4-4-080 PARKING, LOADING AND DRIVEWAY REGULATIONS:

A. PURPOSE:

It is the purpose of this Section to provide a means of regulating parking to promote the health, safety, morals, general welfare and aesthetics of the City of Renton by specifying the off-street parking and loading requirements for all uses permitted in this Code and to describe design standards and other required improvements. Furthermore, it is the intent of this Section to promote the efficient use of the City’s transportation facilities by incorporation into that system of alternative modes of transportation to the single occupancy vehicle to promote the movement of people from place to place. It is the goal of this Section to allow the provision of sufficient off-street parking to meet the needs of urban development while not providing an excess surplus of spaces. (Ord. 4517, 5-8-1995)

B. SCOPE OF PARKING, LOADING AND DRIVEWAY STANDARDS:

1. Applicability:

a. Within the Center Downtown Zone: This Section, except for subsections F1 through F9 and J of this Section, shall apply in the following cases:

i. New Buildings or Structures: If construction replaces an existing building, only the area exceeding the area of the original structure shall be used to calculate required parking.

ii. Building/Structure Additions: Only the area exceeding the area of the original structure shall be used to calculate required parking.

b. Outside the Center Downtown Zone: Off-street parking, loading areas, and driveways shall be provided in accordance with the provisions of this Section in the following cases:

i. New buildings or structures.

ii. Building/Structure Additions: The enlargement or remodeling of an existing building/structure by more than one-third (1/3) of the area of the building/structure.

iii. Paving or Striping: The paving of a parking lot with permanent surface, or striping a previously unstriped lot.

iv. Change in Use: Upon a change of use and except when located in a shopping center, if the number of stalls needed for the new use exceeds the actual number of legally existing stalls on site by a percentage equal or greater than shown in the table below, all of the stalls required of the new use shall be provided. However, upon a change of use to any of the following uses, the new use shall provide the total number of parking stalls required without the exception described above:

(a) Residential uses;

(b) Offices, general;

(c) Conference centers; and

(d) Movie theaters.

Existing Stalls	Percentage Threshold
1 – 10	140%
11 – 30	130%
31 – 60	120%
61+	110%

For example, if the calculated number of stalls needed for a retail store equals fifteen (15) and only ten (10) stalls legally exist on site, then all fifteen (15) stalls shall be provided because the percentage difference between the number of stalls needed for the new use and the number of existing stalls on site exceeds one hundred forty percent (140%) [1.40 x 10 = 14].

v. Activities Requiring Deliveries or Shipments: Uses requiring merchandise deliveries and/or shipments shall provide adequate permanent off-street loading space in addition to required parking for the use.

vi. Redevelopment Sites in the R-10 and R-14 Zones: When new dwelling units are created in the Residential Ten Dwelling Units per Acre (R-10) and Residential Fourteen Dwelling Units per Acre (R-14) zones, whether by subdivision or other means, any existing dwelling units included in the development shall comply with the standards of this Section.
