§ 9.7.2. Expansion Or Addition

The following guidelines are used in calculating requirements for an expansion or addition:

A.

If the existing use complies with the parking requirements in Chapter 25-6, Appendix A, the expanded facility must also comply with the parking requirements in the table.

B.

If the existing use does not comply with the parking requirements in Chapter 25-6, Appendix A, the expansion or addition is not required to make up the parking deficiency for the current use, but only to provide the additional spaces needed for the expansion or addition. The total number of spaces required for the expanded facility is the number of spaces computed by Chapter 25-6, Appendix A, for the addition or expansion, plus the number of existing spaces for that use.**

For example, assume that an existing restaurant of 2000 square feet has only 15 parking spaces, instead of the 20 that would be required under current regulations (1 space per 100 square feet). If the restaurant adds 400 square feet, the total requirement would be:

Expansion (400 square feet × 1 space/100 square feet)	=	4 spaces
Existing:		+15 spaces
Total Requirement		19 spaces

 

** If there is a site plan or other documentation of the number of parking spaces required at the time the use was originally approved, that number must be used instead of the number of spaces actually provided.

The exception to this rule is a cocktail lounge or late-hours restaurant. Under Section 25-6-471, as amended by Ord. No. 920109-I, a cocktail lounge or late-hours restaurant which expands must comply with the current parking requirement for the entire structure, not only for the expansion.

For example, assume that an existing cocktail lounge of 2000 square feet has only 15 parking spaces, instead of the 20 that would be required under current regulations (1 space per 100 square feet). If the cocktail lunge wishes to add 400 square feet, the total requirement would be: 2400 square feet × 1 space/100 square feet = 24 spaces.

C.

If the existing use complies with the parking requirements in Chapter 25-6, Appendix A, and the addition or expansion would increase the total floor area to a level that would require a higher or lower parking ratio than the existing structure provides, the higher or lower parking ratio is applied to the total structure, not only to the addition or expansion. In this case, the expansion constitutes a "change in the manner of operation" as identified in Section 25-6-471, and the total floor area must be considered in determining the parking requirement.

For example, the parking ratio for restaurants is 1 space per 100 square feet if the floor area is 2500 square feet or less, and 1 space per 75 square feet if the floor area is over 2500 square feet. If an existing restaurant of 2000 square feet provides the 20 spaces required and wishes to add 550 square feet, the parking requirement for the total structure (2550 square feet) would be:

2550 square feet × 1 space/75 square feet = 34 spaces

D.

If the existing use does not comply with the parking requirements in Chapter 25-6, Appendix A, and the addition or expansion would increase the total floor area to a level that would require a higher or lower parking ratio than the existing structure provides, the parking requirement for the expanded facility is computed in a similar manner to the preceding example; however, the existing use is not required to make up the existing deficiency in parking. The existing deficiency would be subtracted from the calculation in order to determine the total number of spaces required.

For example, if an existing restaurant of 2000 square feet provides only 15 spaces, instead of the 20 required by current regulations, and wishes to add 550 square feet, the parking requirement would be:

2550 square feet × 1 space/75 square feet	=	34 spaces
Existing deficiency		- 5 spaces
Parking requirement		29 spaces

 

The exception to this rule is a cocktail lounge or late-hours restaurant. Under Section 25-6-471, as amended by Ord. No. 920109-I, a cocktail lounge or late-hours restaurant which expands must comply with the current parking requirement for the entire structure, not only for the expansion. In the example cited above, if the facility were a cocktail lounge instead of a restaurant, the parking requirement would be: 2550 square feet × 1 space/75 square feet = 34 spaces.
