a.m. ET. This report updates when the retained records change.
Administrative and unclear-scope records, renewals and records absent from the current source are excluded. Each permit counts once; one project may have several permits. Issue / ready dates do not establish construction starts. Estimates are applicant-reported whole-job estimates, not company revenue or trade contract values. Zero and missing estimates are excluded from the median.
