Kent FAQ
How old can my smoke alarm be?
Replace smoke alarms every 10 years from the manufacture date printed inside. Older detectors miss real fires and generate false alarms.
Can I disable an alarm that keeps chirping?
No. Replace the battery or the unit. Disabling alarms violates fire code and voids landlord or insurance protections.
Renton FAQ
Do I need interconnected smoke alarms in my older Renton home?
Not until you do a permitted renovation over 1,000 dollars or add a bedroom. Otherwise battery-operated sealed 10-year alarms meet the minimum.
Are carbon monoxide detectors required?
Yes, in any dwelling with fuel-fired appliances like gas furnaces or a garage attached to living space, per RCW 19.27.530.
