(A) In addition to applicable provisions contained elsewhere in this
code, the development standards listed in this section apply to all
development in residential districts. In cases of conflicts, standards
specifically applicable in the residential land use district apply.
In cases of conflicts in this section between the general standards
and the area-specific standards, the area-specific standards apply.
Lot area and lot dimension standards for residential uses are
listed in Table 3.2.215. For other residential uses listed in Table
3.2.210, the lot area and dimensions are subject to the type of residential
structure being occupied. Lot development must be in conformance with
SDC 3.2.235, Density.
The following Table 3.2.215 sets forth residential land use
district development standards, subject to SDC 4.7.300—4.7.400.
Lots created by a middle housing land division are not subject to
the minimum and maximum lot sizes specified in this section, except
as applicable to the parent lot or parcel.

Where a minimum lot size listed in this table conflicts with
the maximum net density, by resulting in development that exceeds
the applicable maximum net density, the maximum net density standard
will prevail. This may result in an increase in the minimum lot size
provided in this table. Where no minimum lot size is listed, the minimum
lot size is determined solely based on the applicable maximum net
density.
|
Minimum lot sizes listed in this table for middle housing types
apply to the parent lot and not to any lots resulting from a middle
housing land division approved under SDC 5.12.200.
|
Density standards and minimum lot sizes within the Hillside
Overlay District are provided in SDC 3.3.520.

(A) Lot Coverage and Impervious Surface may not exceed the standards
listed in SDC 3.2.225. Stormwater treatment facilities required under
SDC 4.3.110 or other development standards may result in less impervious
surface area than these maximums.
(B) The following Lot Coverage and Impervious Surface standards apply
to all development in Residential Districts. However, Cottage Cluster
Housing is not subject to this standard.
(1) On lots or parcels with more than average 15 percent slope or above
670 feet in elevation, as determined in SDC 3.3.500, the impervious
surface area must not exceed 35 percent.
(2) On lots or parcels of less than 4,500 square feet in size, the impervious
surface area must not exceed 60 percent of the lot or parcel area.
(3) On lots or parcels of 4,500 square feet or larger in size, the lot
coverage must not exceed 45 percent of the lot or parcel area.

