Why this matters
Permits are issued and inspected by the city or county where your property is located, and you will need to select the correct jurisdiction when submitting your application.
Important: Submitting under the wrong jurisdiction will result in permit cancellations. Symbium service fees are non-refundable, and permitting fees may also be non-refundable.
How to verify your property’s jurisdiction
-
Use Symbium. If your address appears under a selected jurisdiction in Symbium, you can be confident that the property is located there.
If you cannot find your address, you may be searching in the wrong city or county. Keep in mind that the postal city in a mailing address does not always match the property’s actual jurisdiction.
-
Check your planset. Jurisdiction is often listed directly on your plan's cover page.
-
Check county assessor’s or GIS records. Typically counties provide:
- jurisdiction information directly in the search results, or
- a map showing incorporated boundaries.
Here are some official resources for commonly requested California counties:
- Los Angeles County Assessor’s map search
- Marin County MarinMap search
- San Mateo County Property Maps Portal
- Kern County Assessor Property Search
Can’t confirm the jurisdiction?
Contact the city and/or county where the property is located. They are the official source for the most up-to-date property and jurisdiction information.
