Riverside County new-home permit timelines. We classified Riverside County residential permits whose current status is Issued or Final, with a formal building application on or after January 1, 2022 and recorded issuance through July 10, 2026: 592 ADU, 7,861 tract home, and 518 single-family home permits. Timing begins at each project's earliest confidently matched public intake — often an online application — so it covers the full journey, not just the formal application. Medians were 148 days for tract homes, 182 days for ADUs, and 290 days for single-family homes. The middle half spanned 82–261 days for tract homes, 88–328 days for ADUs, and about 189–467 days for single-family homes. The main timeline shows a typical single-family permit at the 290-day median: over half begin with an online application accepted a few weeks later, then Riverside's own review statuses — accepted, corrections rounds, approved — are placed at illustrative positions, with typical companion cases (a fire review, grading, fire sprinklers, and mitigation fees) drawn alongside without dates. Riverside does not anonymously expose dated department, station, or clearance reviews, so status and companion-case positions are illustrative, not measured. This issued-only comparison cannot describe permits that never issued. Riverside's records show when issuance was recorded—not why one type moved sooner. The project destination is /sandbox.
