A reach code is a local building energy code that “reaches” beyond or exceeds the state minimum requirements for energy use in building design and construction. They are adopted by city councils and county boards of supervisors with input from builders, contractors, and community members.
Reach codes typically promote that a new building be constructed with additional EV charging locations, electric water heating, space heating, cooking, or other appliances and that existing buildings receive upgrades at specific points like time-of-sale or when an old appliance is replaced.
