under the Growth Management Act (GMA) must adopt development regulations allowing
co -living as a permitted use on any lot located within an urban growth area that allows at
least six multifamily residential units, including on a lot zoned for mixed -use development;
and
WHEREAS, requirements for co -living take effect December 31, 2025. By this
date, subject cities and counties must adopt or amend co -living housing standards,

by this date, the requirements of RCW 36.70A.535 will "supersede, preempt, and
invalidate any conflicting local development regulations"; and
WHEREAS, per RCW 36.70A.535(2), cities may not require co -living housing
proposals to contain room dimensional standards, require a mix of unit sizes or number
of bedrooms, or require other uses within project; and
WHEREAS, per RCW 36.70A.535(3), cities may not require co -living housing to
provide off-street parking when the project site is within one-half mile walking distance of
a major transit stop or provide more than 0.25 off-street parking spaces per sleeping unit;
and
WHEREAS, per RCW 36.70A.535 cities may not require, through development
regulations any standards for co -living housing that are more restrictive than those that
are required for other types of multifamily residential uses in the same zone. A city or
county may only require a review, notice, or public meeting for co -living housing that is
required for other types of residential uses in the same location, unless otherwise required
by state law including, but not limited to, shoreline regulations under Chapter 90.58 RCW.
Cities may not exclude co -living housing from participating in affordable housing incentive
programs under RCW 36.70A.540, may not treat a sleeping unit in co -living housing as
more than one -quarter of a dwelling unit for purposes of calculating dwelling unit density,
and may not treat a sleeping unit in co -living housing as more than one-half of a dwelling
unit for purposes of calculating fees for sewer connections; and

18.02.067 Units allowed per lot.
E. Lot Area per Unit Above Base Allowance. Additional units beyond what is allowed under ACC
18.25.040(A) are allowed based on lot area above the minimum lot size threshold. One
additional unit is allowed above the base for each interval of the value shown in ACC
18.07.030(D)(3) up to the maximum number of units per lot (ACC 18.07.030(D)(4)), except for
courtyard housing. For example: a lot with an area of 5,650 square feet in the R-2 zone may
have one additional unit above the base of four because it is 1,250 square feet larger than the
minimum lot size.
F. Maximum Units per Lot.
1. Except for courtyard housing, the total number of units shall not exceed the value listed
in ACC 18.07.030(D)(3).
2. The maximum number of units for courtyard housing is two times the number of units
listed in ACC 18.07.030(D)(4).
3 For the purpose of calculating density for co-livinghousing, ousing one sleeping unit shall
equate to 0.25 dwelling units For example a co -living housing development with 16
sleeping units would equate to 4 dwelling units.

18.07.020 Uses.
18.07.030 Development standards.
18.07.010 Intent.
A. General. This section describes the intent for each of the city's residential zones. These
intent statements may be used to guide the interpretation of the regulations associated with
each zone.
B. RC Residential Conservancy Zone.
1. RC residential conservancy zone is intended primarily to provide for low -intensity
single-family residential uses with characteristics of an agricultural environment; provided,
that the agricultural uses are secondary to the single-family uses. These areas allow for a
lifestyle similar to that of rural areas that includes allowance of farm animals and streets
without sidewalks. This zone is intended to protect areas with significant environmental
constraints or values from impacts typically associated with urban levels of development
while allowing low -intensity development designed to minimize impacts on the natural
environmental features designated for conservation.
2. Public improvements required within the RC zone will be less than is normally required
for the higher intensity residential zones within the city and are not subject to the city's
complete streets policies.
3. This zone shall only be applied in areas designated as residential conservancy on the
comprehensive plan.
C. R-1 Residential Zone.
The Auburn City Code is current through Ordinance 6977, passed June 16, 2025.
Chapter 18.07 ACC, Residential Zones
Page 2 of 9
1. The intent of the R-1 residential zone is to provide areas for estate -type residential
development on large lots in areas that are intended to create an open space separation
between existing urban areas that are unique from each other and where limited public
utilities and transportation infrastructure are present.
Appropriate development standards required of other urban areas shall be required to
serve this zone.
2. R-1 implements the Neighborhood Residential One comprehensive plan land use
designation.
D. R-2 Residential Low Zone.
1. The R-2 residential low zone is intended for lower -intensity residential development
consisting of single -unit detached houses, townhouse, duplex, triplex, fourplex, two-story
stacked flats, courtyard apartments, cottage housing on lot sizes typical of suburban and
urban development. This residential zone allows flexibility in the types and densities of
housing permitted while at the same time maintaining a desirable family living
environment by establishing minimum usable open spaces, maximum impervious
coverage, and maximum units per lot area with the character and scale of traditional
single -unit detached neighborhoods.
2. A related consideration of this zone is to provide a transition between low -intensity
residential development areas and higher- and lower -intensity designations. Small-scale,
community -based commercial development that provides services to the local
neighborhood will be considered through the administrative use permit process.
3. R-2 implements the Neighborhood Residential Two comprehensive plan land use
designation.
E. R-3 Residential Moderate Zone.
1. The intent of the R-3 residential moderate zone is to allow all residential and
commercial types and uses provided in the R-2 residential zone, while allowing additional
intensity through allowing stacked flats up to three stories, fiveplexes, a-n4 sixplexes, and
co -living housing. Single -unit detached houses are not permitted in the R-3 zone.
Apartment buildings and mixed -use development consisting of no more than 20 units and
three stories per lot is permitted. Supportive housing and residential care developments
The Auburn City Code is current through Ordinance 6977, passed June 16, 2025.
Chapter 18.07 ACC, Residential Zones
Page 3 of 9
are permitted in this zone to provide additional needed housing options but must still
adhere to the residential density and unit limitations established within this category.
Small-scale commercial development providing services to the area is encouraged in this
zone and implemented through the administrative use permit process.
2. R-3 implements the Neighborhood Residential Two comprehensive plan land use
designation.
F. R-4 Residential High Zone.
1. The R-4 residential high zone is intended to maximize residential density opportunities
and is further intended as a residential zone primarily of middle housing and multiple -story
apartment and mixed -use development. This zone is characterized by a more active living
environment near transit, urban services and commercial uses. The R-4 residential zone
allows for all uses allowed in the R-3 zone, plus apartment and mixed -use development of
more than 20 units and three stories per lot is permitted. Small-scale commercial
development providing services to the area is encouraged in this zone and implemented
through the administrative use permit process.
2. R-4 implements the Neighborhood Residential Three comprehensive plan land use
designation.
G. R-NM Residential Neighborhood Mixed -Use Zone.
1. The intent of the R-NM residential neighborhood mixed -use zone is to provide a flexible
approach that achieves a mix of dense residential development and light commercial uses
in either a vertical or horizontal configuration. Within this zone there will be a mix of retail,
office, middle housing. co -living housing, and multi -story residential uses, with attractive
design and accessible spaces for people to live, work, and visit. This zoning designation is
served primarily by a combination of transit, pedestrian, and/or bicycle facilities allowing
people to access amenities without needing a personal vehicle. Uses and densities allowed
within this zone will be consistent with the uses permitted in the C-1 light commercial and
the densities of the R4 residential high zone. New development and redevelopment will
incorporate a mix of residential and commercial uses. In addition, parks and open spaces
are encouraged and may be permitted through the administrative use permit process.
The Auburn City Code is current through Ordinance 6977, passed June 16, 2025.
Chapter 18.07 ACC, Residential Zones Page 4 of 9
2. Street -level development is encouraged to be retail or higher traffic local businesses or
offices, and residential is encouraged on the upper levels of buildings. This zoning district
should be walkable and bikeable to neighborhood commercial services and transit facilities
and have a high level of street activation and amenities.
H. R-F Residential Flex Zone. The R-F residential -flex zone is intended primarily to accommodate
small-scale business and professional offices, medical and dental clinics, salons and other
personal services, eating and drinking establishments, and banks and similar financial
institutions at locations where they are compatible with residential uses. Accessory retail may
be permitted if supplemental to the other uses allowed in the zone. This zone is intended for
those areas that are in transition from residential to commercial uses along corridors serving
lower density residential land uses. Conversion of residential uses to commercial uses is geared
towards encouraging adaptive reuse of existing single -unit structures that continue to appear in
accord with the single -unit residential character. New development in the R-F residential -flex
zone should not exceed two stories or footprint that is designed to maintain a character and a
scale smaller than the R-NM residential neighborhood mixed -use residential zone. (Ord. 6959 § 1
(Exh. A), 2024; Ord. 6525 § 6, 2014; Ord. 6245 § 5, 2009.)

