Historic Reviews are required for certain proposals that affect Historic Landmarks or Conservation Landmarks and for proposals in Historic and Conservation Districts. To find out if your site is a Landmark or located within a Historic or Conservation District, review maps on the related Historic and Conservation Districts web page or search for your property on PortlandMaps.com.
Six types of Historic Reviews
Historic Resource Review
Historic Resource Review allows for review of alterations to, and new development within the boundary of, Historic Landmarks, Conservation Landmarks, and resources within Historic and Conservation Districts.
It also considers relocation of Historic and Conservation Landmarks and contributing resources within Historic and Conservation Districts.
For some proposals affecting Conservation Landmarks and within Conservation Districts, the applicant may choose to meet the objective standards of Chapter 33.218, Community Design Standards instead of going through the Historic Resource Review process set out in Chapter 33.846. Additionally:
- As part of the Historic Resource Review application, a Modification or Adjustment review may be required if the proposal does not meet certain development standards.
- Modifications may be requested as part of the Historic Resource Review for standards that are not met. See Portland Zoning Code Section 33.846.070.
- Adjustments may be requested concurrent with the Historic Resource Review for use-related standards that are not met (such as intensity of use, size of the use, number of uses, or concentration of uses). See Portland Zoning Code Section 33.805.
Historic Designation Review
Historic Designation Review allows for the designation of a historic resource as a Historic Landmark or Conservation Landmark, expansion of the boundary of a City-designated Historic or Conservation Landmark or District, or reclassification of resources within the boundary of a City-designated Historic or Conservation Landmark or District as contributing.
Designation of a Historic District or Conservation District is only allowed through a legislative procedure.
Historic Designation Removal Review
Historic Designation Removal Review allows for the designation removal from a Historic Landmark or Conservation Landmark, reduction of the boundary of a City-designated Historic or Conservation District, or reclassification of resources within a City-designated Landmark or District as noncontributing.
Removal of a City-designated Historic District or Conservation District is only allowed through a legislative procedure.
Historic Preservation Incentive Review
Historic Preservation Incentive Review increases the potential for Historic Landmarks, Conservation Landmarks, and contributing resources in Historic and Conservation Districts to be reused, rehabilitated, and preserved.
Demolition Review
Demolition Review is required to demolish Historic Landmarks, Conservation Landmarks, National Register Landmarks, contributing resources in a Historic District, contributing resources in a Conservation District, and contributing resources in a National Register-listed Historic District.
120-Day (Demolition) Delay
A 120-day (Demolition) Delay is required to demolish Significant Resources listed in the City’s Historic Resource Inventory.
