Data through September 2026 · updated 23 Oct 2026
The usual permit in unincorporated Riverside County takes 117 days from issue to the county's final inspection; the middle half take 47 to 231 days. That is from 11,057 permits issued Oct 2024–Sep 2025 that reached a final. Roofing permits are quickest at 37 days; ADU and casita permits take longest at 365 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 county to approve the plans. Ask the county for its current review times.
Finishing the work (measured here): issue → final. From the day the county 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.
