Construction & Demolition Guidelines
New California Green Building Standards!
California’s Green Building Standards Code (CALGreen) requires the diversion of at least 65 percent of the construction waste generated during most “new construction” projects (CALGreen Sections 4.408 and 5.408). Please see this table to see what the current requirements are. Please remember, this does not represent a complete list of requirements and contact your local building department for more information. For more information on CALGreen, see the following questions.
- Where can I find a copy of the code?
- What are the code’s waste diversion requirements?
- Which types of construction occupancies are covered under CALGreen?
- What changes does the 2019 update make to CALGreen?
- Who is responsible for enforcing CALGreen?
- If building departments of cities and counties are responsible for implementing the updated California Green Building Standards Code, please explain the level of involvement required by recycling coordinators?
- What flexibility does a jurisdiction have when applying CALGreen?
- Does CALGreen apply to both demolition permits, and construction permits?
- What if our local ordinance has a higher diversion requirement than 65 percent?
- Is there is a minimum size project to which the code applies?
- Our C&D diversion ordinance requires recycling on all new construction with a specific cost and/or square footage threshold. Does our jurisdiction still need to implement CALGreen?
- If my jurisdiction does not have an ordinance or policy, then must we still implement CALGreen?
- If the jurisdiction is required to use the 65 percent number, can we implement some sort of review of projects that don’t report 65 percent and grant “good faith effort” compliance for builders who implement a recycling program but just didn’t generate enough recyclable materials to hit the 65 percent?
- Does our jurisdiction have the flexibility to exempt projects such as pool construction or installation of small, prefabricated buildings?
- How does CALGreen apply to residential re-roofs?
- Does CALGreen apply to school or hospital construction projects?