(6443; Ord.
No. 6482, 7/1/2024)
(A) The following net density standards apply to all new development in the R-1, R-2, and R-3 districts, except as specified in subsection
(B) of this section. The net density standards shown in Table 3.2.215 are intended to ensure efficient use of buildable lands and provide for a range of needed housing, in conformance with the Springfield Comprehensive Plan. Where the density standards apply, the net density must be within the density range for the respective district, except that density fractions 0.5 units per net acre or greater will be rounded up to the next whole number, and less than 0.5 unit per net acre will be rounded down to the preceding whole number.
The density standards may be averaged over more than 1 development
phase (i.e., as in a subdivision or within the area subject to an
adopted Master Plan). Within the Hillside Development Overlay District,
the net density standards may be met through a density transfer bonus
as provided in SDC 3.3.520(D).
(B) The net density requirements specified in Table 3.2.215 do not apply
as follows:
(1) Residential care homes/facilities.
(2) Accessory dwelling units (ADUs).
(4) Nonresidential uses, including neighborhood commercial uses, public
and institutional uses, and miscellaneous uses that do not include
a dwelling unit.
(5) Buildings that are listed in the Inventory of Historic Sites within
the Springfield Area Comprehensive Plan Exhibit “A” or
buildings designated on the Historic National Landmarks Register.
(6) Residential infill, as defined in SDC 6.1.100, is exempt from minimum
density standards, except within the HD Overlay District as provided
in SDC 3.3.505 to 3.3.540.
(7) Partitions on properties that are large enough to be divided into
5 or more lots are exempt from minimum density standards as long as
the size of the resulting parcels and siting of dwellings allow future
development on these parcels at minimum densities.
(8)
Income-qualified housing allowed pursuant to SDC 4.7.405 that
complies with SDC 4.7.405(H).
(C) Net density is defined in SDC 6.1.100 as the number of dwelling units
for each acre of land in residential use, excluding: dedicated streets;
dedicated parks; dedicated sidewalks; and other public facilities.
For the purposes of calculating residential net density, 6 single
room occupancy (SRO) units equal 1 dwelling unit. Fractional dwellings
will be rounded to the next higher number, e.g., 7 SRO rooms equal
2 dwellings. In the R-2 and R-3 districts, the number of SRO units
must be consistent with the R-2 and R-3 density standards.
(D) For the purpose of calculating residential net density:
(1) Where a property is within multiple zoning districts, the minimum
and maximum number of units is calculated based on the acreage in
each residential district that is subject to the density standard
as specified above multiplied by the applicable minimum and maximum
density standards. Areas with nonresidential districts are excluded
from the density calculation.
(2) Except as provided in subsection
(D)(3) of this section, the following areas are subtracted from the gross area of the property:
(a) Area not in residential use as provided in subsection
(D)(4) of this section;
(b) Area for dedicated streets;
(c) Area for dedicated sidewalks;
(d) Area for dedicated parks;
(e) Area for other public facilities.
After subtracting these areas from the gross area, then the
remaining area is the net area used to calculate the net density.
|
(3) The following areas are not subtracted from the gross area to calculate
net density:
(a) Area within a public easement less than 10 feet in width;
(b) Area within a private street;
(c) Area within a private park; and
(d) Area for other private facilities.
(4) Residential use. Any area not in residential use is subtracted from
the gross area. The term “residential use” is considered
to mean “of, relating to, or connected with a residence or residences.”
Examples of residential use include the following: off street parking
and vehicle circulation areas, maintenance or storage areas, and residential
leasing offices, if these uses are related to or connected with a
residence or residences.
Examples of uses that would not be considered to be in residential
use include the following: any commercial uses, accessory uses that
are not related to or connected with a residence or residences, and
unbuildable areas as described below.
(a) Unbuildable. This category includes land that is undevelopable. It
includes tax lots or areas within tax lots with 1 or more of the following
attributes:
(i)
Slopes greater than 25 percent as calculated in SDC 3.3.520(A);
(ii)
Within the floodway, as designated by the FP Overlay District;
(iii)
In areas with severe landslide potential as shown on an adopted
City of Springfield inventory or map;
(iv)
Within locally significant wetlands and locally significant
riparian areas and their setbacks as specified in SDC 4.3.117;
(v)
Within the riparian area boundary of a Water Quality Limited
Watercourse as specified in SDC 4.3.115;
(vi)
Within the easement area of a 230 kV or greater transmission
line;
(vii)
Small irregularly shaped lots; and
(viii) Publicly-owned land as described in (D)(5),
(6), (7), and (8) below.
(5) Streets. Any street or roadway dedicated as public right-of-way is
subtracted from the gross area to calculate net density. The area
does not take into account to what degree the street or roadway area
is improved. This does not include private streets or driveways. The
area for any private street would remain in the net area considered
to be in residential use.
(6) Sidewalks. Any sidewalk dedicated as public right-of-way is subtracted
from the gross area to calculate net density. A public sidewalk located
in an easement is not subtracted from the gross area. Private sidewalks
(e.g. for multifamily housing developments, etc.) are not subtracted
from the gross area.
(7) Parks. Any public park area including a publicly-owned regional park,
community park, neighborhood park, or linear park is subtracted from
the gross area to calculate the net density. Any private park, or
private open space, if not dedicated would remain in the net area.
(8) Other Public Facilities. Any area for a public facility dedicated
to the City of Springfield or other public agency is subtracted from
the gross area to calculate net density. This includes storm water
tracts dedicated to the City; however, it does not include private
storm water facilities.
Additionally, any area, including easement areas, for a public
facility that is adopted into the Eugene-Springfield Metropolitan
Area Public Facilities and Services Plan (PFSP) is subtracted from
the gross area. Any other public utility easement (PUE) that contains
public utilities that are not adopted into the PFSP are not subtracted
from the gross area (except as provided above under unbuildable land
for 230 kV transmission lines).
“Public facility projects” adopted in the PFSP include:
(a) Water. Source, reservoirs, pump stations, and primary distribution
systems. Primary distribution systems are transmission lines 12 inches
or larger for Springfield Utility Board (SUB) and 24 inches or larger
for Eugene Water and Electric Board (EWEB).
(b) Wastewater. Pump stations and wastewater lines 24 inches or larger.
(c) Stormwater. Drainage/channel improvements and/or piping systems 36
inches or larger; stormwater detention and/or treatment facilities;
outfalls; water quality projects; and waterways and open systems.
(d) Specific projects adopted as part of the Metro Plan are described
in the project lists and their general location is identified in the
planned facilities maps in Chapter II of the Eugene-Springfield Metropolitan
Public Facilities and Services Plan (Public Facilities and Services
Plan).
(6443; Ord.
No. 6482, 7/1/2024)
New triplexes and fourplexes, including those created by adding
building square footage on a site occupied by an existing dwelling,
must comply with the standards listed below. These standards do not
apply to creation of a triplex or fourplex through conversion of a
detached single-unit dwelling.
(A) Entry Orientation. At least 1 main entrance for each triplex or fourplex structure must meet the standards in subsections

(2) The combined width of all garages and outdoor on-site parking and
maneuvering areas does not exceed a total of 50 percent of the street
frontage.
(D) Driveway Approach. Driveway approaches must comply with the applicable
standards in SDC 4.2.120.
(E) Conversions to Triplex and Fourplex. Internal conversion of an existing
detached single unit structure or duplex to a triplex or fourplex
is allowed provided that the conversion does not increase nonconformance
with applicable clear and objective standards, unless increasing nonconformance
is otherwise permitted according to SDC 5.8.125.
(6443; Ord.
6466, 11/20/2023)
(A) Purpose and Title. Cottage Cluster Housing is a type of flexible
site development or subdivision that allows 4 or more small-scale
dwelling units, either attached or detached, grouped together around
shared open space.
(B) Density and Lot Size. The net density and minimum lot size must be
as provided in Table 3.2.215. There are no minimum dimensions for
individual cottage lots if divided as specified in SDC 5.12.100 or
5.12.200.
(C) Number of Dwelling Units.
(1) A Cottage Cluster development must include a minimum of 4 dwelling
units.
(D) Dwelling Unit Size.
(1) The maximum building footprint size for each dwelling unit is 900
square feet. For each dwelling unit, 200 square feet for an attached
garage or carport is exempt from the 900 square foot maximum.
(2) Detached garages, carports, or other accessory structures are exempt
from the 900 square foot maximum footprint.
(E) Accessory Structures. Accessory structures must not exceed 400 square
feet in floor area.
(F) Setbacks. The following perimeter setbacks apply to the perimeter
