Riverside County, CA Building Permits: Who Issues Them
How Riverside County, CA building permits work: the county department that covers unincorporated land, which cities run their own, and how to look up records.
Riverside County is large and heavily incorporated, so the county building department covers only part of it. Before you apply for a permit or look one up, you need to know whether the address is in the unincorporated county or inside one of its many cities. Here is who issues building permits in Riverside County, what the county covers, and how to find the records.
Who Issues Building Permits in Riverside County?
Building permits for unincorporated Riverside County are issued by the county's Building and Safety department, which sits within its Transportation and Land Management Agency. It reviews applications against the adopted building code, issues permits, and inspects the work through final sign-off. It is the authority having jurisdiction for land outside any city. For more on that role, see our guide to the AHJ.
The county runs an online system called PLUS, its Public Land Use System, for permit submittals, along with a public permit lookup. Contractors and owners submit and track applications through the portal, and anyone can search records through the public tool.
The County vs. the Cities Inside It
This distinction matters more in Riverside County than in most places. The county department only handles unincorporated territory. The county's incorporated cities each run their own building departments and permit everything within their limits.
Riverside, Corona, Moreno Valley, and Temecula all operate their own building departments, and they are only a few of the county's many cities. A permit pulled in any of those cities will not appear in the county's records. Always confirm whether the address is inside a city or in unincorporated county land before you apply or search.
How to Look Up Permits in Riverside County
Start with the official source that matches the jurisdiction. For unincorporated property, the county's public permit lookup lets you search records without an account. For property inside a city, use that city's own portal. For a single property, the matching official record is authoritative.
For a wider view of what is being permitted across the county, our live Riverside County permit tracker pulls the county's residential filings every week and summarizes the busiest permit and trade categories. These records are open to the public by law. See are building permits public record for the background.
Permit Activity in Riverside County
Riverside County runs a solid volume of residential permitting. Permit Ledger tracked about 1,200 residential permits in the county in the trailing 30 days as of mid-July 2026, a bit below the roughly 1,300 tracked in the prior 30-day period. That count covers renovation, remodel, addition, solar, and pool work.
A modest dip like this from one period to the next is routine and points to demand staying near its recent level rather than a real slowdown.
Who Uses This Data
County permit data is a working tool for several groups: roofing, remodeling, HVAC, and solar contractors use fresh filings as high-intent leads; investors track active projects and stalled permits; and direct mail marketers build address lists from recent renovation activity. Because the records are public, anyone can use them. To research a single address, see how to look up permit history by address.
