Prior legislation: Ord. 2697.
The intent and purpose of off-street parking and loading requirements is to provide for well-designed, safe, and efficient off-street parking areas and encourage the use of transportation management systems to serve all land uses and thus help alleviate congestion on City streets. Every building hereafter erected, moved, reconstructed, or structurally altered shall provide off-street parking areas as provided in this chapter, and such parking areas shall be made permanently available and maintained for parking purposes. The City has the right to review access locations for public safety considerations.
(Ord. 2074 § 7.1, 1995; Ord. 2864 § 1 (Exh. A), 2024; Ord. 2887 § 2 (Exh. A), 2025; Ord. 2911, 3/5/2026)
Required off-street parking facilities shall be located as specified below. Where a distance is specified, such distance shall be the walking distance measured from the nearest point of the parking facility to the nearest point of the building that such facility is required to serve:
A. 
For dwelling units on the same lot as the building the parking will serve;
B. 
For multi-household developments containing three or more units: not more than 200 feet from the building the parking will serve;
C. 
For religious facilities, hospitals, bed and breakfast inns, rooming and boarding houses, and long-term care facilities: not more than 150 feet from the facility the parking will serve; and
D. 
For private recreational facilities in residential zones, parking shall be located on the same lot as the buildings or facilities it will serve. Parking on public streets shall not be counted toward parking requirements.
(Ord. 2476 § 5, 2008; Ord. 2840 § 6, 2024; Ord. 2864 § 1 (Exh. A), 2024; Ord. 2875 § 2, 2025; Ord. 2887 § 2 (Exh. A), 2025; Ord. 2911, 3/5/2026)
For development in existence prior to the adoption of the ordinance codified in this title which does not have sufficient off-street parking on the basis of the requirements in this chapter, the following regulations shall apply:
A. 
When an existing use or building is enlarged by 25 percent or less of the total floor area of the use or building, including any outdoor sales area, and when such expansion results in the requirement for additional parking, the requirements of this chapter shall apply only to the enlargement. If the use is enlarged more than 25 percent of the gross floor area including outdoor sales areas, the entire project shall comply in full with the parking requirements of this title;
B. 
When a preexisting use is terminated or changed, the area vacated shall not be occupied by a new use unless the number of required parking spaces are provided in full; and
C. 
When a preexisting building is remodeled or rehabilitated but not enlarged, the existing use of the building may continue without providing additional parking unless the proposed remodeling equals greater than 50% of the assessed value of the existing building, in which case the entire project shall comply in full with the parking requirements of this title.
(Ord. 2074 § 7.3, 1995; Ord. 2864 § 1 (Exh. A), 2024; Ord. 2887 § 2 (Exh. A), 2025; Ord. 2911, 3/5/2026)
A. 
Parking facilities shall be provided and maintained to accommodate motor vehicles and bicycles used by occupants, customers, clientele, and employees associated with the structure or use as required by this chapter. Parking may not be leased or otherwise made available to users not associated with the on-site use, residence or activity, except in the following circumstances:
1. 
The parking is being used by individuals that are patrons of a commercial or mixed-use district who park in one location as they shop or patronize multiple businesses in the vicinity (not to exceed four hours);
2. 
The parking spaces are not required spaces for the residential units on the premises. Required on-site parking spaces shall be provided for and made available to the tenants of residential units at all times.
B. 
When the unit of measurement determining the number of required parking spaces results in a fractional number of spaces, any fraction up to and including one-half shall be disregarded, and fractions over one-half shall require an additional parking space.
C. 
For facilities containing mixed uses, the off-street parking requirement shall be calculated pursuant to MTMC § 19.125.060.
D. 
The property owner shall be responsible for maintaining parking areas in good condition including traffic control devices, signs, lighting, fences, walls, surfacing materials, curbs, and railings. Areas shall be free of refuse and debris. All landscaping shall be kept in a healthy condition and properly maintained and replaced when necessary.
E. 
