115.07 Accessory Dwelling Units

Two (2) accessory dwelling units (ADUs), including either one (1) attached ADU and one (1) detached ADU, or two (2) of either type, are permitted per single-family dwelling; provided, that an accessory dwelling unit shall not be considered a “dwelling unit” in the context of Special Regulations in Chapters 15 through 56 KZC which limit the number of detached dwelling units on each lot to one (1). Accessory dwelling units must be consistent with the following standards:

1.    Occupancy Limitations – Occupancy limitations for ADUs shall be consistent with the provisions of the KMC Property Maintenance Code.

2.    Subdivision – A property containing a detached accessory dwelling unit shall not be subdivided but may be segregated in ownership from the principal dwelling unit.

3.    Size – The square footage of the ADU shall not exceed 1,200 square feet of gross floor area. For attached ADUs, if the accessory unit is completely located within existing gross floor area on a single floor, the Planning and Building Director may allow increased size in order to efficiently use all floor area. When calculating the square footage of the ADU see KZC 5.10.340, definition of “gross floor area.” The gross floor area shall not include:

a.    Area with less than five (5) feet of ceiling height, as measured between the finished floor and the supporting members for the roof.

b.    Covered exterior elements such as decks and porches; provided, the total size of all such covered exterior elements does not exceed 200 square feet. See KZC 115.08 for additional size and height limitations.

4.    Location – An accessory dwelling unit may be added to or included within the principal unit, or located in a detached structure. Detached accessory dwelling units located on lots approved using the historic preservation subdivision regulations must be located behind the historic residence. Accessory dwelling units must conform with the setbacks, height restrictions, lot coverage and other applicable zoning regulations required for single-family dwellings in the applicable use zone; except as modified by KZC 115.42 and 115.115(3)(o). In addition, detached accessory dwelling units must be fully contained in a separate structure that is detached from the principal unit and any attached accessory dwelling unit. A detached accessory dwelling unit may not share a common roof structure with the principal unit and/or attached accessory dwelling unit.

5.    Entrances – The primary entrance to the accessory dwelling unit shall be located in such a manner as to be clearly secondary to the main entrance to the principal unit and shall not detract from or alter the single-family character of the principal unit.

6.    Parking – On lots with more than one (1) accessory dwelling unit, there shall be one (1) off-street parking space provided unless:

a.    On-street parking is available within 600 feet of the subject property; or

b.    The property is located within one-half mile of transit service with 15-minute headways during commute hours.

7.    Applicable Codes – The portion of a single-family dwelling in which an accessory dwelling unit is proposed must comply with all standards for health and safety contained in all applicable codes, with the following exception for ceiling height. Space need not meet current International Building Code (IBC) ceiling height requirements if it was legally constructed as habitable space.

8.    Permitting

a.    Application

1)    The property owner shall apply for an accessory dwelling unit permit with the Planning and Building Department. The application shall include an affidavit signed by the property owner agreeing to all the general requirements outlined in this section.

In the event that proposed improvements in the accessory dwelling unit do not require a building permit, a registration form for the unit must be completed and submitted to the Planning and Building Department.

2)    The registration form as required by the City shall include a property covenant. The covenant must be filed by the property owner with the City for recording with the King County Recorder’s Office to indicate the presence of the accessory dwelling unit, and reference to other standards outlined in this section. The covenant shall run with the land as long as the accessory dwelling unit is maintained on the property.

3)    If an ADU was or is created without being part of a project for which a building permit was or is finaled, an ADU inspection will be required for issuance of an ADU permit. The ADU inspection fee will cover a physical inspection of the ADU. This fee will be waived if the ADU existed on January 1, 1995, and the ADU permit is applied for by December 31, 1995.

b.    Eliminating an Accessory Dwelling Unit – Elimination of a registered accessory dwelling unit may be accomplished by the owner filing a certificate with the Planning and Building Department, or may occur as a result of enforcement action.

c.    Appeals. The decision of the Planning Official is appealable using the applicable appeal provisions of Chapter 145 KZC.

