A construction scene in California highlighting the ongoing housing crisis.
California’s recently enacted legislation AB 130 pauses state and local building code updates for six years, aiming to address the housing crisis. However, critics warn this freeze may compromise safety and sustainability standards, potentially hindering progress towards climate goals. Local governments now face restrictions on implementing more ambitious building codes, stirring debate among supporters and environmental advocates regarding housing affordability and energy efficiency. The long-term consequences of AB 130 reflect the complexities of managing California’s pressing construction needs alongside environmental objectives.
In a significant move, California Governor Gavin Newsom recently signed into law AB 130, which aims to address the state’s ongoing housing crisis. This new legislation imposes a six-year pause on updates to state and local building codes, a decision that has drawn both interest and concern across various sectors.
The delay on building code updates is controversial because building codes play a crucial role in ensuring the safety and energy efficiency of structures. Notably, buildings are responsible for a quarter of California’s carbon emissions, making it essential for updated building standards to be in place for effective decarbonization efforts. The pause means that developers may not be able to utilize the latest energy-efficient designs and technologies that help reduce greenhouse gas emissions.
Under the latest energy code that will take effect on January 1, 2026, developers will be encouraged to build all-electric homes utilizing heat pumps and heat-pump water heaters. The California Energy Commission revealed that 80% of utility line extension requests in 2023 were for electric-only services, signifying a shift in how energy is consumed in residential areas. Moreover, 74 local governments across California have already adopted reach codes promoting all-electric new construction, showcasing a growing commitment to sustainability.
AB 130 restricts local jurisdictions from implementing their own ambitious building standards after an October 1 deadline. This pause on updates may hinder progress in many communities striving to enhance their building regulations in line with environmental goals. However, the law does allow for exceptions, permitting local governments to update codes during emergencies to safeguard health and safety.
Some jurisdictions are finding ways to explore code updates that might replace outdated air conditioning systems with modern heat pumps while potentially falling under AB 130’s exemptions. This indicates that while the law imposes restrictions, efforts to modernize specific aspects of building codes could still be pursued within the defined framework.
Proponents of AB 130 argue that the legislation will stabilize the housing market and tackle affordability challenges that many Californians face. Advocates believe that suspending building code updates will create more opportunities for housing construction, thus responding to the pressing demand for affordable living spaces.
Conversely, critics—particularly those from environmental groups—believe that freezing code updates will impede progress on climate objectives and emission reductions. Historical data shows that waiving building codes does not typically lead to lower housing costs, as evidenced by a 2015 study from UCLA. Additionally, robust building codes have consistently delivered significant energy savings for residents, amounting to over $100 billion in the past fifty years.
A 2019 analysis indicated that constructing all-electric homes generally costs between $3,000 and $10,000 less than building homes with traditional gas connections. The anticipated pause on building code updates could lead to tens of millions of dollars in lost utility savings for households that would benefit from more energy-efficient designs.
Legislative supporters, including assembly leaders, view this pause as a necessary step to address high housing costs and instabilities within the construction market. In the coming months, negotiations are expected to focus on additional funding and legislative measures that could promote electrification and sustainability beyond the restrictions imposed by AB 130.
As local governments prepare to navigate the implications of this new law, the implementation and effects of AB 130 will be closely monitored. Stakeholders across California are bracing for potential strategies that will allow for the advancement of housing construction while addressing environmental and safety standards.
