Community Development Agency


County of Marin Reach Code Update

On November 15, 2022, the board adopted Staff's recommended ordinance that updated the Green Building Code for unincorporated Marin.

For the Public, a high-level one-page summary of the County's (unincorporated) green building ordinance was created. 

For Project Applicants interested in anticipating green building requirements going into effect January 1, 2023, please review the adopted 2022 Green Building Code in detail. For ease, the following are one-page factsheets highlighting key requirements:

  1. All-Electric for All New Construction Buildings
  2. Electric Vehicle (EV) Readiness and Infrastructure for New Construction and Renovations
  3. Energy Efficiency and Electrification for Existing Single-Family Renovations
  4. Low-Carbon Concrete Requirements for All Building Projects (Adopted November 2019, deferred enforcement during shelter-in-place, and enforcement will resume January 1, 2023.)

The following is a model reach code (above and beyond state minimum) package for Marin policymakers, building officials, and the community to download, review, and use.
