Existing law, referred to as the Density Bonus Law, requires a city or county to provide a developer that proposes a housing development within the city or county with a density bonus and other incentives or concessions, as specified, if the developer agrees to construct, among other options, specified percentages of units for lower income households or very low income households, and meets other requirements. Under existing law, the number of incentives or concessions granted to a development under the Density Bonus Law vary based on the percentage of affordable units within the development, or whether the development serves specified other target populations, as provided. Existing law establishes the Department of Housing and Community Development (HCD) in the Business, Consumer Services, and Housing Agency and requires it to administer various programs intended to promote the development of housing. Existing law establishes the State Energy Resources Conservation and Development Commission (the commission), consisting of 5 members, and establishes various duties and responsibilities of the commission relating to energy usage in the state.
