Lake County Map Viewer - requires Adobe Flash
Adobe Flash can be downloaded at no cost from the Adobe web site. Please note, the "Free! Google Toolbar" is not required to run Map Viewer, and can be deselected before downloading Adobe Flash.
**NOTE: The Map Viewer applications depend heavily on the browser cache. If you are having problems getting the maps to load, try clearing your cache (Tools – Options).
New Maps for iOS
This new parcel lookup/viewer application will work on desktop as well as most mobile devices, including iOS. It runs in your browser, no Flash required.
Please keep in mind that this is a brand new application – both to Lake County and to the developer, ESRI. It is a work-in-progress. Currently, custom options are very limited, but as ESRI makes improvements on their end, we will update the application on ours.
- Click the “APN” tool at the top to search for an 8-digit parcel number

The information displayed on this site should be considered an Advisory Tool Only, to be used for land use planning, education, general hazard awareness and general information. The parcel boundaries shown are an attempt to create a seamless county-wide layer and therefore do not necessarily represent a parcel boundary as reflected in a legal description. Discrepancies in parcel acreage, shape and location are common. The information given is not the legal document to be used in single site determinations. To obtain a legal description of a parcel, please consult your deed or contact the Lake County Assessor/Recorder at (707) 263-2302.
