Zoning Database (OZD)
The Sonoma County Permit and Resource Management Department (PRMD) maintains an Official Zoning Database (OZD) in digital form. The OZD was adopted by the Board of Supervisors on June 12, 2007 and became official on July 12, 2007. This zoning database was created using Geographic Information Systems (GIS) mapping software and replaces all hard-copy zoning maps that were formally located in the self-help lobby at PRMD.
The reports provided below are generated from the OZD and contain zoning sorted by Sonoma County Assessor’s Parcel Number (APN). These reports are updated as needed at the end of each month, so you should contact the PRMD Planning Information Phone to verify current zoning before making decisions.
Within these reports, both “Base Zoning” and “Combining District” (aka overlay) are listed. When indicated, a Combining District may be Biotic Habitat (BH), Scenic Resources (SR), Flood Zones (F1 or F2), etc. Combining Districts are site specific and most likely do not follow APN boundaries. It cannot be determined where on the APN the Combining District is located from these reports. For information on Combining District boundaries, please contact the PRMD Planning Information Phone.
A complete description of Zoning and Combining Districts can be found in the current zoning code regulations area of this site.
You can locate the zoning for a specific property by using either the APN or street address.
How to find zoning by APN:
Click on the Assessors Parcel Map Book Number range to open the report. Perform a search (using the toolbar button which looks like a pair of binoculars) for the APN, including hyphens.
How to find zoning by Address:
To perform any other search within the database, you must download and open the complete document available at the bottom of this page. This is only recommended for those with a DSL, cable or T1 connection. Once you download the document, perform a search (using the toolbar button which looks like a pair of binoculars). Type in the street number and/or name. Do not include the street type (Road, Avenue, etc.).
These documents are saved in Adobe Acrobat format.

|Although every effort is made to provide complete and accurate information on this website, users are advised to contact appropriate PRMD staff before making project decisions. This may involve contacting more than one section within PRMD (e.g. Building, Plan Check, Zoning, Well & Septic, etc.), since each section implements specific codes or ordinances which may affect your project.|
