10.47.015 Applicability.

The standards described in this chapter apply to the establishment of the applicable housing types, except as otherwise noted in this chapter or in any cited codes or documents. Applicability includes the following situations:

(1) New construction.

(2) The conversion of existing structure(s) to a particular housing type. When existing structure(s) are converted to housing, regardless of whether they contain housing units already, the applicant shall demonstrate compliance with the standards that apply to the proposed housing type(s). (Ord. 2020-35 § 3 (Exh. A))

10.47.020 Residential structures.

All residential structures where allowed by Chapter 10.10 WCC, District Use Chart, shall meet the following standards unless otherwise regulated within this code. All residential dwellings shall meet the following provisions:

(1) All dwellings shall be placed on a permanent foundation with the space between the bottom of the home and the ground enclosed by concrete or an approved concrete product which can be either load-bearing or decorative.

(2) A dwelling shall be not less than 14 feet in width at the narrowest point of its first story.

(3) All designated manufactured homes located within the city on an individual lot of record, not within a manufactured home park, shall be new, not previously titled to a retail purchaser, no more than three years old on the date of installation, and composed of at least two fully enclosed parallel sections. (Ord. 2019-35 § 6)

10.47.030 Residential Design Guidelines.

The document entitled Wenatchee Residential Design Guidelines, as adopted by Resolution No. 2019-43, and any later edition thereof, shall be and hereby is adopted and incorporated into the Wenatchee City Code by this reference as if fully set forth herein. A copy of the most current adopted Residential Design Guidelines shall be maintained at the city clerk’s office and the city planning department available for review during normal business hours of the city. (Ord. 2019-35 § 6)

10.47.040 Accessory dwelling units (ADU).

All accessory dwelling units, where defined in WCC 10.08.040 and where allowed by Chapter 10.10 WCC, District Use Chart, shall meet the following standards unless otherwise regulated within this code:

(1) Purpose. The purpose of this section is:

(a) To regulate the establishment of accessory dwelling units within or in conjunction with single-family dwellings while preserving the character of single-family neighborhoods;

(b) To make it possible for adult children to provide care and support to a parent or other relatives in need of assistance;

(c) To provide increased security and companionship for homeowners;

(d) To provide the opportunity for homeowners to gain the extra income necessary to help meet the rising costs of home ownership; or to provide for the care of disabled persons within their own homes.

(2) Standards for All Accessory Dwelling Units, Including Those Attached to the Main Residence and Those That Are in a Separate Building but on the Same Property.

(a) Form. An ADU may be created within, or detached from, any existing or new single-family dwelling as a subordinate use. Dwelling units that are physically separated from the primary structure, that is, in a separate building, are “detached accessory dwelling units” (DADUs).

(b) Number. No more than one ADU may be created per legal lot of record.

(c) Occupancy. Only the property owner, which shall include title holders and contract purchasers, may apply for an ADU. For properties in the RS, RL, and RF zones, the property owner shall occupy either the primary dwelling or the ADU as their principal residence for at least six months of the year.

(d) Minimum Parking. A minimum of three parking spaces shall be provided for the principal and accessory dwelling units. On nonarterial streets where on-street parking is available (as approved by the city engineer) abutting the lot, only two off-street spaces shall be provided for the principal and accessory dwelling units.

(e) Maximum Size. In no case shall an ADU be larger than 50 percent of the habitable floor area of the principal dwelling, nor more than 800 square feet of gross floor area.

(f) Living Facilities. The ADU shall include, at a minimum, kitchen, bathroom and sleeping facilities.

(g) Entrance Location. If a separate outside entrance is necessary for an ADU located within the primary dwelling, that entrance shall be located either on the rear or side of the building.

(h) Home Occupations. A home occupation may be permitted in either the primary dwelling or the ADU but not in both if otherwise allowed in the WCC.

(i) Utilities. Utilities for an ADU shall be metered jointly with the primary dwelling except as otherwise required by ordinance.

(j) Addressing. An address shall be assigned by the city at the time of building permit issuance.