115.08 Accessory Structure (Detached Dwelling Unit Uses Only)

Structures, to be used as a tool shed, greenhouse, private garage, accessory dwelling unit, barn or similar use are permitted. The total size of all such structures may not exceed the gross floor area of 1,200 square feet plus 10 percent of the lot area that exceeds 7,200 square feet. An accessory structure which contains an accessory dwelling unit must also comply with KZC 115.07 which may further limit its size.

The gross floor area shall not include area with less than five feet of ceiling height, as measured between the finished floor and the supporting members for the roof. The height (roof peak elevation) of an accessory structure, including ADUs, in all residential zones, may not exceed the maximum height allowed by the underlying zone or 15 feet above the existing height (roof peak elevation) of the primary residence, whichever is less. This height limitation may be more restrictive than KZC 83.180(2) for ADUs in the shoreline jurisdiction and in the event of a conflict between this provision and KZC 83.180(2), this provision shall prevail based on KZC 83.70(2).

115.42 Floor Area Ratio (F.A.R.) Calculation for Detached Dwelling Units in Low Density Residential Zones and Attached Dwelling Units in PLA 3C

The intent of these F.A.R. regulations is to limit the perceived bulk and mass of residential structures as they relate to the right-of-way and adjacent properties and to ensure houses are proportional to lot size. The design incentives in subsection (4) of this section are provided to encourage more interesting design and location of building massing toward the center of each lot, away from neighboring properties.

1.    Gross floor area for purposes of calculating F.A.R. and maximum floor area for detached dwelling units in low density residential zones and attached dwelling units in PLA 3C shall include the entire area within the exterior walls for each level of the structure. It shall also include the area of all carports, measured as the area of the carport roof. It shall not include the following:

a.    Attic area with less than five feet of ceiling height, as measured between the finished floor and the supporting members for the roof.

b.    Floor area with a ceiling height less than six feet above finished grade. The ceiling height will be measured to the top of the structural members for the floor above. The finished grade will be measured along the outside perimeter of the building (see Plate 23). For window wells, finished grade will be measured at the outside perimeter of a window well only when it is designed and constructed to the minimum dimensions required by the current building code adopted by the City of Kirkland.

c.    On lots less than 8,500 square feet, the first 500 square feet of an accessory dwelling unit or garage contained in an accessory structure, when such accessory structure is located more than 20 feet from and behind the main structure, or 10 feet from and behind the main structure if the accessory structure contains an accessory dwelling unit (see subsection (3) of this section for additional information on the required distance between structures); provided, that the entire area of an accessory structure, for which a building permit was issued prior to March 6, 2007, shall not be included in the gross floor area used to calculate F.A.R. For purposes of this section, “behind” means located behind an imaginary plane drawn at the back of the main structure at the farthest point from, and parallel to, the street or access easement adjacent to the front facade.

d.    On lots greater than or equal to 8,500 square feet, the first 800 square feet of an accessory dwelling unit or garage contained in an accessory structure, when such accessory structure is located more than 20 feet from and behind the main structure, or 10 feet from and behind the main structure if the accessory structure contains an accessory dwelling unit (see subsection (3) of this section for additional information on the required distance between structures); provided, that the entire area of an accessory structure, for which a building permit was issued prior to March 6, 2007, shall not be included in the gross floor area used to calculate F.A.R. For purposes of this section, “behind” means located behind an imaginary plane drawn at the back of the main structure at the farthest point from, and parallel to, the street or access easement adjacent to the front facade.

e.    Uncovered decks.

f.    Covered decks, porches, and walkways that are open on at least three sides or have a minimum 50 percent of the perimeter of the deck, porch, or walkway open. Deck, porch, or walkway perimeters with the following characteristics are considered open:

1)    Have no walls of any height; and

2)    Have no guard rails taller than the minimum height required by the Building Code.

g.    One exemption of 100 square feet if the dwelling unit has an internal staircase and/or an area with a ceiling height greater than 16 feet.

