This system is a directory of scanned images of property surveys done in the County of Marin, filed with the Department of Public Works, and prepared by licensed surveyors, who are solely responsible for the accuracy of the surveys. The surveys were generally done to identify the corners of parcels within the county. Images are indexed by a three digit Map Book number (the first three numbers of a parcel number). All images are in a .tif file format.
Pursuant to California Business and Professions Code Section 8773, persons authorized to practice land surveying in the state have file with the County Surveyor the following written record of corner(s) established or restored.
Only Map Books with a property having a corner record are listed. Specific questions on corner records can be directed to the County Surveyor via the DPW Contact Page.
