The California Green Building Standards Code, 2016 Edition, Section 4.305, Water Reuse Systems is amended as follows:

1. Laundry-to-Landscape Infrastructure: Any new one-family dwelling shall install a three-way diverter valve at the drain line of all laundry fixtures intended for optional installation of a laundry-to-landscape irrigation system.

a. Note: A complete laundry to landscape irrigation system shall comply with the California Plumbing Code Section 1502.1.1, Clothes Washer System.

The California Green Building Standards Code, 2016 Edition, Section 4.106.4.2, Electric vehicle (EV) charging space requirements for new multifamily dwellings is amended to include: (a) standards for new multifamily dwellings containing three to 16 units, and (b) increased standards for new multifamily dwellings containing 17 or more units as follows:

(a) New multifamily dwellings containing three to 16 units: Where between three to 16 multifamily dwelling units are constructed on a building site, at least one space shall be an electric vehicle charging space (EV space) capable of supporting future electric vehicle supply equipment (EVSE).

(b) New multifamily dwellings containing 17 or more units: Where 17 or more multifamily dwelling units are constructed on a building site, 10 percent of the total number of parking spaces provided for all types of parking facilities, but in no case less than one, shall be electric vehicle charging spaces (EV spaces) capable of supporting future EVSE. Calculations for the required number of EV spaces shall be rounded up to the nearest whole number.

Note: Projects shall reference the California Green Building Code Section 4.106.4 and California Electrical Code, 2016 Edition, Article 625 for definitions and requirements for electric vehicle charging spaces.

The California Green Building Standards Code, 2016 Edition, Section 5.106.5.3.3 EV charging space calculation is amended to include the nonresidential/commercial voluntary Tier 2 Measure for EV charging space calculation per Section A5.106.5.3.3 as follows:

(a) New Nonresidential Construction. Table A5.106.5.3.2 shall be used to determine if single or multiple charging space requirements apply for future installation of electric vehicle supply equipment (EVSE).

(a) Exemption. If an applicant for a covered project believes that circumstances exist that make it infeasible to meet the requirements of this chapter, the applicant may request an exemption as set forth in Section 23.06.015 of the Municipal Code. In applying for the exemption, the burden is on the applicant to show infeasibility. The following conditions may be considered to determine infeasibility:

(1) Where there is insufficient electrical supply.

(2) Where there is evidence suitable to the local enforcing agency substantiating that additional local utility infrastructure design requirements, directly related to the implementation of these requirements, may adversely impact the construction cost of the project.