(k) Covenants. The property owner shall file a restrictive covenant with Chelan County’s auditor’s office for the subject property prior to final building inspection approval for the ADU. The recorded information shall:

(i) Identify the address of the property;

(ii) State that the owner(s) must reside in either the principal or accessory dwelling unit if located in the RS, RL, or RF zoning districts;

(iii) State that the owner(s) will notify any prospective purchasers of the limitations of the ADU;

(iv) State that the ADU shall not be subdivided or otherwise segregated in ownership from the primary dwelling unit; and

(v) Provide for the removal of the ADU if any of the requirements of this title are violated.

(l) Usable Open Space. No additional open space is required for the ADU or DADU. Lots containing an ADU or DADU must demonstrate compliance with the open space standards for single-family residences as set forth in WCC 10.47.050(2)(e) before an ADU or DADU can be legally established.

(3) Standards for All Detached Accessory Dwelling Units (DADU).

(a) Setbacks. DADUs shall meet rear and side accessory structure setback requirements and shall be set back equal to or further than the primary dwelling from the front property line.

(b) Maximum Height.

(i) DADUs with a roof pitch of 6:12 or greater: 25 feet.

(ii) DADUs with a roof pitch of less than 6:12: 20 feet.

(iii) Special Side Setback Standards for DADUs. From a height of 15 feet at the minimum side setback, DADUs shall step back at a 45-degree angle away from the side property line as shown in Figure 10.47.040(3) below. Structures set back further than the minimum side setback shall not encroach into the setback/daylight plane.

10.47.050 Single-family dwellings.

All single-family dwellings, where defined in WCC 10.08.055 and where allowed by Chapter 10.10 WCC, District Use Chart, shall meet the following standards unless otherwise regulated within this code:

(1) Purpose.

(a) To enhance the character of the street and neighborhood.

(b) To maintain “eyes on the street” for safety to pedestrians and to create a more welcoming and interesting streetscape.

(c) To deemphasize garages and driveways as major visual elements along the street.

(d) To provide usable open space for residents.

(2) Standards.

(a) Entry Standards.

(i) Clear and obvious pedestrian access between the sidewalk (or the street if there is no sidewalk) and the building entry is required for new dwellings. The driveway may be used for pedestrian access.

(ii) All new dwellings shall provide a covered pedestrian entry with minimum weather protection of four feet by four feet (a covered porch or recessed entry).

(iii) See the street setback exception for roofed porches and covered entries in WCC 10.46.080(2)(a)(iii).

(b) Driveway Standards.

(i) Minimum and maximum driveway widths for single-family houses facing a public street as measured at the property/right-of-way line are set forth in Table 10.47.050(2)(b) below. Paved areas for vehicle storage or other uses may be wider if they are no less than five feet from the street property/right-of-way line.

(c) Garage and Carport Setbacks. Garages and carports are subject to the setback standards in Chapter 10.46 WCC.

(d) Garage Standards. Garages (attached or detached) may occupy no more than 50 percent of the width of the ground-level facade facing the street. Garage doors may exceed this limit up to a maximum of 65 percent of the width of the ground-level facade facing the street provided at least two of the following design details are utilized:

(i) A decorative trellis over at least the entire width of the garage door(s).

(ii) A window or windows are placed above the garage on a second story or attic wall.

(iii) A balcony that extends out over the garage and includes decorative support columns.

(iv) Utilizing all single vehicle car doors as an alternative to wider garage doors suitable for two-car garages.

(v) Windows on the garage door.

(vi) Decorative details on the garage door. Standard squares on a garage door will not qualify as a decorative detail.

Garage design detail examples.

A decorative trellis over the garage door.

A balcony over the garage, single doors (instead of a wider double door), and windows above the garage on a second story.

A balcony over garage with decorative support columns.

(e) Standards for Minimum Usable Open Space.

(i) All new single-family dwelling units shall provide a contiguous open space to the side or rear of the dwelling with a minimum dimension of 15 feet on all sides. This space may not be used for vehicle or other large object storage but be available for human activity. The open space may be in the street setback if facing a private lane.