No obstructions shall be permitted within any designated parking space and circulation areas. No parking space may block access to other parking spaces unless the parking lot is supervised by an attendant with access to the keys of all vehicles.
F. 
The City of Mountlake Terrace, or Washington State Department of Transportation, may limit the number, location, and width of curb cuts along a public right-of-way.
G. 
Parking Area Improvements to Be Installed Prior to Granting of a Certificate of Occupancy. A certificate of occupancy for a new building or for a change of occupancy in an existing building shall not be issued until all surfacing, parking lot landscaping, and traffic control devices and any other required parking lot improvements are installed and completed as shown on the approved plans or the necessary guarantees provided.
H. 
Transportation Demand Management (TDM) Parking Reduction. Residential dwellings are not eligible for TDM parking reduction. The total number of required parking spaces may be reduced up to 25% for commercial uses when (1) the development is within one-third mile of the Mountlake Terrace Transit Center located at 236th Street SW and I-5 or (2) as approved by the Director, when the applicant provides some or all of the following TDM programs: vanpools, fleet ride, subscription bus, regular transit subsidy, and parking management programs such as carpooling; provided, that the applicant demonstrates that the use of these programs is likely to correspondingly reduce the need for the minimum number of parking spaces otherwise required by this chapter.
(Ord. 2074 § 7.4, 1995; Ord. 2569 § 2, 2011; Ord. 2669 § 2, 2015; Ord. 2864 § 1 (Exh. A), 2024; Ord. 2887 § 2 (Exh. A), 2025; Ord. 2911, 3/5/2026)
A. 
Parking Plans – General Requirements. Prior to the approval of a required land use permit and/or authorization, the applicant shall present evidence in writing that arrangements have been made to provide off-street parking and/or loading space in accordance with this chapter. Parking area plans shall be submitted to the Planning Department for their review. The required parking lot landscaping is described in Chapter 19.130 MTMC. Record of approval by the Planning Department shall be written on the face of the plan and filed with the City. If an applicant is required to submit an application that requires a public hearing, then the approval authority for the conceptual parking plan will be with the appropriate entity.
B. 
Parking Plans – Specific Design Standards.
1. 
Parking Restrictions. Parking of vehicles shall be restricted to within designated stalls; other surfaced areas where parking is prohibited such as an emergency vehicle access area shall be marked in a manner to prohibit parking.
2. 
Common Driveways. Common driveways shall be encouraged for adjacent lots in order to minimize the number of curb cuts along the street. To create a common driveway, adjacent property owners shall grant easements to each other on the common driveway. Such easements shall be recorded with the Snohomish County Auditor's Office and a copy provided to the City in connection with any permit application. See MTMC § 19.30.045I for shared driveway developmental bonus.
3. 
Street Access. Parking facilities shall be designed so exiting vehicles are not required to back into streets, other than an alley. This restriction does not apply for residential uses of less than four dwellings per lot on local streets or small-scale commercial development.
4. 
Entrances and Exits to Parking Areas. The City Engineer shall have the authority to fix the location, width, turning movements (right and left), and manner of approach of vehicular ingress or egress from a building or parking area to a public street and to alter existing ingress and egress as may be required to control street traffic in the interest of public safety and general welfare.
5. 
Internal Circulation. Internal circulation of the parking facility shall be so designed as to minimize in-and-out driving time, idling time, and time spent looking for a parking space and to accommodate a variety of vehicle sizes. Parking lots shall be designed to optimize pedestrian access to the lot and within the lot area. Safe pedestrian circulation shall be provided by use of signs, crosswalks, and walkways which are raised or otherwise designed to separate or protect pedestrians from vehicular traffic.
6. 
Drive-In Businesses. For any drive-in or drive-through service bay associated with a use such as a bank, gas station, or fast-food restaurant, there shall be provided stacking space for vehicles waiting for service which is sufficient to prevent any such vehicles from extending onto the public right-of-way. At least four stacking spaces shall be provided for each such service bay on the entrance side, and one space on the exit side. No bays designed to be entered from more than one direction shall be permitted.
