Parcel Viewer
King County Parcel Viewer is an online mapping tool that helps residents, property owners, researchers, and businesses access parcel information through an interactive map. This article explains how the Parcel Viewer works, how to search for properties, what information appears after selecting a parcel, how it connects with other King County property systems, and which government offices handle related property information.
Purpose of King County Parcel Viewer
The King County Parcel Viewer provides an easy way to search for parcel information without starting with a paper record request or visiting a government office. The tool allows users to locate parcels by address, parcel number, or by selecting an area directly on the map.
The official King County Parcel Viewer page explains that users can search for parcel information, select a parcel, and access direct links to related property reports. The service is operated through the King County GIS Center and is designed for property research using geographic information system (GIS) mapping.
Parcel Viewer is commonly used when someone needs to identify a property location, review basic parcel details, connect to assessment information, or understand related district and development information associated with a property.
How Parcel Viewer Searches Work
Parcel Viewer provides several ways to locate a property. Users do not need to know every property detail before beginning a search. The available search methods allow different types of users, including homeowners, researchers, and professionals, to start with the information they already have.
Address Searches
An address search allows users to locate a property by entering a street address. This option is useful when someone knows the physical location of a property but does not know the parcel number.
After locating an address, users can select the parcel on the map to view available parcel information. Selecting the parcel is necessary to access the property details and report links connected to that parcel.
Parcel Number Searches
Users who already have a parcel number can search directly by that identifier. A parcel number can provide a more specific way to locate a property because it identifies a particular parcel in King County property records.
The Parcel Viewer search results connect selected parcels with related reports, including the King County Assessor’s eReal Property report and the Districts and Development Conditions report.
Map-Based Selection
Parcel Viewer also allows users to zoom in on the map and click directly on a parcel. This option can help when researching an area, comparing nearby properties, or locating a parcel without a known address.
The interactive map displays parcel information after a selection is made. Users can view the selected parcel details and access related property reports from the available links.
Information Available for Selected Parcels
After selecting a parcel, Parcel Viewer displays information connected to that property. The map application provides access to several details that help users understand the parcel and identify additional government records.
Available parcel information may include:
Parcel number
Address
Present use
Property name
Jurisdiction
Taxpayer name
Appraised value
Lot area
Levy code
Number of units
Number of buildings
Parcel Viewer also provides links to related reports from other King County systems. The information displayed in Parcel Viewer connects users to additional property records rather than replacing those separate systems.
Related Property Reports
Assessor eReal Property Report
Selected parcels include a link to the King County Assessor’s eReal Property report. This report provides additional property information through the Department of Assessments’ property information system.
The eReal Property system can be searched by address, parcel number, or condominium and apartment complex name. It is designed for users who need property information without necessarily viewing the property on a map.
Districts and Development Conditions Report
Parcel Viewer also connects users to the Districts and Development Conditions report provided through the King County GIS Center. This report includes information related to electoral, planning, and administrative districts and designations.
The report can help users identify government districts and planning information associated with a property. Parcel Viewer search results and eReal Property reports both provide links to this information.
Parcel Viewer Map Features
The Parcel Viewer application includes interactive mapping features that allow users to view parcel boundaries and explore property information visually.
The official King County Parcel Viewer application includes search tools, map layers, printing options, and parcel selection features. Users can search by address or parcel number, view map layers, and select parcels directly from the map.
Map Layers and Basemaps
Parcel Viewer provides map display options that allow users to view different background maps and property-related layers. These tools help users examine parcel locations and surrounding areas.
Users should remember that parcel boundaries shown in the application are approximate and are not for legal use. Property boundaries displayed on the map are intended for information and research purposes.
Printing and Sharing Maps
The Parcel Viewer application includes tools for printing and sharing map information. These features can help users save a view of a property location or share a map reference with others.
Printed or shared map views should be used as informational materials. Official property records and legal documents should be obtained through the appropriate King County office or record system.
Parcel Viewer Limitations
Parcel Viewer is a research and mapping tool, not a replacement for official legal records. Information displayed through the application helps users locate properties and connect with related government reports, but users should rely on official records from the responsible department when they need certified or formal documentation.
Users should also be aware that map parcel lines are approximate and should not be used as legal property boundaries. Questions involving ownership, recorded documents, or official assessments may require information from other King County departments.
King County GIS Center Role
The King County GIS Center manages geographic information services and provides mapping applications, including Parcel Viewer. The GIS Center supports public access to geographic data and property research tools.
The GIS Center also provides other mapping resources, including King County iMap, which allows users to view and customize geographic information from across the county.
Property Research Tools
King County provides several connected property research systems. Choosing the correct system depends on the type of information a user needs.
Parcel Viewer is most useful for locating parcels through an interactive map. For additional property details, users may need to continue to related systems operated by other county offices.
The King County Property Research page explains how different tools support property searches, including Parcel Viewer, eReal Property, GIS reports, recorded documents, and other property-related resources.
When Parcel Viewer Is the Right Tool
Parcel Viewer is a useful starting point when a user needs to:
Locate a property on a map
Find a parcel using an address
Search using a parcel number
Review basic parcel information
Access related property reports
Identify connected district and development information
When Another System May Be Needed
Some property questions require a different King County system. For example, users looking for property information without map viewing may use the Assessor’s eReal Property system. Users researching recorded documents, permits, or tax information may need to work with the appropriate county office or system.
Common Parcel Viewer Mistakes
Searching Without Enough Information
Users may have difficulty locating a property if an address is entered incorrectly or if a parcel number is incomplete. Checking the information before searching can help produce better results.
Confusing Reports and Departments
Parcel Viewer connects to reports managed by different King County offices. The map application, assessment reports, and district reports serve different purposes. Selecting the correct report helps users find the information they need.
Treating Map Lines as Legal Boundaries
Parcel Viewer map boundaries are approximate. Users should not rely on the map display as a legal property survey or official boundary determination.

Parcel Viewer FAQs
How can I find a parcel when I only know the property address?
You can search for a parcel by entering an address in King County Parcel Viewer. After locating the property, select the parcel on the map to view available parcel details and access related reports. If the address search does not provide the information you need, checking the parcel directly on the map may help identify the correct property.
What reports can I access after selecting a parcel?
After selecting a parcel, Parcel Viewer provides links to related government property reports. Users can open the King County Assessor’s eReal Property report for additional property information and access the Districts and Development Conditions report for related electoral, planning, and administrative district information. These connected reports help users continue their property research through the appropriate county systems.
Why can’t I use Parcel Viewer map lines as official property boundaries?
Parcel Viewer displays lot lines for informational purposes only. The application states that lot lines are approximate and are not for legal use. If you need official property definitions, ownership documents, or recorded information, you may need to use other county records and services listed through King County property research resources.
How do I search for a parcel using a parcel number?
Users who have a parcel number can enter it into Parcel Viewer to locate the related property. Searching by parcel number can be useful when an address is unavailable or when researching a specific property record. Once the parcel is selected, the application provides access to available parcel information and linked reports.
What should I do if I need more property information than Parcel Viewer provides?
Parcel Viewer is connected with other King County property systems that provide different types of information. For property details without map viewing, users can use the Department of Assessments’ eReal Property resources. For broader geographic information, mapping layers, and additional spatial data, users can also explore King County iMap.
