PropertyQuest has been developed by the District of Columbia Office of Planning as an easy way to view a wide range of site-related information, especially information on historic resources.

• This site draws information from databases assembled and provided by other agencies. Information provided is for planning purposes only. Please consult the source agencies listed in the “About the Data” tab for definitive answers.
   
• This site uses Adobe’s Flex technology to display information and ESRI’s ArcGIS Server to supply spatial data for mapping and analysis. When you enter an address, it looks the address up in DC’s Master Address Repository and finds the specific location. It then searches in that location on the map for the matching lot, and searches again for historic resources that might be present on that lot.
   
• The current version relies on Adobe Flash.  A mobile-friendly edition is coming soon.
