Marin’s updated county code was voted on in September, 2019. It offers 3 updated compliance pathways: one for all electric construction, one for limited mixed fuel (gas stoves) construction, and mixed fuel construction. The mixed fuel pathway requires the most strict compliance with Cal Green Tier 1 and electrification readiness requirements. The limited mixed fuel pathway has fewer efficiency requirements because this pathway uses less gas, and the most affordable pathway remains all electric with no additional energy efficiency requirements.
