PortlandMaps


Our Mission

The City of Portland is providing PortlandMaps.com as a new way of accessing public data. This data has always existed and been obtainable by any public citizen, but processes for finding and retrieving it have either been too complex or not well known by the average individual.

Our mission is to provide up to date public information in a easy to use interface. Letting everyone have access to the information, not just the experts.

Data

A wide variety of data is available for the Portland Metropolitan Area, a few of these datasets are listed below.
  • Assessor/Tax Lot Information
  • Aerial Photography
  • Building Footprints*
  • Building Permits*
  • Census
  • Crime Data*
  • Elevation
  • Parks*
  • Mass Transit
  • Natural Hazard
  • Schools
  • Urban Growth Boundary
  • Underground Storage Tanks*
  • Water/Sewer*
  • Zip Code
  • Zoning Maps*
* Data available for Portland only

Traditionally, these datasets all needed to be obtained from multiple sources, in many different formats. Now, using our service, you can get all of the information through a single application.

Privacy

All information provided through our service is available through traditional public channels. We have, however, limited the information we provide to protect individual's privacy. Because of this you will not find phone numbers of individuals in any of our public databases. If you require access to this information, you will have to go through traditional methods. Please refer to the PortlandOregon.gov Privacy Policy for more information.

Owner Name Information: For more information regarding how to change the property ownership name, please contact Multnomah County Assessment, Recording & Taxation at (503) 988-3326 or Assessment & Taxation. The Division�s Ownership Section can also review requests to remove a name based on some limited public safety provisions.

Suggestions and Comments

Our service has been designed to be very simple and easy to use, while providing the most flexibility possible. If you have any comments or suggestions about our service, please e-mail us at webdev@portlandoregon.gov.
