Oakland FAQ
Do I need sprinklers for an ADU?
If the primary house has sprinklers, the ADU typically needs them too. Standalone detached ADUs may qualify for limited exceptions, but Oakland Hills fire zones often eliminate those exemptions.
Will sprinklers trigger from cooking smoke?
No. Residential sprinkler heads activate only when ambient air at the head reaches roughly 155 degrees Fahrenheit, which cooking smoke alone cannot do. Each head operates independently.
