Building and trade permits the City of Columbia issues inside city limits for homes and other non-commercial work: new houses, duplexes and townhouses, home alterations and additions, re-roofs, heating and cooling, electrical, plumbing and gas, residential solar, decks and foundation repair. Commercial building permits, right-of-way and utility permits, fire systems, signs and grading in the same file are not counted, and neither is unincorporated Boone County, which issues its own permits.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