7. 
Dimensional Requirements. The minimum dimensional requirements for parking stalls and aisle widths for standard, compact, and barrier-free parking are provided by the figures at the end of this section. The Director is authorized to develop, consistent with this chapter, any additional dimensional or similar standards that may be necessary for implementation of this chapter.
8. 
Modifications to Dimensional Requirements. Any parking stalls abutting a planter island, wall, column or other obstruction on the driver or passenger side of the vehicle shall provide an additional 12 inches of stall width above the minimum stall width requirement to provide a place to step. The additional width shall be distinguished by pedestrian walkway pavement striping. Columns or other obstructions may encroach up to six inches into the stall width in an area up to 24 inches from a corner of a parking space. In no case shall this reduce the width of the parking stall by more than six inches. The parking stall depth requirement may be reduced when vehicles overhang a walkway or landscaped area under the following conditions:
a. 
Wheel stops or curbs are installed;
b. 
The amount of stall depth reduction is limited to a maximum of two feet for standard parking spaces and compact spaces measured from the base of the face of the curb or wheel stop (see figures located at the end of this chapter); and
c. 
Any abutting walkway shall provide a minimum of three feet of unimpeded passageway for pedestrians and a minimum of four feet of unimpeded passageway where barrier-free access is provided beyond the overhang area.
9. 
All parking areas and paved surfaces within a site with more than six units shall be separated from landscaped areas by a curb or raised sidewalk in accordance with approved engineering requirements to protect landscape plant material, prevent soil or mulch in landscape areas from washing onto paved surfaces, protect asphalt pavement edges from crumbling, and/or direct surface water runoff, unless a curbless edge is essential for stormwater flow into a bioswale, rain garden or other LID stormwater feature. If a curbless design is needed, a concrete ribbon shall be provided along all parking spaces, and the landscaped area shall either be stabilized with ground cover plantings or be graded away from the pavement area to prevent soil and mulch washout onto pavement areas.
10. 
Compact Parking Stalls. Up to 50 percent of the required spaces may be designed and designated as compact stalls. Compact parking spaces shall be clearly identified by painting the word "COMPACT" in capital letters, a minimum of eight inches high, on the pavement at the base of the parking stall, centered between the striping.
11. 
Bicycles. Where provided, bicycle parking facilities shall be located near building entrances rather than in remote areas and shall not impede pedestrian or vehicle traffic flow or cause damage to landscaped areas.
12. 
Surface Treatment. All parking lots and driveways shall be surfaced in accordance with LID principles as prescribed in the approved engineering requirements. Surface treatment requirements for parking lots and driveways planned for heavier vehicle use shall be determined by the City Engineer. No gravel-surfaced parking lots are permitted.
13. 
Traffic Control Devices. All traffic control devices, such as parking stripes designating car stalls, directional arrows, signs, curbs, and other improvements, shall be MUTCD compliant and installed as approved. Paint or similar devices shall be used to delineate car stalls and directional arrows. Where pedestrian walks are used in parking lots for the use of foot traffic only, they shall be curbed or raised six inches above the lot surface.
14. 
Striping. All striping in off-street parking areas shall be installed per the requirements of this chapter and maintained in good condition.
15. 
Lighting. Lighting shall be provided in accordance with approved engineering requirements as necessary for safety of circulation on the site. Any lighting provided shall be designed so as to prevent light from directly illuminating adjacent properties and not create a nuisance or safety hazard to passing traffic.
16. 
Landscaping and Irrigation. Parking areas shall include landscaping and irrigation improvements as required by Chapter 19.130 MTMC.

Applies to either standard or compact spaces. When a parking space is located next to a building with a projection or overhang, the parking surface must be separated by at least three feet horizontally from that building wall by a curb or other approved barrier. The aforesaid requirement does not apply in front of a vehicular garage door, and does not apply when the projection or overhang provides at least eight feet of clearance above the grade of the parking surface.
2
Alternative provisions for bicycle storage must be demonstrated per MTMC § 19.125.130 to apply these dimensions.
