CalGreen / Construction & Demolition (C&D) Debris Recovery Program

Program Overview

The 2019 California Green Building Standards Code (CalGreen) (PDF), as amended in Contra Costa County Code, requires that at least 65% by weight of job site debris generated by most types of building project types be recycled, reused, or otherwise diverted from landfill disposal. This requirement applies to demolition projects and most new construction, as well as the majority of building additions or alterations (see CalGreen Project Type Guide (PDF) for more details). CalGreen requires submission of plans and reports with verifiable post-project documentation to demonstrate that at least 65% of the nonhazardous construction and demolition (C&D) debris generated on the job site are salvaged for reuse, recycled or otherwise diverted.

A Guide to the CalGreen Review Process 

  1. Email completed CalGreen Plan (Residential (PDF) or Non-Residential (PDF)) to your assigned Plan Checker for approval. 
  2. If your Plan is approved, Plan Checker will remove the "Hold permit issuance for CalGreen Plan" on your permit. 
  3. Once your building permit issued and project construction has been completed, bring project waste to a facility on our Approved List.
  4. Ask for recycling receipts with weights before unloading waste at an approved facility. Receipts that say MSW, MT, Trash, Refuse or General Debris will receive 0% diversion. 
  5. Email receipts and completed CalGreen Report (PDF) to [email protected] for compliance review. If your report is approved, Staff will remove the "120" CalGreen hold on final inspection.
