ORDINANCE NO. 5960
4-2-116 ACCESSORY DWELLING UNIT RESIDENTIAL DESIGN STANDARDS:
A. PURPOSE:
Accessory Dwelling Units (ADUs) are intended to create affordable, flexible
housing opportunities that take advantage of the City's existing infrastructure
while addressing the need for increased housing choices that reflect changing
lifestyles and environmental concerns.
The purpose of this Section is to encourage development that enhances
quality of life by encouraging new residential development to produce
neighborhoods of well-designed homes and promote and facilitate ADU
construction in new and existing developed areas,while preserving neighborhood
character and ensuring minimal disruption to surrounding property owners.
This Section lists elements that are required to be included in all ADU
development in the zones stated in subsection B of this Section. Each element
includes both standards and guidelines. Standards are provided for predictability.
These standards specify a prescriptive manner in which the requirement can be
met. Guidelines for each element are provided for flexibility. These guidelines
provide direction for those who seek to meet the required element in a manner
that is different from the standards.
1. The determination as to the satisfaction of the requirement through the
use of the guidelines is to be made by the Community and Economic Development
Administrator when no other permit or approval requires Hearing Examiner
review.
8
ORDINANCE NO. 5960
2. When it has been determined that the proposed manner of meeting the
design requirement through guidelines is sufficient,that design requirement shall
be considered satisfied.
B. APPLICABILITY:

structure shall be brought to compliance prior to the issuance of ADU building
permits.
C. REQUIREMENTS:
WINDOWS AND.DOORS:Windows and front doors are an integral part of.the architectural
character of a home and when they incorporate architectural elements of the home,they

represent a significant amount of the facade of a home,they amplify the sense that the
community is oriented to people.
Guidelines:Windows and doors shall serve as an integral part of the character of the home.
Primary windows shall be proportioned vertically rather than horizontally. Vertical windows
may be combined together to create a larger window area. Front doors shall be a focal point of
the dwelling and be in scale with the home. All doors shall be of the same character as the
home and architecturally consistent with the doors on the primary structure.

character of a home. When sized adequately and used consistently,they work to create
desirable shadows that help to create visual interest especially from blank, unbroken wall
planes.
Guidelines: Eaves should be detailed and proportioned to complement the architectural style of
the home.
Standards:
Both of the following are required:
1. Eaves projecting from the roof of the entire building at least twelve
inches (12") with horizontal fascia or fascia gutter at least five

4-2-1100.E CONDITIONS ASSOCIATED WITH DEVELOPMENT STANDARDS
TABLE FOR RESIDENTIAL ZONING DESIGNATIONS
1. a. Phasing, shadow platting, or land reserves may be used to satisfy
the minimum density requirements if the applicant can demonstrate that the
current development would not preclude the provision of adequate access and
infrastructure to future development and would allow for the eventual
satisfaction of minimum density requirements through future development.
Within the Urban Center, surface parking may be considered a land reserve.
b. In the event the applicant can show that minimum density cannot
be achieved due to lot configuration, lack of access, environmental or physical
constraints, minimum density requirements may be waived.
2. Use-related provisions are not variable. Use-related provisions that are
not eligible for a variance include: building size, units per structure/lot, or
densities. Unless bonus size or density provisions are specifically authorized, the
modification of building size, units per structure, or densities requires a legislative
change in the code provisions and/or a Comprehensive Plan amendment/rezone.
3. Within designated urban separators, clustering is required; individual
lots shall not be less than ten thousand (10,000) square feet and development
shall be consistent with RMC 4-3-110, Urban Separator Overlay Regulations.
Outside of designated urban separators, clustering may be allowed in order to
meet objectives such as preserving significant natural features, providing
neighborhood open space, or facilitating the provision of sewer service. The
44 [ATTACHMENT C]
ORDINANCE NO. 5960
maximum net density shall not be exceeded; except within urban separators a
density bonus may be granted allowing the total density to achieve one dwelling
unit per gross contiguous acre. In order for the bonus to be allowed, projects must
provide native vegetation cover(either existing or new)on sixty five percent(65%)
of the gross area of all parcels in the land use action, including both the area within
and outside the open space corridor. In addition, projects shall provide at least
one of the following:
a. Enhancement of wetlands at a ratio of one-half(1/2)acre enhanced
for one acre delineated within the urban separator pursuant to RMC 4-3-
050M12b, Evaluation Criteria, and RMC 4-3-050M12c, Wetlands Chosen for
Enhancement. Enhancement proposed for a density bonus may not also be used
for a mitigation for other wetland alterations; or
b. The removal of and/or bringing into conformance with Renton
standards of legal nonconforming uses from the site; or
c. Natural surface pedestrian trails with public access. The trails can
be part of an adopted trail system or, where there is no planned trail system, of a
configuration approved by the Community and Economic Development
Administrator. In the absence of either wetlands or legal nonconforming uses on
the site, public access and trails shall be provided and approved by the Community
and Economic Development Administrator.
4. Allowed Projections into Setbacks:

