17.58.040 Rules for calculating required parking and freight loading areas.
A. In calculating off-street parking and freight loading spaces, the following rules shall apply:
1. Parking computations will be based on the gross floor area of entire buildings and structures unless otherwise stated in this chapter. For buildings and structures being remodeled or to which additional floor area is being added, the parking computations shall also be based on the gross area of the entire building or structure.
2. When after computing the number of parking spaces required for a structure there appears a fractional requirement of one-half or more of a parking space, one additional parking space shall be required. If after such computation the fractional requirement for a given number of spaces is below one-half space, no additional parking will be required for that fractional parking space.
3. Parking for buildings containing three or more stories shall be based on the conditioned or net floor area.
B. The requirements for off-street parking and loading for any use not specifically mentioned shall be the same as for a use specified which is similar, as determined by the planning director.
C. Where a parcel or site contains a use with existing legal nonconforming parking, no additional parking shall be required unless there is a change of use, a new building or use is proposed, or an existing building or use is enlarged. Parking will then be assessed as follows:
1. Building additions will only be required to provide new parking based on the added floor area.
2. If a new use requires less parking than the previous use, no additional parking shall be required.
3. Parking lots or garages with legal non-conforming design standards may remain subject to approval of the planning director and traffic engineer provided such does not compromise traffic circulation or public safety. (Ord. 4521 § 10, 2008)
