California Title 24 2016 - Residential

California was among the first states to adopt building standards as a way to regulate energy consumption, in the form of Title 24.

Since its inception, the scope of this code's standards has increased. The latest policy, Title 24 2016, has significantly modified lighting needs in new and remodeled homes, so that all such homes in California must incorporate energy efficient lighting and controls.

Lutron products, such as dimmers and vacancy sensors, provide cost effective, easy-to-install solutions to save energy while meeting the Title 24 2016 requirements.