2.    Floor area with a ceiling height greater than 16 feet shall be calculated at twice the actual floor area toward allowable F.A.R. The ceiling height for these areas will be measured to the top of the structural members for the floor above or, if there is no floor above, to the bottom of the structural members for the roof.

3.    Separate structures will be regulated as one structure if any elements of the structures, except for the elements listed in subsection (3)(b) of this section, are closer than 20 feet to each other, or closer than 10 feet if the structures contain an accessory dwelling unit.

a.    Two structures connected by a breezeway or walkway will be regulated as one structure if any element of the breezeway or walkway is higher than 10 feet above finished grade.

b.    Elements of structures that may be closer than 20 feet to each other, or 10 feet if the structures contain an accessory dwelling unit, are:

1)    Elements of a structure no higher than 18 inches above finished grade;

2)    Chimneys, bay windows, greenhouse windows, eaves, cornices, awnings and canopies extending no more than 18 inches from the wall of a structure;

3)    Stairs extending no more than five feet from the wall of a structure;

4)    For structures not containing an accessory dwelling unit, porches extending no more than five feet from the wall of a structure if:

a)    The porch is no higher than one story and the finished floor of the porch is no more than four feet above finished grade;

b)    Three sides of the porch are open other than railings and solid walls no higher than 42 inches;

c)    No deck, balcony, or living area is placed on the roof of the porch;

d)    The length of the porch does not exceed 50 percent of the wall of the structure to which it is attached;

e)    Porch eaves may extend an additional 18 inches from the edge of the porch.

4.    Design-Based F.A.R. Bonus

a.    An additional five percent F.A.R. above the maximum F.A.R. for the zone will be allowed for a subject property if at least two of the design elements below are used in the design and construction of dwelling units on the subject property:

1)    With the exception of accessory features, all roof forms for all structures consist of ridgelines peaked near the center of the structure, with a minimum pitch of four feet vertical to 12 feet horizontal.

2)    All structures are set back from side property lines by at least seven and one-half feet.

3)    The gross floor area of any floor above ground floor, including any accessory structures with floors above ground floor, shall be reduced by a minimum of 15 percent of the floor area of the ground floor on a per-structure basis.

b.    The above design-based F.A.R. bonus cannot be combined with any other F.A.R. incentive in this code or the Kirkland Municipal Code.

115.43 Garage Requirements for Detached Dwelling Units in Low Density Zones

1.    Purpose and Intent – The intent of these regulations is to minimize the appearance of the garage when viewing the front facade of a house. To achieve this result, the following principles apply:

a.    The garage doors, whenever practicable, should not be placed on the front facade of the house;

b.    If the garage doors are on the front facade, the garage should be set back from the plane of the front facade closest to the street, access easement or tract;

c.    The width of the garage face generally should be no more than the width of the remainder of the front facade; and

d.    Garages with garage doors perpendicular to the street, access easement or tract (side-entry garages) should not have a blank wall on the front facade.

2.    General Requirements

a.    Detached dwelling units served by an open public alley, or an easement or tract serving as an alley, shall enter all garages from that alley;

b.    Side-entry garages shall minimize blank walls by incorporating architectural details or windows on the front facade that complement the features of the remainder of the front facade.

3.    Additional Requirements for Garages with Garage Doors on the Front Facade of the Detached Dwelling Unit

a.    The garage may not extend closer to the abutting right-of-way than any other ground floor portion of the front facade of the detached dwelling unit (not including covered entry porches approved under KZC 115.115(3)(n)).

b.    The garage width shall not exceed 50 percent of the total width of the front facade. (This standard shall not apply if the lot width, as measured at the back of the required yard for the front facade, is less than 55 feet.) The garage width shall be measured between the outermost edges of all garage doors on the front facade.

c.    For purposes of this section, the width of the front facade shall not include those items located along the side facades described in KZC 115.115(3)(d), even if they are outside of a required yard.

4.    Exemptions – The following are exempt from the requirements of subsection (3) of this section:

a.    Houses on flag lots;

b.    Houses with below-grade garages. For purposes of this exemption, a “below-grade garage” is one that has at least 75 percent of the area of the garage doors below the midpoint elevation(s) of the street, access easement or tract as it passes along the front of the garage.