commercial and industrial zone and the land use approval process required to establish each
use.
B. Requirements for Certain Specific Land Uses. Where the last column (Standards for Specific
Land Uses) in Table 18.23.030 includes a reference to a code section number, the referenced
section determines other requirements and standards applicable to the use regardless of
whether it is permitted outright or requires an administrative or conditional use permit.
C. Uses Affected by the Airport Overlay. Refer to Chapter 18.38 ACC to determine whether uses
are separately prohibited by that chapter or will be required to comply with additional
regulations that are associated with the airport overlay.

Page 1 of 6
18.52.020 Number of off-street parking spaces required.
Each principal use of the land, building, or structure shall provide the number of off-street
parking spaces required by this section. The following standards are not applicable in the DUC,
downtown urban center zone; refer to Chapter 18.29 ACC for specific requirements for that
zone.
A. Parking Requirements by Land Use.
1. Minimum Number of Parking Spaces. Each land use shall provide the minimum number
of off-street parking spaces required by Table 18.52.020, except where a greater number of
spaces are required through a more specific approval process such as an administrative
use permit or conditional use permit approval.
2. Uses Not Listed. Where a use is not listed in Table 18.52.020, the planning director shall
determine the number of required parking and/or loading spaces. The planning director
shall use the requirements in Table 18.52.020 as a guide in determining the number of off-
street parking spaces required based on the similarity of uses or may consider a parking
generation study.
B. Maximum Number of Parking Spaces. Except for required parking spaces for persons with
disabilities, spaces provided in park and ride lots operated by a public transit agency, spaces for
carpools, spaces for electric vehicle charging and spaces within structured parking with two or
more levels, the maximum number of parking spaces for nonresidential uses shall not exceed
125 percent of the minimum spaces required by Table 18.52.020.
C. Measurement of Floor Area. In any case where Table 18.52.020 establishes a parking
requirement based on floor area in square feet (for example: two spaces per 1,000 square feet
(sf) of floor area), the floor area shall be construed to mean gross floor area (defined in ACC
18.04.430).
D. Use With Accessory Components. A single use with accessory components shall provide
parking for the primary use, and each component. For example, a hotel with a meeting room
may be required to provide the parking spaces required by Table 18.52.020 for a hotel (i.e., the
guest rooms), and for a meeting room.
The Auburn City Code is current through Ordinance 6992, and legislation passed August 18, 2025.

E. Obstruction. Removal of required parking or loading spaces from practical use by
obstruction, erection of buildings, or other actions as to reduce the parking or loading capacity
or usefulness thereof below the minimum requirements established in this chapter is
prohibited.
F. Existing Legally Nonconforming Gravel Spaces. Up to six legally nonconforming gravel parking
spaces may be used to meet off-street parking requirement for residential development.