(ii) The open space(s) shall be equivalent to 10 percent (minimum) of the lot area. For example, a 4,000-square-foot lot would require a contiguous open space of at least 400 square feet, or 20 feet by 20 feet in area. Figure 10.47.050(2)(e) illustrates some configurations that comply for residences with alley access.

(iii) Drive aisles shall not count in the calculations for usable open space.

(iv) Additions shall not create or increase any nonconformity with this standard.

Figure 10.47.050(2)(e)

Examples of how to provide the minimum amount of usable open space.

(f) Multiple Single-Family Dwellings on One Lot. Multiple single-family dwellings may be placed on one lot provided the dwellings are located and designed in a manner so that the lot could be subdivided in the future and meet applicable lot dimensions, setbacks, and lot coverage standards applicable to the zoning district and other applicable standards in this title and WCC Title 11. The burden of proof for demonstrating compliance with the applicable standards for the potential short subdivision shall be on the applicant. Submittal requirements will therefore exceed those for a standard building permit. Additional information includes, but may not be limited to, a site plan that includes the “proposed” lot lines, access and utilities, any applicable easements, dimensions, and any other applicable information necessary to demonstrate compliance. Permitting multiple single-family dwellings on a single lot in no way guarantees the ability to subdivide in the future. Future proposed land divisions would need to meet the standards in place at the time of application. (Ord. 2020-35 § 3 (Exh. A); Ord. 2019-35 § 6)

10.47.060 Single-family – Cluster.

All single-family cluster developments, where defined in WCC 10.08.055 and where allowed by Chapter 10.10 WCC, District Use Chart, shall meet the following standards unless otherwise regulated within this code:

(1) Single-family cluster developments are subject to the specialized lot dimension and lot coverage standards in WCC 10.46.020 that allow for lot sizes close to 50 percent of the size of standard lots. However, single-family cluster developments are subject to the standard maximum building height limits and maximum density prescribed for the applicable zone along with the standards for single-family dwellings in WCC 10.47.050.

(a) All such lot reductions shall be compensated for by an equivalent amount of land area in open space to be preserved and maintained for its scenic value, for recreation, or conservation purposes. The open space shall be clearly labeled and numbered as a tract with the following language inserted on any and all plats filed for record:

This tract is held in reserve as a permanent open space and shall not be considered as a building lot, or encroached upon in any manner.

(b) The open space created and set aside shall remain for preservation, recreation and conservation purposes, and shall be accessible without trespassing on private property, to all residents of the subdivision or, where the land has been deeded to the city of Wenatchee, to the public.

(2) As an alternative to the cluster provisions in subsection (1) of this section, lots may be exempted from minimum lot area, depth, width, and rear setback standards, provided they are arranged in clusters of four to 12 dwelling units around a centralized common open space and meet the following standards:

(a) Development parameters based on compliance with the provisions herein shall be placed on the final plat or final unit lot subdivision.

(b) Cluster single-family developments shall meet zoning district density standards.

(e) Site Design and Orientation. Dwellings within a cluster development shall be oriented to promote a sense of community, both within the development and, with respect to the larger community, outside of the development. A cluster subdivision shall not be designed to “turn its back” on the surrounding neighborhood by locating rear yards to face a public street.

(i) Clear and obvious pedestrian access between the sidewalk (or the street if there is no sidewalk) and the dwelling entry is required.

(ii) All new dwellings adjacent to a street shall meet the Residential Design Guidelines, especially Section C.1 (Ground related units facing streets, common pathways, or common open space), Section C.2.1 (Pedestrian connectivity within multi-unit residential development with more than one building) and Section E.5.1 (Building entrances: configuration and details).

(iii) Common open space shall be provided in a centrally located focal area for the development and abut at least 50 percent of the dwellings in the cluster subdivision (see subsection (2)(g) of this section). Direct access to the common open space shall be provided for each dwelling by a paved walkway. See also Residential Design Guideline Section D.3 (Residential open space elements).

(iv) One existing single-family dwelling may be incorporated into a cluster development. Nonconforming residences with respect to architectural standards shall be permitted.