3
This space must be clear of obstructions such as, but not limited to, water heaters or mechanical equipment.
4
This space must be clear of obstructions such as, but not limited to, water heaters or mechanical equipment; provided, that such obstructions may extend up to 36 inches maximum into one of the parking spaces.
(Ord. 2486 § 4, 2008; Ord. 2698 § 3, 2016; Ord. 2729 § 19, 2018; Ord. 2792 § 19, 2021; Ord. 2864 § 1 (Exh. A), 2024; Ord. 2887 § 2 (Exh. A), 2025; Ord. 2911, 3/5/2026)
A. 
For shared parking facilities, parking requirements specified in MTMC § 19.125.120 may be met by adding the number of all such required spaces for each separate function and dividing the total by the appropriate factor from the shared factor matrix in subsection B of this section; provided, that the Director at his sole discretion may determine that any proposed shared parking use has special characteristics that need to be taken into account and, in such cases, shall require a parking study to be submitted for review and shall make a determination whether the shared factor matrix or other information shall be used to determine the amount of required off-street parking spaces for shared or joint use. In so doing, the Director may require more parking spaces than would otherwise be required through use of the shared factor matrix. The Director shall determine which functions, if any, from said matrix are most appropriate to the proposed development or use, taking into account any site-specific factors.
B. 
The shared factor matrix below provides for shared off-street parking based on function, in conjunction with other requirements of this chapter.
Shared Factor Matrix
C. 
The following conditions shall apply to shared vehicle parking provided to meet the minimum number of off-street parking spaces required pursuant to subsection B of this section, the shared parking provisions:
1. 
The building or use shall be located on the same lot as the off-street parking, except as provided pursuant to subsection C.2 of this section.
2. 
Required parking facilities for any building or use shall be allowed on a separate lot subject to all of the following conditions:
a. 
The building or use must be within an 800-foot radius of the parking facilities, but not across an arterial road unless within one block of a signalized intersection.
b. 
The applicant shall present to the Department for recording with the County Auditor or successor agency a properly drawn legal instrument, consistent with the requirements of this chapter, conveying an easement that is forfeitable only upon approval by the Director and that runs with the land to provide for a certain number of parking spaces that shall be available for parking by the applicant or his successors on the site containing the easement. The document must show the location of any alternative site and the number and location of parking spaces being provided on the alternative site, excluding any spaces that are otherwise required for another use pursuant to the provisions of this chapter. The document is subject to review and approval by the City Engineer. The cost of the City's review and recording of said document shall be paid by the applicant.
c. 
If for any reason the parking being provided on the alternative site becomes unavailable, the property owner of the site for which the parking is not available shall provide additional parking elsewhere, consistent with the requirements of this chapter.
3. 
Parking spaces shared in common among more than one business or organization on any site shall not be designated for exclusive use by any individual business or organization, except as one of the following conditions applies: (a) the parking facilities were legally established for multiple owners or tenants prior to April 30, 2008, in association with the use of a building built prior to April 30, 2008; (b) the number of parking spaces provided on the site has not been reduced from any number that would otherwise be required, pursuant to MTMC § 19.125.120, for each individual business or use on the site; or (c) joint parking facilities are provided pursuant to subsection C.2.a of this section.
4. 
In mixed-use development, at least one parking space per dwelling unit must be designated exclusively for residential use and shall not count in the calculation of shared parking spaces pursuant to subsection B of this section. A deviation may be allowed for a structure that contains park and ride facilities, if a parking study demonstrates the adequacy of an alternative ratio acceptable to the City's Traffic Engineer or designee.
5. 
Religious facilities that operate primarily on a Saturday or Sunday may share their parking facilities with other uses that operate primarily on weekdays or a weekend time that is separate from the religious facility's use by at least one hour; provided, that the facility has an adequate amount of parking for its own regular use, including the required spaces for any school or other regular operations of the religious facility. Sharing of parking spaces for such uses is subject to review and approval by the department to ensure an adequate amount of off-street parking is provided pursuant to MTMC § 19.125.120.
