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
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
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.
