Jurupa Valley FAQ
Can Jurupa Valley deny my garage-to-ADU conversion?
Generally no — state law (Gov. Code §66323) requires ministerial approval of ADUs created within existing accessory structures or single-family homes, including detached garages, provided basic health and safety standards are met.
Do I have to replace the garage parking when I convert it?
No. Gov. Code §66323 explicitly prohibits the city from requiring replacement parking when a garage, carport, or covered parking is demolished or converted to create an ADU.
Does the conversion still need building permits?
Yes. While the ADU approval itself is ministerial, the conversion must obtain building, electrical, plumbing, and mechanical permits and comply with the California Building Standards Code (Title 24).
