Residential and Commercial Building Appliances

Rules for Space Heating, Water Heating, Cooking, and Other Building Appliances

The 2022 Air Quality Management Plan (AQMP) adopted in December 2022 includes control measures for the industrial, commercial, and residential sectors that are based on accelerated deployment of the cleanest possible technologies available. For residential and commercial buildings, the South Coast AQMD will develop and propose zero NOx emission standards for space heating, water heating, cooking, and other appliances for installation in new buildings and seek replacement at the end of useful life for units in existing buildings. One hurdle for the residential and commercial building appliances control measures is the cost of zero emission technologies and possibly infrastructure. To help mitigate the high upfront costs, the South Coast AQMD is also proposing incentive programs to encourage the early transition to zero emission appliances. This page is designed to provide direct links to building appliances-related material and serves as the central location for all information related to implementing control measures for building appliances.
