The purpose of this chapter is to provide for regulation of off-street parking within all commercial, industrial, residential and open space districts. In addition, access to parking, parking lot lighting, parking lot landscaping, driveway design, and required aisle widths are also regulated within this chapter.

(Ord. 93-03-1152 § 18 (part): Ord. 88-09-1015 § 1 (part))

   The following general standards shall apply to all districts unless otherwise specified:

   A.   No parking area, parking space or loading space which is provided for the purpose of complying with the provisions of this title shall hereafter be relinquished, reduced or altered in any manner unless equivalent facilities are provided elsewhere, the location of which is approved by the planning commission, and legal access to such equivalent facilities by appropriate recorded instrument has been approved by the city attorney.

   B.   Where automobile parking is provided and maintained on a lot in connection with a main building or structure on or before the effective date of the ordinance codified in this chapter and is insufficient to meet the requirements for the use as provided in this title, or where no such parking has been provided, such automobile parking may be continued as a nonconforming use. Any such building or structure may be altered or enlarged only if parking is provided in conformance with the provisions of this title for the portion of the building or structure altered, added to, enlarged or extended. Existing parking may not be counted toward meeting the required parking for the alteration, addition, enlargement or extension.

   C.   In the case of a legally existing residential use in a residential district, on or before the effective date of the ordinance codified in this chapter where additional dwelling unit(s) are permitted, parking in conformance with this title shall be required only for the new dwelling unit(s)

   D.   All motor vehicles incapable of movement under their own power without alteration or repair shall be stored in an entirely enclosed garage or space enclosed by minimum six-foot solid fence or wall. No inoperable motor vehicle shall be left on public or private property for more than seventy-two hours unless enclosed by a garage, wall or fence. Such regulation shall not apply to automobile related uses such as automobile dealerships, automobile repair shops, automobile body and paint shops which utilize approved outdoor storage areas meeting the requirements of Sections 20.20.020 and 20.30.020 of this code.

   E.   House trailers or campers which are incapable of movement without being attached to another vehicle may only be stored in the rear yard of any residential use, must be owned by the owner or tenant of such property, and must be enclosed within an area bounded by a six-foot height solid fence or wall. Within any commercial or industrial district, house trailers or campers may only be stored within an enclosed building unless the property is specifically authorized to store and/or display such vehicles. Such vehicles may not be used for residential purposes in any district.

   F.   No motor vehicle, house trailer, camper shell, tent trailer, watercraft, or utility trailer, including trailers used to transport boats, motorcycles, automobiles, recreational vehicles, household goods or construction equipment shall be parked in any front yard or side yard unless parked on a driveway. For purposes of subsection, yard shall include not only the required open space area as defined in this code, but also the area between the respective setback line, as defined in this code, and the opposing exterior building wall. Driveway shall be defined as in Section 20.04.243 or as legally constructed and in use prior to the effective dates of Section 20.04.243 of this code provided such driveway is joined with an adjacent alley or street by a city-approved curb cut, ramp, and/or other appropriate transition.
