Fremont FAQ
How often should I replace smoke detectors?
Replace the entire unit every 10 years regardless of type. Test monthly and replace 9-volt backup batteries annually. Sealed 10-year lithium alarms require no battery changes but still need replacement at 10 years.
Do Fremont ADUs need their own smoke alarms?
Yes. Every ADU is treated as a dwelling unit and needs alarms in each sleeping room, hallway, and story. A new ADU building permit requires hardwired interconnected alarms.
Livermore FAQ
Do I need alarms in older Livermore homes?
Yes. Retroactive state law requires alarms in all dwellings regardless of construction date, though hardwiring is only required in new construction or major remodels.
Who provides free smoke alarms in Livermore?
LPFD periodically partners with the American Red Cross on free alarm installations for eligible seniors and low-income residents.
