18.105.010 General off-street parking regulations.

In all zoning districts, off-street parking facilities shall be provided in an amount not less than that hereinafter specified, for the parking of self-propelled motor vehicles, for the use of occupants, employees, patrons, members and clients of buildings and uses erected or established after the effective date of these regulations, and of existing buildings and uses which are extended, enlarged or changed thereafter.

Buildings and uses in existence at the effective date of these regulations shall be exempt from parking requirements hereinafter specified; provided, however, that whenever the usable floor area of such an existing building is changed, or an existing use of premises is extended, off-street parking for the increased floor area or use shall be provided in the minimum amount hereinafter specified for that kind of use.

The owner or occupant of any building or use subject to off-street parking requirements under these regulations shall not discontinue or reduce any existing required parking lot without first having established other parking space in replacement therefor, which replacement space meets all requirements of these regulations.

The use of off-street parking space as required under these regulations, for the storage of merchandise, vehicles for sale or rent, or repair of vehicles, shall be expressly prohibited. (Ord. 06-10, 2006; prior code § 17-22-1)

18.105.020 Computation of off-street parking requirements.

When a principal building or use includes several different types of activities which generate different levels of parking need, according to the schedule set forth in this section, the minimum required number of off-street parking spaces shall be the sum of individual requirements for the several uses computed separately.

When used in computation of off-street parking requirements, the term “employees” shall include proprietors and administrative personnel as well as all other personnel engaged on the premises in the use of a building, structure, or lot. The “number” of employees shall be the greatest number on duty on the premises at any one time, day or night.

When computation of parking requirements results in a fractional requirement, any fraction of one-half or less shall be disregarded, and any fraction over one-half shall be counted as one space. (Ord. 06-10, 2006; prior code § 17-22-2)

18.105.030 Measurements of off-street parking space.

Every required off-street parking space, except as hereinafter provided, shall have a minimum width of nine feet and a length of 20 feet, exclusive of access drives and aisles. When used as a unit of measurement of unmarked parking lots, each required space shall constitute an area of not less than 280 square feet which shall include drives and aisles.

Since two-wheel and three-wheel motor vehicles are becoming an accepted part of the transportation scene, provision is hereby made for determining the size and number of spaces allocated to this type vehicle in any parking lot. The size of a space for parking a two- or three-wheel motorcycle shall be one-half the size of that required herein for a conventional four-wheel vehicle, that is 140 square feet per space in an unmarked parking lot. In parking lots with marked spaces, the size of the space shall be no less than four and one-half feet wide and 20 feet in length, provided these spaces are aligned in the same row with spaces of four-wheel vehicles. If the parking spaces for motorcycles are separated from those allocated to four-wheel vehicles or not in the same line, the size of the motorcycle space shall be not less than four and one-half feet in width and 10 feet in length. In either case, the number of motorcycle spaces shall be counted in the total number of spaces required for an authorized use; provided, that not more than five percent of the total number of spaces are allocated to motorcycles. (Ord. 06-10, 2006; prior code § 17-22-3)

18.105.040 Location of required off-street parking.

A. For Residential Uses. Required off-street parking shall be located on the same lot or parcel as the use it is intended to service; provided, however, that parking for cooperative or condominium-type multi-family residence may be provided in a parking lot not farther than 200 feet from the entrance to each dwelling unit it is intended to service.

B. For Nonresidential Uses. Required off-street parking shall be located within 300 feet of the building or use it is intended to service, the distance being measured from the nearest point of the building or use to the nearest point of the parking lot; provided, however, that parking facilities for a stadium, auditorium, outdoor sports arena, or similar use may be located not farther than 1,300 feet from the nearest point of such building or use. (Ord. 06-10, 2006; prior code § 17-22-4)

18.105.050 Methods of providing required off-street parking.

Required off-street parking may be provided by any one or combination of the following methods:

A. By providing the required parking space on the same lot as the building or use being serviced.

B. By the collective provisions of required parking for two or more buildings or uses whereupon the total of such parking shall be not less than the sum of the requirements for the several buildings or uses computed separately; provided, however, that if two or more of such buildings or uses have operating hours which do not overlap, the board may grant a reduction of individual and collective requirements based upon the special circumstances involved. A written contract for joint use of such facilities shall be executed between the parties concerned and copy filed with the zoning inspector.

C. By securing the consent to use off-street parking facilities under another ownership which is not otherwise used during the principal operating hours of the building or use in question; provided, however, that consent shall be in written form and a copy filed with the zoning inspector. (Ord. 06-10, 2006; prior code § 17-22-5)

18.105.060 Schedule of required off-street parking.

18.105.070 Parking lot placement regulations.

A. Setback from a Street. Where a parking lot abuts a residential district across a street, a three-foot opaque obstruction to the lights from the parking automobiles must be provided between the parking lot and the street line. This may be by the use of a masonry wall or earth berm or depressed grade or any other method that achieves the same purpose. Where a parking lot abuts a residential district on the same side of a street and in the same block, no part of the parking lot shall be closer to the street line than the minimum required front setback for residential properties in the same block. Regardless of the district in which it is located, every part of a parking lot shall be set back from every lot line a sufficient distance to ensure that no part of any parked vehicle will project over any lot line.

B. Setback from an Interior Lot Line. Where a parking lot abuts a residential district along its interior side lot line, and is not separated therefrom by an alley, no part of the parking lot shall be closer than three feet to said lot line.

C. Rear Setback. Where a parking lot abuts a residential district along its rear lot line and is not separated therefrom by an alley, no part of the parking lot shall be closer than three feet to said lot line. Where the rear lot line is contiguous to an alley, no setback is required.

