Multifamily Apartment Units

Starting January 2022, all California residents will be required to compost organic waste properly. The law aims to reduce harmful methane emissions from landfills that contribute to climate change and global warming.

Please visit CalRecycle's website and Zero Waste Marin's website for more information on the new law.

I'm a tenant, how will this law affect me?

This new law requires you to compost all organic waste.

Your building's property manager is required to provide the building with a labeled compost bin close to the disposal container to discard organic waste. If your apartment building does not have composting service, please contact your property administrator.

Please remember to pay close attention to what you place in the bin. Not everything labeled compostable can be composted. Need more guidance? Visit the Marin Sanitary Service website and use the “Where does it go, Joe?” tool! Even a small amount of trash in the compost bin means that all the material goes to waste.

I own and or manage a multifamily property; what do I have to do to comply?

The new state law mandates that all multifamily buildings must offer composting service to tenants regardless of size.

  1. Subscribe to curbside compost and recycling collection service in addition to garbage
  2. Place color-coded and labeled compost and recycling containers next to all indoor garbage containers (excluding restrooms)
  3. Sort materials into the proper bins.
  4. Periodically inspect bins and provide feedback to employees and contractors about incorrectly placed items.

If your multifamily apartment building has more than 5 units, you must also:

  1. Educate employees, contractors, tenants, and subtenants about the law annually
  2. Inform tenants no later than 14 days after move-in and at least 14 days prior to move-out about the rules

To subscribe to composting service, contact Marin Sanitary Service at (415) 456-2601, Monday through Friday, from 8:00 a.m. to 5:00 p.m. Please visit Zero Waste Marin's website for more information on requirements for property managers.
