18.105.030 General regulations and standards.
A. Location. All required parking and loading spaces and maneuvering areas shall be located on the lot upon which the use served is located. Parking spaces may also be located upon a contiguous lot, within the same zoning district, given the number of required parking spaces are met for both sites, and a city enforceable “off-site parking agreement” is provided in accordance with MCC 18.105.070(C)(3). Parking spaces and maneuvering areas shall not be located within any RS District or in any required front or street side yard or landscaped area in any zoning district, except driveways that directly and immediately allow a vehicle to access the site from a street or abutting property. All vehicles shall enter the public rights-of-way in a forward motion except within the RS Districts when driveway access to local streets or private roadways is permitted for individual lots.
B. Standards. The following standards apply to required on-site parking and loading spaces, maneuvering areas, and access:
1. Required parking and loading spaces, maneuvering areas, and driveways shall be paved with asphalt, concrete, paving stone, or masonry to a sufficient thickness to withstand repeated vehicular traffic. The zoning administrator, in collaboration with the city engineer, may establish alternative standards for porous surface paving.
2. Required parking spaces shall be permanently marked and shall be accessible from a street or alley by a driveway or aisle such that all vehicles shall approach the street or alley in forward motion, except for single-unit dwellings and agricultural uses.
C. Compact Parking. On a site with at least 10 required parking spaces, up to 20 percent of the total required parking spaces may be compact spaces; provided, that the following standards are met:
1. Where covered parking is required all covered parking spaces shall be standard size;
2. All compact spaces are to be designated with a sign or pavement marking; and
3. Compact spaces shall be distributed throughout the parking area, with no more than eight compact spaces in a single row. No more than four compact parking spaces placed end-to-end shall make up any cluster of 10 parking spaces.
D. Accessible Parking. Accessible parking spaces shall be provided and maintained pursuant to the federal Americans with Disabilities Act and Arizonans with Disabilities Act of 1992.
E. Structured Parking. The exterior elevations of any multi-level parking structure must be designed so as to screen or conceal parked cars from view from public streets and open space on the first and second floors of the structure. The floors of structured parking garages must be screened or concealed by one or more of the following methods:
1. Ground-Floor Commercial. The garage’s ground-level street frontage (except for driveways and pedestrian entrances) for the designated front of the structure shall be improved with general retail sales, food and beverage sales, eating and drinking establishments, personal services, or similar pedestrian-oriented uses.
2. Landscaping. Landscaping shall be provided in the form of perimeter planters within openings, and/or the incorporation of hanging baskets, flower boxes, planting trellises, or desert plants.
3. Setback. A parking structure that does not incorporate ground-floor retail or other commercial use or is not otherwise screened or concealed at street frontages on the first and second levels must provide a densely planted landscaped yard that is a minimum of 10 feet in depth, or the required setback for the district in which it is located, whichever is greater.
4. Combination of Opaque Screen Walls and Open Decorative Panels. A combination of opaque screening devices and decorative panels may be used to screen parking within aboveground structures. Opaque screen walls shall not be higher than three feet six inches relative to the abutting floor height, and shall not exceed 45 percent of the aggregate surface area of the exterior wall. Decorative panels or other devices with opacity of at least 40 percent shall be used to screen the remainder. The decorative panels shall be constructed of durable materials, such as iron, steel, copper, aluminum, formed concrete, glass block, brick or other textured masonry.
F. Recreational Vehicle (RV) Parking. A single recreational vehicle may only be parked or stored on property within a residential district as follows:
1. In a driveway, exterior, or interior side yard, or the rear yard for the purpose of loading or unloading or repairs or maintenance, not to exceed 24 hours before or after a trip; or
2. In a driveway, exterior, or interior side yard, or the rear yard, if at least 10 feet from the rear property line and screened so as not to be visible from the street; or
3. In a garage or accessory structure; and
4. The vehicle does not block access to a sidewalk or driveway.
G. Size of Parking Spaces and Maneuvering Aisles. Parking spaces and maneuvering aisles shall be provided to meet the minimum dimensions required by this subsection. Screening walls, roof support posts, columns, or other structural members shall not encroach the minimum required dimensions for parking spaces. A paved space may be reduced by two feet for vehicle overhang if it abuts the landscape median.
1. Standard Parking Spaces. The minimum basic dimension for standard parking spaces is nine feet by 18 feet. Table 18.105.030.G.1 shows the dimensions of a stall and aisle according to the angle of parking spaces.

H. Size of Parking Spaces for Loading Vehicles. Each on-site loading space required by this chapter shall not be less than 12 feet wide, 45 feet long, and 14 feet high, exclusive of driveways for ingress and egress, maneuvering areas and setbacks. The minimum size requirement may be modified if the zoning administrator finds that the applicant has satisfactorily demonstrated that, due to the nature of the proposed use, such size will not be needed. Space shall be signed for exclusive use for loading vehicle.
1. Required loading spaces:
a. Nonresidential Uses. One loading space for 15,000 – 50,000 square feet of building; two spaces if over 50,000 square feet of building.
b. Residential Uses. One loading space if 50 or more dwelling units on site.
I. Size of Parking Spaces for Motorcycles, Scooters, and Golf Carts. Motorcycle and scooter parking spaces shall have a minimum dimension of five feet by nine feet. Golf cart parking spaces shall have a minimum dimension of five feet by 10 feet. All motorcycle and scooter parking areas shall be clearly marked and dedicated to these vehicles.
J. Electric Vehicle Charging Stations. In parking facilities containing 20 or more spaces serving multiple-unit dwellings, offices, hotels, and motels, and large-scale resorts, at least five percent of parking spaces shall be electric vehicle (EV) charging stations. For all other uses, EV charging stations are eligible for sustainable development incentives under Chapter 18.125 MCC.

2. EV charging stations may be equipped with card readers, controls, connector devices, and other equipment as necessary for public use. [Res. 21-09; Ord. 21-05 § 2; Res. 14-36 § 407.03; Ord. 14-12 § 1.]
