Bill	Residential density and affordability.	The Planning and Zoning Law requires a city, county, or city and county to ensure that its housing element inventory, as described, can accommodate its share of the regional housing need throughout the planning period. The law also prohibits a city, county, or city and county from reducing, requiring, or permitting the reduction of the residential density to a lower residential density that is below the density that was utilized by the Department of Housing and Community Development in determining compliance with housing element law, unless the city, county, or city and county makes written findings supported by substantial evidence that the reduction is consistent with the adopted general plan, including the housing element, and that the remaining sites identified in the housing element are adequate to accommodate the jurisdiction's share of the regional housing need. The city, county, or city and county may reduce the residential density for a parcel if it identifies sufficient sites, as prescribed, so that there is no net loss of residential unit capacity.	us/states/ca	California Legislature	20172018	SB 166	California SB 166 (20172018)	bill	Residential density and affordability.	enacted	Skinner	8	31	7	2017-01-23	2017-09-29	openstates	ocd-bill/8ccf2cf2-3cc9-447f-9b2c-d42c5d72a7b3	http://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201720180SB166	65da0fc7ea18d1129787d8db92da14669b3158d3ba750379b7d952f1d81bb0dd	2026-07-01	https://data.openstates.org/daily/2026-07-01/public.pgdump	2026-07-06	reported	legislation bill us-ca
