An accessory dwelling is a small, secondary housing unit located
on a legal lot with an established single-family residence. Accessory
dwellings are typically the size of a studio apartment. The additional
unit can be a detached cottage, a unit attached to a garage, or in
a portion of an existing house. Accessory dwellings provide cost-effective
and independent living spaces for family members, such as in-laws,
retired parents, etc. Accessory dwellings can also provide semi-independent
living spaces for physically or mentally disabled family members requiring
partial supervision or assistance with activities of daily living.
Accessory dwellings may be rented long term as a permitted use. Accessory
dwellings may be rented as part of a permitted homestay lodging use
so long as the main structure of the property is owner-occupied. The
housing density standard of residential zones does not apply to accessory
dwellings, due to the small size and low occupancy level of the use.
The following standards are intended to control the size and number
of accessory dwellings on individual lots, so as to promote compatibility
with adjacent land uses. Accessory structures shall comply with the
following standards:
A. Oregon
Structural Specialty Code. The structure shall comply with the Oregon
Structural Specialty Code.
B. Accessory Structure Standards. The structure shall comply with the accessory structure standards of Section
16.180.010.
C. Rental
Unit. Accessory dwellings may be rented long-term as a permitted use.
Accessory dwellings may be rented as part of a permitted homestay
lodging use so long as the main structure of the property is owner-occupied.
Accessory dwellings shall not be used as servants' quarters or as
lodging (temporary or permanent) for housekeepers, gardeners, etc.
Use of an accessory dwelling for purposes other than what is expressly
permitted in this section is strictly prohibited and shall be subject
to the enforcement and penalty provisions of Chapter16.16.
D. One
Unit. A maximum of one accessory dwelling unit is allowed per lot.
E. Floor
Area. The maximum floor area of the accessory dwelling shall not exceed
600 square feet.
F. Building
Height. The building height of a detached accessory dwelling (i.e.,
separate cottage) shall not exceed the height of the primary residence,
or 16 feet measured to the apex of the roof, whichever is less.
G. Buffering.
A minimum six-foot hedge may be required to buffer a detached dwelling
from dwellings on adjacent lots, when buffering is necessary for the
privacy and enjoyment of yard areas by either the occupants or adjacent
residents.
H. Off-Street
Parking. No additional off-street parking is required if the lot already
contains at least two off-street parking spaces.
