The Bureau of Planning and Sustainability is advancing a zoning code project that will make changes to how the City of Portland identifies, designates and protects historic resources. The Historic Resources Code Project follows a 2016 Oregon State Supreme Court decision and recently-adopted changes to state administrative rules, both of which provide opportunities for improving Portland’s historic resource protection programs. During this moment of citywide growth and change, the project seeks to better align the city’s historic preservation programs with other community goals.

The Historic Resources Code Project launched in September 2017. Following review of state and national best practices and a series of public roundtable sessions, a Discussion Draft of the proposed zoning code changes was released in January 2019.