6. 
For governmental facilities that include two or more uses with parking needs separated by at least one hour from each other, such as a public assembly area that is primarily used on evenings or weekends and an office area that is primarily used on weekdays, the required parking spaces for the public assembly area and the office area may be entirely shared.

1. 
A maximum of two recreational or utility vehicles are allowed to be located on a residential lot;
2. 
Recreational or utility vehicles shall be parked on an improved surface, except: (a) where an existing maintained surface was constructed prior to July 1, 2006, the recreational or utility vehicle may park on the existing maintained surface; or (b) where a recreational or utility vehicle is legally parked in a rear or side yard, it may be on either an improved surface as defined in this section or an unimproved surface as defined in MTMC § 8.15.030;

Off-street vehicle parking in residential zones is subject to the following standards:
1. 
A minimum of one off-street parking spaces on an improved surface is required to be provided per each dwelling unit. The area included in a garage may satisfy the requirement for providing one of the required off-street parking spaces. If there is no garage to store vehicles, a minimum area of 154 square feet of improved surface shall satisfy this requirement. The requirement for an improved surface shall be enforced in conjunction with property improvements and nonconformance requirements under MTMC § 19.120.250.

3. 
No more than 50 percent of the front yard shall consist of an improved surface to be used for the parking or driving of vehicles. An exception shall be made in cases where because of the lot's configuration, for instance in a cul-de-sac development, the front yard does not have adequate area to simultaneously comply with the minimum parking requirement prescribed under subsection D.1 of this section and the 50 percent limit described above. In such cases, the 50 percent limit may be exceeded subject to the department's issuance of a driveway permit that specifically allows the additional improved surface or maintained surface within the front yard.
4. 
Auxiliary parking spaces and auxiliary driveways must consist of an improved surface, except that any auxiliary parking or auxiliary driveway installed prior to July 1, 2006, may continue to consist of a maintained surface until such time as a new building or a building addition is constructed or permitted for construction on the same lot.

For any use that does not clearly match with a more general function listed in said table or for any specific use that has special characteristics that may require a different amount of parking than would typically be needed by the more general function, as either is determined by the Director, a parking study shall be required; provided, that, as an alternative, the Director may require the development to provide a certain amount of parking spaces for the specific function or use based on nationally accepted standards.
2. 
For purposes of this section, eating/drinking establishments that include other uses, such as gaming or recreation, that are more than incidental, shall have 12 parking spaces per 1,000 square feet of GFA, unless the Director approves a different number based on the findings of a submitted parking study.
3. 
For public assembly areas, the Director may impose a requirement of one parking space for each 50 square feet of GFA, instead of one space for each four seats, or may determine an alternative parking requirement, based on findings of a submitted parking study or nationally accepted standards.
4. 
For office, medical, retail, restaurant, light manufacturing, or similar uses, the applicant may submit a parking study to demonstrate a parking demand that varies from the minimum number of spaces otherwise required by this chapter. Pursuant to subsection B.1 of this section, the Director may approve a different number of parking spaces than otherwise required, based on the findings of the submitted parking study.

The costs of any parking study and the City's review time for the study shall be paid by the applicant.
2. 
Approval of business licenses and certificates of occupancy is subject to verification that the required parking spaces are provided consistent with this chapter or that the Director determines the use will not otherwise create actual parking deficiencies, taking into account all uses on the site. Noncompliance with applicable provisions of this chapter is cause for denial or revocation of the business license or certificate of occupancy.
C. 
Exceptions for Housing for Senior Citizens.
1. 
The requirement of one space per dwelling unit that would normally apply to housing for senior citizens because it is considered an "apartment/multi-household" use, according to subsection A of this section, may be reduced to no less than one space for every three dwelling units as determined by the Planning Commission. The Commission shall base their decision on the following:
a. 
Availability of private, convenient, regular transportation services to meet the needs of the occupant;
