As much as 30% of the waste that goes to landfills is construction and demolition (C&D) debris. Most of this material is recyclable, including asphalt, concrete, wood, metal, and cardboard. Recycling this material conserves natural resources and saves valuable landfill space.

In compliance with the California Green Building Standards Code* (CalGreen), and the City's Construction & Demolition Debris Recycling Ordinance (No. 1639-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 Debris Recovery Plan for approval before receiving a permit and a Final Report at the time of Final Inspection of their project.

What Projects Must Comply with CalGREEN Building Standards Code*?

• All new construction of permitted structures 
• All demolition of permitted structures 
• Additions and alterations to residential buildings that require a permit.

• All new construction of permitted structures 
• All demolition of permitted structures 
• Permitted additions or alterations of 1,000 SF or more, and/or with a valuation of $200,000 or more (Tenant Improvements).

C&D Recycling FAQ

How much does this cost? 

$0. Many jurisdictions require a bond for 3% of the construction cost. Some also have monthly fees assessed until the final report is turned in and approved. The City of Thousand Oaks, to minimize the costs to our businesses and residents, has chosen to not impose a fee for submitting your C&D Debris Recovery Plan at this time. In the event that we do not receive the final reports, we will reassess placing a bond requirement on projects. We will also be maintaining a list of non-compliant contractors which may be made available to the public on our website at some point in the future.

Why do I have to complete this requirement? 

It is State & Local law. As much as 30% of the waste that goes to landfills is C&D debris that can be reused or recycled. The Construction & Demolition Debris Recycling Ordinance (No. 1639-NS) requires that certain demolition and/or construction projects divert at least 65% of project-generated waste through recycling or reuse.

Which waste disposal facilities am I required to use?

Contractors and waste haulers are not restricted in their disposal options for C&D debris, as long as projects meet the City's 65% debris diversion requirements.

Projects that utilize mixed waste recycling will require that materials are processed at a mixed C&D processing facility. The nearest mixed C&D processing facility is located approximately 10 miles north-east 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 utilizing any of these certified facilities must use the listed Mixed C&D Debris Recycling Rate in determining their diversion rate on the C&D Recycling Plan and the C&D Recycling Report.

Who can haul construction & demolition waste in Thousand Oaks?

In order to uphold high levels of service, maintain consistent reporting methods and ensure compliance and good business practices, the City utilizes a Limited Franchise system for temporary waste collection. Currently there are four Limited Franchise haulers who are authorized to provide temporary waste collection service in Thousand Oaks.

Additionally, property owners or construction contractors may self-haul debris using their own vehicles.

Visit the Construction, Demolition and Temporary Waste Services Page for more information about authorized haulers and waste disposal facilities.
