CMap: Mapping your Clackamas Property

CMap is Clackamas County’s tool for looking up property information. With an address, parcel number, tax lot or intersection you can find:

  • Building information
    A home’s square footage, the number of bedrooms and bathrooms, the year it was built and when it last sold.
  • Tax Information
    A building’s value, land value, total value and assessed value.
  • Jurisdiction
    Is this property in a city? Is it part of the urban growth boundary? Are there any zoning restrictions?
  • Voting
    Know your State House and Senate district, voting precinct and congressional district.
  • Services
    Find out who provides services such as cable, garbage, fire, sewer and water — as well as local schools and parks.
  • Natural Hazards
    Floods, earthquakes, fires and landlsides — which naural disasters are most likely to affect your property.
  • Documents
    Find surveys and taxmaps provided by the Surveyor and Tax Assessor.

Tips for How to Use CMap

  • Use the search box to enter an address. You can use the down arrow to select another search option — like city, intersection, tax lot or parcel number.
  • Use the plus (+) and minus (-) icons on the bottom left-hand side to zoom in or out.
  • Clicking on the camera will turn on/off the aerial photography.
  • Not what you’re looking for? We also have a tool to look up your property tax information, AscendWeb.
