Compliance forms for low carbon concrete

All building project applicants, contractors, and concrete suppliers are required to comply with Marin County's low carbon concrete code (Title 19 Marin County Building Code, Chapter 19.07 - Carbon Concrete Requirements). 

The easiest way to comply is to use products from our list of pre-qualified mixes, available from local ready-mix suppliers.

Compliance forms must be submitted by design professionals as a part of plan review, and again by contractors at time of final inspection. Choose the correct compliance form based on your role below.
