City of Portland Planning and Zoning Code has information on what you can and cannot do on property. Planning & Zoning and Land Use Review make sure projects align with Title 33 Planning and Zoning Code.
“Zoning,” regulations are a set of rules about development that are adopted by the City of Portland’s City Council with input from neighbors, interested groups, and many other citizens. The Zoning regulations for Portland are contained in City Title 33, also called the, “Zoning Code.” In addition, another City Code (Title 11: Trees) contains rules that control tree preservation and planting requirements on private property, which can sometimes have a large impact on the development of property.
Those two City codes control what kinds of activities and development can occur on most property. The Land Use Services group in the City of Portland Bureau of Development Services (BDS) makes sure development projects comply with City Title 33 Planning and Zoning and City Title 11 (Trees). Land Use Services does this by reviewing development proposals against these codes in building permit approval processes and in processes called, “Land Use Reviews.”
Planning and zoning: base zones, overlay zones and plan districts
You can find the zoning of a property on Portland Maps under Permits and Zoning - Zoning and Districts.
Zoning regulations affect all new construction, as well as most changes to development that already exists. Zoning rules also apply to property line changes and most site activity including some tree cutting and landscaping.
All properties in the City of Portland have a “base zone”. A base zone is a designation that explains what types of uses and activities can occur on a property. Base zones also explain the rules for how big development can be, where it can be located on properties, and many other things. For example, properties with a base zone designation that starts with the letter, “R” can be used mainly for residential uses with some exceptions. Commercial uses (businesses) are mainly located in base zones that start with the letter, “C,” or sometimes, “E or I.” Find more information on the Base Zones web page.
Some properties may also have additional standards you must follow:
If the rules for development in all the levels of zoning above are followed, most development projects only need a permit issued by BDS before construction can begin. However, some sites and projects will need a Land Use Review. A Land Use Review is a detailed evaluation of requirements that are called, “Approval Criteria.”
Types of land use reviews
There are 6 types of land use reviews: Type I, Ix, II, IIx, III and IV.
Type I, Ix, II, and IIx reviews are made by Bureau of Development Services staff, who evaluate the proposal against the Approval Criteria. Type III and IV reviews involve a public hearing before the decision is made. In these reviews, Development Services staff evaluate the proposal against approval criteria and make recommendation to decision-makers in a public hearing where neighbors and interested parties are allowed to attend and comment.

The City administers City zoning to many unincorporated properties through an agreement between the two governments. However, there are some areas, like Sauvie Island, where the City does not apply our Zoning requirements. To find out what Zoning requirements apply, you can contact Multnomah County.
