Riverside County permit timing visualization. The primary fixed-denominator comparison includes every description-verified mature filing, including filings without recorded issuance. Production tract recorded issuance shares were 56.4 percent by day 180, 78.0 percent by day 365, and 86.2 percent by day 730. Detached ADU shares were 28.9 percent by day 180 and 63.6 percent by day 730; the one-year ADU cell is suppressed under the small-cell rule. Non-tract detached shares were 19.9 percent by day 180, 41.7 percent by day 365, and 62.4 percent by day 730. The main timeline follows the full mature cohorts from application day 0 through the same 730-day observation window. Half of all mature filings had recorded issuance by day 155 for production tract, day 330 for detached ADUs, and day 461 for non-tract detached homes. The ridge chart is secondary and conditional among mature filings with a recorded issuance within 730 days; filings without a recorded issuance within two years are excluded. Riverside anonymous records do not expose named department, station, or clearance review rows. The project destination is /sandbox.

Every filing had to earn its place.Work classes were only the candidate pool. We reviewed each public description, and every proposed keep received an independent second classification. We kept complete new-home construction—not remodels, additions, pools, roofs, mechanical work, or other mini-permits. The result was 10,921 production-tract, 275 detached-ADU, and 1,128 non-tract detached filings.

Start with the permits that made it through.Among mature filings with a recorded issuance within two years, the median was 134 days for production tract, 197 days for detached ADUs, and 265 days for non-tract detached homes. That limited view leaves out filings without a recorded issuance within two years; the main timeline puts them back.

Recorded-issuance timelines varied widely.This secondary ridge view includes only mature filings with a recorded issuance within two years. It shows their decile spacing and exact quartiles; filings without a recorded issuance within two years are not in these ridges.

Now count every mature filing. At six months, the pathways had separated.Every application filed by July 13, 2024 stays in the denominator, including filings with no recorded issuance.
Production tract homes: 56.4% (4,823 of 8,553).
Detached ADUs: 28.9% (35 of 121).
Non-tract detached homes: 19.9% (141 of 710).

At one year, production tract still led non-tract by 36.3 points.Production tract homes: 78.0% (6,674 of 8,553).
Detached ADUs: the one-year ADU cell is suppressed under the small-cell rule.
Non-tract detached homes: 41.7% (296 of 710).
06 / 07
Two years did not erase the gap.Production tract homes: 86.2% (7,369 of 8,553).
Detached ADUs: 63.6% (77 of 121).
Non-tract detached homes: 62.4% (443 of 710).
The first day at least half of every mature cohort had a recorded issuance was day 155 for production tract, day 330 for detached ADUs, and day 461 for non-tract detached homes—a 306-day gap between production tract and non-tract SFD.

The ordering holds. The reason remains hidden.Production tract stayed above non-tract SFD at every timing window in the 2021–2023 mature filing years and the partial 2024 mature cohort. Equal tract weighting produced 64.7%, 84.6%, 91.0%; removing the largest inferred tract produced 57.6%, 79.5%, 88.2% at 180, 365, and 730 days. Riverside's anonymous records do not expose named department, station, or clearance review rows. This observational comparison shows when recorded issuance happened; it cannot establish causality or explain why one pathway moved sooner.
