Commercial Zones

The Neighborhood Commercial 1 (CN1) zone is intended for small sites in or near dense residential neighborhoods. The zone encourages the provision of small scale retail and service uses for nearby residential areas. Some uses which are not retail or service in nature are also allowed so a variety of uses may locate in existing buildings. Uses are restricted in size to promote a local orientation and to limit adverse impacts on nearby residential areas. Development is intended to be pedestrian-oriented and compatible with the scale of surrounding residential areas. Parking areas are restricted, since their appearance is generally out of character with the surrounding residential development and the desired orientation of the uses.
 
The Neighborhood Commercial 2 (CN2) zone is intended for small commercial sites and areas in or near less dense or developing residential neighborhoods. The emphasis of the zone is on uses which will provide services for the nearby residential areas, and on other uses which are small scale and have little impact. Uses are limited in intensity to promote their local orientation and to limit adverse impacts on nearby residential areas. Development is expected to be predominantly auto accommodating, except where the site is adjacent to a transit street or in a Pedestrian District. The development standards reflect that the site will generally be surrounded by more spread out residential development.
 
The Office Commercial 1 (CO1) zone is used on small sites in or near residential areas or between residential and commercial areas. The zone is intended to be a low intensity office zone that allows for small scale offices in or adjacent to residential neighborhoods. The allowed uses are intended to serve nearby neighborhoods and/or have few detrimental impacts on the neighborhood. Development is intended to be of a scale and character similar to nearby residential development to promote compatibility with the surrounding area. Development should be oriented to pedestrians along transit streets and in Pedestrian Districts.
 
The Office Commercial 2 (CO2) zone is a low and medium intensity office zone generally located on Major City Traffic Streets as designated by the Transportation Element of the Comprehensive Plan. Uses are limited to those in the Office category and may have a local or regional emphasis. The zone is intended to prevent the appearance of strip commercial development by allowing office uses but not other commercial uses. Commercial uses are also restricted to limit detrimental impacts on nearby residential areas. Development is expected to be somewhat auto-accommodating. Where the site is adjacent to a transit street or in a Pedestrian District, development should be oriented to pedestrians. The development standards allow for more intense development than in the CO1 zone, but not so intense as the CG zone.
 
The Mixed Commercial/Residential (CM) zone promotes development that combines commercial and housing uses on a single site. This zone allows increased development on busier streets without fostering a strip commercial appearance. This development type will support transit use, provide a buffer between busy streets and residential neighborhoods, and provide new housing opportunities in the City. The emphasis of the nonresidential uses is primarily on locally oriented retail, service, and office uses. Other uses are allowed to provide a variety of uses that may locate in existing buildings. Development is intended to consist primarily of businesses on the ground floor with housing on upper stories. Development is intended to be pedestrian-oriented with buildings close to and oriented to the sidewalk, especially at corners.
 
The Storefront Commercial (CS) zone is intended to preserve and enhance older commercial areas that have a storefront character. The zone intends that new development in these areas will be compatible with this desired character. The zone allows a full range of retail, service and business uses with a local and regional market area. Industrial uses are allowed but are limited in size to avoid adverse effects different in kind or amount than commercial uses and to ensure that they do not dominate the character of the commercial area. The desired character includes areas which are predominantly built-up, with buildings close to and oriented towards the sidewalk especially at corners. Development is intended to be pedestrian-oriented and buildings with a storefront character are encouraged.
 
The General Commercial (CG) zone is intended to allow auto-accommodating commercial development in areas already predominantly built in this manner and in most newer commercial areas. The zone allows a full range of retail and service businesses with a local or regional market. Industrial uses are allowed but are limited in size to avoid adverse effects different in kind or amount than commercial uses and to ensure that they do not dominate the character of the commercial area. Development is expected to be generally auto-accommodating, except where the site is adjacent to a transit street or in a Pedestrian District. The zone’s development standards promote attractive development, an open and pleasant street appearance, and compatibility with adjacent residential areas. Development is intended to be aesthetically pleasing for motorists, transit users, pedestrians, and the businesses themselves.
 
The Central Commercial (CX) zone is intended to provide for commercial development within Portland’s most urban and intense areas. A broad range of uses is allowed to reflect Portland’s role as a commercial, cultural and governmental center. Development is intended to be very intense with high building coverage, large buildings, and buildings placed close together. Development is intended to be pedestrian-oriented with a strong emphasis on a safe and attractive streetscape.
