How do I determine where my property lines are?

You may find approximate locations of your property lines on Diamond Bar’s GIS Parcel Data Map or you may obtain a copy of the parcel map from the L.A. County Assessor’s Office website. However, the exact location of your property lines can only be verified by a licensed surveyor. The City cannot recommend any specific surveyor or survey company.  You can search for California-licensed professional engineers and land surveyors by visiting the California Department of Consumer Affairs website.
