URM Database

The Bureau of Development Services Unreinforced Masonry (URM) Building database is a list containing information on buildings located in the City of Portland which are believed to be of unreinforced masonry construction. The URM Database was originally compiled in the 1990’s and was recently updated. The update included verifying the database accuracy using tools such as Google maps, reflecting the categorization of structures due to demolitions and permitted seismic upgrades and performing site visits. While every effort was made to confirm the information, accuracy of the database cannot be guaranteed due to a number of factors. Some buildings may have more than one address or have an address different than what is shown in the database and not all permitted building records could be located. Some of the buildings may not be of URM construction. Some of the buildings may have been improved to better resist seismic loads. If this is known, it is indicated in the database.

Important Disclaimers
The City of Portland makes no representations, expressed or implied as to the accuracy of this database. There are no assurances as to whether the information presented is correct or comprehensive.

The presence of a building in this database is not a predictor of its performance in a seismic event. Many factors contribute to building damage during seismic events. Some, but not all, causes include: the size and location of the seismic event; local soils upon which the building is founded; the shape of the building; the design of the building; the construction quality; and if the building has been structurally modified. The services of a licensed professional engineer are needed to determine the capacity of a building to resist seismic loads.

Any publication or distribution that is made of this information or any conclusions drawn from this information should be made with the limitations noted above in mind. Any publication or distribution of this information would be solely at your own risk.
