2022 Green Building Model Reach Code and Ordinance Development

The team is developing a green building model (prototype) code that exceeds State minimum standards, otherwise known as a “reach code”. Learning resources and implementation and enforcement materials will also be available for all twelve jurisdictions countywide to download and utilize. All community stakeholders are encouraged to participate in community engagements. To access resources as development progresses until the end of 2022 and receive updates, please visit their site.
