Master Property Record, or MPROP as it is commonly called, is a computerized inventory of all properties in the city. It contains more than 90 elements of data describing each of the approximately 160,000 properties in the city. The file was created in 1975 to provide current and accurate property information with enough flexibility to be accessed in a variety of ways. Since it was implemented and made available, the data has become invaluable and is currently used by nearly every city department. This same data is now being broadly distributed in a format that is compatible with commonly available computer equipment and operating systems.

MPROP is available in ASCII format. MPROP data currency is based on file date.   This file is approximately 75 MB and may take some time to download depending on the speed of your connection.

MPROP is available in  XML format.  This file is compressed (zipped).   The file is approximately 18 MB compressed.  After saving the zipped file to your hard drive, and extracting it, the resulting XML file will be approximately 400 MB containing around 160,000 records.  Be patient, the importing of this data into Microsoft Access (or any other database) will take some time.

Documentation for MPROP is available in word (.doc) format.
