Changes in State Law  

Due to the housing shortage in California, the State Legislature has passed significant housing-related laws in the past three years. In 2019, the legislature passed over 20 bills intended to fast-track housing production – including accessory dwelling units (ADUs). 

Updates to State Law expands areas and conditions under which ADUs can be built. The ADU Ordinance and ADU Handout both reflect the regulations permitted by current State Law. Be advised that this information is subject to change, as State guidelines and interpretations are typically issued after the enactment of the new law. 

Town of Danville Municipal Code

If an accessory dwelling unit or junior accessory dwelling unit is rented it shall be rented for terms longer than thirty (30) days, per the Danville Municipal Code.
