Historic Review Board Policies
Projects that meet the Historic Review Board (HRB) policies do not have to request approval from HRB and rather may obtain administrative staff approval. Where an alteration does not meet the policies, a Type III review by the HRB will be necessary.
These policies are authorized by Section 17.40.060 of the Oregon City Municipal Code and apply to designated historic structures in Oregon City, including:
- All properties in the Canemah National Register Historic District, as the District boundaries existed on February 1, 2017.
- All designated structures in the McLoughlin Conservation District
- All structures individually designated on the National Register before February 1, 2017, and local landmarks located outside of historic districts
City staff are available to help property owners determine if their projects satisfy the HRB policies. Property owners are strongly encouraged to seek advice from City staff before proceeding with changes to historic properties. Changes that do not meet the policies are subject to code enforcement action. The policies do not apply to regular maintenance or repair of existing structures.
Oregon City Preservation Program
The Historic Review Board updated the HRB Policies. These HRB Policy updates are effective as of August 7th, 2019.
These guidelines are authorized by Section 17.40 60 of the Oregon City Municipal Code. Owners of properties that do not fall under the Historic Review Process are encouraged to follow the Policies set forth by the Historic Review Board by making exterior alterations that maintain the structure's integrity and are compatible with the neighborhood.
For additional information, read HRB Policies - Effective August 7, 2019 (PDF).
The finished floor elevation of the structure shall not be raised or lowered in relation to the ground level as a result of foundation construction or repair. Any new foundation shall be covered with skirting that matches the original skirting on the structure.
Storm window frames and members shall be made of wood, baked enamel, or anodized aluminum. If wooden or enameled, the frames and members shall be painted to match the color of the existing window trim. Mill-finish aluminum storm windows are not permitted. Interior storm windows are encouraged.
New siding shall match the original siding both in material and style. A sample must be submitted for review.
Replacement of wooden gutters and downspouts is permitted. Galvanized or enameled aluminum gutters and downspouts shall be painted to match the house. All support straps shall be painted to match the house. New downspouts shall be located to avoid visual interference with the architectural features of the street façade. Plastic gutters and downspouts are not permitted. If the downspout empties onto the ground, splash blocks shall be placed at the outflow to disperse the water away from the foundation.
Structures shall be re-roofed with either wood shingles, 3-tab composition shingles, or "architectural style" composition shingles. If the roof slope is less than 4/12, rolled composition roofing may be used. Red, dark green, black, dark brown, or green and white composition material is encouraged. Slate, tile, or tar and gravel roofs may be re-roofed with like materials. The following roof materials are not permitted without Board approval: metal, fiberglass, plastic, corrugated roofing, or shake shingles. Any alteration to the overhang, soffit, or rake board requires Board approval.
- HRB Policy #8 - Exterior Alterations to Buildings in National Historic Districts / Structures in Conservation Districts / Landmark Structures
Additions shall be reviewed by the HRB. Other alterations are subject to administrative review. Alterations are permitted if they duplicate existing building materials and styles. Wood siding is encouraged if the siding is replaced. Aluminum and vinyl siding and vinyl and aluminum mill finish windows are not permitted unless the building was originally constructed of such materials and they are greater than 50% of the materials on the building. Wood sash doors are encouraged. Roof alterations shall conform to HRB Policy Number 5.
Wood storm and screen doors are preferred. If aluminum or other metal storm/screen doors are used, they shall be prefinished or painted a color to match the door or trim. Unless replicating a historic storm/screen door, screen doors shall not obscure the primary door design, and shall not include decorative details or simulated muntins (grids).
