All buildings and structures erected or added to and all land uses initiated after the effective date of this chapter shall provide accessory off-street parking or loading facilities as required for the use herein.

When a building or structure erected or enlarged prior to or after the effective date of this chapter shall undergo a decrease in the number of dwelling units, gross floor area, seating capacity, number of employees or other units of measurement specifically set forth hereafter for the required off-street parking or loading facilities, off-street parking and loading facilities may be so decreased only when the facilities remaining would at least equal or exceed all off-street parking or loading requirements resulting from application of the provisions of this article. This includes surfacing requirements.

All parking areas established prior to the effective date of this chapter, but not in conformance with all provisions of this article, are allowed to continue as previously laid out. Any change or alteration to existing parking areas shall require that portion to be altered to be in accordance with all provisions of this article. Accessory off-street parking and loading spaces in existence on the effective date of this chapter may not be reduced in number unless the remaining off-street parking equals or exceeds all provisions of this article for equivalent new construction of the current use and building size.

Any change in use or in size of an existing building that would require a greater number of off-street parking spaces than the previous use or size shall provide additional off-street parking in accordance with this article. If the number of additional required parking spaces results in more than a 25% increase in the total number of parking spaces currently provided on the lot, or requires the addition of at least three more spaces, whichever is greater, then all existing parking is also required to equal or exceed all provisions of this article, including surfacing.

Parking space number requirements for expansion of existing buildings or uses or for an additional structure on a developed lot shall be determined by combining the requirements for all existing uses and all new development using requirements of this chapter.

The number of required parking spaces for mixed uses shall be computed as follows:
