Green Building Requirements

Community Development Agency

New State and local standards regarding green building went into place on January 1, 2020. Please make sure you are referencing the correct standards.

Green Building is a whole systems approach to construction and building operations that minimizes the large impact that our built environment has on our environment. Green building also provides many benefits to the homeowner including long term value, reduced energy and water use, reduced maintenance, and a more comfortable and healthy indoor environment.

For more information on Marin County's Green Building Program or for green building technical assistance on any building project in Marin, contact Brian Reyes, via email or by phone at (415) 473-2797.
