Corona building & ADU permits
Recent permit activity, updated continuously.
Corona sits in Riverside County at the western edge of the Inland Empire, where California's ministerial ADU framework and SB-9 lot splits both apply. The city's CorStat portal uses a dedicated "Single Family ADU" permit type — and records whether the unit is detached or attached — so Igni reads the ADU type straight from the source instead of inferring it.
Igni is tracking 258 residential and building permits in Corona, CA — including 29 classified accessory-dwelling-unit (ADU) filings. The most active ZIP is 92882. The most recent filing Igni tracked was Sep 29, 2026. All records come from corstat.coronaca.gov (Socrata), an official government open-data feed, and are refreshed continuously.

Counts are permits issued per calendar month as Corona publishes them to its open-data feed — not a complete census; a change in what the city publishes moves them too. The current month is left out, and the most recent months are provisional. A forecast is a statistical estimate with a range, not a prediction for any project. Informational only.

Typical, not guaranteed: individual permits vary with project scope, application completeness and plan-review workload. Days are calendar days from application to issuance; applications still pending are counted as not-yet-issued rather than dropped. Informational only, not legal advice. How we calculate approval times.
Housing law — California
California mandates ministerial (by-right) approval of accessory dwelling units statewide, with a 60-day decision deadline and one ADU plus one junior ADU allowed on most single-family lots; owner-occupancy is generally not required.
SB 9 allows by-right duplexes and urban lot splits on single-family lots, and newer transit-oriented upzoning (SB 79) phases in from 2026.