D. Access to Parking from an Alley. Any parking lot may use an abutting alley for direct access to parking spaces; provided, that the full width of the alley is dedicated to the public and fully improved with a hard, all-weather, dust-free surface, properly drained to prevent impoundment of surface water.

E. Access to Parking from a Street. Access to a parking lot from a street shall be limited to driveways and there shall be no direct access to any off-street parking space from a street.

F. Ingress and Egress. No entrance or exit to a parking lot shall be located closer to an abutting residential district than 15 feet.

G. Lanes and Aisles. Lanes and aisles in parking lots shall be as follows:

1. Between two rows of parking spaces oriented perpendicular to the lane or aisle, the minimum width of the lane or aisle shall be 24 feet.

2. Between two rows of angled parking, the minimum width of the lane or aisle shall be 20 feet.

3. Between one row of perpendicular parking and one row of angled parking, the minimum width of the lane or aisle shall be 20 feet.

4. Between one row of perpendicular parking and a curb, building, or other structure, the minimum width of the lane or aisle shall be 20 feet.

5. Between one row of angled parking and a curb, building or other structure, the width of the lane or aisle shall be 20 feet.

H. Required Improvements and Maintenance.

1. Surfacing.

a. All required primary parking lots for new developments shall be hard surface, paved with asphalt or concrete materials and must meet all ADA parking requirements. Secondary paved areas (such as overflow parking lots, on-site sidewalks, patios) can use alternate materials such as asphalt chip seal or decomposed granite upon approval from the building official.

b. Existing parking lots are permitted to retain their present surfacing, provided no remodeling occurs that changes the exterior character of the building, there is no change of use, or there is no new business license required for the property. If any of these changes occur, then the property is subject to ADA parking lot requirements. This would require the installation of hard surface for the ADA portion of the parking lots. The remainder of the parking lot surface may remain; provided, that it is in good condition. If maintenance is required, it can be maintained with present materials; however, if replacement is required, it must conform to the requirements for subsection (H)(1)(a) of this section. If a request is made to pave a previously existing unpaved parking lot, it must conform to the requirements for subsection (H)(1)(a) of this section.

c. Every parking lot shall be subject to approval by the building official.

d. Existing parking lots using chip and seal materials may be granted an annual exception by the building official; provided, that the lot is stabilized and maintained to acceptable standards so that neither a hazard nor a nuisance is created, and the existing parking lot meets all applicable regulations and standards for accessibility established by the ADA. If a hazard or nuisance is noted by the building official, the parking lot shall be required to be repaired to acceptable standards or replaced to conform to requirements for subsection (H)(1)(a) of this section.

2. Drainage. All parking lots must be graded in such a manner as to allow for property drainage and to prevent the impoundment of surface water.

3. Screening. Where the interior side lot line or rear lot line of a parking lot, located in business or industrial districts, abuts a residential district and is not separated therefrom by an alley, a solid, unpierced, masonry screen wall not less than six feet in height above grade shall be erected abutting the lot line; provided, however, that in no case shall a screen wall extend closer to a street line than the minimum required setback for residential properties on the same block.

4. Landscaping. The area between the street line and the parking lot shall be suitably landscaped and maintained by the owner or operator of the parking lot.

5. Lighting. Parking lots used during hours of darkness shall be lighted. The overall height of lighting fixtures shall not exceed 27 feet above the grade, including base, and fixtures shall be so constructed and arranged to reflect light away from any adjacent residential district. Lighting less than 13 feet and six inches shall be protected against vehicular and pedestrian traffic. (Ord. 16-15 § 1, 2016; Ord. 06-10, 2006; prior code § 17-22-7)

18.105.080 Off-street loading requirements.

In all zoning districts, for every building or part thereof, erected or enlarged after the effective date of these regulations, which is occupied or to be occupied by a manufacturing plant, storage warehouse, wholesale establishment, retail establishment, freight terminal, hospital, laundry, dry cleaning, mortuary, or similar use requiring receipt or distribution of materials or merchandise by motor truck, there shall be provided and maintained, on the same premises as the building or use, adequate off-street loading space meeting the minimum requirements hereinafter specified. Loading space as hereinafter required shall not be considered as satisfying requirements for off-street parking space.

A. Schedule of Loading Space Requirements.

Total Floor Area
of Building

Number of Loading Spaces Required

1,000 – 10,000 square feet


10,000 – 30,000 square feet


30,000 – 50,000 square feet


For each additional 100,000 square feet

1 additional

B. Location of Loading Space. Required off-street loading space may occupy all or any part of a required rear yard, except as provided elsewhere in these regulations, and may be partially or entirely enclosed within a building. Where a side yard abuts an alley in a nonresidential district, loading space may be located in that side yard.

C. Use of Alley for Maneuvering Space. Where a building or use in a nonresidential district requiring off-street loading space abuts an alley, such alley may be used for maneuvering space for loading and unloading spaces; providing, however, that no alley abutting any residential district may be so used.

D. Measurement of Loading Space. Every required off-street loading space shall have a minimum width of 12 feet, a minimum length of 45 feet and a minimum height of 14 feet, exclusive of access aisles and maneuvering space. (Ord. 06-10, 2006; prior code § 17-22-8)

18.105.090 Plans required for off-street parking and loading spaces.

Plans shall be submitted to and approved by the zoning inspector showing how the required parking and loading spaces are to be arranged in the area provided for the purpose. Such plans shall show access streets, alleys and drives, location of all points of ingress and egress, parking spaces, loading spaces, aisles and maneuvering space, and location and design of all screen walls, landscaping and lighting. Before issuance of a zoning compliance certificate, the zoning inspector may obtain the approval of the public works director. (Ord. 06-10, 2006; prior code § 17-22-9)
