  "articleBody": "ADU additions in Los Angeles County must comply with the California Energy Code (Title 24, Part 6) and the California Green Building Standards Code (CALGreen, Title 24, Part 11), as enforced by County and city building departments. State energy regulations require new residential units to meet performance or prescriptive standards for insulation, fenestration, mechanical systems, and lighting. For ADUs, this typically means high‑performance windows with specified solar heat gain coefficients and U-factors, continuous wall and roof insulation values that meet or exceed climate zone requirements for the Los Angeles area, high-efficiency heating and cooling systems, and mandatory high-efficacy lighting throughout. Title 24 compliance is documented through energy modeling reports that must accompany permit applications, and inspectors verify insulation, window labeling, HVAC equipment, and duct sealing in the field. CALGreen establishes base-level environmental and resource efficiency requirements statewide. For residential additions and new small dwellings such as ADUs, this includes mandatory measures like low-flow plumbing fixtures, construction waste diversion, and pollutant control measures such as proper duct protection during construction and limits on volatile organic compound (VOC) content in paints and adhesives. Local building departments in Los Angeles County adopt and enforce these standards, and some jurisdictions overlay reach codes that go beyond state minima, such as encouraging all-electric design or EV charging readiness in new parking spaces. ADU contractors must coordinate with energy consultants to produce compliant documentation and integrate CALGreen checklists into their submittal packages, ensuring that specified products and construction practices align with California’s evolving sustainability requirements. Failing to account for these codes early can lead to redesigns, permit delays, or expensive mid-project changes during inspections.",