5.    Modification of Requirements – The Planning Official may modify the requirements of this section if the following criteria are met:

a.    The modification is necessary because of the size, configuration, topography or location of the subject property, or the location of a preexisting improvement on the subject property that conformed to the Zoning Code in effect when the improvement was constructed. For purposes of this modification from requirements, a carport shall not be considered a preexisting improvement; and

b.    The modification supports the purpose and intent of the garage setback regulations; and

c.    The modification includes design details that minimize the dominant appearance of the garage when viewed from the street, access easement or tract (for example, casings; columns; trellises; windows; surface treatments or color; single-stall doors; door offsets; narrowed driveway widths; and/or enhanced landscaping); and

d.    The modification will not have any substantial detrimental effect on nearby properties and the City as a whole.

115.59 Height Regulations – Calculating Average Building Elevation (ABE)

1.    General – ABE shall be calculated using the following formula:

ABE = (Mid-point Elevation) x (Length of Segment) +
(Mid-point Elevation) x (Length of Segment)
(Length of Segment) + (Length of Segment)

(See Plates 17A and 17B. The permit applicant may choose whether to use the simplified calculation as depicted in Plate 17A, Option 1, or the more complicated calculation as depicted in Plate 17B, Option 2.)

For both options, the ABE segments shall include decks and porches, unless the deck or porch has no walls at or below the deck level and no roof above the deck or porch, as well as cantilevered portions of a building which enclose interior space.

For Option 1, those items allowed to extend into required yards through KZC 115.115(3)(d) shall not be included within the square or rectangle.

For Option 2, those items allowed to extend into required yards through KZC 115.115(3)(d) shall be included in the wall segments.

For calculation of mid-point elevation, existing predevelopment grades shall be used, unless fill has been placed on the site, whether legally or illegally, within a 10-year period prior to the development application, in which case the grades prior to the placement of the fill shall be used.

2.    Attached but Independent Building Units – When a building or structure contains townhouses or other attached but otherwise independent building units, the ABE is calculated separately for each unit.

3.    Partially Underground Structures or Improvements – Building wall segments more than four (4) feet in height above finished grade and enclosing interior space shall be included in the height calculations.

(Ord. 4121 § 1, 2008; Ord. 4072 § 1, 2007)

115.60 Height Regulations – Exceptions

1.    General – No element or feature of a structure, other than as listed in subsection (2) of this section, may exceed the applicable height limitation established for each use in each use zone in Chapters 15 through 56 KZC.

For properties within jurisdiction of the Shoreline Management Act, see Chapter 83 KZC.

2.    Exceptions

a.    Detached Dwelling Units

1)    Vents and chimneys for a detached dwelling unit may exceed the maximum height limit.

2)    Skylights may exceed the height limit by a maximum of six inches.

3)    Rod, wire and dish antennas, to the extent they do not constitute personal wireless service facilities, which are subject to the provisions of Chapter 117 KZC, may not be placed above the maximum height allowed for any structure unless approved by the Planning and Building Director. The City will approve the application if it can be demonstrated that views across the subject property are not substantially impaired and that the antenna must be placed above the roofline in order to function properly. The decision of the Planning and Building Director in approving or denying a rod, wire, or dish antenna may be appealed using the appeal provision, as applicable, of Process I, KZC 145.60.

For the purposes of this subsection, “dish antenna” includes any antenna, whether or not it is of solid or mesh construction, designed or constructed so that the horizontal dimension of its microwave reflector or collector face equals or exceeds 30 percent of its vertical dimension. The phrase “rod or wire antenna” includes those antennas not falling within the definition of dish antenna and antennas for use by licensed amateur radio operators.

