LA County Code Title 31 adopts the California Green Building Standards Code (CALGreen, Title 24 Part 11) with local amendments. Mandatory measures cover construction-waste diversion, water-efficient fixtures, EV-ready parking, and indoor air quality for new buildings.
Title 31 of the LA County Code adopts CALGreen with county-specific amendments effective for permits issued after January 1, 2023, aligned with the 2022 code cycle. Mandatory residential measures include 65% construction-waste diversion, 20% reduction below baseline indoor water use, low-VOC paints and finishes, and EV-ready conduit for one parking space at single-family homes. Nonresidential additions over 1,000 sq ft trigger commissioning, daylighting, and bicycle-parking minimums. Voluntary Tier 1 and Tier 2 measures encourage cool roofs and on-site renewables. LACoDPW Building & Safety enforces through plan check; reach codes in some unincorporated areas push electrification.
Failure to provide CALGreen documentation triggers plan-check rejection and certificate-of-occupancy holds. Post-occupancy violations such as removing required low-flow fixtures result in administrative citations up to $500 per day under Title 26.