(v) A cluster development may contain one community building that is clearly incidental in use and similar in size and architectural design of the dwellings. Such community building shall be commonly owned by the residents.

(v) Fences are not allowed within any common open space area.

(vi) Common open space shall be located in a separate tract or tracts and owned in common by all property owners.

(h) Private Open Space. Each dwelling shall include a minimum of 400 square feet of private open space (in addition to common open space). The private open space shall have no dimension less than 10 feet, be located adjacent to the unit which it serves and feature direct access to the private open space via door. Examples include a semi-private garden space between a dwelling and the common open space.

(i) Surface water management facilities may be included in the required private and common open space areas provided they are designed to provide functional recreational uses for the residents.

(j) Driveway, Access, Parking, and Garages.

(i) Dwellings adjacent to a street are subject to applicable driveway and garage standards for single-family dwellings in WCC 10.47.050.

(ii) Parking and garages for individual dwellings may be configured separately on each lot or dwelling site (attached or detached) or clustered in shared parking areas.

(iii) Parking areas and garages (individual or shared) shall not be sited adjacent to common open spaces. The director may allow exceptions where site and/or building design features are integrated to minimize the impacts of garages and parking areas on the function and character of the common open space.

(iv) Where parking areas and garages are provided on each dwelling lot or site, shared private lanes may be used to access up to six dwelling units. Shared private lanes are subject to the private lane standards in WCC 11.20.020, except:

(A) Maximum length: 150 feet.

All single-family courtyard developments, where defined in WCC 10.08.055 and where allowed by Chapter 10.10 WCC, District Use Chart, shall meet the following standards unless otherwise regulated within this code:

(1) Purpose. To allow greater flexibility to integrate infill single-family lots served by a shared private lane.

(2) Standards.

(a) Maximum number of lots served by a shared private lane: six (this includes lots fronting the street on either side of the private lane as shown in Figure 10.47.070(3)).

(b) Shared private lanes are subject to the private lane standards in WCC 11.20.020, except:

(i) Maximum length: 150 feet (see Figure 10.47.070(3) for examples).

(ii) Minimum width: 15-foot paved lane within a 20-foot-wide easement.

(iii) Maximum number of lots: six in a single-family courtyard development.

(c) Setback Standards and Options for Lots Served by a Shared Private Lane.

Figure 10.47.090(1)(b)
Cottage housing site plan example.

(2) Standards.

(a) Cottage housing development options include ownership, rental, condominium, and subdivision.

(b) Subdivision. Where a cottage housing development involves a subdivision, development parameters as determined by the city shall be placed on the final plat or final unit lot subdivision.

(c) Minimum and Maximum Number of Cottages.

(i) A single cottage housing development shall include a minimum of four dwelling units.

(ii) Four to 12 cottage structures may make up a cluster (a grouping of cottages situated around a common open space or pedestrian circulation network, each with an entry facing the courtyard or pedestrian system).

(d) Maximum Cottage Size. The total floor area for a cottage shall be no greater than 1,200 square feet; provided, the ground floor is not greater than 800 square feet.

(e) Density. For the purposes of complying with the maximum density of the applicable zoning district, each cottage shall be counted as one-half dwelling unit. For example, for an existing lot that qualifies for three dwelling units would qualify for six cottages.

(f) Setbacks.

(i) Cottages built along streets are subject to the applicable street setbacks in Chapter 10.46 WCC.

(ii) Cottages built adjacent to side property lines are subject to the applicable side setback.

(iii) Cottages built along rear property lines of the parent lot(s) shall maintain a 10-foot minimum setback in the RS and RL zones and a five-foot minimum setback in all other applicable zones.

(iv) The minimum internal setback between cottages is 10 feet, except that two cottages may share a common wall as in a duplex configuration. Within a given development, up to one-half of the cottages may feature the shared wall/duplex configuration.

(g) Site Design and Orientation. Dwellings within a cottage housing development shall be oriented to promote a sense of community, both within the development and, with respect to the larger community, outside of the cottage project. A cottage development shall not be designed to “turn its back” on the surrounding neighborhood by locating rear yards to face a public street.
