   (a)   Applicability
   The regulations of this chapter apply to all parking areas in all districts established by this title.
   (b)   Parking Required
   Off-street parking, loading and bicycle facilities shall be provided for any new building constructed and for any new use established, for any addition or enlargement of an existing building or use, and for any change in the occupancy of any building or the manner in which any use is conducted that would result in additional spaces being required, subject to the provisions of this chapter.
   (c)   Non-Conformance Due to Parking Requirements
   No use of land lawfully existing on July 20, 1978 is nonconforming solely because of the lack of off-street parking, loading, or bicycle facilities prescribed in this chapter; provided, that facilities being used for off-street parking on July 20, 1978, shall not be reduced in capacity to less than the number of spaces prescribed in this chapter or altered in design or function to less than the minimum standards prescribed in this chapter except for the allowed reductions in parking and the modifications to existing facilities allowed pursuant to Sections 18.52.045 and 18.52.050.
   (d)   Additions or Changes of Use
   For additions or enlargements of any existing building or use, or any change of occupancy or manner of operation that would increase the number of parking, loading or bicycle spaces required, the additional parking shall be required only for such addition, enlargement, or change and not for the entire building or use.
   (e)   Parking Spaces Exclusive
   Parking, loading or bicycle spaces required by this chapter for any building or use shall not be considered to meet the requirement for any other building or use, except where a joint facility serving more than one building or use contains the total number of spaces required for each building or use separately, or where adjusted parking requirements for joint use parking facilities are specifically authorized pursuant to Section 18.52.050.
   (f)   Design of Parking Spaces
   Parking, loading or bicycle facilities required by this chapter, or provided optionally in addition to the minimum requirements prescribed by this chapter, shall conform to the design standards set forth in Chapter 18.54.

   (h)   Parking Provided in Excess of Requirement
   No use shall be required to provide more spaces than prescribed by this chapter, or prescribed by the director in accord with this chapter, or prescribed by any conditional use permit, variance, or planned community district. Where additional spaces are provided, such spaces may be considered as meeting the requirements for another use, subject to Sections 18.52.050 and 18.52.080.
