GIS Parcel Data

The County of San Luis Obispo is engaged in a current project to bring Geographic Information Systems (GIS) parcel maintenance in-house to the Assessor's Office. However, until then we are unable to distribute these data.

Please contact ParcelQuest, owner of these data, to obtain a copy. If you are a contractor working for a County department, please provide them with your County point of contact for the project. We thank you in advance for your understanding.
 

County of SLO GIS Open Data Site

The County of San Luis Obispo Geographic Information Systems (GIS) teams are committed to providing transparency and easy access to as many GIS datasets as possible. To support this mission, they created an Open Data site through arcgis.com, which is the data repository for all publicly available SLO County GIS Data.
