(a) Except as hereinafter provided, no residential, commercial, industrial or other building or structure shall be erected and no major repairs, substantial alterations or extensions shall be made to an existing residential, commercial, industrial or other building or structure unless off-street parking space is provided in accordance with the provisions of this zoning ordinance in the minimum amounts specified in division (c) below. Where it is proposed to improve an existing building or structure by major repairs, substantial alterations or extensions, or the use of an existing building or structure is changed and the building or structure, together with the adjacent lot area, does not fulfill the parking requirements of division (c) below, the Board of Zoning Appeals may recommend to Council a modification of these requirements, provided the Board determines that the recommended modified requirements will not have a more adverse effect upon the neighborhood than the existing nonconformities and are in harmony with the general intent of this zoning ordinance and will secure the general welfare and substantial justice in the promotion of public health, comfort, convenience, morals, safety and general welfare of the city.
(b) All off-street parking areas shall conform to the following requirements.
(1) With the exception of parking stalls in which vehicles are parked parallel to the parking aisle, the depth of any parking stall measured perpendicularly to the parking aisle shall be not less than 20 feet.

(3) The width of any parking aisle shall be not less than 25 feet.
(4) All parking areas shall be designed so that during a backing maneuver no part of a vehicle shall encroach beyond the limits of the parking area or into a dedicated street or setback.
(5) The Board of Zoning Appeals may require parking stalls in addition to the minimum specified by this zoning ordinance where the parking aisles or other portions of the parking area are to be used for any purpose other than for aisles or parking or when, because of the shape or location of the parking area in relation to any abutting streets or private property, such additional parking stalls are deemed necessary.
(6) In the interests of safety to persons and protection of property, the Board of Zoning Appeals may require that a protecting curb or barrier at least five inches high be placed to prevent any part of a vehicle from extending beyond the limits of the parking stall.
(7) Existing parking areas which are used for existing businesses may not be reduced below the minimum requirements of this zoning ordinance for new businesses unless the character of the existing business is changed to require a lesser parking area. For the purpose of interpreting the parking requirements of this zoning ordinance as relating to new businesses, such existing parking areas for existing businesses may not be used in calculating the available parking spaces required for new businesses.

(1) Dwellings shall have one off-street parking space for each dwelling unit.

If, in addition to those spaces provided for guests, patrons or residents of the above named places, assembly halls, bars, restaurants, night clubs, retail shops or room for other shops, service establishments or businesses are provided, additional off-street parking spaces shall be provided in the amount specified in this zoning ordinance for such uses.

(7) Buildings containing retail establishments, including personal service shops, equipment or repair shops, gasoline filling stations, motor vehicle sales or repair establishments, retail stores and banks or other financial institutions shall have one off-street parking space for each 200 square feet of gross floor area used or intended to be used for service to the public as customers, patrons and clients.

When practical difficulties, in the opinion of the Board of Zoning Appeals, prevent establishment of off-street parking facilities required by this zoning ordinance on such same lot or parcel of land, the Board of Zoning Appeals may, subject to use limitations, approve another location for such facilities if such location is reasonable and consistent with the intent of this zoning ordinance.
(e) No part of an off-street parking area required by this zoning ordinance for any one building or use shall be included as a part of an off-street parking area similarly required for another building or use.
(f) Except where otherwise permitted as a conditional use pursuant to § 1123.03(a)(16) of this zoning ordinance, off-street parking facilities as an accessory use must be located in the same or a less restricted use district as that required for the principal use of the premises.
