Data through September 2026 · updated 20 Oct 2026
The usual permit in the City of Centennial takes 36 days from issue to the city's final inspection; the middle half take 13 to 97 days. That is from 5,853 permits issued Oct 2024–Sep 2025 that reached a final. Fence and wall permits are quickest at 0 days; new home permits take longest at 224 days. This is the time to finish the work and close the permit, not the wait for approval.
“How long does a permit take?” can mean two waits. This page measures the second one.
Getting the permit (not measured): application → issue, the wait for the city to approve the plans. Ask the city for its current review times.
Finishing the work (measured here): issue → final. From the day the city issued the permit to the day it recorded the final inspection. We count only permits issued Oct 2024–Sep 2025, at least 12 months before the file ends, so slow jobs have had time to finish; a permit still open is not in the days.
Permits issued Oct 2024–Sep 2025. Usual days is the middle permit among those with a final date: half finished sooner, half later. Middle half is the range the middle 50% fell in. Kinds of work with fewer than 100 permits in that period are left out.
