Historic Reviews are required for certain proposals that affect Historic Landmarks, Conservation Landmarks or Historic Resource Inventory Listings and for proposals in Historic and Conservation Districts. To find out if your site is located within a Historic or Conservation District, review maps in the related Historic Districts and Conservation Districts webpage.
Six types of Historic Reviews
Historic Resource Review
Historic Resource Review allows for review of alterations to existing historic resources and review of new development within designated districts. For some proposals, the applicant may choose to meet the objective standards of Chapter 33.218, Community Design Standards instead of going through the historic design 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.
- Design Modifications may be requested as part of the design review for standards that are not met. See Portland Zoning Code Sections 33.445.050 and 33.846.070.
- Adjustments may be requested concurrent with the design review for use-related standards that are no met (such as floor area ratios, intensity of use, size of the use, number of uses, or concentration of uses).
Historic Designation Review
Historic Designation Review allows for the designation of a historic resource as a Historic Landmark, Conservation Landmark, Historic District, or Conservation District.
Historic Designation Removal Review
Historic Designation Removal Review allows for the designation removal from a Historic Landmark, Conservation Landmark, Historic District, or Conservation District.

Demolition Review is required to demolish some Historic Landmarks, Conservation Landmarks, historic resources in a Historic District, historic resources in a Conservation District, and resources listed in the Historic Resource Inventory.
Demolition Delay Review