reduction of the front yard and/or secondary front yard setback; and
b. The setback reduction is the minimum necessary to attain the
allowed building coverage; and
c. If a setback reduction is approved under this provision the
exceptions to setbacks pursuant to subsection D4 of this Section (Allowed
Projections into Setbacks)shall apply unless the proposed projection is closer than
five feet(5')to the property line/easement,except for eaves,which may encroach
the minimum five feet (5') setback as specified in subsection D4 of this Section.

12. Roofs of Modulated Facades: Wall plates of a modulated portion of
a building may exceed the maximum wall plate height if the roof surface does not
exceed the ridgeline of the primary roof surface.Such facade modulations shall be
no wider than ten feet (10')or twenty five percent(25%)of the building elevation,
whichever is greater.
13. If the lot abuts a single family residential zone (RC through R-14) a
fifteen foot (15') setback shall be required along the abutting side(s) of the
property.
14. For plats that create lots of a size large enough to allow future division
under current lot size minimums and allow the potential to exceed current density
49 [ATTACHMENT C]
ORDINANCE NO. 5960
maximums, covenants shall be filed as part of the final plat requiring that future
division of those lots in question must be consistent with the maximum density
requirements as measured within the plat as a whole as of the time of future
division, as well as the general lot size and dimension minimums then in effect.
15. Accessory dwelling units shall not be included in density calculations.
16. The square foot calculation shall not include porches, exterior stairs,
or garages.
17. The lot coverage of accessory dwelling units shall not be calculated
towards maximum building/lot coverage.
18. Vertical Projections from Wall Plates:
a. Roofs with a pitch equal to or greater than 4:12 may project an
additional six (6)vertical feet from the maximum wall plate height. If the height of
wall plates on a building are less than the stated maximum the roof may project
higher to account for the difference, yet the combined height of both features
shall not exceed the combined maximums (e.g., if the maximum wall plate height
of a zone is twenty-four feet (24') and the wall plates of a structure are no taller
than twenty feet (20'), the roof may project up to ten feet (10') instead of six feet
(6')). Common rooftop features, such as chimneys, may project an additional four
(4) vertical feet from a roof surface.

plate height. Deck enclosures (i.e., railings) located above the maximum wall plate
height and not stepped back shall be constructed of transparent tempered glass
or its equivalent, as determined by the Administrator.
19. Shed Roofs: Wall plates supporting a primary roof surface that has
only one sloping plane (e.g., shed roof) may exceed the stated maximum if the
average of wall plate heights is equal to or less than the maximum wall plate
height allowed.
20. An additional ten feet (10') of maximum wall plate height and an
additional story for a residential dwelling structure may be obtained through the
provision of additional amenities such as additional recreation facilities,
underground parking,and additional landscaped open space areas;as determined
through the site development plan review process and depending on the
compatibility of the proposed buildings with adjacent or abutting existing
residential development.The maximum wall plate height of a residential structure
shall not exceed forty two feet (42').
21. The Community and Economic Development Administrator or
designee may modify this provision through the site development plan review
process where it is determined that specific portions of the required on-site
perimeter landscaping strip may be developed and maintained as a usable public
open space with an opening directly to a public entrance.
51 [ATTACHMENT C]
ORDINANCE NO. 5960

31. In order to meet the variation requirements of RMC 4-2-115, lot
dimensions and setbacks are allowed to be decreased and/or increased; provided,
that when averaged the applicable lot standards of the zone are met. The
minimum front and rear yard setback reduction shall be limited to two and one-
half feet (2.5') or ten percent (10%), whichever is greater. The minimum lot width
and lot area reduction shall be limited to ten percent (10%) of the lot width and
lot area of the zone. The variation requirements of RMC 4-2-115 do not require
52 [ATTACHMENT C]
ORDINANCE NO. 5960
variations to the lot depth requirements;therefore the averaging provision is not
applicable to the minimum lot depth requirements.
32. Reserved.
