RHNA stands for Regional Housing Needs Assessment, a process mandated by California state law that requires cities and counties to plan and designate land for housing to meet the needs of people at all income levels. As part of this process, each City is assigned a specific number of housing units it must zone land for during a given planning period.
For the current 2021-2029 RHNA cycle, Chino Hills was initially assigned over 4,000 units. After many months of back and forth, and strong advocacy by the City Council and staff for a more realistic and balanced number, a reduced number of 3,729 units was approved. To avoid financial penalties and potential legal consequences, the City was required to zone enough land to accommodate that number in the updated General Plan.
It is important for the community to note that RHNA is not a construction mandate. The City does not build homes to meet the RHNA requirements, but it must plan and zone enough land to make housing development possible by private parties.
