State and Local Building Efficiency Regulations & Policies: California

In this series, we’re exploring state and local building efficiency regulations to give you a bird’s-eye view of the policies that may impact your portfolio.

California. We saved the Golden State for last!

California has it all: great weather, natural beauty, and incredible biodiversity. It also boasts the largest population in the United States and a higher GDP than the United Kingdom. 

As the familiar saying goes, “with great power comes great responsibility.” Fortunately, when it comes to the environment, California has taken its responsibility seriously, and can truly be considered a global environmental leader. 

To wit: California is one of the largest energy consumers in the United States, second only to Texas. But unlike the Lone Star State, California has taken sweeping action at both the state and local levels, putting forth a slate of energy and environmental programs that are on par with leading European climate initiatives. It has set a 60 percent renewable energy target by 20301 and a GHG emissions reduction target of 40 percent (below 1990 levels) by 2030. It also aims to achieve carbon neutrality by 2045. In 2013, California became the first state in the nation to launch its own cap-and-trade program; the program now ranks as the fourth largest in the world.2 And that’s just the beginning. 

Since approximately 25 percent of the state’s greenhouse gas emissions come from energy use in commercial and residential buildings, California has established ambitious zero net energy goals. All new commercial construction and 50 percent of commercial building stock must achieve net zero by 2030.3 CALGreen is the first state-mandated green building code in the nation, and the California Energy Commission estimates that its 2019 standards will reduce the state’s residential building energy use by 50 percent and non-residential energy use by 30 percent. 

Additionally, cities and counties across California adopt new building codes every three years, and can choose to adopt local “reach codes” (i.e. codes that go beyond the state-mandated level) at any time.4 One such example is San Francisco’s Green Building Code (SFGBC), which has risen to the challenge by requiring all-electric new construction (see below for more info).

Building energy requirements and programs in California are extensive to say the least. To help make sense of it all, we’ve done the heavy lifting, compiling California’s key building energy requirements, policies, and plans in one place for easy reference. If your goal is to kick start a new west coast ESG initiative, keep reading for the full list.

California2019 CALGreen CodeEnergy Efficiency 
(New Construction)
CALGreen is California’s first green building code and first in the nation state-mandated green building code.  This code includes provisions to ensure the reduction of water use by 20%, improve indoor air quality, divert 50% of new construction waste from landfills, and inspect energy systems (i.e. heat furnace, air conditioner, mechanical equipment) for nonresidential buildings over 10,000 square feet to make sure that they’re working according to design. It is formally known as the California Green Building Standards Code, Title 24, Part 11, of the California Code of Regulations.  CALGreen was recently updated to include updated building electrification requirements. Became Mandatory in 2011; Recently updated in 2019
