  "articleBody": "### Building Code and CALGreen Impacts on ADU Design ADUs in Los Angeles County are generally subject to the **California Residential Code (CRC)**, the California Building Code (for some structural and accessibility provisions), and the **California Green Building Standards Code (CALGreen)**, along with local amendments adopted by the County or city. Building and Safety divisions within Los Angeles County Public Works and city departments reference these codes when reviewing ADU plans. CALGreen sets baseline green-building requirements, such as water-conserving plumbing fixtures, construction waste management, and indoor environmental quality measures for residential projects. For ADUs, this can translate into specific fixture flow rates, mechanical ventilation requirements, and insulation or air-sealing details documented in the construction drawings. The California Energy Code (Title 24, Part 6) adds mandatory and performance-based energy-efficiency criteria, with compliance often documented via energy modeling reports prepared by consultants or incorporated into architectural and mechanical design. Local amendments in Los Angeles County address seismic design, fire-resistance, and sometimes stricter energy or water standards. For example, ADUs near property lines may trigger requirements for **fire-resistance-rated walls** and limited openings, while units in designated Very High Fire Hazard Severity Zones may need ignition-resistant materials and defensible-space provisions consistent with state fire code and local fire department policies. An ADU design contractor must integrate these code requirements into layout, exterior design, and material selection. This can influence window placement, eave overhangs, siding and roofing materials, insulation levels, mechanical system sizing, and even structural framing strategies. By designing with these codes in mind from the outset, the contractor reduces plan-check corrections and ensures the ADU can be built without costly field changes to meet mandatory code standards.",
