In compliance with the California Green Building Standards Code (CalGreen), and the City's Demolition Debris Recycling Ordinance (No. 1688-NS), construction and/or demolition projects that meet the thresholds outlined below are required to divert a minimum of 65 percent of construction and demolition (C&D) waste from landfill disposal through recycling or reuse. In order to ensure that all projects in the City are compliant, building permit applicants must submit a Construction Waste Management Plan for review and approval, and pay the review fee (as outlined in the fee schedule below), before receiving a permit. Upon completion of the project, the applicant must submit weight tickets verifying the diversion of the waste materials in order to receive sign-off at the time of Final Inspection. Failure to comply with the minimum diversion and weight ticket submittal requirements will result in penalties.

2. All demolition of permitted structures 
3. Additions and alterations to residential buildings that require a permit.

Non-Residential:

While the City does not require contractors and waste haulers to dispose of C&D debris at specific facilities, the contractor or property owner is responsible for ensuring that their project meets the City's 65% debris diversion requirement. Contractors and property owners should research and choose disposal facilities or practices that meet this requirement. 

Projects that generate mixed waste debris should dispose of the materials at a mixed C&D processing facility that attains and verifies at least 65% diversion. The nearest mixed C&D processing facility is located approximately 10 miles northeast of Thousand Oaks at the Simi Valley Landfill.

Additionally, the City of Thousand Oaks currently accepts material processing at facilities certified by the Los Angeles Bureau of Sanitation. Contractors using any of these certified facilities must use the listed Mixed C&D Debris Recycling Rate to determine their diversion rate on the C&D Recycling Plan and the C&D Recycling Report.
