Request for Investigation

To request County help with investigation of a possible code violation is called a Request for Investigation (RFI). For any RFI, we will need some information from you in writing on a Request for Investigation form (PDF). Please call 209-966-5151 if you need information for completing the RFI form. You can mail, fax, or email the form (see below) and the Code Compliance Technician will contact you. Code investigation requests may be anonymous.

Assessor’s Parcel Number (APN) & Zoning

When inquiring about code standards or reporting possible violations, it is most helpful if you know the APN for the parcel you are inquiring about. We will try to help you find an APN if you don’t know it.

Many frequently asked questions require knowing the zoning of the parcel. Call 209-966-5151 to determine zoning. Zoning is not available online. Please call.
