Solar and ADU Requirements in California: What You Need to Know (Copy)
Adding an Accessory Dwelling Unit (ADU) to your property in California has never been more popular—or more regulated. One of the latest changes affecting ADU projects is California's solar requirement. Since 2020, newly constructed residential buildings must comply with solar energy standards.
According to the California Energy Commission, all new construction—including ADUs detached from the main home—must include photovoltaic (PV) solar systems unless they qualify for a specific exemption. This rule aims to reduce energy use and greenhouse gas emissions statewide. However, this does not apply retroactively to converted garages or interior remodels of existing structures.
For homeowners in the Los Angeles area, where sun exposure is ample, integrating solar panels is both an environmental and economic advantage. With rising utility costs, solar can significantly lower monthly bills. There are also federal and state tax incentives available to offset initial installation costs.
It’s important to work with a construction partner who understands both local permitting and compliance standards. At KIND Construction, we help you navigate zoning laws, Title 24 requirements, and utility company regulations to ensure your ADU is compliant, efficient, and future-proof.
If you’re building an ADU from the ground up or converting a garage, solar integration should be considered during the initial planning phase to avoid expensive changes later. Our team handles everything from design and permitting to installation, making it easy to create a sustainable, code-compliant ADU that enhances your property value.
