CALGreen Diversion Requirements

Every three years the California Building Standards Commission adopts new and/or updated model codes. Effective January 1, 2014, CALGreen mandates permitted new residential and non-residential building construction, demolition and certain additions and alteration projects to recycle and/or salvage for reuse a minimum 50 percent of the nonhazardous construction and demolition (C&D) debris generated during the project (CALGreen sections 4.408, 5.408, 301.1.1 and 301.3). New construction and demolition projects with a combined disposal weight of less than 4 lbs/ft2 in low rise (3 stories or less) new residential structures and 2 lbs/ft2 in non-residential and high rise (4 stories or more) residential buildings meet the 50 percent minimum diversion requirement.

 

Additions to non-residential buildings or structures of at least 1,000 square feet or alterations with an estimated construction cost of at least $200,000 shall divert from landfills at least 50 percent of nonhazardous C&D materials. Additions and alterations to residential buildings that increase the structure's conditioned area, volume or size are also required to meet the 50 percent minimum diversion requirement.

 

Enforcing agencies can require contractors to develop and maintain a waste management plan and/or utilize a waste management company that certifies a minimum 50 percent waste diversion.
