• Unincorporated Marin’s Low Carbon Concrete Code to be Enforced

    An Announcement for Design Professionals and Contractors Pouring Concrete

    The County of Marin is now stepping up enforcement of its Low Carbon Concrete Ordinance adopted in 2019.  Due to the economic uncertainty of the pandemic, the County decided to defer enforcement until January 1, 2023. 

    This is an announcement encouraging all design professionals (e.g., engineers, architects), contractors pouring concrete, and approved 3rd party plan reviewers/inspectors to ensure compliance so your project does not experience any further delays. 

    Visit the Low Carbon Concrete Requirements landing page for details on code requirements, compliance forms, best practice on specifying compliant mixes, and ready mix-suppliers looking to pre-qualify mix designs.
