California Historical Resource Status Codes
and Additional SurveyLA Status Codes

The California State Office of Historic Preservation has developed California Historical Resource (CHR) Status Codes as a standardized system for classifying historical resources in the State’s Historic Resources Inventory. These Status Codes are used statewide and are assigned to properties and districts by field surveyors as part of the survey process and when they are designated. CHR Status Codes are used in ZIMAS for the classification of designated historic resources. Click HERE for a complete list of the CHR Status Codes.
For purposes of the California Environmental Quality Act (CEQA), designated or eligible resources are considered “Historical Resources.” (PRC 15064.5(a))
