whats my zoning

What's My Zoning is a tool to help you find the zoning designation for parcels within the unincorporated areas of Ventura County.

Enter the first 9 digits of your 10 digit Assessor Parcel Number (APN).

Do not enter any dashes or spaces between the digits.

Press the submit button (Do Not hit the ENTER/RETURN key). A new window will appear showing you your parcel and the zoning designation your parcel falls within.

Note: If you don't know your APN, please click here to be taken to the County Tax Collector's website. You'll be prompted to enter your address, then to click the SEARCH button. Your APN will be provided if it exists in our database.

If you are unable to determine your APN, please contact the Assessor's Office at (805) 654-2181.
