How these numbers are made

Source: City of Centennial ArcGIS Server, EPL_Permit (EnerGov permit table), read 20 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.

Building, trade, fence and sign permits the City of Centennial issues inside the city limits only. Homes with a Centennial mailing address in unincorporated Arapahoe County, and the neighbouring cities of Greenwood Village, Littleton, Englewood, Lone Tree and Aurora, get their permits elsewhere and are not in this file.

  • The city's file names no contractor, so there are no contractor lists, rankings or firm pages for Centennial.
  • The value is the valuation declared on the permit, which sets the fee. Many over-the-counter home permits list none or a nominal figure, so values are a guide, not a cost.
  • Hailstorms drive roofing: a storm season can double a month's permits, so roofing counts swing from year to year.
  • The city's broad 'Misc' class (EV circuits, sewer repairs, furnace swaps, siding) is sorted into trades from the short work description; anything left is a remodel or repair.
  • Homes are permits the city files as residential. Multi-family buildings and commercial work count as other.
  • A final date is the date the permit was finaled. Right-of-way, temporary use and development permits are left out.

Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
