CA SB9

Accessory Dwelling Units: ordinances.

Passed Senate Jesse Arreguin (D)
Plain English Summary

CA SB9 allows local governments in California to create ordinances that facilitate the construction of accessory dwelling units (ADUs), which are small housing units on the same lot as a primary residence. This legislation aims to increase housing availability and address the state's housing crisis by making it easier for homeowners to add these units. It modifies existing land use regulations to support the development of ADUs.

Supporters Say

Supporters of CA SB9 argue that this bill is a crucial step toward alleviating California's housing shortage by promoting the construction of more affordable housing options. They believe that by simplifying the process for homeowners to build ADUs, the state can encourage innovative housing solutions and provide more living spaces for families and individuals in need.

Critics Say

Critics of CA SB9 contend that the bill may lead to overdevelopment and strain local resources, as it could encourage the construction of too many ADUs in residential neighborhoods. They worry that this could change the character of communities and potentially lead to increased congestion and reduced quality of life for existing residents.