4)    Solar panels on flat roof forms (less than 2:12) may exceed the height limit by a maximum of six inches.

b.    Other Structures

115.107 Public Utility, Electrical Transmission Lines

1.    Purpose – The purpose of this section is to regulate proposals for new electrical transmission lines and to address the impacts associated with such facilities on surrounding areas by minimizing visual and environmental impacts. These facilities are necessary to support growth in the community but typically do have negative impacts in some locations and conditions. The review process is intended to provide the City with a mechanism to weigh alternatives and impacts associated with a project. Because these facilities typically cross multiple zoning districts, this section also provides a consistent and consolidated review process.

2.    General – The following regulations shall apply to the installation of new electrical transmission lines.

3.    Required Review – Applications for new electrical transmission lines shall be reviewed pursuant to Process IIA, described in Chapter 150 KZC.

4.    Decisional Criteria – In addition to the criteria established in Chapter 150 KZC, the City may approve an electrical transmission line only if it finds that, based on the siting and design analysis, the applicant has demonstrated that the proposal, to the extent technically and operationally feasible, has been sited and designed to minimize and mitigate impacts to:

a.    Critical areas, critical area buffers, and significant trees as regulated in applicable chapters of the KZC; and

b.    Views from public properties and rights-of-way that are designated in the Comprehensive Plan; and

c.    Schools and residential areas.

5.    Siting and Design Analysis – As part of an application, the applicant shall submit a siting and design analysis describing how the proposed route and project design was selected. The analysis shall include an assessment of:

a.    How the proposal addresses the City’s decisional criteria and justifies the proposed siting and design relative to those criteria;

b.    Potential technologies and design features that would mitigate the visual and environmental impacts associated with the transmission line;

c.    Potential technologies and design features that would mitigate radio frequency interference with existing high-technology uses identified along the proposed route in compliance with applicable NESC standards, IEEE guidelines and FCC requirements.

Examples of mitigating technologies and design features include: design, placement and height of the support structures; landscaping and screening; tree retention and restoration; noise reduction; and specific construction techniques. The analysis shall be limited to those alternatives and design features that meet the system needs of the project.

115.120 Rooftop Appurtenances

The intent of these rooftop appurtenance regulations is to specify height allowances for such items above the maximum height of structure. Regulations for rooftop appurtenances recognize that the rooftop can be a practical place for building utilities and that access to rooftops often requires additional height.

1.    Scope – The regulations contained in this section apply to all construction except: (a) single-family residential, and (b) personal wireless service facilities regulated by Chapter 117 KZC.

For properties within jurisdiction of the Shoreline Management Act, see Chapter 83 KZC.

2.    Abandonment – Rooftop appurtenances which are abandoned or no longer serve the building or tenant space with which they are associated shall be removed by the building owner within 90 days of the date they were abandoned or discontinued service. Appurtenances associated with buildings or tenant spaces which are vacant but which are undergoing renovation and/or are available for lease or rent shall not be considered abandoned.

3.    Required Screening for Rooftop Appurtenances

a.    New construction shall, to the extent feasible, visually screen rooftop appurtenances by incorporating them into the roof form, or by using architectural designs such as clerestories having a slope of at least three (3) feet vertical to 12 feet horizontal or roof wells. Such roof forms and architectural designs may extend five (5) feet above the height limit (see Plate 30).

b.    New or replacement appurtenances on existing buildings and new appurtenances on new buildings where compliance with subsection (3)(a) of this section is not feasible shall be surrounded by a solid screening enclosure equal in height to the appurtenances being screened. The screen must be integrated into the architecture of the building.

c.    A rooftop appurtenance screened by alternative measures, including but not limited to landscaping maintained at a height equal to the height of the appurtenance, painting to match the building roof and/or façade, or the use of pre-manufactured self-screening appurtenances, is exempt from the requirements of subsections (3)(a) and (b) of this section if the Planning Official determines that such alternative screening will be as effective in minimizing rooftop clutter as a solid screening enclosure.

d.    Exemptions

1)    Rod, wire, and dish antennas approved pursuant to KZC 115.60(2) are exempt from the requirements of subsections (3)(a) and (b) of this section where screening would interfere with the effective operation of these antennas.

