Proposed Revisions to City of Portland’s Title 24.85 "Seismic Design Requirements for Existing Buildings"

City of Portland, Bureau of Development Services

The City of Portland is proposing to revise Title 24.85 Seismic Design Requirements for Existing Buildings. In December 2014, Bureau of Development Services, City of Portland, requested comments and feedback on the proposed changes from interested parties. The comments submitted in response to this request were considered by the City’s Structural Advisory Board in February 2015.

The recommendations of the Structural Advisory Board to the proposed changes and the comments along with the revised proposal may be viewed by clicking on the links provided below.

The Bureau of Development Services is interested in getting your feedback on the revised proposed changes. Since comments to original proposal were due and submitted by December 31, 2014, we request that new comments be limited to recommendations of the Structural Advisory Board and resolution of previous comments submitted. Please email your comments to by March 27, 2015.
