Historic preservation incentives increase the potential for historic resources to be used, rehabilitated, and preserved. In Portland, a variety of these incentives are provided by local, state, federal, and non-profit entities. Many of them prioritize rehabilitation of designated historic resources in accordance with local regulations and/or federal historic preservation standards.
Incentives not specifically intended for historic preservation activities, including programs offered by Prosper Portland and grants provided by arts and culture foundations, are not described on this page. Single-family homes – regardless of historic status – are ineligible for many of the incentives described on this page.
Tax Incentives
Federal Rehabilitation Tax Credit
A 20% federal income tax credit is available for the rehabilitation of income-producing historic resources that have been listed in the National Register of Historic Places. To be eligible for the Federal Rehabilitation Tax Credit, rehabilitation expenses must be “substantial” and alterations, both interior and exterior, must meet the Secretary of Interior’s Standards for Rehabilitation. Owner-occupied single-family residences are not eligible. Questions regarding program requirements and eligibility should be directed to the Oregon State Historic Preservation Office.
Oregon Special Assessment of Historic Property Program
Since 1975, Oregon has provided limited property tax relief for historic resources that have been listed in the National Register of Historic Places. To be eligible for a 10-year Special Assessment of Historic Property, historic resource owners must agree to a preservation plan for the property and commit to minimum rehabilitation expenditures. In some cases, seismic, energy, or accessibility upgrades are required. Unlike many historic preservation incentives, owner-occupied single-family residences are eligible for this incentive. Questions regarding program requirements and eligibility should be directed to the Oregon State Historic Preservation Office.
Zoning Incentives
Adaptive Reuse Flexibility
The Portland Zoning Code provides adaptive reuse flexibility to certain historic resources, allowing continued and adaptive use of Historic and Conservation Landmarks and certain properties in Historic and Conservation Districts. The incentives allow for additional residential density in single-dwelling zones, limited commercial uses in single- and multi-dwelling zones, and major adaptive reuse in zones where new uses aren’t generally allowed. The adaptive reuse incentives reside in Portland Zoning Code section 33.445.400.
Exception to Parking Requirements
To allow for the use and ongoing preservation of historic resources, the Portland Zoning Code does not require parking spaces on sites that contain a Historic, Conservation, or National Register Landmark and sites located within a Historic, Conservation, or National Register District. The historic resource parking exception resides in Portland Zoning Code section 33.266.110.
Transfer of Development Rights
The Portland Zoning Code allows for the transfer of development rights from some historic resources in certain zones to support the ongoing preservation of historic resources, allowing otherwise unused development capacity to be built on developable sites. Provisions for Floor Area Ratio (FAR) transfer reduce redevelopment pressure on historic resources and allow unused FAR to be monetized to support seismic upgrades and other rehabilitation work. Historic resource FAR transfer provisions reside in the Portland Zoning Code chapters pertaining to multi-dwelling, mixed-use, and employment zones and the Central City plan district.
