Find My Zoning District
1. You will need the 9-digit APN (0XX-XXX-XX0) for the property. The GIS Database may not be able to find property-specific information by address.
2. Go to the GIS Database.
3. Enter the APN in the box in the top left corner of the screen. Click “GO”.
4. Click on the white APN number in the “Features Selected” box once it appears. Your parcel will be outlined in red.
5. In the “Map Layers” box on the right, scroll down to the end of the list and click on the “Zoning” box. The zoning is shown in a particular color, mouse over this color in an area just outside of the parcel highlighted for the Zoning District(s) that apply to the parcel.
6. To access a Parcel Map and other property information, click on "View Assessor Data and Maps" in the “Features Selected” box.
Understanding Zoning Districts
Now that I have the Zoning District(s) for my property, what does it mean?
A parcel may have only one Zoning District (e.g., “RM”, “TPZ”), may have 2 Zoning Districts layers (e.g., R-1/S-101) or may have several Zoning Districts layers (e.g., R-1/S-17/DR/CD). Each “layer” represents a distinct chapter or section in the County’s Zoning Regulations. Please find each layer of your Zoning District in the Zoning Regulations, as development will be required to comply with the regulation for each district.
As a rule of thumb, “S” districts contain development standards (e.g., setbacks, height, FAR, lot coverage), “R” districts are primarily residential in use, “RM” “TPZ” and “PAD” districts are rural, the “CD” district applies to all areas of the Coastal Zone, and the “DR” district requires compliance with design review standards.