4.    Allowable Height and Size – Rooftop Appurtenances

a.    Any rooftop appurtenance may exceed the maximum height of structure by a maximum of four (4) feet if the area of all appurtenances and screening does not exceed 10 percent of the total area of the building footprint (see Plate 31). Elevators and equipment and/or stair enclosures allowed under subsection (4)(b) of this section shall be included in the area calculation towards the maximum 10 percent.

b.    For stacked dwelling units and commercial buildings, rooftop appurtenances necessary to access rooftop amenities, such as elevators and associated equipment and/or stair enclosures, may extend above the maximum height of structure for the zone beyond the allowance in subsection (4)(a) of this section, provided:

1)    The elevator and associated equipment and/or stair enclosure height is the minimum necessary for rooftop access and does not exceed 15 feet above the maximum height of structure. For buildings with a height limit of 85 feet or taller, the additional height allowance for elevators and associated equipment and/or stair enclosures shall be 20 feet. The height allowances for elevators and/or stair enclosures shall be measured above the roof of the rooftop amenity room if they provide access to a rooftop amenity room. See also subsection (4)(b)(4) of this section.

2)    Elevators and associated equipment may include an enclosed entry/exit vestibule matching the height of the elevator, but not exceeding the minimum area required by the building code.

3)    The stair enclosure, including the top landing of stairs, does not exceed the minimum area required by the building code.

4)    Rooftop appurtenances necessary to access rooftop amenities, such as elevators and associated equipment and/or stair enclosures, proposed where the subject property is partially, or wholly, adjoining low-density residential zones may only be approved through the modification process in subsection (4)(c) of this section.

c.    The Planning Official may approve a modification to the standards of subsection (4)(a) of this section if:

1)    No reasonable alternative to the increased height or size exists, such as utilizing alternative equipment design or technology or locating the appurtenances at or below grade or within the structure, and the amount of increase and the size of the appurtenance and its screening is the minimum amount necessary; and

2)    The applicant submits accurate graphic representations or other information that demonstrate that:

a)    Views from adjoining properties will not be significantly blocked by the appurtenance(s); and

b)    Visibility of the appurtenances from adjoining properties and streets will be minimized; and

c)    Aesthetic impacts resulting from the increased height and/or area will be minimized through appropriate screening, architectural integration, and/or location or consolidation of the appurtenance(s); and

3)    The height of the appurtenance, except for elevators and associated equipment and/or stair enclosures, shall in no event exceed the height of the story immediately below the appurtenance; and

4)    In no event shall the total area occupied by rooftop appurtenances or enclosed within their screening exceed 25 percent the total area of the building footprint.

d.    The Planning Official shall not approve or deny a modification pursuant to subsection (4)(c) of this section without first providing notice of the modification request to the owners and residents of each adjoining property and providing opportunity for comment. Said comment period shall not be less than seven (7) calendar days. The fee for processing a modification request shall be as established by City ordinance.

5.    Optional Locations – As an option to placing appurtenances on the roof, appurtenances may be located in a parking structure, subject to the following:

1)    The appurtenances are located or screened in such a manner that they are not visible from adjoining properties or rights-of-way; and

2)    The appurtenances will not violate KZC 115.95 (Noise Regulations) or KZC 115.100 (Odor) or create undue heat or vibration on the adjoining property.

3)    If the parking structure would otherwise contain 10 or more parking stalls, the parking may be reduced by the amount necessary, but by no more than two (2) parking stalls, to provide the physical space required to accommodate the appurtenances. See also KZC 115.115(3)(p).

6.    Review Authority – If a rooftop appurtenance modification requiring approval through a Planning Official decision pursuant to subsection (4)(c) of this section is part of a proposal that requires additional approval through Design Review, Process I, Process IIA or Process IIB, the entire proposal shall be decided upon using that other process.

(Ord. 4855 § 1, 2023; Ord. 4720 § 1, 2020; Ord. 4252 § 1, 2010; Ord. 4121 § 1, 2008; Ord. 4072 § 1, 2007; Ord. 3954 § 1, 2004; Ord. 3919 § 1, 2003; Ord. 3814 § 1, 2001)
