Latest version.

The 2016 California Green Building Standards Code ("CGBSC") is amended by the changes, additions, and deletions set forth in this chapter and Division 72. Section numbers used below are those of the 2016 California Green Building Standards Code.

(a)

Section 301.1.1 (Additions and alterations) of CGBSC Chapter 3 (Green Building) is amended to read:

Section 301.1.1 Additions and alterations. The mandatory provisions of Chapter 4 shall apply to additions or alterations of existing residential buildings where the addition or alteration increases the building's conditioned area, volume, or size. The requirements shall apply only to and/or within the specific area of the addition or alteration.

The mandatory provisions of Section 4.408 shall apply to the following types of construction or demolition projects for existing residential buildings:

Projects that increase the total combined conditioned and unconditioned building area by 5,000 square feet or more.

Alterations to existing structures impacting 5,000 square feet or more of total combined conditioned and unconditioned building area.

Demolition projects when a demolition permit is required.

Exception: Demolition projects undertaken because the enforcing agency has determined that the demolition is necessary to abate a public nuisance or otherwise protect public health and safety.

For the purposes of determining whether a project meets the 5,000 square-foot threshold, the enforcing agency may deem all phases of a project and all related projects taking place on a single or adjoining parcel(s) as a single project.

Note: On and after January 1, 2014, residential buildings undergoing permitted alterations, additions or improvements shall replace noncompliant plumbing fixtures with water-conserving plumbing fixtures. Plumbing fixture replacement is required prior to issuance of final completion, certificate of occupancy or final permit approval by the local building department. See Civil Code Section 1101.1, et seq., for the definition of a noncompliant plumbing fixture, types of residential buildings affected and other important enactment dates.

(b)

Section 301.3.2 (Waste diversion) of CGBSC Chapter 3 (Green Building) is amended to read:

(c)

Section 4.106.4.2 (New multifamily dwellings) of CGBSC Chapter 4 (Residential Mandatory Measures) is amended to read:

Section 4.106.4.2 New multifamily dwellings. For any new multifamily dwelling other than a dwelling type specified in Section 4.106.4.1, at least five percent of the total number of parking spaces provided for all types of parking facilities, but in no case no less than one parking space, shall be electric vehicle charging spaces (EV spaces). Each EV space shall be equipped with fully operational electric vehicle supply equipment (EVSE). The location of each EV space shall be identified on construction documents. Calculations to determine the number of EV spaces shall be rounded up to the nearest whole number.

(d)

Section 4.408.1 (Construction waste management) of CGBSC Chapter 4 (Residential Mandatory Measures) is amended to read:

Section 4.408.1 Construction waste management. Recycle and/or salvage for reuse a minimum of 65 percent of the nonhazardous construction and demolition waste in accordance with Section 4.408.2.

Exceptions:

Excavated soil and land-clearing debris.

The enforcing agency may identify alternate waste reduction requirements if the agency determines that an owner or contractor has adequately demonstrated that diversion or recycling facilities necessary for the owner to comply with this section do not exist or are not located within a reasonable distance from the jobsite.

(e)

Section 4.408.2 (Construction waste management plan) of CGBSC Chapter 4 (Residential Mandatory Measures) is amended to read:

Section 4.408.2 Construction waste management plan. Submit a construction waste management plan for the project, signed by the owner, in conformance with Items 1 through 5 prior to issuance of building permit. The construction waste management plan shall be updated as necessary upon approval by the enforcing agency and shall be available during construction for examination by the enforcing agency. The plan must do all of the following:

Identify the construction and demolition waste materials to be diverted from disposal by recycling, reuse on the project, or salvage for future use or sale.

Specify if construction and demolition waste materials will be sorted on-site (source-separated) or bulk mixed (single stream).

Identify diversion and disposal facilities where the construction and demolition waste material will be taken and identify the waste management companies, if any, that will be utilized to haul the construction and demolition waste material. A waste management company utilized to haul construction and demolition waste material must have all applicable County approvals.

Identify construction methods employed to reduce the amount of construction and demolition waste generated.

Specify that the amount of construction and demolition debris shall be calculated consistent with the enforcing agency's requirements for the weighing of debris. The owner shall make reasonable efforts to ensure that all construction and demolition debris diverted or disposed are measured and recorded using the most accurate method of measurement available. To the extent practicable, all construction and demolition debris shall be weighed using scales. Scales shall be in compliance with all regulatory requirements for accuracy and maintenance. For construction and demolition debris for which weighing is not practical due to small size or other considerations, a volumetric measurement shall be used. The owner shall convert volumetric measurements to weight using the standardized conversion factors approved by the enforcing agency for this purpose.
