The bill introduces a new section to chapter 36.70A RCW, establishing regulations for parking configurations in residential developments. Key provisions include the elimination of requirements for garages and carports to meet minimum parking standards, allowing both enclosed and unenclosed parking spaces to count towards these requirements. It also specifies that tandem parking spaces can be counted at a rate of one space for every 20 linear feet, and existing gravel surfacing in designated parking areas cannot be used to prohibit the utilization of those spaces, up to a maximum of six. Additionally, the bill states that parking spaces do not need to exceed eight feet in width, with exceptions for accessible parking, and allows for grass block pavers to count towards minimum parking requirements.

Furthermore, the bill stipulates that existing nonconforming parking spaces are not required to be modified unless necessary for compliance with the Americans with Disabilities Act. It also provides that existing paved parking lots do not need to change the size of parking spaces during resurfacing if it would be cost-prohibitive or require significant reconfiguration. Notably, these provisions do not apply to areas within a one-mile radius of commercial airports with high annual enplanements.
